Installation on final installation position
■
Place the unit in the appropriate installation location.
■
Level the unit to a stable position
using the levelling feet.
■
Push the sound strips against the ground and fix the side plates
with the appropriate screws.
■
Close the sound panel(s) and decoration panel(s) which will be
on the wall side and for which fixation is not possible anymore
after the unit is put on its final location.
Connecting the water circuit
Water connections must be made. The connected flexible pipes need
to be connected to the piping that leads to the heat emitters as
follows:
1 Field piping
2 To heat emitters
If air or dust gets in the water circuit, problems may occur. Therefore,
always take into account the following when connecting the water
circuit:
■
Use clean pipes only.
■
Hold the pipe end downwards when removing burrs.
■
Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
■
Use a good thread sealant for the sealing of the connections.
■
When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
■
Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
CAUTION
The weight of the unit is approximately 116 kg. At
least two persons are required to lift the unit.
Use the plates delivered with the unit (accessory bag)
to lift the unit.

INFORMATION
Standard installation location of the optional domestic
hot water tank is on top of the indoor unit.
If available service space to left and/or right side is
limited, carefully consider all tank module installation
steps first.

NOTICE
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.
NOTICE
■
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.
■
Never use Zn-coated parts in the water circuit.
Excessive corrosion of these parts may occur as
copper piping is used in the unit's internal water
circuit.
INFORMATION
When using a 3-way valve or a 2-way valve in the water
circuit, the maximum changeover time of the valve shall be
less than 60 seconds.
