5.4 Assembly
Place the cooling unit at the intended position and secure against shifting.
For unit-specific connections, see Chap. 13.1 Technical data
5.4.1 Electrical connection
Note
Make sure that the electrical feed is shut off throughout the assembly period.
Connect the power feed cable (terminal X1)
Connect the communication cable (terminal X3).
5.4.2 Connecting the remote control
The cooling unit is prepared for connection of a remote control with potential-free group alarm,
ON-OFF and enable (see electrical diagram).
5.4.3 Connections of the medium circuit
Connect the water hoses in accordance with the labelling on the cooling unit
(inlet/outlet) and secure with hose clips.
The line nominal widths for the external medium circuit must be determined based on the
available pump pressure and the expected loss in pressure in the consumer circuit. The medium
lines can be implemented with a fixed or flexible design.
Ensure material compatibility throughout the entire medium circuit. The following materials can
be installed in the water circuit in the cooling unit:
– Copper
– Stainless steel
– Brass
– Plastic
– Nitrile elastomer
Depending on the materials used in the external water circuit, (outside of the unit, customer-
provided installation), material incompatibilities can cause corrosion damage.
Pay particular attention in this regard if using galvanised and aluminium materials.
If in doubt, consult qualified specialist companies.
When connecting the medium circuit, avoid contamination in the external line system
(rinse the lines prior to connecting).
