Mounting the indoor unit
3.3.1
To install the indoor unit
1
Lift the indoor unit from the pallet and place it on the floor. See
"2.1.2 To handle the indoor unit"
5].
2
Connect the drain hose to the drain. See
10].
3
Slide the unit into position.
4
Adjust the height of the 4 levelling feet of the outer frame to
compensate for floor irregularities. The maximum allowed
deviation is 1°.
≤1°
NOTICE
Do NOT tilt the unit forwards:
0°
1° 1°
NOTICE
To avoid structural damage on unit, ONLY move the unit
when levelling feet are at their lowest position.
NOTICE
For optimum sound reduction, carefully check if there is no
gap between the bottom frame and the floor.
3.3.2
To connect the drain hose to the drain
Condensate can form inside the unit during cooling operation or with
low brine temperatures. The top and backup heater drain pans are
connected to a drain hose inside the unit. You must connect the
drain hose to an appropriate drain according to the applicable
legislation. The drain hose is routed through the rear panel, towards
the right side of the unit.

Piping installation
4.1
Preparing piping
WARNING
It is the responsibility of the installer to ensure the
compatibility of field piping with the used anti-freeze fluid in
the brine circuit. Do NOT use Zn-coated piping, as this
may lead to excessive corrosion. See also
11].
NOTICE
In case of plastic pipes, make sure they are fully oxygen
diffusion tight according to DIN 4726. The diffusion of
oxygen into the piping can lead to excessive corrosion.
NOTICE
All piping MUST be installed according to section G3 of the
Building Regulations.
4.1.1
To check the water volume and flow rate
of the space heating circuit and brine
circuit
Minimum water volume
Check that the total water volume per circuit in the installation is
minimum 20 litre, the internal water volume of the indoor unit NOT
included.
INFORMATION
If a minimum heating load of 1 kW can be guaranteed and
setting [4.B]
Space
heating/cooling
>
Overshoot
(overview field setting [9‑04]) is 4°C, the minimum water
volume can be lowered to 10 litre.
INFORMATION
In critical processes, or in rooms with a high heat load,
extra water might be required.
NOTICE
When circulation in each space heating/cooling loop is
controlled by remotely controlled valves, it is important that
the minimum water volume is guaranteed, even if all of the
valves are closed.

Connecting the brine piping
4.2.1
To connect the brine piping
NOTICE
Do NOT use excessive force when connecting the field
piping and make sure the piping is aligned properly.
Deformation of the piping can cause malfunctioning of the
unit.
