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.

Please check the elevation difference between
the indoor unit and the outdoor unit, the length
of the refrigerant pipe, and the curved places
(bend) of the pipe as following:
Elevation difference: no more than 10m/32.8ft
Pipe length: no more than 20m/65.6ft
Bends: no more than 5 places
A minimum pipe run of 3 metres is required to
minimise vibration & excessive noise.
