INTRODUCTION
Case Features
Zero Zone produces high quality refrigerated display cases using state-of-the-art components. The cases are built with the thickest insulation in
the industry and a high efciency evaporator coil. Case features include:
Brushless DC electronic 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.

INSTALLATION & OpERATION
Delivery Inspection
These display cases were carefully factory-tested, inspected, and properly packed to ensure delivery in the best possible condition. The
equipment should be unpackaged, uncrated, and checked for damage immediately upon delivery. DAMAGE MUST BE NOTED AT 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.
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 (such
as PTM) inside the case to deform or warp.
Packaging
Numbered labels identify the order of cases in a lineup (See Figure 1). The rst number indicates the store order number. The second number
indicates the lineup. The third number indicates the joint in a lineup (from left to right, when viewed from the front of the case). Back-to-back
cases follow the same labeling.
The rst case in the lineup (Case 1) has a packet shipped inside the case that contains the manual, special instructions for installing optional
features, and touch-up paint for custom-painted cases. Other cases in the lineup contain specic information for that case. The shop order is
taped to each case’s right-hand door.
Bumpers and kickplates are shipped on top of the case. Shelves are tie-wrapped and blocked inside the case for shipping. Other accessories
like drain traps, drain pans, condensate evaporation pans, and hat channel rails are shipped in cases that require those parts.
Materials for joining cases—including caulk, joining bolts, splices, and end ller posts—are shipped in each case to be joined.
The door is prevented from opening during shipment with the use of a door-holding shipping bracket. The bracket is screwed to the top of the
case at each door and should be removed when the case is unpacked.
Location
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 unit(s). This will allow necessary air to circulate behind the display
case(s) and prevent condensation. Higher humidity stores with minimal air circulation require at least a 4" gap. Recommended minimum 2" gap
between cases on end-to-end installations.

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. Do not push/pull on the mullions when moving the case.
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.
The cases have steel protective support plates under the ends (not under insulated dividers) to protect the end panel from J-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 MODELS INSTRUCTIONS
2RVMC24 Forks must extend 20" to 24" under the case from either end
3RVMC24 Forks must extend 26" to 30" under the case from either end
4RVMC24 Forks must extend 39" to 43" under the case from either end
6RVMC24 Forks must extend 44" to 47" under the case from either end
2RVMC30 Forks must extend 26" to 30" under the case from either end
3RVMC30 Forks must extend 39" to 43" under the case from either end
4RVMC30 Forks must extend 44" to 47" under the case from either end
5RVMC30 Forks must extend 44" to 47" under the case from either end
OPTIONAL BASES
For low shipping height applications, Zero Zone has optional expandable bases to accommodate up to 1 3/4" thick forks (See Figure 2). To use
a forklift on cases with 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.
If a case needs to move through an 80" door opening, the case will be factory-installed with a 1" base and will be shipped on a wooden pallet.
Remove the case from the pallet to slide the case through the 80" doorway. The drain elbow will be shipped loose and must be installed using
extra thick PVC cement after the case is through the doorway. The 1" base will be set into an elevation kit (See Figure 3).
FIGURE 2: Expandable Base FIGURE 3: Elevation Kit for 1" Base

6 • Installation & Operation
INSTALLATION & OpERATION
Spacer blocks are factory-installed in the end bases of 4 or 5-door cases that use bases taller than 3 1/2". These blocks limit the case's forward
tilt while it is being lifted by a forklift (See Figure 4).
Leveling
Cases should be set level from 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. If your case uses optional hat channel rails to raise the case height, place shims under the hat channel rails. On 3 and 4-door cases, hat
channel rails must be angled slightly to support the front and rear bases because the center bases themselves are not aligned (See Figure
7 through Figure 10 starting on Page 7).
