8. Route the electrical cable along the pipes.
9. Leakage test the refrigerant pipe connections by using a
leakage spray or electronic leakage detector.
Connection of water pipes
NOTE:
•
Fully insulate the hot water pipe.
• Do not cover the valves with insulation, they must be
accessible for maintenance.
• Check that the water pressure is sufficient. If there is not
enough water pressure, install a pressure control pump to
increase the pressure.
1. Connect the inlet and outlet water pipes in accordance with
local regulations.
2. Use suitable water pipes and handle with care.
3. Clean and pressure test after connecting.

Filling with water
1. Fit the check valve on the water inlet to prevent return flow
when the water supply is disconnected or if there is low
water pressure.
2. Fit filters (20 meshes/cm²) on the inlets to the water tank
and indoor unit water to provide protection from sediment
and guarantee the quality of the water.
3. A shut-off valve should be fitted to simplify draining and
cleaning of the filter.
Draining the water
1. Unscrew the three screws at the top of the front panel.
2. Lift the front panel 10–15 mm, loosen the quick connector
from the wired control unit and remove the front panel.
3. Pull out the hose and shut-off valve connected to the water
tank.
4. Lead the hose in a suitable drain and open the tap to empty
the tank. Connect the drainage hose to another hose if
necessary to reach the drain.

PIPE AND CABLE ROUTING
NOTE:
•
The drainage hose is only used for air/air-heat pumps,
not for air/water-heat pumps.
• Do not remove the plastic plugs from the pipe ends before
commencing installation.
The installation kit comprises 2 gas-filled pipes, drainage hose,
sealing compound, polyethylene tape, 2 insulation sections, cable
ties and electrical cable with connections for the indoor and the
outdoor unit.
Connection of refrigerant pipes
WARNING!
•
The pipes in the installation kit are filled with gas and
must not be cut under any circumstances.
• Refrigerant pipes must not be bent to a radius of less than
15 cm. Bend the pipes carefully, little by little. Do not bend
the pipes too sharply.
FIG. 12
NOTE:
If the pipes are twisted and cause leakage, release the cap nuts
from the connections so that the check valves close.
1. Start routing the pipes from the indoor unit.
2. Bend the pipes so that the connections align with each
other. Finish one connection before the next one is started.
3. Connect the pipes in the installation kit to the connections
on the indoor unit. Screw the screw connections by hand
first, and then tighten with the spanners.

4. Tighten the connection fully without stopping. A hissing
noise can be heard.
5. Brace the connection with a screwdriver and tighten the cap
nut with another. Tighten to at least 18 Nm. Use a torque
wrench when in doubt.
– Never turn the fixed connections. Use the spanner only
as a counterhold during connection.
– If a counterhold is not used, the connections can turn,
which can destroy them.
6. Tighten the connections 24 hours after installation has been
completed.
7. Route the pipes from the indoor unit to the outdoor unit and
connect them in the same way to the outdoor unit. On the
pipe ends in the installation kit are cap nuts for connection
to the fixed pipe sections on the outdoor unit.
