8. CHECKING THE WATER CIRCUIT
The units are equipped with water inlets and water outlets for connection to a chilled water circuit and to a hot water
circuit. These circuits must be provided by a licensed technician and must comply with all relevant European and
national regulations.
The unit is only to be used in a closed water system. Application in an open water circuit can lead
to excessive corrosion of the water piping.
Before continuing the installation of the unit, check the following points:
▪
Additional components not delivered with the unit
1.
A circulation pump must be provided in such a way that it discharges the water directly into
the heat exchanger.
2.
Drain taps must be provided at all low points of the system to permit complete drainage of the
circuit during maintenance or in case of shut down.
3.
Anti-vibration systems in all water piping connected to the chiller are recommended to avoid straining
the piping and transmitting vibration and noise.
▪
Additional water piping delivered with the unit
All additional water piping must be installed on the system according to the piping diagram as mentioned in the
operation manual. The flowswitch must be connected as described on the wiring diagram. See also chapter "Before
starting".
