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.

Oil traps
CAUTION
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).
