INSTALLATION & OPERATION

Only experienced certified forklift drivers should use forklifts to move the cases. The case should only be lifted off the floor as high as necessary 

for transport. The forklift should be driven slowly, avoiding any abrupt motions or bumps.

The following forklift dimensions must be maintained to avoid damaging the case when it is lifted. Fork blades wider than 4" will not fit in the 

bases.

2-Door Cases

 

ƒ

Forks must extend from 26" to no more than 30" under the case.

3-Door Cases

 

ƒ

Use 48" long forks!

 

ƒ

Forks must extend from 39" to no more than 43" under the case.

4 & 5-Door Cases

 

ƒ

Use 48" long forks!

Important: Fork blades wider than 4" will not fit in the bases.

Spacer blocks are factory-installed in the end bases of 4 and 5-door cases that use bases taller than 3 1/2". These blocks limit the cases 

forward tilt at the opposite end from the forklift while it is being lifted and must be used when lifting 4 or 5-door cases with bases taller than 3 

1/2". 

See Figure 10 on page 27

.

For low shipping height applications, Zero Zone has optional expandable bases. As shipped, the base is 1 3/4" tall. It is attached with spacers 

that allow the base to slide away from the bottom of the case, creating a gap that allows the use of forklift blades thicker than 1 3/4".

When the case needs to move through an 80" door opening, the case is shipped with a 1" base on a wood pallet. Remove the case from the 

pallet to slide the case through the 80" doorway. Drain elbow will need installation on a 1" base. Use extra thick PVC cement.

Lineup Assembly

Zero Zone display cases have been engineered for continuous display. This means that any number of cases can be joined together to create 

a display of any desired length. The bottom of the end panel is protected with a removable steel plate that must be removed after the cases are 

set.

The cases will be ready for assembly after removal of the packaging material.

Case caulking instructions are shipped with every case, explaining the proper procedure for joining cases. 

See Figure 11 on page 28 

and 

See Figure 12 on page 29 

for instructions.

FIELD-INSTALLED CAULK SEALANT APPLICATION NOTES:

Butyl sealant is used to join cases and Silicone or NSF approved sealant is used for NSF compliance. Sealants should not contact one another 

as this may affect adhesion or color of each. 

Remove all shipping blocks applied to inside of base ends before joining cases.  

Remove End protection plate located below END on outside of case.

FAILURE TO FOLLOW THE INTENT OF CASE JOINING INSTRUCTIONS WITH SEALANTS WILL CAUSE FROST INSIDE THE CASE.

For NSF case installation compliance, the interior case seams need to be sealed using NSF approved caulk (not supplied).
