Pipe routing
IMPORTANT:
Continue the pipe from the indoor unit to the outdoor
unit and connect the pipe fittings in the same way. The
radius at pipe bends must not be less than 15 cm. Use
a cardboard template to check this. Run the power cord
along with the pipes. Create the bends gradually and
carefully. You must not bend the pipe straight across,
for example, to the edge of the hole in the wall.

Connecting the installation kit

On the ends of the pipe lengths (installation kit) there are two loose screw connections.
There are two fixed nipples on the outdoor unit’s 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 (counterhold), while the second
spanner screws on the coupling.
Connect the pipes from the installation kit with the
fixed pipes mounted on the outdoor unit. Start by
screwing 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.
Never under any circumstances tighten the fixed
nipples with the spanner. Only use the spanner as a
counterhold when connecting. It should be noted that
if you do not use a counterhold, you risk turning the
nipples on the outdoor unit too much and rendering
them useless. Check and tighten the couplings about
12-24h after installation.
There are two types of refrigerant piping connectors, flare nut and quick connector. It
depends on different models.
