Check after installation

Have gas leaks been checked?
The termal insulation of the unit is sufficient?
Does the power supply comply with what is
described in the technical label sepcifications.
Le linee di alimentazione e le tubazioni sono
installate correttamente?
Has the earthing carried out correctly?
Are the lines in compliance with the requirements?
Are the obstacles near the air inlet or outlet of the
outdoor and indoor units?
Has the lenght of the pipes and the charge of the
refrigerant been memorized?

Connecting the pipes

5. Standard lenghts of connection pipes: 5m, 7,5m, 8m.
6. The minimum lenght of the connecting pipes is 3m.
7. Maximum lenght and hight difference of the connecting pipes.

If the connection pipes are extended by 10 m but starting from the standard size, add 5 ml
of refrigerant oil for every 5 additional pipe length.
The method for calculating the quantity of refrigerant to be added is the follower:
ADDITIONAL REFRIGERANT CHARGE = ADDITIONAL LENGTH OF TUBE X ADDITIONAL
REFRIGERANT CHARGE
Based on the standard length of the pipes, follow the table below to add refrigerant . The
addition of coolant per meter in length varies according to the diameter of the liquid tube.
