Brown and Son WA Cooler & Freezer, Installation & Maintenance Instructions Manual

Roof Cap & Curb Installation 

(Figure #14)

Wiring the Door Heater, Lights & Windows

All freezers and some coolers are shipped with a 120V peripheral heater around the door to eliminate 
condensate and keep the door frame and jamb from “sweating”. Likewise most freezer windows are also
designed with a 120V heater for the same reason.

Vapor Proof Light

This light is internally wired to the light switch. Only source power needs to be wired into the junction box 
powering the light. Maximum bulb size is 100 watts. Do not operate with globe until walk-in is at operating
temperature.

Fluorescent Lights

These lights are field installed and will require both source power and internal wiring by a qualified electrician.

The above will be wired to door switch via “J” Box on interior of door section in most cases.

All installation should be in accordance with NSF and prevailing electrical code. 

Warning! 

When installing your Walk-in cooler or freezer, always use a

qualified electrician for all your wiring needs. Refer to wiring diagram included
in this manual.

Warning! 

Never penetrate rubber roof cap, (with exception of rubber

grommet unit mounting screws.)
