INSTALLATION & OpERATION
Cases with 1" or 1 3/4" bases will be set on hat channel rails or into nested bases (
. The drain elbow will be shipped loose and
must be installed using extra thick PVC cement after the case set in place.
Spacer blocks (also called filler blocks) are included in the end bases of 4-door, 5-door, and 6-door cases that use bases which are taller than 3
1/2". Spacer blocks limit the case's forward tilt while it is lifted by a forklift. Forks should be inserted above the spacer blocks (
leveling
Cases should be set level right to left to allow complete drainage of defrost and condensate water. Since a level floor area is seldom available,
the following steps are recommended to ensure a level installation. If your case uses seismic restraints, specific instructions for attaching
seismic restraints are included in your document package. Read and understand these instructions before assembling the lineup.
1.
Measure off and mark on the floor the exact dimensions of the case lineup (
). Refer to the fixture plan or floor plan.
2. Snap a chalk line at the locations for the front and back positions of the bases.
3. Mark locations of all joints, both front and back.
4.
Using a laser level or transit, find the highest point along both base position lines. Using the high point as a reference, mark the difference
directly on the floor to each base, both front and back (
).
5. If your case uses optional hat channel rails to raise the case height, place shims
under
).
On 3 and 4-door cases, the center bases are not aligned, so the hat channel rails must be angled slightly to support the bases (
10 through Figure 13 starting on Page 8
).
6. Place enough shims under each base or optional hat channel rail to equal the highest point. Shims should not extend beyond the front
case bases or they will interfere with installing trim. The shims should be oriented to sit under the front and rear bends of each base. Tape
all shims in place (
See Figure 8 and Figure 9 on page 7
).
