CAUTION
• Oil traps
If the indoor unit is installed higher than the
outdoor unit:
-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 10m
of vertical suction line riser.
The indoor unit is installed higher than the
outdoor unit
CAUTION
If the outdoor unit is installed higher than the
indoor unit:
-It is recommended that vertical suction risers
not be upsized. Proper oil return to the
compressor should be maintained with suction
gas velocity. If velocities drop below 7.62m/s,
oil return will be decreased.
An oil trap should be installed every 6m of
vertical suction line riser.
The outdoor unit is installed higher than the
