3. Connect the sensor cable T6 on the indoor unit to the 12
m extension cable. Connect the other end of the extension
cable to the outside temperature sensor T6.
FIG. 25
4. Put the outside temperature sensor T6 in the plastic fastener.
5. Drill a hole in the outer wall and fit the plastic fastener with
the sensor on the wall with a screw.
FIG. 26
6. Fit the plastic cover over the sensor.

OUTDOOR UNIT
FIG. 28
• The outdoor unit has 2 wall brackets, 4 vibration dampers,
and mounting screws for masonry/concrete walls.
• The outdoor unit's pipe sections are pre-filled with
refrigerant and fitted out with screw connections with
non-return valves.
Hole-making
NOTE:
Work at low speed to avoid overheating.
1. Predrill the hole first to check that the area is free from
obstructions and to get the hole in the right position.
– Predrill with a 12–15 mm drill, so that it is easier to
remove residual material from the hole.
– Move the pilot drill carefully inside the wall to check
whether there are any obstructions near the hole.
FIG. 29
2. If there are no obstructions, fit the wall bracket and make
the inlet hole (approx. 80 mm, depending on the enclosed
wall bushing) with a hole saw.
FIG. 30
Installation
NOTE:
Check that the outdoor unit is horizontal. It is very important
that the outdoor unit does not lean forward too much, or to the
right. Adjust with spacers, if necessary.
• The enclosed brackets are intended for installation on brick
or concrete walls.
• When installing on a wooden wall, suitable reinforcement
and mountings must be used.
• A ground stand is recommended instead of installation on a
wooden wall.
• Fit the brackets with a c/c distance of 505 mm, at least
50 cm above the ground.
• In snowy areas the unit should be placed higher up,
to ensure good air circulation and drainage.
• Install vibration dampers between the unit and the wall
brackets. Do not overtighten the nuts and compress the
rubber, this will reduce the vibration damping.
• Leave at least 10 cm of free space around the outdoor unit
and the wall to ensure adequate ventilation.

PIPE AND CABLE ROUTING
WARNING!
Never connect the heat pump to the mains before the piping
is installed and the system modules have been connected
together.
NOTE:
• Bend the pipes carefully, little by little. Do not bend the
pipes too sharply. Refrigerant pipes must not be bent to a
radius of less than 15 cm.
FIG. 35
• Route the electrical cable along the pipes.
• The pipes in the installation kit are filled with gas and
must not be cut under any circumstances.
• Do not remove the plastic plugs on the pipe ends until just
before connecting the pipes.
• If the pipes are warped and leak, release the female
connectors from the connections so that the check valves
close.
• Check the connections for leakage by using soapy water
and looking for bubbles. Repeat the leakage check with
soapy water after 24 hours.
FIG. 36
• When the indoor and outdoor units have been installed,
connect the electrical and refrigerant circuits.
• Remove the bottom part of the indoor unit to simplify
routing the piping and cable.
• The cable (4-wire) has a plug for easy connection of the
indoor unit. Plug in the plug and fasten the cable in the
holder.
• Press the wall bushing into the hole from the outside,
then press on and lock the seal.
FIG. 37
Connect the installation kit to the indoor unit.
NOTE:
• Start routing and aligning the pipes from the indoor unit.
• The pipe ends in the installation kit have female
connectors for connection to the fixed pipe sections on the
units.
