Before installing the Drain-All, Inc.Model 1700TM, a review of the followingitems will help make the right decisionregarding options which could be used toensure long-term maintenance free oper-ation.

RUST AND SCALE

Even though the Drain-All, Inc. Model1700TM is designed for handling rust andscale, it is recommended that the systembe blown down after all piping isinstalled and before the Model 1700TM isconnected to the piping. The Model1700TM, with a large, smooth, liquid flowpath, easily handles contaminates in theliquid once the system is in operation. Ifthere is excessive rust and scale on a con-tinuous basis, consider using the RustHandlerTM designed for compressed airsystems that have extremely heavyamounts of rust and scale.

CONTROL AIR & BALANCE LINE

The control air line provides air throughthe sealed center tube to operate the aircylinder. Clean dry air should be used forthis control air supply. The balance lineprovides a means to handle the displacedair from the reservoir as the liquid entersthe reservoir. The control air line and thebalance line are two separate lines whichhave nothing in common with each otherand should never be connected to eachother in any way. Do not tie them togeth-er with a tee fitting.

CONTROL AIR

Control air pressure requirements vary byproduct and must be regulated withinspecifications provided in the product’sInstallation Guide. If the specified pres-sure for control air cannot be supplied inyour application, contact your distributorfor information on control air optionsoffered by Drain-All, Inc. to accommo-date your available control air pressure.

BALANCE LINE

The balance line must have either (1)exactly the same pressure as the vesselbeing drained or (2) slightly less pressurethan the vessel being drained.

The same pressure is achieved when thebalance line is tied back into the vesselbeing drained, such as connecting thebalance line at a tee fitting on the vessel’spressure gage or access port. A slightlylower pressure may be achieved by locat-ing the balance line connection on the airheader pipe a few feet downstream fromthe vessel being drained. When hookingthe balance line to an air header, connectit to the header prior to any other vesselattached to the header.

If there is absolutely no place to connectthe balance line into the air system, or ifa temporary installation is to be madewhile waiting for the next shutdown to tiein the balance line, the balance line canbe vented to atmosphere. Install the nee-dle valve that comes as a component ofthe installation kit into the port on top ofthe Model 1700TM where ''Balance Line''is indicated. Then follow the start-upinstructions for adjusting the opening ofthe balance line needle valve. There willbe very little air loss to atmosphere.

NO MANIFOLDS

There cannot be multiple system drainsthrough a manifold to one Model 1700TM.This will not work because all systemdrains will not be of the same pressure.Therefore, the liquid from the higherpressure drain lines will bypass theModel 1700TM and flow backwards up thelower pressure drains. Installing checkvalves on system drains is not a solutionbecause pressure variations which inhibitproper operation will still be present.Proper installation of the balance line isnot possible with multiple drains hookedup through a manifold.

CORROSION

There are Drain-All, Inc. products avail-able which include corrosion resistantcoatings and materials. If the applicationenvironment is highly corrosive, checkthese products and options to determineif they should be specified. Also availableare Drain-All, Inc. products which handlehigher pressures and temperatures.

INSTALLATION STEPS

1. Prior to installing the Model 1700TM,blow down the vessel being drained toremove excessive rust, scale, and dirtknocked loose during piping installation.

2. Remove the Model 1700TM from thebox and set it in an upright positionwhere it will be connected. Most Drain-All, Inc. products do not have to besecured. Larger volume and higher pres-sure products may require some form ofmovement restraint. To ensure properoperation in all installation layouts, thetop of the Model 1700TM should be lowerthan the bottom of the vessel beingdrained.

3. Using 1/2” pipe, connect the vesselbeing drained to the 1/2” liquid inlet onthe base of the Model 1700TM. Be sure toinstall a shut-off valve and a bypass valvebetween the vessel being drained and theModel 1700TM. This will allow easyremoval of the Model 1700TM "on therun" during any preventive maintenanceactivities. After installing the piping,close the inlet shut-off valve.

