Outdoor Unit BELOW Indoor Unit
Mounting the indoor unit above the
outdoor unit will require an inverted loop
in the suction line adjacent or near the
connection to the indoor unit.
The top of the loop must be slightly higher
than the top of the unit. The trap can prevent
liquid compression of the compressor for
start- up period.
