NSTALLATION
Preparation
1. Using store blueprints, measure off and mark
on floor the exact dimensions/locations of the
case footprint.
2. Snap a chalk line for the front and rear
positions of the base legs.
3. Mark the location of each joint from front to
back lines.
4. FLOORS ARE NOT LEVEL!!! When
working with two or more cases to be joined, the
whole lineup must be leveled on the same plane,
left to right and front to back. This means that the
entire lineup must be brought up to the level of
the highest case in the lineup.
Along the lines previously marked, find the
highest point of the floor by:
• Walking the floor and noticing any dips or
mounds;
• Using a string level; and
• Using a transit.
Leveling
Position the first case at the highest point on the
floor. Work outward from that point to create the
case line-up. Use a 48 inch (1220 mm) or longer
level for end-to-end leveling. The rear edge of the
top foam panel of the case is a good location for
the level at the rear of the case, and the top rail is
a good location for the level at the front of the
case. For leveling the case front-to-rear, a 24 inch
(610 mm) level should be placed on the bottom
display pan. If the case has a factory installed
end, the level should be placed on the canopy
support brackets on top of the case. Suggested
level locations are shown in the following
illustrations.
P/N 0501930_A
Level the case by all four corners. Start at the
rear by placing as needed the provided shims
under each end of the rear base rail. The shims
are long enough to allow the adjoining case to be
leveled with the same shim. When the rear of the
case is level end-to-end, move to the front of the
case. Insert shims as needed at each front corner
so that the front is also level from end-to-end. At
this point, check to see if the case is level front-
to-rear. If it is not, add or remove shims until the
case is level front-to-rear.
The case should be solidly supported at least
every 2 feet (610 mm). Once the case is level, if
any gaps are present, shims should be inserted
under the front and rear base rails approximately
in line with the cross-members to support the
front and rear of the case.
It is the installing contractor's responsibility to
ensure the merchandiser has adequate support
under each cross-member. Leveling and support
are critical prevent air and water leaks.