4. Using 1/2” pipe, connect the Model1700TM discharge outlet to a sealed drainpipeline or enclosed/covered trough. Thedischarged liquid is under pressure andcan splash back if directed downwardtoward the bottom of a simple, shallow,open trough-type floor drain.

5. Connect the balance line from theModel 1700TM to the appropriate connect-ing point on the vessel being drainedusing the tubing and needle valve provid-ed in the installation kit. After installingthe balance line, close the balance lineneedle valve.

6. Using the tubing and needle valve pro-vided in the installation kit, connect thecontrol air supply line to the control airfilter inlet on the Model 1700TM. Alwaysuse the cleanest and driest air possible toensure long term maintenance free oper-ation. After connecting the control airline, close the control air needle valve.

INSTALLATION


START-UP

1. Close control air line and balance lineneedle valves as well as inlet isolationshut-off valve.

2. Bring up system pressure.

3. Fully open control air needle valve.Check for leaks in control air line. Pushthe “Push to Test” button on top of theModel 1700TM to verify the air cylinderstrokes, opening the discharge ball valve.Leave control air needle valve open.

4a. Applications where the balance lineis connected back to vessel beingdrained. Fully open the balance line nee-dle valve. Check for air leaks on balanceline and fittings. Leave balance line nee-dle valve fully opened. The needle valvecan be used as an isolation shut-off valve.

4b. Applications where the balance lineneedle valve is vented to atmosphereor connected to a header pipe leavingthe vessel being drained. Open the bal-ance line needle valve only enough toensure a small amount of air can flowthrough it. This will be adjusted in a laterstep.

5. Gradually open the inlet isolation shut-off valve to the full open position toallow liquid to enter the Model 1700TM.The reservoir will fill until the float israised to the upper position actuating thecontrol circuit extending the air cylinderand opening the ball valve. Once the dis-charge starts, the liquid level in theDrain-All reservoir begins to lower. Thislowers the float back to its original posi-tion which deactivates the control circuitclosing the ball valve.

6a. Applications where the balance lineneedle valve is vented to atmosphereor connected to a header pipe leavingthe vessel being drained. With liquid inthe reservoir and the liquid discharge ballvalve in the closed position, close thebalance line needle valve. As you slight-ly open the balance line needle valve,look into the translucent sleeve justabove the inlet port and look for a trickle

of small bubbles. Continue to open theneedle valve until you see these bubblesindicating a proper setting for the balanceline needle valve. Remember that bub-bles will only be seen if there is a pres-sure differential (when balance line isvented to atmosphere or to a header leav-ing the vessel being drained).

6b. When the balance line is connectedback to the vessel being drained, there isno pressure differential between the inletand balance line and there will be nobubbles in the liquid. In this applicationkeep the balance line needle valve in thisconnection fully open. The top of theModel 1700TM must be below the bottomof the vessel being drained.

7. Once properly installed, no furtheradjustments to the Model 1700TM are nec-essary. The Model 1700TM is fully auto-matic, discharging on demand as neededwhen liquid accumulates.

TROUBLESHOOTING

1. Water does not enter.

A. Balance line isolation shutoff valve isclosed which does not allow liquid toenter the Model 1700TM. Solution: Adjust balance line needlevalve per installation instructions.

B. Liquid inlet shut-off valve is closed. Solution: Fully open liquid inlet shut-offvalve.

C. Vessel drain, and/or pipe from vesseldrain to Model 1700TM inlet is plugged. Solution: Clear obstruction.

D. Location of balance line connectioncauses higher balance line pressure thanliquid inlet pressure. Model 1700TM is“back flowing”. Solution: Refer to installation instruc-tions for proper balance line installation.

2. Fills and will not drain.

A. Control air line needle valve is closed,or not fully open. Solution: Fully open control air needlevalve to full open.

B. Lack of adequate air pressure on con-trol air line. Solution: Provide more than the mini-mum required PSIG to control air lineconnection per the product specification.If there is not enough control air pressureavailable, there are lower control airpressure options available - contact yourdistributor for details.

