2 Be sure to use an insulator thick enough to cover the

refrigerant tube to protect the condensate water on
the outside of the pipe falling onto the floor and to
improve the efficiency of the unit.

3 Cut off any excess foam insulation.
4 Make sure that there are no cracks or waves on the

bent area.

5 It would be necessary to double the insulation

thickness (10 mm or more) to prevent condensation
even on the insulator when if the installed area is
warm and humid.

6 Do not use joints or extensions for the pipes that

connect the indoor and outdoor unit. The only
permitted connections are those for which the units
are designed.

CAUTION

• Connect the indoor and outdoor units using pipes
with flared connections (not supplied). For the lines,
use insulated, unwelded, degreased and deoxidized
copper pipe (Cu DHP type to ISO 1337 or UNI
EN 12735-1), suitable for operating pressures of
at least 4200kPa and for a burst pressure of at
least 20700kPa. Copper pipe for hydro-sanitary
applications is completely unsuitable.

• For sizing and limits (height difference, line length,
max. bends, refrigerant charge, etc.) see the outdoor
unit installation manual.

• All refrigerant connection must be accessible, in order
to permit either unit maintenance or removing it

completely.

Step 6 Cutting or flaring the pipes

1 Make sure that you prepared the required tools.

(pipe cutter, reamer, flaring tool and pipe holder)

2 If you want to shorten the pipe, cut it using a pipe

cutter ensuring that the cut edge remains at 90° with
the side of the pipe. There are some examples of
correctly and incorrectly cut edges below.

CAUTION

In case of needing brazing, you must work with nitrogen
gas blowing.

Step 7 Performing the gas leak test

To identify potential gas leaks on the indoor unit, inspect
the connection area of each refrigerant pipe using a leak
detector for R-410A.

Before recreating the vacuum and recirculating the
refrigerant gas, pressurize the whole system with
nitrogen (using a cylinder with a pressure reducer) at a
pressure above 4 MPa in order to immediately detect
leaks on the refrigerant fittings.

Made vacuum for 15 minutes and pressurizing system
with nitrogen.

CAUTION

• If the pipes require brazing ensure that OFN (Oxygen
Free Nitrogen) is flowing through the system.

Step 8 Insulating the refrigerant
pipes

Once you have checked that there are no leaks in the
system, you can insulate the piping and hose.

1 To avoid condensation problems, place Acrylonitrile

Butadien Rubber separately around each refrigerant pipe.

No gap

NBR

NOTE

• Always make the seam of pipes face upwards.

CAUTION

• The insulation has to be produced in full compliance
of European regulation reg. EEC / EU 2037/ 2000
that requires the use of sheaths insulation form
without using CFC and HCFC gases for health and the
environment.

2 Wind insulating tape around the pipes and drain hose

avoiding compressing the insulation too much.
