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.

Installation Procedure
English
• You must keep the cable in a protection tube.
• Keep distances of 50mm or more between power
cable and communication cable.
• Maximum length of power cables are decided within
10% of power drop. If it exceeds, you must consider
another power supplying method.
• The circuit breaker(ELCB or MCCB+ELB) should be
considered more capacity if many indoor units are
connected from one breaker.
• Use round pressure terminal for connections to the
power terminal block.
• For wiring, use the designated power cable and
connect it firmly, then secure to prevent out-side
pressure being exerted on the terminal board.
• Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
• Over-tightening the terminal screws may break them.
• See the table below for tightening torque for the
terminal screws.
