CANOPY AND SHELF LAMP BALLAST
The ballast for the canopy and shelf lamps is
located behind the canopy on the left-hand end
(when facing case) of the merchandiser.
To access the ballast:
1. Remove screws at bottom edge of canopy and
rear of top panel.
2. Remove the canopy by pulling it forward.
3. Remove the top panel by lifting it up.
4. Service or replace ballasts as required.
5. Reassemble items as they were originally
installed.
NOTE: Rail lamp ballast is located behind the
lower front panel.
CANOPY ANTI-SWEAT HEATER
The canopy anti-sweat heater location is shown
below. Connections are in the electrical wireway.
