SELECTION 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.
INSPECTING AND HANDLING THE UNIT
At delivery, the unit should be checked and any damage should be
reported immediately to the carrier claims agent.
UNPACKING AND PLACING THE UNIT
1 Cut the straps and remove the cardboard box from the unit.
2 Cut the straps and remove the cardboard boxes with waterpiping
from the pallet.
3 Remove the four screws fixing the unit to the pallet.
4 Level the unit in both directions.
5 Use four anchor bolts with M8 thread to fix the unit in concrete
(directly or using the floor standing supports).
6 Remove the service front plate.

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.
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.
