In case the vertical distance between the external condenser and the CoolMaster is more than 3 meters there should be provide an so called “Oil trap” in the hot gas pipes. At every next difference in level of 9 meters there should be provide an extra Oil trap. (See drawing) The external condenser must be set up at the same height or higher than the CoolMaster. NOTE! The connection between CoolMaster and the external condenser should not exceed 15 meters! (for piping diameters, see flow scheme)

NOTE! THE PIPES BETWEEN THE CoolMaster AND THE EXTERNAL CONDENSER CAN BE HOT! If these pipes accidentally can be touched it is recommendable to isolate these pipes. Connect the electrical cable(s) from the CoolMaster to the control switch (S) and fan(s) at the condenser. These cable(s) may not touch the hot gas (P) and the liquid pipes (Q) of the condenser, as these pipes could be very hot! The cable(s) are already connected at the CoolMaster. For the connection of these cable(s), see electrical diagram. Switch on main switch on control panel (G) to enable the crankcase heating of the compressors. At the first start up is not allowed to switch the CoolMaster immediately on by means of the control switch. There must be a delay time of at least 24 hours before the CoolMaster is switched on for the first time by means of the control switch or external start/stop. During this period the sump heater will evaporate the coolant out of the sump oil of the compressor. NOTE! The CoolMaster may not be switched off by means of the main switch, due to the crankcase heating which will be switched off. To prevent serious damage to the CoolMaster, the crankcase heating may never be switched off. When the CoolMaster is to be switched off, it must be done by means of the control switch which is located at the control panel (G). EVEN ON LONG TERMS OF STANDSTILL! WARNING! In case of shutdown with control switch all parts in the control box will still be under tension. If this will result into hazardous situations, in example maintenance to the CoolMaster, the CoolMaster needs to be switched off with the main switch.

Attention! Before making any connections to the CoolMaster, clean the external pipes. Dirt must be prevented from entering the CoolMaster. It may cause serious damage to the system and the CoolMaster. Connect the following pipes: - A and B: cooling water pipes between CoolMaster and the user. - D1: If you wish to fill automatically (does not apply to machinery specified as (N)(NO)(NOF)(O)(OF)). Step 1: 1. Install the ball valve (BVS-1) on the cooling water inlet (A). 2. Install cooling water pipe between CoolMaster (BVS-1) and User. (See Figure 5.3) The ball valve (BVS-1) must be kept closed, unless otherwise indicated! Step 2: 1. Install the ball valve (BVS-2) on the cooling water outlet (B). 2. Install the ball valve (BVS-3) on the T-piece (central section). 3. Install the cooling water pipe between CoolMaster (on the T-piece) and the user. (See Figure 5.4) The ball valves (BVS-2 and BVS-3) must be kept closed, unless otherwise indicated! Step 3: 1. Connect the cooling water pipes between CoolMaster and user (BVS-1 and BVS-3). (See for supplied connecting diagram) 2. Connect D1 to a water tap if you wish to fill automatically. (does not apply to machinery specified as (N)(NO)(NOF)(O)(OF))

Connect the overflow pipe (C+E). To enable good outflow of superfluous water, the overflow pipe must be able to flow out into the open sewer without any foreseeable obstructions. The length of the overflow pipe should be kept to a minimum. The pipe should also flow downwards, from the perspective of the CoolMaster (C+E). CAUTION! For machines filled with a mixture of water and glycol (machines specified as (N)(NO)(NOF)(O) the excess mix from connection E may not be discharged into public sewers for environmental reasons. Connect refrigerant relief (V). This connection is an safety valve which blows off refrigerant in unusual extreme conditions. Because refrigerant results to asphyxiation, the refrigerant relief (V) must be connected to the open air at a position where it is not dangerous! The refrigerant relief between the CoolMaster and the open air should be fixed tightly and must not be longer than 20 meters. The minimum internal diameter must correspond with the diameter of connection on the CoolMaster. (if applicable)

Attention! Work may only be carried out on the electrical installation of the CoolMaster by an authorised, professionally competent person.

Attention! The CoolMaster must only be connected to a clockwise rotary field.

Turn off the main switch on the control panel (G). Connect your electrical power supply cable to the appropriate terminals in the control box via the cable entry (F). Refer to the electro-technical diagram for the connection of the cable cores. Consult the diagram number as stated on the technical specifications sheet corresponding to the serial number of the CoolMaster. Consult the type plate for the correct voltage. Attention! Ensure the voltage as stated on the type plate is also the voltage on each phase wire. Of no less importance is the mains frequency (50 or 60 Hz) corresponding to the frequency on the type plate. The maximum voltage deviation is +6% and –10% from the voltage indicated on the type plate

CAUTION! BEFORE OPENING MACHINE, ALWAYS ENSURE POWER SUPPLY IS COMPLETELY DISCONNECTED!

