features may include:
Electronic fan motors
Zero Zone ChillBrite®LED Lighting
Zero Zone CoolView®Ultra
™Doors
Testing Standards
These display cases were designed and tested using the following industry standards:
NSF 7 – Commercial Refrigerators and Freezers (ANSI Approved) (equipment certied by NSF)
NSF 51 – Food Equipment Materials (ANSI Approved) (equipment certied by NSF)
UL 471 – Commercial Refrigerators and Freezers (ANSI Approved) (equipment certied by ETL)
ASHRAE Standard 72 – Method of Testing Commercial Refrigerators and Freezers (ANSIApproved)
AHRI 1200 – Performance Rating of Commercial Refrigerated Display Merchandisers and Storage Cabinets (ANSIApproved)
DOE Compliant (All U.S. Sales and U.S. Territories)
ASHRAE Standard 72 species the test conditions for the equipment. It includes the ambient conditions of 75°F dry bulb and 55% RH. It also
species the door opening requirements for the performance test. Doors are opened six times in one hour for six seconds. The door opening
test period is for eight hours during one 24-hour performance test.As an example, a 5-door case will have 240 door openings during one 24-
hour test. Consult the factory if your store exceeds these test conditions.

Delivery Inspection
Zero Zone display cases are carefully factory-tested, inspected, and packed to ensure delivery in the best possible condition. The equipment
should be unwrapped and checked for damage immediately upon delivery. DAMAGE MUST BE NOTEDAT TIME OF DELIVERY, ANDALL
CLAIMS FOR DAMAGES MUST BE FILED WITH THE TRANSPORTATION COMPANY, NOT WITH ZERO ZONE. The carrier will supply
necessary report and claim forms. Contact your Zero Zone sales representative or the service department to arrange for replacement parts.
Do not leave, store, or hold case outdoors in direct sunlight or high ambient temperature. With the end panels on, the case is airtight;
the inside temperature of the case will increase, and the heat will be unable to escape. This could potentially cause any plastic inside
the case to deform or warp.
Packaging
Each case in a lineup is labeled to identify the lineup and joint. The label uses a two digit number designation, separated by a decimal. The
rst number indicates the case lineup. The second number indicates the case joint. Case joints begin with the number “1” at the left-most joint
in the lineup when looking at the front of the lineup. The rst case in the lineup will be labeled on the right end and the second case in the lineup
will be labeled on the left end. The numbers on each end to be joined will match (See Figure 1).
The rst case in a lineup (with the right side labeled “x.1”) has a packet attached to the shelving that contains touch-up paint. Every case in
a lineup has a packet attached to the shelving that contains important information about the case and/or lineup and, if applicable, special
instructions for installing ordered options.
Bumpers and kickplates are shipped on top of the case. Shelves for the case are tie-wrapped and blocked into the individual cases. Other
accessories like drain traps, drain pans, and condensate evaporation pans are shipped in the cases that require the parts.
Materials for joining cases—including caulk, joining bolts, splices, and end ller posts—are shipped in each case to be joined.
The doors are prevented from opening during shipment with the use of door-holding shipping brackets. The brackets are screwed to the top of
the case at each door and should be removed when the case is unpacked.
Location
Zero Zone cases must not be installed in the direct rays of the sun or near a source of radiant heat. Be certain that the oor under the
installation is of sufcient strength to prevent sagging. Uneven surfaces will result in reduced performance.
Cases should be set to allow a minimum 3" of space behind the back of the units. This will allow necessary air to circulate behind the
display cases and prevent condensation. Higher humidity stores with minimal air circulation require at least a 4" gap.Aminimum 2" gap is
recommended between cases on end-to-end installations.All minimum spacing requirements may increase if seismic restraints are used.
Building softs must be set back at least 6" from the front of the case to allow access to electrical wiring on the top of the case.

