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.
55..33 CCoonnnneeccttiinngg ppoowweerr ssuuppppllyy
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.

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.

CoolMaster (N): Fill the CoolMaster with the mix of water and
glycol (using manual fill D2). (See Figure 5.24)
WARNING! This mixture must be prepared beforehand.
Filling with water first and adding the glycol afterwards or
vice versa is prohibited. For the mixing ratio for this
machine see the appropriate specifications list.
External systems must be filled via an external filling point. See
chapter §5.7 for instructions.
To add any chemicals or other substances, please consult the
supplier.
WARNING! To prevent the heat exchange and/or other
parts from freezing, the mixing ratio of the water and

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 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 5.27 and Figure 5.28)
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.

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.
