6.3 Drainage test 6.3.1 Water leakage test

• TRANE"

After finishing the construction of drainage pipe system, fill the pipe with water and keep it for 24 hours to check whether there is leakage at joint section.

6.3.2 Water discharge test 1. Natural drainage mode(the indoor unit with outdoor drainage pump)

Infuse above 600ml water through water test hole slowly into the water collector, observe whether the water can discharge through the transparent hard pipe at drainage outlet.

2. Pump drainage mode 2.1 Disconnect the plug of water level switch, remove the cover of water test hole and slowly infuse about

2000ml water through the water test hole, be sure that the water will not touch the motor of drainage pump.

2.2 Power on and let the air conditioner operate for cooling. Check operation status of drainage pump, and then connect the plug of water level switch, check the operation sound of water pump and observe whether the water can discharge through the transparent hard pipe at drainage outlet. {In light of the length of drainage pipe, water shall be discharged about 1 minute delayed)

2.3 Stop the operation of air conditioner, power off the power supply and put the cover of water test hole back to the original place.

a. After stopped the air conditioner 3 minutes, check whether there is anything abnormal. If drainage pipes have not been distributed properly, over back-flow water shall cause the flashing of alarm indicator at remote-controlled receiving board and even water shall run over the water collector.

b. Continuously infusing water until water level alarmed, check whether the drainage pump could discharge water at once. If water level does not decline under warning water level 3 minutes later, it shall cause shutdown of unit. When this situation happens, the normal startup only can be recovered by turning down power supply and eliminating accumulated water.

Note: Drain plug at the main water-containing plate is used for eliminating accumulated water in watercontaining plate when maintaining air conditioner fault. During normal operation, the plug shall be filled in to prevent leakage.

6.4 Insulation work of drainage pipe Refer the introduction to the insulation engineering parts.

()

u

• TRANE"

Installation

► Eliminating the non-condensable gas (air) in system to prevent the components oxidizing, pressure fluctuation and bad heat exchange during the operation of system.

7.2 Selection of vacuum pump ► The ultimate vacuum degree of vacuum pump shall be -756mmHg or above. ► Precision of vacuum pump shall reach 0.02mmHg or above. 7.3 Operation procedure for vacuum drying Due to different construction environment, two kinds of vacuum drying ways could be chosen, namely ordinary vacuum drying and special vacuum drying.

7.3.1 Ordinary vacuum drying 1. When conduct first vacuum drying, connect pressure gauge to the infusing mouth of gas pipe and liquid

pipe, and keep vacuum pump running for 1 hour (vacuum degree of vacuum pump shall be reached -755mmHg).

2 ff the vacuum degree of vacuum pump could not reach -755mmHg after 1 hour of drying, it indicates that there is moisture or leakage in pipeline system and need to go on with drying for half an hour.

3 If the vacuum degree of vacuum pump still could not reach -755mmHg after 1.5 hours of drying, check whether there is leakage source.

4 Leakage test: After the vacuum degree reaches -755mmHg, stop vacuum drying and keep the pressure for 1 hour. If the indicator of vacuum gauge does not go up, it is qualified. If going up, it indicates that there is moisture or leak source.

7.3.2 Special vacuum drying The special vacuum drying method shall be adopted when: 1. Finding moisture during flushing refrigerant pipe. 2. Conducting construction on rainy day, because rain water might penetrated into pipeline. 3. Construction period is long, and rain water might penetrated into pipeline. 4. Rain water might penetrate into pipeline during construction.

Procedures of special vacuum drying are as follows: 1. Vacuum drying for 1 hour. 2. Vacuum damage, filling nitrogen to reach 0.5Kgf/cm2 .

Because nitrogen is dry gas, vacuum damage could achieve the effect of vacuum drying, but this method could not achieve drying thoroughly when there is too much moisture. Therefore, special attention shall be drawn to prevent the entering of water and the formation of condensate water.

3. Vacuum drying again for half an hour. If the pressure reached -755mmHg, start to pressure leakage test. If it can not reached the value, repeat vacuum damage and vacuum drying again for 1 hour.

4 Leakage test: After the vacuum degree reaches -755mmHg, stop vacuum drying and keep the pressure for 1 hour. If the indicator of vacuum gauge does not go up, it is qualified. If going up, it indicates that there is moisture or leak source.

8. Additional refrigerant charge ► After the vacuum drying process is carried out, the additional refrigerant charge process need to be

performed.

► The outdoor unit is factory charged with refrigerant. The additional refrigerant charge volume is decided by the diameter and length of the liquid pipe between indoor and outdoor unit. Refer the following formula to calculate the charge volume.

