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 eciency of the unit will be better.
3. Cut o 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 outdoor unit. The only permitted connections
are those for which the units are designed.

Finish wrapping insulating tape around the rest of the pipes leading to the outdoor
unit.
4 The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be xed to the wall with suitable ducts.
5 Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness
according to the pipe size.
Indoor temperature of 30°C and humidity of 85% is the stan dard condition.
If installing in a high humidity condition, use one grade thicker insulator by referring to the table below.
