Again, MAKE SURE THAT THE POWER IS DISCONNECTED and

remove the cover plate from the pilot light and switch on the front of

the door section. Remove the two screws that attach the pilot light and

switch assembly to the switch box and pull the pilot light and switch

assembly out of the switch box enough to expose the terminal screws

on the device.

Examine the wiring in the switch box and identify the two black leads

from the heater wire that are connected either to two switch terminals

or to one switch terminal and to a wire connector. Refer to the wiring

diagram of the walk-in cooler in the "Electrical Connections" section

of this manual. HINT: After positively identifying the two leads to the

heater wire, cut the leads off, but leave an inch or two remaining on

the switch terminal(s) and/or wire connector. In so doing, these short

lengths of lead will positively identify the proper points of connection when the replacement heater is installed.

Remove the original heater wire from the jambs and threshold and discard it.

INSTALLATION OF THE REPLACEMENT HEATER

Insert the two lead wires of the replacement heater into the access hole in the heater wire raceway that leads to the

pilot light and switch junction box. NOTE: The section where the lead connects to the heater wire SHOULD NOT

BE BENT! Locate the connector sections as close as possible to the access hole, but KEEP THEM STRAIGHT!

Secure the connector sections in place with a short piece of electrical tape.

Temporarily arrange the heater wire assembly.