C. Hole in valve stem clogged. Solution: Clear obstruction. Do not alterhole diameter.

D. Filter element clogged or dirty. Solution: Replace part.

3. Discharge ball valve stays open.

A. Center tube magnet installed upsidedown, i.e., north and south polesreversed. Solution: Reinstall center tube magnetrotating it 180 degrees, end for end.

B. Bleed hole for air cylinder clogged.Solution: Clear bleed hole on side of aircylinder located on opposite side fromcontrol air connection to the cylinder. Donot alter hole diameter.

C. Center tube magnet stuck or not prop-erly sealing against valve stem. This canresult from excessive oil and water con-taminates allowed to get into the controlair lines and then into the center tube,thereby coating the center tube magnetand causing it to stick. Solution: Clean center tube and centertube magnet and reassemble. Also, ifpossible, connect the control air line to aclean dry air source which will preventreoccurrence.

4. Excessive bubbling action in reser-voir.

A. Air leak in balance line and/or fittings. Solution: Refer to installation instruc-tions and start-up procedures.

B. Balance line needle valve opened toofar. Solution: Adjust balance line needlevalve per installation instructions.

PRODUCT TECHNOLOGYHOW IT WORKS

Page 5

FIGURE 1: START OF CYCLE

The float (1) with a magnet molded in (2)is sitting on the base and is at the lowestlevel. The float magnet exerts a magneticforce repelling the center tube magnet (3)upward, holding it seated against an ori-fice in the lower end of the valve stem(4). This retains the control air coming inthrough the control air filter (5) in thecenter tube (6). The control air circuitincluding the center tube magnet andvalve stem are isolated from the liquidheld in the reservoir (7). The air cylinder(8) is in the home position and the dis-charge ball valve (9) is closed.

There is always a residual amount of liq-uid (10) left in the bottom of the reservoirafter each discharge cycle. The Model1700TM stops discharging before all accu-mulated liquid is removed providing aliquid seal that conserves expensive com-pressed air. Liquid (11) flows through theinlet port (12) and into the reservoir tostart the fill cycle. Liquid continues to fillthe reservoir until the float has displacedenough liquid to become buoyant and thefloat pops upward to the upper positionshown in Figure 2.

FIGURE 2: START OF DISCHARGE

The liquid flows in and raises the float toits highest position as shown. The floatmagnet is raised up past the center tubemagnet and repels the center tube magnetdownward opening the orifice in thevalve stem. This allows the control airheld in the center tube to flow through thecontrol air circuit to the actuating cylin-der. The actuating cylinder extends andopens the ball valve starting the dischargeof accumulated liquid.

When the correct amount of liquid hasbeen discharged, leaving a liquid seal inthe reservoir, the float has been loweredto a point where the float magnet is belowthe center tube magnet. In this position,the float magnet repels the center tubemagnet back upward against the valvestem orifice, which seals off the controlair flow to the actuating cylinder. Thecylinder has a spring which then returnsthe cylinder to its home position, closingthe discharge ball valve. The discharge isstopped as shown in Figure 1 and the fillcycle repeats.

THE BALANCE LINE PORT

The balance line port is a hole throughthe head of the Model 1700TM that goesinto the reservoir. This port allows the airtrapped in the top of the reservoir tomove out of the reservoir to allow liquidto enter the reservoir through the inletport. If there were no balance line port, asliquid entered the reservoir under pres-sure, the air trapped in the top of thereservoir would be compressed until itwas the same pressure as the liquid com-ing in and the unit would stop filling.

There are three methods of connecting tothe balance line port. The most effectiveis to connect it back to the vessel beingdrained as shown in the illustrationsabove. In this configuration, the reservoiris at the same pressure as the vessel beingdrained and the liquid is filling by gravi-ty. In this case, the top of the Model1700TM must be lower than the bottom ofthe vessel being drained. The balance linecan also be attached to a header pipeleaving the vessel being drained or vent-ed to atmosphere using a needle valve.Venting to atmosphere uses very little airif the needle valve is adjusted properly.

