Pre-priming the hinge gas cylinders:
WARNING
If the front glass is raised before the hinge
gas cylinders are pre-primed, the glass
could break and/or cause personal injury.
After the case has been installed and leveled,
make sure the shipping braces have been
removed. Pre-prime the cylinders by gently
lifting the front glass approximately 6”, then
close. Repeat this movement at least 4 or 5
times before fully opening the lift glass.
NOTE
If the glass does not stay in the open
position, see “Lift Glass Cylinder
Replacement” in this manual.
Rear Rail Cover & Close-off Installation
Position rear rail cover (1) over rear raceway
opening and secure with screws in every
hole.

Lift Front Glass Leveling Instructions
Accurate leveling is critical for the proper
operation of the lift glass on this case.
In some instances, setting the case on an
apparently level floor can cause the lift glass
to fit improperly. If there is any twist in the
body, it could cause the lift glass not to fit or
work properly.
The emphasis when leveling this case must
be on making sure the lift glass works and
seals properly.
The case should be leveled across the top,
close to the hinge, and on the color band.
A 4 foot level is recommended, and
both
places should be level! This will enable
the lift glass to fit and work properly.
If the lift glass still doesn’t close or line-up
properly, adjust legs or add shims to case
corners. Adjustment and shimming will
ensure proper operation and alignment of
the lift glass.
The handle on the lift glass must rest evenly
on the color band. Proper lift glass sealing
is essential for good product refrigeration.
NOTE
Do not anchor the base to the floor or
enclose the case until the lift glass is
fitting properly and working correctly.
