INSTALLATION & OPERATION

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 level 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. On some cases, all bases are 

not directly in line from front to back. 

See Figure 4 on page 21 

and 

Figure 5 on page 22

 for base locations. The 3 and 4-door hat 

channels will be angled slightly to support the front and rear bases because the bases themselves are not in line.

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 

case is designed with minimal gaps between adjacent doors to provide a clean appearance. To maintain even, consistent gaps and proper 

door operation, the case must be leveled front-to-back and side-to-side. Check case squareness to within 1/8". 

See Figure 6 on page 

23

. Shims should not extend beyond the front case bases or they will interfere with the installation of kick plates. Tape all shims in place. 

The shims should be oriented to sit under the front and rear bends of each base.

7.  The RVLC30 2-door through 5-door cases have segmented bases mounted at the ends and under the center section of the case. The 

RVLC30 1-door and RVLC30BB have full bases that run front-to-back and are located at the ends and under the center sections of the 

case. Place additional support shims under all other bases or hat channels, leaving no gaps taller than one shim.

8.  Tape all shims in place (

See Figure 7 on page 24

). 

See Figure 8 on page 25

 for the correct orientation of shims under the base or 

channel.

9.  If you are joining coolers to freezers, RVMC cases should be set with a slight backward tilt to offset the forward lean of a fully loaded case. 

When joining a freezer and cooler in a short lineup, both cases should be tilted back with an additional 3/16" of shims under the front 

bases after the case is leveled. 

See Figure 2A on page 19

. On long lineups, the tilt back on the coolers should gradually increase while 

working away from the cooler/freezer joint until the last case has an additional 3/8" of shims under the front base and the tilt back on the 

freezers should gradually decrease to no additional shims while working away from the cooler/freezer joint. 

See Figure 2B on page 19

.

10. 

If you’ve purchased seismic restraints, specific instructions for attaching those restraints are included in your document package. These 

instructions should be read and understood before the lineup is assembled.

Case Movement

CAUTION! 

 

DO NOT PULL ON THE MULLIONS WHEN MOVING THE CASE. THE END FRAME CAN BE USED TO PUSH/PULL 

THE CASE. DOLLIES MAY BE PLACED AGAINST THE CASE BOTTOM, BUT AVOID CRUSHING THE BUMPER 

SUPPORT OR DRAIN PIPE.

 WHEN USING A J-BAR, IT MUST NOT CONTACT THE SHEET METAL OF THE BUMPER SUPPORT, BUT SHOULD 

CONTACT THE SHEET METAL OF THE BOTTOM FOAMED PANEL. THE BUMPER SUPPORT WILL BE DAMAGED 

IF LIFTED BY A J-BAR. BE CAREFUL NOT TO PIERCE THE SHEET METAL WITH THE CORNER OF THE J-BAR.

The RVLC30 and RVLC30BB cases have steel protective support plates under the ends (not under insulated dividers). These are designed to 

protect the end from Johnson Bar damage. Per NSF, these must be removed after cases are set.

The Back-to-Back cases are shipped with wood planks that allow the use of pipe rollers. These wood planks should be removed after the case 

is moved to its final location (

See Figure 9 on page 26

).

Care should be taken when moving the cases. The doors should be secured so they cannot open while the case is moved.