DTE uses reputable components in its products, whereby DTE will reduce the risk of faults in its machines. This also applies to the water pumps. These pumps are made with a stainless steel fan, a high quality pump house and a “Mechanical seal” to seal the axis. The mechanical seal is a high quality axis seal made from polished hard metal, and all contact surfaces are polished. This will guarantee a good sealing even under the toughest operating circumstances. The mechanical seal will lubricate itself by means of a thin liquid layer of the pumped fluid. When the machine has not been used for a long period there is a chance that the water pump will not run. The cause of this fault may be cohesion between the polished contact surfaces of the mechanical seals. The seals "stick together". This problem is easily solved by rotating the pump axis by hand. In the Grundfos pump, it can be done by first removing the roster by unscrewing the two or four screws. You can now rotate the engine fan by hand. The sticking together has now been broken and the machine can be started. See Figure 5.31 and Figure 5.32) CAUTION! MAKE SURE TO REPLACE THE ROSTER, OTHERWISE THE PUMP ENGINE WILL NOT BE COOLED PROPERLY!

INTRODUCTION Semi-closed and closed cooling systems are used in many processes. An efficient and effective cooling system is needed for a process to function without problems. Generally such cooling systems contain between 0.5 and 5.0 m³ water, which is normally topped up with tap water. The tap water available is often, technically speaking, of poor quality:

• contains limescale and/or

• is corrosive The system may contain many different materials with which the cooling water comes into contact. Such as:

• steel/cast iron

• copper/brass

• aluminium

• synthetics/sealants PROBLEM DEFINITION Corrosion problems can occur in cooling systems, which have different causes. The presence of different materials can result in galvanic corrosion, which is where the least precious metal is dissolved. The action of oxygen on iron and steel causes oxygen corrosion and the formation of iron oxide or silt. Natural silt accumulation can lead to “under deposit corrosion”. High flow-speeds can lead to erosion corrosion. The quality of the cooling water plays a significant role in this. GENERAL MEASURES

Contamination Measure

Mechanical contamination caused by iron oxides or silt Install filters, depending on contamination

High hardness Soften water via ion exchange

Minor contamination caused by presence of oxides and hardness

Use water treatment in the form of hardness stabilisation and corrosion inhibitors

Biological contamination caused by presence of algae and slime bacteria

Use water treatment in the form of biocides

WATER TREATMENT Specific water treatment should be used if one or more values cannot be maintained or achieved. Water treatment products can be used for a wide variety of applications in this case. DTE has a water treatment in the form of PollutionMaster. This product can optionally be supplied. If the temperature of the water exceeds approx. 40°C, (partial) water softening must in general be applied. A complete water treatment proposal can be drawn up after the water quality has been assessed on site. CLEANING If the cooling system is already very contaminated, we recommend cleaning the system with a suitable cleaning product. The cleaning solution can be pumped around using the system pump or an cleaning pump. For the best cleaning result, at least some flow should be established across all components. The cleaning progress can be monitored through visual inspection and using pH test strips. Systems with considerable biological contamination should be rinsed thoroughly first. A bio-dispergator can also be used for this purpose. The cleaning method and costs will be assessed and determined per situation. Note: You can contact DTE anytime.

1144..33 GGuuiiddlliinnee ffoorr wwaatteerr qquuaalliittyy iinn DDTTEE iinnssttaallllaattiioonnss

Water quality for use in all DTE installations is prescribed in this general guideline. Water quality used in DTE

installations should meet this standard at all times.

Standard values for water quality: - Acidity: PH 7 < PH 9,5

- Chloride: < 50mg / L

- Conductivity: 150 µS < 350µS

- Bicarbonate (HCO3): 80mg/L < 100mg/L

- Hardness: 2dH° < 8dH°

This directive is a general directive which also applies to systems in which water with a percentage of glycol is used. In cases where a water-glycol mixture is to be applied, the quality of water must first be analysed to be ensured the water quality is within the norm values. Subsequently, a water-glycol mixture may be prepared that must be tested on mixing ratio before use. In the system the absorption of oxygen must prevented to keep the hydrogen carbonate (HCO3) level within the acceptable range. In case of doubt, this should be tested with a sufficient frequency.
