3 Safety instructions and warnings
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 14.5.
This user’s manual was written for types similar to DTE CoolMaster (K), (N), (NF), (NO), (NOF), (L),
(O), (OF), 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. The machine drawing is
sent separately as an attachment with the correct dimensions and connections.

3.1 Water draining, packing, transport and storage instructions of DTE installations
These actions are general and have to been carried out, of course, if applicable for the
application by qualified personal!
3.1.1 Draining water from the machine
Step 1: Switch the main switch off.
Step 2: Close the filling connection (D1) (not present in machines, specified as CoolMaster
(N)(NO)(NOF)(O)(OF))
Step 3: Drain the Water tank of the cooling system by opening the ball valve.
Step 4: Dry clean all connections and water tank with a vacuum cleaner.
3.1.2 Packing, transport and storage instructions
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 delivered cardboard box or
has to be wrapped with bubble wrap. The machine has to be transported and stored vertically at
all times on its fundament on the provided pallet!
The machine has to be placed vertically on its fundament at all times.
Attention! In no way the machine can be stacked or overturned. This applies during transport
and storing as well during repairs and commissioning. Even when the machine is not used it
should be vertically at all times.
Attention! Not following these instruction can cause severe damage to the machine.
Always use the correct type of transportation equipment, such as a pallet truck and a forklift
truck.

3.2 Correct applications
The CoolMaster (K)(N)(NF)(L)(O)(OF) may only be kept inside a cool, well-ventilated, frost-free
building!
The CoolMaster (NO) is applicable for outdoor installation with ambient temperature until - 15°C by
preference under shelter.
The CoolMaster (NOF) is applicable for outdoor installation with ambient temperature until - 30°C by
preference under shelter.
The CoolMaster (K) is only suitable for tap water of drinking quality.
The CoolMaster (N)(NF)(OF)(NO)(NOF) is only suitable for tap water of drinking quality, mixing with
appropriate antifreeze (glycol) in suitable mixing ratio.
The CoolMaster (L) with external condenser is only suitable for tap water of drinking quality.
The CoolMaster (O)(OF) with external condenser is only suitable for water/glycol.
Information on the correct water-glycol ratio and the recommended type of glycol can be found on the
P&ID corresponding to the machine.
ATTENTION! The CoolMaster must always have at least 3 metres free airflow above it. With an
external condenser, this also applies to the condenser.
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.
3.3 Application area
CAUTION! Application is prohibited:
- In explosive atmospheres.
- In environments with hazardous oils, acids, gases, fumes, substances, radiation, etc.
- Corrosive environment.
