Non-Compressorized Liquid and Suction
Line Piping
There are two different locations to pipe out
of the unit, the post corner hole location and
the post back hole location. The post corner
hole location is to run pipe along the roof and
then down by the disconnect switch
(Figure 20 and Figure 22). The post back hole
location is to run the pipe along the roof, back
across the coil, and come out near the blower
access panel (Figure 21 and Figure 23).
When drilling the holes, use a 3.2 cm (1 ¼”)
inch hole for the suction line and a 1 inch hole
for the liquid line (Figure 20 and Figure 21).
For pipe sizing, refer to appropriate
guidelines in the condenser or condensing
unit installation manual. The grommets will
help seal in between the holes in the sheet
metal and the piping. If you are piping
through the back post foam panel, attach
grommet to the inside skin of the foam part.
If you are piping through post corner hole
location, use caution around electrical wires.
You will need to turn off power to the unit.
