INSTALLATION
Leveling (Figure 2)
Casesmustbe installedperfectly leveltoallow efficientopera-
tion of the refrigeration coils and complete drainage of defrost
water. Sincealevel areaisseldomavailable,thefollowingsteps
arerecommendedto insurea levelinstallation.
1. Measure off and mark on floor the exact dimensions of
the case lineup. (Check blueprints).
2. Snap a chalk line at the locations for the front and back
positions of the base rails.
3. Mark locations of all joints (front and back).
4. Using a laser or transit, find the highest point along
both base rail position lines. Using the high point as a
reference, mark the difference directly on the floor to
each joint (front and back).
5. If you plan on using optional hat channels to raise the
case height, place them under each pair of bases. The
3 and 4 door hat channels will be angled slightly
to support the front and rear bases. (Figures 3 & 5).
6. Place the required number of shims under each base
or optional hat channel at each joint (front and back) to
equal the highest point.
The RVZC/P30 and 24, 2 through 5 door cases, have
segmented bases mounted at the ends and under the
center section of the case. The RVZC 1 door and BB
have full bases that run front to back and are located at
the ends and under the center sections of the case. The
RVZCWA& WBhave segmentedbasesthatrunfront to
back.
Tape all shims in place (Figure 2). Figure 4 shows the
correct orientation of shims under the base or channel.
7. Place additional support shims under all other bases
or hat channels (Figures 5A, 5B & 5C).
8. If you’ve purchased seismic restraints, specific instruc-
tions for attaching those restraints are included in your
document package. These instructions should be read
and followed before the line up is assembled.
