Oil equalisation connection The level of oil is naturally balanced by a 1”1/8 oil
equalization line.
The kit 120Zxxxx includes a 1”3/4 to 1”1/8
adaptor sleeve (4) & a teon seal (5) to connect
the oil line to the compressor 1”3/4 oil connector
(8).
The oil line is brazed to the sleeve which is
inserted (depth D=1.97in) into the compressor
and tted using rotolock system.
The organ pipe needs to be installed in
the direction indicated by the label attached,
which will ensure best oil balance.
Suction washer Due to the dierence of capacities of the
compressors, it is essential to equalise the
pressure of the sump. But, this oil equalisation
is also function of the conguration of the
suction pipe. Suction washer is on xed speed
compressors.
