*The priority should be in that order, if the Coil Top Trim holes won’t match up when the plenum is
screwed to the Front, unscrew the Coil Frame from the wall and shift it over until it fits. The Fan trim piece
can shift side to side with respect to the frame, and you can redrill the holes in the back wall.

Cable Connections
• All of the interior wiring is done utilizing
color-coded, twist-lock, watertight plugs
and type J thermocouple plugs. Make sure
all plugs bottom out.
• All interior wiring must be done before the
ceiling plenum is installed.
9.
Hooking up the System
A properly licensed electrician must next hook
up the system to a shut off attached to a
nearby wall. The electrical specifications are
located on a sticker attached to the controller.
10.
Installing Refrigeration
After the unit has power, the refrigeration
technician can install the refrigeration, running
½” and (usually) 1- 1/8” copper tubing through
the provided hole in the ceiling panel. Make
sure the suction tubing is properly wrapped
with Armaflex, and all work is done in good
practice according to local code. Coils arrive
with a holding pressure of 60 psi nitrogen.
11.
Setting the Ceiling Plenum
The ceiling plenum can now be set in place,
plugged in, and mounted using black thumb
screws. I you have trouble lining up the holes,
remember that the fan side upper trim is
clamped in place and can be slid forward or
backwards, and you can loosen the trim piece
over the coil frame as well. Also remember
that the interior plenum support angle can be
relocated if need be.