Where should a Drain-All be installed?

At liquid accumulation points within asystem at compressors, air receiver tanks,intercoolers, aftercoolers, dryers, separa-tors, filters and drip legs.

Is this an oil-water separator?

No. Drain-All is a liquid drain and it willdrain oil, water, and particulates from thecompressed air system. Once this isaccomplished, the discharge should bepiped to an oil-water separator for finalprocessing.

Does this replace a dryer?

No. Drain-All works in conjunction witha dryer. Dryers typically convert watervapor in the compressed air into liquidwhich is usually discharged through asmall automatic drain device integral tothe dryer. These small automatic drainsare often prone to clogging and failure.When this occurs, such drains are nor-mally replaced with Drain-All unitswhich do not clog. A dryer prepares themoisture for removal from the system bycondensing it. It is the job of the reliableDrain-All to ensure that the liquid isactually discharged from the air system.

Is it mandatory to use a balance line?

Yes. The balance line provides a means tohandle the displaced air from the reser-voir as the liquid enters the reservoir.

What is the capacity?

In each application, based on pressuresand piping layout for that application, aDrain-All model will eject a specificamount of liquid on each cycle. Thisvaries by model and application.

What size compressor can it handle?

There are Drain-All models that willfunction effectively on any size compres-sor, compressed air system, atmospheric,or vacuum system. Provide your distrib-utor with specifications on the pressureand capacity of liquid you need to handleand an appropriately sized Drain-All canbe selected for your application.

Can one Drain-All be used to drainmultiple tanks and/or compressor sys-tems?

No. They will not all be of precisely thesame pressure level and the liquid wouldaccumulate in the lowest pressure drainor system thereby bypassing the Drain-All. Also, the use of check valves in mul-tiple drains to one Drain-All installationwill not make this work properly.Always install one Drain-All for eachitem of equipment to be drained.

Can a Drain-All be used in systemswith pressure greater than 170 PSIG?

Yes. Higher pressure models are avail-able. If the control air comes from higherpressure systems, a pressure regulator onthe control air line may be used and set atthe proper control air pressure or option-al control air components can be orderedto accommodate higher pressures.

Can the balance line and the controlair line be hooked together via a teeconnection?

No. Do not do this. Each of these airlines has its own specific purpose andshould never be tied together. The con-trol air should be the cleanest driest airavailable since it supplies air to the con-trol circuit to operate the pneumatic actu-ating cylinder which functions best andlasts longer if clean dry air is used.

The balance line allows the air in thereservoir to move out leaving room in thereservoir for the incoming liquid. This aircontains moisture that would be drawnacross a tee fitting tied to the control airline and be pulled directly into the con-trol air circuit, which can damage controlair pathways and the air cylinder.

Is there only one model Drain-All?

No. There are models for a wide range ofspecial applications. Dimensional alter-ations, design changes, componentoptions and special materials or coatingsare used in models to withstand high tem-peratures and highly corrosive environ-ments as well as accommodate high vol-ume discharge requirements.

What if the system has an abundanceof metallic trash?

Before installing the Drain-All, blowdown the system being drained to elimi-nate as much existing loose scale as pos-sible. The large, smoothly contoured flowpaths in Drain-All units handle normallevels of debris found in most applica-tions. Should there be an excessiveamount of debris such as heavy rust, askyour distributor about Drain-All’s RustHandlerTM Model designed for that kindof severe duty.

How can the Drain-All be used as aninstrument to gather data on conden-sation in a compressed air system?

With the use of Drain-All’s optionalcycle counter, the Drain-All can provideaccurate data on the amount of liquid thata compressed air system generates. Thisis very useful when buying new com-pressed air system equipment because aDrain-All with a cycle counter is abenchmarking instrument. Since theDrain-All discharges the same amount ofliquid on every cycle, knowing the num-ber of cycles over a specific period oftime under specific temperature andhumidity conditions provides the abilityto track liquid production. This bench-marking can be correlated to ongoingchanges in ambient temperature andhumidity conditions to identify variancesin liquid production indicating changeswhich need investigation. Too few cycleswould mean not enough liquid is reach-ing the Drain-All and should be investi-gated. Too many cycles would mean toomuch liquid is being made or too muchliquid from somewhere is reaching theDrain-All and should be investigated.Knowing the amount of liquid a systemproduces is also essential for properlysizing oil-water separators.

