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.