Note:

Diameter of liquid pipe (mm) ¢>6.35

Formula V=15g/mx(L-5)

V: Additional refrigerant charge volume (g). L : The length of the liquid pipe (m).

4>9.52

V=30g/mx(L-5)

► Refrigerant may only be charged after performed the vacuum drying process. ► Always use gloves and glasses to protect your hands and eyes during the charge work. ► Use electronic scale or fluid infusion apparatus to weight refrigerant to be recharged. Be sure to avoid

extra refrigerant charged, it may cause liquid hammer of the compressor or protections. ► Use supplementing flexible pipe to connect refrigerant cylinder, pressure gauge and outdoor unit. And

The refrigerant should be charged in liquid state. Before recharging, The air in the flexible pipe and manifold gauge should be exhausted.

► After finished refrigerant recharge process, check whether there is refrigerant leakage at the connection joint part.(Using gas leakage detector or soap water to detect).

7.4 Installation for the first time

Air and moisture in the refrigerant system have

undesirable effects as below:

• Pressure in the system rises.

• Operating current rises.

• Cooling or heating efficiency drops.

• Moisture in the refrigerant circuit may

freeze and block capillary tubing.

• Water may lead to corrosion of parts in the

refrigerant system.

Therefore, the indoor units and the pipes

between indoor and outdoor units must be leak

tested and evacuated to remove gas and

moisture from the system.

Gas leak check (Soap water method):

Apply soap water or a liquid neutral

detergent on the indoor unit connections or

outdoor unit connections by a soft brush to

check for leakage of the connecting points of

the piping. If bubbles come out, the pipes have

leakage.

1. Air purging with vacuum pump

1) Completely tighten the flare nuts of the

indoor and outdoor units, confirm that both the 2-way and 3-way valves are set to the

closed position. 2) Connect the charge hose with the push pin

of handle lo to the 3-way valves gas service

port.

3) Connect the charge hose of handle hi

connection to the vacuum pump.

4) Fully open the handle Lo of the manifold

valve.

• TRANE.

5) Operate the vacuum pump to evacuate.

6) Make evacuation for 30 minutes and check

whether the compound meter indicates

-0.1 Mpa. If the meter does not indicate

-0.1 Mpa after pumping 30 minutes, it

should be pumped 20 minutes more. If the

pressure can't achieve -0.1 Mpa after

pumping 50 minutes, please check if there

are some leakage points.

Fully close the handle Lo valve of the manifold

valve and stop the operation of the vacuum

pump. Confirm that the gauge needle does not

move (approximately 5 minutes after turning off

the vacuum pump). 7) Turn the flare nut of the 3-way valves about

45• counterclockwise for 6 or ?seconds

after the gas coming out, then tighten the

flare nut again. Make sure the pressure

display in the pressure indicator is a little

higher than the atmosphere pressure. Then

remove the charge hose from the 3 way

valve. 8) Fully open the 2 way valve and 3 way valve

and securely tighten the cap of the 3 way

valve.

2. Air purging by refrigerant

Procedure: 1 ). Confirm that both the 2-way and 3-way valves

are set to the closed position.

2). Connect the charge set and a charging

cylinder to the service port of the 3-way valve.

Warnings, Cautions and Notices

Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at appropriate intervals throughout this manual. Warnings are provided to alert installing contractors to potential hazards that could result in personal injury or death. Cautions are designed to alert personnel to hazardous situations that could result in personal injury, while notices indicate a situation that cou ld result in equipment or property-damage-only accidents.

Your personal safety and the proper operation ofthis machine depend upon the strict observance of these precautions.

ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout this literature. Read these carefully.

& WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

NOTICE: Indicates a situation that could result in equipment or property-damage only accidents.

Important Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the earth 's naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those conta ining Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

&WARNING R-410A Refrigerant under Higher Pressure than R-22! The unit described in this manual uses R-410A refrigerant which operates at higher pressures than R-22 refrigerant. Use ONLY R-410A rated service equipment or components with this unit. For specific handling concerns with R-410A, please contact your local Trane representative. Failure to use R-410A rated service equipment or components could result in equipment or components exploding under R-410A high pressures which could result in death, serious injury, or equipment damage.

This manual covers installation of the TWE air handlers. These air handler models incorporate a single slab coil assembly, improved application flexibility, servicing, maintenance accessibi lity and an improved accessory line. They are fully convertible, (vertical to horizontal discharge) without field removal of the coil assembly. They are shipped ready for horizontal installation.

All units have one drain pan that can be installed in any one of four positions. This allows for vertical or horizontal applications and right or left exit.

Important: All dual circuit (digit 7 = E) have an intertwined coil.

