Installation - cables

When the location of the indoor and outdoor units has been
decided and they have been installed, it is time to fit the
refrigerant pipes and electric cables between the indoor unit
and outdoor unit. The lower part of the indoor unit should be
removed completely to facilitate the installation of the indoor
unit (not applicable to 416-086). There are quick couplings on
the four-conductor power cord that can easily be connected
to the indoor unit. Press the connectors together and fit the
cable with the help of a strain reliever.
Never connect power before the pipes have been routed and
the system's modules are interconnected.
Push the wall bushing in from the outside, then push on and
secure the cover ring.

Installation - refrigerant pipes

Start the installation of the pipe kit at the indoor unit and then
straighten out the pipes gradually. On the ends of the pipe
lengths (installation kit)
connections. There are two fixed nipples on the units' pre-
fitted pipe sections. The pipe lengths' loose screw
connections must be screwed to the units' fixed nipples.
These cannot be installed incorrectly, but it is very important
when connecting that the nipple is held in a fixed position,
while the second spanner screws on the coupling.
IMPORTANT:
Note that the pipes in the installation kit are filled with gas and must not be cut under any circumstances.
The plastic plugs on the ends of the pipe must not be removed until the pipes are to be connected. If the
pipes are bent and causing leakage, the couplings must be loosened so that the non-return valves close.

there are two loose
Now connect the pipes from the installation kit with the
fixed nipples on the indoor unit couplings. Start by
threading together all the screw connections by hand. Then
use the spanners to tighten the coupling.
Complete the connection without stopping (a hissing sound
may be heard), use a counterhold and tighten the coupling
securely.
Tightening min. torque 18 Nm. Use a torque wrench when
in doubt.
Never under any circumstances tighten the fixed nipples
with the spanner. Use one of the spanners only as a
counterhold when connecting. It should be noted that if you
do not use a counterhold, you risk turning the nipples on
the indoor unit too much and rendering them useless. The
couplings have to be tightened around 24 h after the
installation has been completed.