FREQUENTLY ASKED QUESTIONS


CLOGGED DRAINSOther drain devices with small orificesand poppet style valves are prone to clogwhen solid debris is present. Each Drain-All has a large, smooth liquid flow pathand discharge port as well as a heavyduty shear action ball valve designed toalleviate this problem.

ELECTRICITYTimer valves require electricity. There isa cost for installing and maintaining theelectric outlets they require as well anongoing operating cost of electricity yearafter year. Drain-All requires no electric-ity to operate since it is totally pneumaticand can be easily installed at any pointalong the compressed air system provid-ing low cost installation and ongoingoperation.

RELIABILITYDrain-All’s cycling is controlled by apatented magnetic interaction with atotally pneumatic control circuit. Whileother pneumatic drains have a complexlever action “toilet bowl” type internalfloat with many parts, there are few mov-ing parts in the Drain-All. Since theDrain-All is totally pneumatic, it is notaffected by power outages or the othervulnerabilities of electrical devices suchas timer solenoid valves, motorized ballvalves or electrically operated float traps.

BYPASSED DRAINSSmaller drains become plugged so oftenthat cleaning them out becomes a verylabor intensive operation. To avoid con-stant cleaning, there is a temptation tobypass the inadequate drain and crackopen a manual bypass valve causing it todrain constantly thus causing a constantflow of wasted compressed air. Drain-All’s anti-clog design eliminates thetemptation to bypass the drain.

SYSTEM BLOW DOWNManually operated drains, timer solenoidvalves, motorized ball valves or electri-cally operated float traps blow away largequantities of expensive compressed air.Manually operated drains waste consid-

erable compressed air because most oper-ators feel it is necessary to have the drainopen an extended period of time in orderto get all the liquid out. Timer valves arealmost always set to be open longer thannecessary in order to get all of the liquidout and this also passes large quantities ofcompressed air down the drain. Drain-All avoids this waste of compressed airand the resulting pressure drop in thecompressed air system by maintaining aliquid seal in the bottom of the Drain-All’s reservoir between each cycle.

AMOUNT OF LIQUIDManual draining and timer valve drainingdo not provide any information on thequantity of liquid being produced in thecompressed air system.

Each Drain-All model discharges a spe-cific amount of liquid on each cycle in agiven application. With the addition of aDrain-All cycle counter on the Drain-Allunit, it is easy to track how much liquid isproduced over any period of time. This isparticularly important for benchmarkingsystem equipment performance and per-forming trend analysis. For example, it isessential to know the quantity of liquidproduced by a compressed air system toproperly size oil-water separators.

The counter coupled with a Drain-Allunit is an instrument. Once installed, itprovides tracking of the number of cyclesfor periods of time at different ambienttemperature and humidity conditions.This data can be plotted on a chart.During operations thereafter, a check onthe number of cycles per time period ofactual operation compared to the chartfor a given temperature and humidity willshow if the correct amount of liquid isbeing received by the Drain-All. Toomany cycles compared to the chart indi-cates excessive liquid is being producedsomehow and should be investigated.Too few cycles indicates that not enoughliquid is being produced and this tooshould be investigated.

OVER-DRAININGManual drain valve operation and timervalves are usually set for overkill in fre-quency and duration of drainage times inorder to be certain that no liquid accumu-lates in the system. This results in wasteof expensive compressed air. Drain-All isdemand activated and drains only whenthe liquid reaches the predetermined trig-ger point. The Drain-All does not over-drain or blow down the system.

