Purging the unit
From factory the unit is supplied and set with a pre-charge of nitrogen gas. (insert gas) Therefore, all insert gas must be
purged before connecting the assembly piping.
Unscrew the pinch pipe at the end of each refrigerant pipe.
RESULT : All inert gas escapes from the indoor unit.

Connecting the refrigerant pipe
There are two refrigerant pipes of different diameters :
A smaller one for the liquid refrigerant
A larger one for the gas refrigerant
The inside of copper pipe must be clean & has no dust
1. Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, rst
manually and then with a torque wrench, a spanner applying the following torque.
2. Must use insulator which is thick enough to cover the refrigerant tube to
protect the condensate water on the outside of pipe falling onto the oor
and the efciency of the unit will be better.
3. Cut off any excess foam insulation.
4. Be sure that there must be no crack or wave on the bended area.
5. It would be necessary to double the insulation thickness(10mm 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

NOTE
• To prevent dirt or foreign objects from getting into the pipes during
installation, do NOT remove the pinch pipe completely until you are
ready to connect the piping.
NOTE
• If the pipes must be shortened refer to page 23.
CAUTION
• Connect the indoor and outdoor units using pipes with ared 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.
outdoor unit. The only permitted connections are those for which the units are designed.
