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.
IMPORTANT INFORMATION REGARDING THE
REFRIGERANT USED
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type: R407C
GWP
(1)
value: 1652.5
(1)
GWP = global warming potential
The refrigerant quantity is indicated on the unit name 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.

- It is very important to install the flowswitch as shown in the figure observe the position of the flowswitch in relation to the direction of the water flow if the flowswitch is mounted in an other position the unit is not protected properly against freezing 5
- Onnecting the water circuit 5
- Shut off valves must be installed at the unit so that normal servicing of the water filter can be accomplished without draining the complete system 5
- The water filter must be installed in front of the unit for removing dirt from the water to prevent damage to the unit or blockage of the evaporator or condenser the water filter must be cleaned on a regular base 5
- The flowswitch must be installed in the water outlet pipe of the evaporator to prevent the unit from operating at a water flow which is too low 5
- To assure proper operation of the unit a minimum water volume is required in the system and the water flow through the evaporator must be within the operation range as specified in the table below 5
