Refrigerant Piping Connection
When connecting refrigerant piping, DO NOT let substances or gases other than the specified refrigerant enter
the unit. The presence of other gases or substances will lower the unit' s capacity, and can cause abnormally high
pressure in the refrigeration cycle. This can cause explosion and injury.

Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between the indoor and outdoor
units meets the requirements shown in the table next to it:
CAUTION
Mark the data plate with the Orifice installed.
•
Please purchase the fittings according to the requirements in the manual strictly.
•
Refer the diagram when installing.

CAUTION
Oil traps
If oil flows back into the outdoor
this might cause liquid compression or
deterioration of oil return. Oil traps in the rising gas
piping can prevent this.
An oil trap should be installed every 6m (20ft) of
vertical suction line riser (36000Btu/h unit). An
oil trap should be installed every 10m (32.8ft) of
vertical suction line riser (≥36000Btu/h unit).
