SHELVING INSTALLATION / OPERATION &
LIGHT SWITCH LOCATION
Shelf Installation Tips
1. Install all the shelf clips before installing the shelves.
2. Start at the bottom in terms of shelf installation and work
your way up.
3. Always lay the back of each shelf down on the rear clips
before the front.
WARNING
Do not use pliers or any crimping
tools when installing shelf clips.
Altering shelf clips in any way can
lead to shelving instability.
Install the top tab of the shelf
clip into the proper hole. Push
up on the bottom of the clip.
Bottom tab of the shelf clip will
fit tightly. You may need to
squeeze or twist the bottom of
the shelf clip to install.
LIGHT SWITCH LOCATION:
Light switch location depends upon the
GDM model. Most GDM models will
have the light switch located on the right
side of the ceiling inside the unit. Most
instances the switch is located next to the
temperature control. GDM-49’s and 72’s
have the switch located on the right side
of the evaporator housing along the interior
ceiling. GDM-9’s, 5’s, and GDM-5PT’s
have the switch located on the left side of
the ceiling. Some convenience store GDM’s
have the switch located behind the sliding
doors above the light bulb for example the
GDM-33SSL-54 and the GDM-33CPT-54.
G4SM-23 models have an additional switch
for the rotating display shelves. The switch
for the rotating shelves in the G4SM-23
models is located under the sign frame.