Installation Checklist

Unit Inspection

Initial Leak Test

An " Installation Checklist" is provided atthe end of the installation section of this manual. Use the checklist to verify that all necessary installation procedures have been completed. Do not use the checklist as a substitute for reading the information contained in the manual. Read the entire manual before beginning installation procedures.

Inspect material carefu lly for any shipping damage. If damaged, it must be reported to, and claims made against the transportation company. Compare the information that appears on the unit nameplate w ith ordering and submittal data to ensure the proper unit was shipped. Available power supply must be compatible with electrical characteristics specified on component nameplates. Replace damaged parts with authorized parts only.

All TWE units are shipped with a holding charge of nitrogen in each circuit. Remove the access panel shown in Figure 13, p. 21 . Locate the liquid line or suction l ine access valve for each ci rcuit. Install gauges to determine if the circuits are still pressurized. If not, the charge has escaped. Repair as required to obtain a leak-free circuit.

Lifting Recommendations

6

& WARNING Improper Unit Lift! Each of the cables (chains or slings) used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements may cause equipment or property-only damage. Failure to properly lift unit could result in death or serious injury. Refer to Table 1 and Table 2 for unit weight.

NOTICE Equipment Damage! Use spreader bars to prevent straps from damaging the unit. Install the bars between lifting straps, both underneath the unit and above the unit. This will prevent the straps from crushing the unit cabinet or damaging the unit finish.

Pre-Installation

The final position for the air handler must be dictated by required service access to it, weight distribution over structural supports, and by the locations of electrical, refrigerant and condensate drainage connections. After this is determined, the following preparations should be made.

Repositioning Drain Pan

These air handlers come with one drain pan that can be installed in any one of four positions; this allows for vertical or horizontal application and right o r left condensate line connection. The drain pan can also be easily removed for periodic cleaning.

Note: Important! All air handlers are shipped with the drain pan installed in the horizontal position and the connection on the left side (as shown in Figure 1. If an alternate position is required, the drain pan should be repositioned before setting the air handler.

Refrigerant Piping

Evaporator Coil Orientation Important: Applies only to TWE126/ 150 and 156/ 180 when positioned for vertical upflow. Unit

is shipped in the horizontal position. If installing in the vertical position, the coil must be reoriented by rotating the coil 4 degrees (control box side) from the shipped position. See instructions and Figure 4 below.

Process for reorienting evaporator coil on TWE126; 150, 156 and 180 only. 1. Remove screws from top evaporator coi l bracket (bracket that attaches coi l to cabinet and runs

the length of the unit).

2. Rotate evaporator co il approximately 4 degrees clockwise - looking from the control box end (see Figure 4). When the evaporator coi l is rotated, the lower set of evaporator coil bracket holes wi ll align with the support bracket (from which it was originally fastened).

3. Reinsert screws in evaporator coil bracket.

Preparation

NOTICE Unit Damage!

Rotate 4° clockwise

Do not apply heat to remove seal caps until the gauge port cores have been removed. If seal caps are intact, application of heat may generate excessive pressure in the unit and result in damage to the coil or expansion valve.

The air handler is designed so that refrigerant piping can enter from either the right or left hand side. It is shipped with the intent that the refrigerant lines will enter from the left hand side. To convert to right hand entry, unbraze the elbow on the suction line and rotate 180° and rebraze.

Important: Access to refrigerant lines is limited in all horizontal and some vertical applications. Therefore, refrigerant lines should be stubbed out and temporarily capped prior to setting the air handler. Protect adjacent surfaces from heat damage when brazing in and around the air handler.

Installations, Limitations and Recommendations

12

NOTICE System Component Damage! Properly insulate all refrigerant gas piping to prevent possible water damage due to condensation and to prevent capacity loss and possible compressor damage.

The general location of the air handler is normally selected by the architect, contractor and/or buyer. For proper installation the following items must be considered.

• Availab le power supply must agree with electrical data on component nameplate.

• If external accessories are insta lled on the unit, additional clearances must be provided.

• All duct work should be properly insulated to prevent condensation and heat loss.

• Refrigerant gas piping must be insulated.

It is recommended that the outline drawings (Figure 6, p. 14 - Figure 13, p. 21 ) be studied and dimensions properly noted and checked against the selected installation site. By noting in advance which features are to be used, proper clearance allowances can be made for installation and possible future service.

Important: When installing these units "free standing" with discharge grills and isolators, a top support with isolator should be added to prevent tipping. Support and isolator can be attached to a wall or other appropriate structure.

Important: If adding external accessories to the unit, additional clearances must be considered for the overall space needed.

