UNPACKING AND PLACING THE UNIT
1 Remove the wooden crate from the unit.
2 Remove the screws fixing the unit to the pallet.
3 The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete).
4 Fasten the unit in place using four anchor bolts M12.
5 Make sure that the unit is levelled in both directions.
6 If the unit is operating below –5°C ambient, the unit must be
installed out of the wind. If this is not possible, a windscreen
must be installed.

CHECKING THE WATER CIRCUIT
The units are equipped with a water inlet and water outlet for
connection to a water circuit. This circuit 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:
Only for EUWYN version
■ A circulation pump must be provided in such a way that it
discharges the water directly into the water heat exchanger.
■ Provide adequate safeguards in the water circuit to make sure
that the water pressure will never exceed the maximum
allowable working pressure (10 bar).
For all versions
■ A kit containing 2 ball valves and 1 filter is delivered with the
unit. For location of the kit within the unit, refer to the outlook
diagram and to the sticker on the frontplate of the unit. Install this
kit at the water inlet of the unit. Refer to figure 3.
■ 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. A drain plug is provided to drain the water
from the chiller water system.
■ Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible for
servicing. An automatic air purge is provided on the chiller water
system.
■ Take care that the components installed in the field piping can
withstand at least the sum of opening pressure of the safety
valve + the static height of the pump.
■ For EUWYP and EUWYB: 6 bar.
■ For EUWYN: depending on the selected pump and safety
valve.
CONNECTING THE WATER CIRCUIT
Water connections must be made in accordance with the outlook
diagram delivered with the unit, respecting the water in- and outlet.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
1 Use clean pipes only.
2 Hold the pipe end downwards when removing burrs.
3 Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
4 Use a good thread sealant for the sealing of the connections.
The sealing must be able to withstand the pressures and
temperatures of the system, it must also be resistant to the used
glycol in the water.
5 Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes. Refer to figure 3.
1 Prepare a water drainage channel around the
foundation to drain waste water from around the
unit.
2 If the unit is to be installed on a roof, check the
strength of the roof and its drainage facilities first.
3 If the unit is to be installed on a frame, install a
waterproofing board with a distance of 150 mm
under the unit in order to prevent infiltration of
water coming from under the unit.
4 In case of indoor installation, make sure to
connect a drainhose to the drain connection
(Ø16).
Not installing the filter kit can lead to severe damage
of the unit.
Be careful not to deform the unit piping by using excessive
force when connecting the piping. Deformation of the
piping can cause the unit to malfunction.
