- The cooling lines between the two units should be in
special copper pipes forcooling installation.

- Check the internal part of the pipes and eventually
remove dirt or dampness as they can interfere with
proper operation.

- The cooling lines should be singularly insulated with
polyurethane foam with closedcells.

- Plan theroute of thepipeline to reduce the length and
the number of bends as much as possible for best
performance of the system.Alwaysuse a pipe folder.

- After having cut the connection pipes, eliminate the
slight defects by maintaining the pipe opening
downward.

- For a correct flange operation, use a flange tool for
pipes and eliminate the eventualdefects.

- Check that the flangesdo not have anydefect.

- Removethe connectionslocated onthe indoorunit. A
little quantity of air will be expelled to show the good

CONDENSE DRAINAGE

The indoor unit is fitted with condense drain pipe
which a drainage hose ( inside 16 mm) should be
connected, leading to a suitable drainage outlet area.
Fasten the condensate drain pipe to the refrigerant
pipes with adhesive tape whenever the lines cross
through a wall; this is to prevent the condensate drain
pipes from being crushed.
The drainage pipe should have a 3-5° inclination
down towards the drain; it should never be inclined
upwards.
Check all the joints for leaks.
The condensate drain pipe should be inserted into the
couplings located on the bottom left or right part of the
indoor unit.

Carefully check the condensed water
outflows from thepipeeasily.

mode, during this operation, the condensed
water may be drained from the outdoor unit.

For this reason it is advisable to check if the
moisture drainage directly on the floor is
acceptable. If not, it is possible to collect the
moisture through a union elbow ( supplied
together with the unit ) connected to a drainage
pipe. In this way the moisture will be
discharged in a specific area.
In case of floor installing, before connecting the
drainage pipe to the union elbow, it is before
necessary to insert below the unit some
spacers to avoid vibrations: the spacers also
allow the necessary space to insert the union
elbow.
