4. INSTALLATION
The safety notices contained in Chapter 1 must be complied with !
At storage temperatures < 10 °C allow for an appropriate acclimatisation period before
turning the unit on (formation of condensation water) !
Remove transport packaging !
With regard to the required room volume for the installation of the process cooler, the
requirements as per Chapter 1.5.1 (Installation) must be complied with.
The process cooler must be installed in a freeze-proof room on a level, horizontal surface
capable of supporting the weight of the unit.
Any attachments to the floor, intermediate spacers or antivibration mounts are not required.
The process cooler and the equipment to be cooled must always be installed at the same
level.
For different installation conditions, consult the manufacturer.
To ensure trouble-free operation of the process cooler as well as to provide adequate access for
the performance of maintenance and repair work, the minimum clearances – as shown on the
diagram – must be met during installation.
(See also Dimensions)
These installation requirements ensure that the cooling air can be drawn in and discharged
without obstructions; it can thus be largely prevented that the hot air discharged in upward
direction is reintroduced into the process cooler (air short-circuiting).
Moreover, an adequate air flow for carrying off the heat at the installation site must be ensured.

5. MOUNTING
The safety notices contained in Chapter 1 must be complied with !
5.1 Connection of Water Piping
The nominal widths of the pipes for the external water circuit must be selected on the basis of
the available pump pressure and the expected pressure drop in the circuit of the equipment to
be cooled.
The water pipes can be of the rigid or flexible type. The materials used in the equipment to be
cooled must be chemically compatible with the water in order to prevent any corrosion
damage. (See also Chapter Commissioning)
When the piping system is installed by the customer at the installation site, care must
be taken that the pipe system is free from contamination (lines may have to be
flushed prior to connecting the process cooler).
5.2 Electro-Technical Connection
Activities to be performed:
- Establish electrotechnical connection as shown in
the circuit diagram (see appendix)

6. COMMISSIONING
The safety notices contained in Chapter 1 must be complied with !
At storage temperatures <0°C allow for a sufficient acclimatisation period before
turning on the unit (formation of condensation water). The process cooler is designed
exclusively for the cooling of water. Only water complying with the specification may
be used for filling the water circuits !
6.1 Water Circuit
7.1.1 Water Requirements
Only water of drinking water quality may be used.
Water quality:
- Electric conductivity: < 2500 µS at 20 °C
- Hydrogen concentrate: 7 ... 9 (pH-value) at 20 °C
- Chloride: < 250 mg/l
- Total hardness: < 30 °dH
- Colony count: < 100 ml at 22 °C
The following materials may be installed in the water circuit:
- Copper
- Stainless steel
- Brass
- Cast iron
- Plastic
Depending on the materials used in the cooler-remote water circuit (installation provided by the
customer), material incompatibilities could result in a corrosion hazard.
This must be specially taken into account where galvanised and aluminium materials are used.
When in doubt, consult competent specialist companies.
A water filter may have to be installed if there is a hazard of water contamination
during operation (see also Options).
