Installing The Refrigerant Pipes - Jula Anslut 417-030 Operating Instructions Manual

Installing the refrigerant pipes

Start the installation of the pipe kit at the indoor
unit and then straighten out the pipes successively.
First bend the pipe from the indoor unit in the
direction of the outdoor unit. The drainage hose
should lie in the bottom of the hole. Start the bend
for the pipe inside the hole, so that there is a
smooth bend to the outer wall. It is very important
not to bend the pipe to the edge of the hole, this
can cause a wrinkle in the pipe which can prevent
the through flow of the refrigerant. Repair any
wrinkles in the pipe before connecting the
installation kit.
There are protective caps on the pipe ends, which
must be screwed off before fitting. It is very
important to keep the coupling completely clean
and free from moisture. On the ends of the pipe
lengths (installation kit) there are two loose screw
couplings. There are two fixed nipples on the pre-
fitted pipe sections on the units. The loose screw
couplings on the pipe lengths must be screwed to
the fixed nipples on the units. 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.
Now connect the pipes from the installation kit with
the fixed nipples on the indoor unit couplings. Start
by screwing together all the screw couplings by
hand. Use the spanners to tighten 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 cause leakage, the couplings must be loosened so that the non-return valves close.
ENGLISH
Complete the connection without stopping (a
hissing sound may be heard), and use a
counterhold to properly tighten the coupling.
Minimum tightening torque 18 Nm. Use a torque
wrench when in doubt.
Never under any circumstances tighten the fixed
nipples with the spanner, only use one of the
spanners as a counterhold when connecting. Note
also that without a counterhold there is a risk of
turning the indoor unit nipples too much so that
they break. The couplings must be retightened
about 24 hours after the installation.
