Vertical Piping Guidelines
Piping runs should be kept as short and compact as possible. Low-
lying areas (oil “traps”) where oil can
accumulate should be avoided. Refer to the following guidelines with regards to the vertical placement
of the evaporator and condensing units:
1.
When the evaporator and condensing unit are located on the same level,
pipe suction line with
inverted trap as shown to prevent liquid migration to the compressor during the off cycle. Pitch the
suction
line
slightly downward
to the condensing unit:
2. When the evaporator is located below the condensing unit,
a suction trap must be installed at
the evaporator, and an inverted trap must be installed at the condensing unit, for proper oil return, as
follows:
