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.

! CAUTION! DO NOT STAND ONTOP OFACRYSTAL MERCHANDISER®.THE TOP OFTHE CASE IS NOT DESIGNED TO
SUPPORTTHE WEIGHT OFA PERSON.
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 NOTED AT TIME OF DELIVERY,AND ALL
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, condensate evaporation pans, and hat channel rails are shipped in the case 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 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
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 or end panel.
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 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, 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.
FIGURE 2: Expandable Base

6 • Installation & Operation
INSTALLATION & OpERATION
Cases with 1" or 1 3/4" bases will be set on hat channel rails or 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-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 (See Figure 4).
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. If your case uses optional hat channel rails to raise the case height, place shims under the hat channel rails (See Figure 7 on page 7).
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 (See Figure
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).

7. 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. Ensure that the case is set square to within 1/8" (See
Figure 15). After the case is set, use at least a 48" level to ensure the case is level. Add additional shims as needed under specic bases.
This will reduce door sag/sawtooth (See "Door Leveling" on page 11).
8. Standard depth and Deep 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 (See Figure 14). Note: Do not add extra shims
under Ultra Narrow cases.

9. When joining a Crystal™freezer to a Crystal™cooler, both cases should be tilted back with an additional 3/16" of shims under the front
bases after the case is leveled. When joining multiple freezers and coolers in a lineup, 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 16).
10. Place additional support shims under any bases or hat channel rails with gaps taller than one shim. Do not place shims between bases
and hat channel rails. Total height of shims should be less than 3/4".
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.

INSTALLATION & OpERATION
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.
A1" wide trim piece is shipped inside the case to seal the vertical gap between cases being joined. It needs to be attached on the right of the
rst case using the top and bottom joining holes in the extrusion. The next case in the lineup should slide up to the trim piece so that the door
seals against the trim piece.
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 18 on page 15).
Move the next case into position and bolt it to the rst case using the 4 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.
The interior case seams must be sealed using silicone sealant for NSF compliance (See Figure 19 on page 16). Do not allow Butyl caulk
and silicone sealant to contact one another as this may affect adhesion or color of each.
An insulated divider is used to join 2 different case models or 2 different temperature cases.The divider is typically factory-installed to one of the
cases. There are 2 types of insulated dividers:
1. Between a Crystal™ cooler and a different case: The insulated divider has a panel on each side with nut inserts in the panels; each side is
bolted to the respective end frames. Do not pull cases together using joining bolts.
2. Between 2 Crystal™coolers: The insulated divider uses a thru-bolt design. The divider is attached to one of the cases using short bolts for
shipping. When the cases are installed, the short bolts are removed and longer joining bolts are installed to bolt the cases together. Do not
pull cases together using joining bolts.
Ultra Narrow CaseAnchoring
The Ultra Narrow case (RVMC24UN) must be anchored to either another case or a wall to ensure the case will not tip forward. The
Back-to-Back Ultra Narrow (RVMC24BBUN) does not require anchoring. It may be used as the anchor for the Ultra Narrow case.
Two case-to-wall support brackets will be provided when anchoring the Ultra Narrow to a wall (See Figure 17). Two case-to-case support
brackets will be provided when anchoring the Ultra Narrow to another case. The Ultra Narrow case must be set 3" away from the other case for
proper ventilation, so a provided trim piece must be eld-installed to cover the gap (See Figure 20 on page 17).

*DO NOTAPPLY BUTYLCAULK ON SEAFOOD OR BAKERY CASES.Butyl caulk never cures and emits vapors that affect seafood and
bakery products. Recommended alternative caulk: Polyurethane-based (full curing, durable, moisture-activated) or silicone-based (full curing).
IT IS CRITICAL TO FOLLOW THIS PROCEDURE TO ENSURE CASESARE PROPERLY SEALED.
SURFACES TO BE CAULKED MUST BE CLEAN, DRY, FREE OF TAPE/ADHESIVE, AND FREE OF FROST (ABOVE 40ºF).
Note: Apply Butyl caulk to only one case—not both cases. The caulk will spread out when the cases are pushed together, and
excessive caulk may squeeze out of the joint. Wipe away any caulk that squeezes out. Butyl caulk will not mix with silicone sealant
(used for NSF sealing), which will affect adhesion of both.
1. Apply 3/8" thick beads of Butyl caulk* along the ceiling, rear wall, and bottom of the case where indicated by the dashed lines in the
drawing. Caulk must be continuous with no gaps. Always apply 2 beads where specied. Caulk must be applied around a plexiglass divider
and not onto the divider itself, if applicable.
2. After cases are joined and tightened, caulk the top and back exterior seams, if accessible, to ensure a tight seal.
3. See Figure 19 on page 16 for information about NSF compliance sealing with silicone sealant.
Before joining the cases, remove all packaging material on the display case, including any spacer blocks inside the bases. Repeat
caulking between each case in the lineup.

Note: Cases must be properly caulked and joined before NSF sealing. Wipe away any Butyl caulk that squeezes out of the case joint.
Butyl caulk and silicone sealant will not mix, which affects the adhesion of both. See Figure 18 on page 15.
1. Apply silicone-based sealant in small, continuous beads where indicated by the dotted lines in the drawing. Do not thin or feather, as that
will affect adhesion.
2. Sealant must be added between cases at case joints, between a case and an end panel, and between all access holes and cut-outs in the

Door Leveling (Door Sag/Sawtooth)
Doors must be leveled before the bumper and kickplate are installed.
For same-swing doors, the door-to-door gap should be 3/8". For French-swing doors, the door-to-door gap should be 7/16" at the handle side
and 3/8" at the hinge side. To set the proper gaps, loosen the screws holding the top or bottom door mounting plates, then shift the door.

INSTALLATION & OpERATION
BOTTOM MOUNTING PLATE
To move the bottom mounting plate, the center locking screw (located behind the bumper)
must be loosened.
1. To remove the bumper, use a athead screwdriver to pry it up from the bottom. Lift the
edge, and then slide the screwdriver down the entire length of the bumper to loosen it.
Once the bottom edge is disconnected, use a hammer to tap the screwdriver upwards
and disengage the bumper from the upper track. Remove the bumper.
2. Loosen the center locking screw by 2 turns, accessed through the hole in the bumper
support plate (See Figure 21). This will allow the bottom mounting plate to shift. Do
not remove the center locking screw.
3. Tap the door’s aluminum extrusion with a rubber mallet to shift the door. Once the door
is in position, retighten the center locking screw.
TOP MOUNTING PLATE
1. To access the top mounting plate, remove the top trim piece. This will require a Phillips
bit and a 1/4" hex screw bit.
2. Loosen all 3 screws that secure the slotted plate by 2 turns (See Figure 22).
Do not remove the screws.
3. Tap the door's aluminum extrusion with a rubber mallet to shift the door. Once the door
is in position, retighten all screws.
Drain
The drain is located at the center of the case in the oor pan. The 1" PVC drain outlet is
located at the center front of the case behind the kickplate.
The drain line exits the case in the center. The lateral runs of drain pipe should be installed
through the bases (See Figure 23). There is no room in front of the base for the drain pipe
because the kickplate installs directly to the front of the bases.
Install the tee to the outlet pipe and a drain trap to the tee. Plug the open end of the tee
using the clean-out plug supplied with the drain trap kit. The drain line must be pitched
away from the case. The tee, drain trap, and plug are supplied with the case. The drain
trap must be level. The drain trap should be primed with water after installation. The
drain line must be pitched away from the case enough to ensure proper drainage. Consult
your local codes for minimum requirements.
Cases with 1" bases are shipped on wooden skids or pallets. The forward drain section,
tee, and “R” trap are shipped loose for eld installation.
Condensate Removal System
Zero Zone remote cases can be equipped with a condensate removal system. The system uses a drain pan with pump located behind the
kickplate and a condensate evaporation pan mounted on the top of the case.
Condensate water and any liquid spilled in the case will drain into the drain pan. The pump is equipped with a oat that turns the pump on when
there is a sufcient liquid level. Liquid is pumped through a plastic hose through a check valve and into the condensate evaporation pan. The
evaporation pan is equipped with a heater and a oat switch to turn on when the heater is submerged in liquid. When the heater is energized,
the evaporation pan will be extremely hot and should not be touched. The pump and evaporation pan should be cleaned regularly.Any spilled
product, other than water, should be cleaned to prevent odors.
