Refrigerant Piping Connections:
CL condensing unit refrigerant piping
connections are located in the upper corner of the
service vestibule side of the unit (opposite the
condenser section) as shown in Figure

The piping connections are protected with a
shipping cover that must be removed prior to
copper connection and installation.

Evaporative Condenser Field Piping
Connections:
There are two field water connections that must be
made for the evaporative condenser. There is a
¾” PVC socket city make-up water connection
and a 2” PVC socket drain connection (as shown
on the next page). Connect this drain to a sanitary
sewer or other code permitted drain. These
connections can go through the base or the wall of
the unit.
There is a cutout in the base with a cap that is 1”
tall and the cap is sealed to the unit base to prevent
any leaks in the unit from penetrating into the
building. Any piping through the base must go
through a field cutout in this cap. The pipes must
be sealed to the cap once the piping is complete to
prevent any leaks in the unit from penetrating into
the building.
A field cutout must be made in the wall if the
evaporative condenser piping is to go through the
unit wall. This cutout must be sealed once the
piping is installed to prevent water from leaking
into the unit.
