REPLACING NOSING ANTI-SWEAT
HEATER
To replace the heater:
1. Turn OFF the power to the merchandiser.
2. Remove a louver from one end. It doesn’t
matter which end.
3. Remove exterior nosing extrusion by
placing fingers at the back end of the
extrusion and pulling forward until
it separates from the interior nosing
extrusion.
4. Unplug and remove existing anti-sweat
heater. The anti-sweat heater plug is routed
on RH side from front of merchandiser
(end opposite the main serial plate).
5. Install new anti-sweat heater as shown and
route plug to jumper harness; plug in.
6. Do the following to reattach exterior
nosing extrusion to interior nosing
extrusion: There are two joining locations
“A” and “B” that must be fastened to
the interior nosing extrusion. “A” can be
positioned in place by hand. Use a rubber
mallet to snap “B” into place at interior
extrusion. A light to medium tap is all that
is required.
NOTE: It is easier to reinstall plastic
extrusion if wide PTM is removed.
7. Replace discharge air louver, retainer and
fasteners.
8. Turn on power to merchandiser, and check
for proper operation.