For installation of accessories avai lable forth is air handler, follow the instructions packed with each accessory.

Installation

Horizontal Suspension

If the air handler w ill be suspended, use a suspension mounting kit to isolate the unit from the structure. This is usually accomplished through the use of spring or rubber isolators, which are offered as an accessory. Mounting rods must be field supplied. Isolator selection is dependent upon total unit weight including accessories. Approximate unit weights are provided in Table 1 and Table 2, p. 7.

NOTICE Equipment Damage! Before hanging the unit on suspension rods, reinforce the cabinet around the suspension holes by using a large washer inside the cabinet. Washers should be between the skin of the air handler and the nut on the suspension rod.

Align holes in the cabinet with structural supports and secure suspension rods to the structure, then to the air handler cabinet. If hole locations do not permit proper alignment with existing structure, it may be necessary to field fabricate cross members on existing structural beams.

Note: When other than bottom return is to be used, side panel removed for return duct installation must be secured over the bottom opening.

Leveling

This air handler has a double sloped drain pan. In order to assure proper drainage along the length of the drain pan, it is important to have the unit properly leveled. Be sure the air handler is level.

Auxiliary Drain Pan

A field fabricated, auxiliary drain pan should be installed under the unit for all horizontal appl ications and when air handlers are installed above ceil ings or in other locations where condensate overflow may cause damage. This drain pan will eliminate any excess condensation that may be due to extreme humidity or an obstructed drain in the primary drain pan. Drain l ines from this pan must be installed, but should not be connected to the primary drain line from the unit. Isolate the auxiliary drain pan from both the air handler and the structure.

& WARNING Fiberglass Wool!

Product contains fiberglass wool. Disturbing the insulation in this product during installation, maintenance or repair will expose you to airborne particles of glass wool fibers and ceramic fibers known to the state of California to cause cancer through inhalation. Glass wool fibers may also cause respiratory, skin or eye irritation.

Precautionary Measures • Avoid breathing fiberglass dust.

• Use a NIOSH approved dust/mist respirator.

• Avoid contact with the skin or eyes. Wear long-sleeved, loose-fitting clothing, gloves, and eye protection.

• Wash clothes separately from other clothing: rinse washer thoroughly.

• Operat ions such as sawing, blowing, tear-out, and spray 1ng may generate fiber concentrations requiring additional respiratory protection. Use the ap,,propriate NIOSH approved respirator in these situations.

First Aid Measures

Eye Contact - Flush eyes with water to remove dust. •t symptoms persist, seek medical attention.

Skin Contact - Wash affected areas gently with soap and warm water after handling.

Refrigerant Piping

SSA-SVX06A-EN

Installation, brazing, leak testing and evacuation of refrigeraint lines are covered in the installation instructions packaged with the outdoor unit. Read the instruc tions before beginning insta llation of refrigerant l ines.

Locate cloth bag(s) attached to the refrigerant tube of the co11that c ontains a stainless steel clamp and insulation material (approximately 9" long by 4" wide) for each refrigerant circuit. This is for attaching and insulating the expansion valve bulb (s) to the, suction line(s).

On air handlers that will have refrigerant lines entering t he c abinet from the left side, remove the split rubber grommet from the knockout in the end of the air handl er. Uncoil the cap tube with the bulb attached at the expansion valve and place the gromme t on the cap tube. With the grommet around the tube, push the bulb through the hole and positic:m the grommet back into its original position (one bulb and cap tube on single circuit units and tll<\lo bulbs and cap tubes on dual circuit units).

Attach the bulb(s) on a horizontal section of tube where the entire length of the bulb is in contact with the tube, (see Figure 14, p. 31 ) approximately 45 degrees off vertica l (a 10 or 2 o'clock position), 10 to 12 inches outside of the air handler.

On air handlers that wi ll have refrigerant l ines entering the cabinet from the right side, the bulb(s) should be attached to the suction tube(s) inside the cabinet in the same manner as above, approximately 10" from the right end of the unit.

After attaching to the suction line(s), either inside or outside of the cabinet, wrap the insulation around the bulb(s) and suction tube(s). Refrigerant piping should be insulated.

NOTICE Equipment Damage!

Condensate Piping

Filters

The drain pan condensate connection is a female slip joint type for 1" Schedule 40 PVC pipe. Use PVC cement and tubing as required (field supplied) to construct a trap. A union or flexible tubing and clamps may be installed if the drain pan is to be removed periodically for cleaning.

Important: When air handler is installed in the vertical position and close proximity trapping of condensate is required, use of a subbase accessory to raise the air handler for clearance of the drain trap is recommended. See Figure 15 for a typical drain trap assembly.
