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
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.
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
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.
Minimum flow rate
NOTICE
If glycol was added to the water circuit, and the
temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the
minimum flow rate can be checked by way of the pump
test (check that the user interface does NOT display error
7H).
There is no minimum required flow rate.

Connecting the brine piping
4.2.1
To connect the brine piping
a b
a
Brine OUT (Ø28 mm)
b
Brine IN (Ø28 mm)
NOTICE
To facilitate service and maintenance, it is recommended
to install shut-off valves as close as possible to the inlet
and outlet of the unit.
