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
connecting the indoor and outdoor units. 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
4.2 MPa and for a burst pressure of at least 20.7
Mpa. 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.
• If the pipes require brazing, make sure that oxygen
free nitrogen (OFN) is flowing through the system.
• Nitrogen blowing pressure range is 0.02 to 0.05 MPa.
Step 8 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 pressurising system
with nitrogen.

• The auxiliary circuit breaker (ELCB, MCCB, ELB) should
be considered more capacity if many indoor units are
connected from one breaker.
• Connect F3, F4(for communication) to the
communication cable of the wired remote control.
• Tighten the electric wires with a proper tool within
the torque limit to connect and fix them firmly, and
then organize the wires to prevent outside pressure
being exerted on the covers and other parts. Failure
to do so may result in overheating, electric shock, and
fire.
Tightening torque (N•m)
M3.5 0.8 to 1.2
M4 1.2 to 1.8
• To protect the product from water and possible shock,
you should keep the power and the communication
cables of the indoor and outdoor units in the iron
pipe.
• Connect the power cable to the auxiliary circuit
breaker (ELCB, MCCB, ELB).
• Keep distances of 50mm or more between power
cable and communication cables.
• Power supply cords of parts of appliances for
outdoor use shall not be lighter than polychloroprene
sheathed flexible cord. (Code designation IEC:60245
IEC 57 / CENELEC: H05RN-F or IEC:60245 IEC 66 /
