INSTALLATION OF COMPRESSOR'S DISCHARGE OIL TRAP BETWEEN INTERNAL AND EX-
TERNAL UNIT
COMPRESSOR'S DISCHARGE
OIL TRAP
ATTENTION
In split installations if the difference in height between the indoor unit and the outdoor unit should be <4m, then the
installation of an appropriately sized oil trap is recommended to stop the oil flow from the compressor going back to
the condenser, as well as the return of the same to the compressor during the OFF phases. If the difference in height
between the units should instead be> 4m, then it is recommended to install a trap every 4m of elevation.
