Always observe the following safety instructions and warnings!
WARNING!
Warning of possible damage to the device, environment or user
WARNING!
Warning of electricity and / or current threat
WARNING!
Warning of possible entrapment hazard
Compliance with the technical manual is a prerequisite for fault-free operation and the honouring of any
warranty claims. Therefore please read the technical manual carefully before you start working with your
device! The manual must therefore be kept near the machine. The CoolMaster is under pressure with a
refrigerant, more information about this can be found in Appendix 14.6.
This user’s manual was written for types similar to DTE CoolMaster (K), (N) type machines. Therefore
certain topics may not apply to your machine. For the same reason, the images may differ slightly from
how your machine actually looks. When deviating from the standard, a machine drawing is included as
an attachment.

valve. (See Figure 3.1) Further draining of the Water tank with a wet
vacuum cleaner. (See Figure 3.2)
Step 3: Drain the Tempering/Hot water tank by opening the
drainage/overflow valve. (See Figure 3.3)
Step 4: If present, switch on all solenoid valve by external power.

Before packing, transport and storage, first follow the instructions of chapter 3.1.1 Draining water
from the machine.
Attention! Before transport the machine has to be protected with the also delivered cardboard
box or has to be wrapped with bubble wrap. The machine has to be transported and stored
perpendicular at all time on its fundament on the provided pallet!
The machine has to be placed perpendicular on its fundament at all time.
Attention! In no way the machine can be stacked or overturned. This during transport and storing
as well during repairs and commissioning. Even when the machine is not used it should be
perpendicular at all times.
Attention! Not following these instruction can cause big damage to the machine.
Use at all time the right equipment such as a pallet truck and a forklift truck.

See for the connections chapter 4.
CAUTION! The installation work must be carried out by a certified professional!
Place the CoolMaster at a level position and at least 1 meter from a wall. For a good functioning of the
CoolMaster we recommend keeping the distance between the CoolMaster and the user to a minimum.
The cooling water pipes between the CoolMaster and the user must be longer than 15 meters.
WARNING! The diameter of the pipes/hoses must at least match with the connections on the
CoolMaster.
The hoses MUST be reinforced with braided fibre to prevent kinking the hose.

Let op! 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))
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 5.1)
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 5.2)
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 appendix §14.2
2. Connect D1 to a water tap if you wish to fill
automatically.

Connect the overflow pipe (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 (E).
CAUTION! For machines filled with a mixture of water and glycol (machines displaying (N)), the
excess mixture from connection (E) must not be discharged into public sewers for reasons
relating to environmental law.

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! The CoolMaster is not suitable for use with demineralized water or water containing
high levels of minerals or iron.
The filling water which is used must be of good quality. It must at least be of drinking water quality and
the water must not contain high levels of lime and/or iron, as it may cause serious damage.
You must check the water regularly.
The minimum filling pressure must be 2,5 bar.
See Appendix 14.3 for extra information.
See Appendix 14.4 for directive water quality.
CAUTION! The CoolMaster (N) are only suitable for tap water of drinking water quality mixed with
the correct ratio of a suitable anti-freeze (glycol).

3. Connecting the filling water (min. 2.5 Bar) to BVS-3.
4. Turn the valve (BVS-3) to “open”. (See Figure 5.6)
Step 2:
Excess air will be released from the pipe(s) though the air
release valve(s).
If the water spills from the air release valve(s), the external
pipes/systems are filled with water.
1. Turn the ball valve (BVS-3) to “closed”. (See Figure 5.7)
2. Turn the air release valve(s) in your system to the
"closed" position.
3. Turn the water fill line to “closed”.
4. Remove the fill water line which is mounted on BVS-3.
Step 3:
1. Turn the ball valve (BVS-1) to “open”. (See Figure 5.8)
2. Turn the ball valve (BVS-2) to “open”. (See Figure 5.9)
When these steps have been completed correctly, the entire
system will be filled with water.

Step 4:
Excess air will be released from the pipe(s) though the air
release valve(s).
If the water and glycol mixture spills from the air release
valve(s), the external pipes/systems are filled with the water
and glycol mix.
1. Turn the ball valve (BVS-3) to “closed” (See Figure 5.18)
2. Turn the air release valve(s) in your system to the
"closed" position.
3. Turn the ball valve (BVS-5) to “closed”:
4. Remove the ball valve (BVS-5) (See Figure 5.19)
Step 5:
1. Turn the ball valve (BVS-1) to “open” (See Figure 5.20)
2. Turn the ball valve (BVS-2) to “open” (See Figure 5.21)
When these steps have been completed correctly, the entire
system will be filled with the water and glycol mixture.
