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.
The equipment is not intended for use in a potentially explosive
atmosphere.

C
HECKING THE WATER CIRCUIT
The units are equipped with water inlets and water outlets for connec-
tion 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 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.
