Refrigerant Piping Connection
When connecting refrigerant piping, do not let substances or gases other than the speci ed
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.
Note on Pipe Length
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 following table :

CAUTION
Oil traps
If oil flows back into the outdoor unit's
compressor, 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).