INSTALLATION & OpERATION
Moving Cases
Various tools and equipment may be used to move cases including, but not limited to, a forklift, a Johnson bar, a pallet jack, furniture rollers,
casters, or a Rol-A-Lift. Be careful to avoid damaging the store ooring. Only certied forklift drivers should use forklifts to move the cases. The
case should only be lifted off the oor as high as necessary for transport. The forklift should be driven slowly; avoid abrupt motions or bumps.
Use the end frame to push/pull the case. For best results, push/pull lower on the end frame. Do not push/pull on the mullions as this
can cause the mullions to bend.
When using a Johnson bar, only contact the sheet metal of the bottom foamed panel. Do not contact the bumper support. Be careful
not to pierce the sheet metal with the corner of the Johnson bar.
 When using a pallet jack or furniture rollers, only place them under the oor panels. Do not place them under the bumper support or
drain pipe as that will crush the components.
Cases have steel protective support plates under the end panels (not under insulated dividers) to protect them from Johnson bar damage.
Make sure that a forklift with the proper fork dimensions is available. Forks must be 48" long, 1 1/2" to 1 3/4" thick, and no more than 4"
wide to t the bases. Refer to the table below for instructions.
CASE MODEL INSTRUCTIONS
4ORMCD (2-Door) Forks must extend 20" to 24" under the case from either end
6ORMCD (3-Door) Forks must extend 26" to 30" under the case from either end
8ORMCD (4-Door) Forks must extend 39" to 43" under the case from either end
12ORMCD (6-Door) Forks must extend 44" to 47" under the case from either end
OPTIONAL BASES
For low shipping height applications, such as 80" tall doorways, Zero Zone offers 1" bases or 1 3/4" bases.
Cases with 1" bases will be shipped on a wooden pallet and are not forkliftable. The case can be removed from the pallet to slide it through
the 80" doorway.
The 1 3/4" bases are expandable to accommodate up to 1 3/4" thick forks (See Figure 2). To use a forklift on the expandable bases, raise
the case with a Johnson bar and place wooden blocks under the case, allowing the base to expand enough for forks to be inserted.
Cases with 1" or 1 3/4" bases will be set into nested bases (See Figure 3). 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 ller blocks) are included in the end bases of 4 and 6-door cases that use bases which are 4 1/2" or taller. These
blocks limit the case's forward tilt while it is being lifted by a forklift. The forks should be inserted above the spacer blocks (See Figure 4).

INSTALLATION & OpERATION
Leveling
Cases should be set level right to left to allow complete drainage of defrost and condensate water. Since a level oor area is seldom available,
the following steps are recommended to ensure a level installation. If your case uses seismic restraints, specic 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 oor the exact dimensions of the case lineup (See Figure 5). Refer to the xture plan or oor 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, nd the highest point along both base position lines. Using the high point as a reference, mark the difference
directly on the oor to each base, both front and back (See Figure 6).
5. Place enough shims under each base 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 7).
After the case is set, additional shims may need to be added at specic base locations (See Figure 8 on page 7).
6. The case must be leveled front-to-back and side-to-side. Ensure that the case is set square to within 1/8". Measure squareness from top
right corner to the bottom left corner, and then again from the top left corner to the bottom right corner. Measurements should be equal
(See Figure 9 on page 8).
7. Cases should be set with a slight backward tilt to offset the forward lean of a fully loaded case. We recommend an additional 3/8" of shims
be installed under the front bases after the case is leveled.
8. Place additional support shims under any bases with gaps taller than one shim. Note: Total height of shims should be less than 3/4".

INSTALLATION & OpERATION
LineupAssembly
Zero Zone display cases have been designed for continuous display so that multiple cases may be joined together to create a lineup of any
desired length. The lineup will be ready for assembly after removing the packaging material.
Acase lineup must be properly aligned, which starts with properly leveling the case (See "Leveling" on page 6). It is crucial to use a laser
level to measure the high points in the oor and properly shim each base location.
The bottom of the end panels are protected by steel support plates, which must be unbolted and removed before the lineup is set. There are
bolts that go up through the support plates into the underside of the foamed oor.
Acase must be prepared with Butyl caulk before setting the next case in the lineup. Case caulking instructions and caulk are shipped with every
case (See Figure 10 on page 9).
Move the next case into position and bolt it to the rst case using the joining bolts that are provided. Begin tightening the bolts at the top rear,
working down the back of the case and up the front, making sure that the seams are ush. Do not pull cases together using joining bolts.
For NSF case installation compliance, the interior case seams must be sealed using NSF-approved sealant (See Figure 11 on page 10). Do
not allow Butyl caulk and NSF-approved sealant to contact one another as this may affect adhesion or color of each.
FIGURE 9: Case Squareness
1. Measure squareness from top right corner of the case to the bottom left
corner of the case.
2. Measure again from the top left corner of the case to the bottom right
corner of the case.
3. Measurements should be equal. Difference should be no more than 1/8".
