S
ELECTION
OF
LOCATION
The units are designed for indoor installation and should be installed
in a location that meets the following requirements:
1
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2
The space around the unit is adequate for servicing.
3
There is no danger of fire due to leakage of inflammable gas.
4
Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone.
5
Ensure that water cannot cause any damage to the location in
case it drips out of the unit.

HECKING
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.
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 dis-
charges 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
Vibration eliminators 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.