UNDER-DRAININGTimer drains must be preset to establishthe frequency and duration of drainage.The settings are vastly different in peri-ods of high humidity from what theywould be in periods of low humidity. It iscommon for this adjustment to be over-looked in the transition from winter tosummer. Therefore, the settings are inad-equate to handle the high summer quanti-ties of liquid which results in excess liq-uid accumulation in the compressed airsystem. This liquid often backs up andcan cause damage to dryers, compressorsand hand tools that is expensive to repair.The Drain-All is designed to cycle asneeded when liquid accumulates andrequires no adjustments from season toseason.

LIQUID REMOVALThe air pressure in the system beingdrained forces the liquid out of the Drain-All reservoir. Because the power of theair system is behind it, the discharge canbe directed upward, to a containmentvessel, oil-water separator or an overheaddischarge piping system.

In the drawing below, there is a dotted lineindicating the level of the trigger level of thetrap. This is the height the condensate mustreach in the trap to start the discharge cycle.

When the balance line port is connectedback to the vessel or header pipe, asshown in the drawing above, the trap isfilling by gravity. In these applications thebottom of the vessel must be higher thanthe top of the trap so that the condensateflows by gravity down and out of the ves-sel into the trap.

When the bottom of a vessel beingdrained is lower than the trigger point inthe trap, as shown in the drawing to theright, do not connect the balance line portto the vessel or header pipe.

In the drawing to the right, if the balanceline were connected to the vessel or head-er pipe, the condensate would be filling

the trap by gravity. With the bottom of thevessel being lower than the top of the trap,this would result in condensate backing up inthe vessel to the same height of the conden-sate in the trap. When the condensate reached

the trigger level in the trap, shown by the dot-ted line, the condensate would also reach thesame height in the vessel (the same dottedline).

In an application where the bottom of thevessel is lower than the top of the trap, thebalance line must be vented to atmos-phere. Venting a small amount of air fromthe trap reservoir to atmosphere results ina pressure differential in the trap reser-voir. This allows the pressure in the ves-sel to push the condensate downward, outof the vessel, and up into the trap. Thisachieves proper filling of the trap whileremoving all condensate from the vessel.Send application questions to:

INSTALLATION LOCATIONS

Method -1Connect the balance line port to the vesselproducing the condensate. This is the pref-ered method since it is a closed-loop arrange-ment. In the first four applications above, thebalance line is connected back to the vesselthat is producing the condensate. The pres-sure on the incoming condensate to the trapand the pressure in the balance line are thesame and the trap is filling by gravity. For thismethod, the top of the trap must be below thebottom of the vessel being drained.

Method -2Connect the balance line port to the head-er pipe leaving the vessel producing thecondensate. This is an alternate method toMethod-1 when there is no convenient loca-tion to connect the balance line to the vessel.This is shown above in the drip leg applica-tion. In the case of a dryer, however, connect-ing the balance line to the header pipe leavingthe dryer essentially results in a bypass of thedryer function. The condensate from thedryer would have a path up the balance lineand back into the flow of dry air leaving thedryer. That would not be desirable.

Method -3Vent the balance line port to atmosphereusing a needle valve inserted in the balanceline port and slightly opened. This can beused on any application but must be usedwhen the bottom of the vessel is lower thanthe top of the trap. The needle valve shouldbe opened slightly to a point where only asmall amount of air can be felt leaving theneedle valve. This method provides a pres-sure differential in the trap reservoir and con-densate is blown into the reservoir instead offilling by gravity.

VESSELS WITH BOTTOM LOWER THAN THE TRAP’S TRIGGER LEVEL

THERE ARE THREE METHODS USED TO CONNECT THE BALANCE LINE PORT

1. Connect balance line to vessel being drained, to header leaving vesssel being drained, or vent to atmposphere - do not manifold balance lines together.

3. Bring control air from clean dry source downstream of dryer if possible, can manifold control air lines together.2. Balance line balances reservoir of trap to vessel being drained. Control air operates air cyclinder. These two should not be connected together.

Control air from clean dry airsource if at all possible
