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).

6. Place the required number of 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 11).
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 12). 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 17).

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 13). Note: Do not add extra shims
under Ultra Narrow cases.
9. When joining a freezer and cooler in a short lineup (2 cases: 1 freezer and 1 cooler), both cases should be tilted back with an additional
3/16" of shims under the front bases after the case is leveled (See Figure 14).

10. When joining a freezer and cooler in a long lineup (3 or more cases: at least 1 freezer and at least 1 cooler), 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 15).
11. 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.
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 bottom of the end panel is protected with a removable steel plate that must be removed after the lineup is set.
The cases will be ready for assembly after removing the packaging material.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.
Case caulking instructions are shipped with every case, explaining the proper procedure for joining cases (See Figure 16 on page 14).A
case must be prepared with Butyl caulk before setting the next case in the lineup.
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.
For NSF case installation compliance, the interior case seams must be sealed using NSF-approved caulk (See Figure 17 on page 15). Do
not allow Butyl sealant and NSF-approved caulk to contact one another as this may affect adhesion or color of each.
An insulated divider is used to join two different case models or two 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.
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.

1. Apply two 1/4" to 3/8" wide beads of BUTYLSEALANT, at Ceiling,
Rear Wall, and Base, as shown with dashed lines.Apply to only one
(1) case at joint, not both cases, as excessive amounts of sealant
may squeeze out of joint.
2. After cases are joined and tightened, caulk the top and back exterior
seams, if possible, to further ensure there are no voids in the joint.
3. This process must be repeated at all case joints.
FOLLOWING THIS PROCEDURE IS CRITICAL FOR
SEALING JOINED CASES CORRECTLY!

1. Cases to be joined properly before continuing to step 2. Refer to
CASE – JOINT CAULKING INSTRUCTION for more information.This
document is included in your information packet.Avoid excess caulk
during this step to prevent it from coming out of the joints. This will affect
step 2 as butyl and silicone sealants do not mix.
2. Apply silicone-based caulk-sealant bead to areas shown at left to meet
sealant requirements for NSF-approved installations.
3. Apply small beads of sealant smoothly at seams between end frame
of case and end panel or insulated divider, but do not thin or feather
excessively, because it may affect adhesion.
*Seal between all access holes and cut-outs between end frame of case.
NOTE: Caulk sealant lines are shown dashed in views at left. Field caulk
sealant must be applied in a continuous fashion to seal the affected area
with the desired bead width and penetration.
SURFACES OFAREAS TO BE CAULKED SHOULD BE CLEAN, DRY,AND FREE OF FROST.
SURFACE TEMPERATURE OF THESE AREAS SHOULD BE ABOVE 40ºF.
Required Sealing for NSFApprovable Installation Only

Ultra Narrow CaseAnchoring
The Crystal™Cooler Ultra Narrow (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-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 18). Two case-to-
wall support brackets will be provided when anchoring the Ultra Narrow to a wall (See Figure 19 on page 17).

Door Leveling
On Crystal™coolers with same-swing doors, the door-to-door gap should be 3/8". On
Crystal™coolers with French-swing doors, there should be a 7/16" gap between doors
at the handle side and a 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.
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 20). 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 21). 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.

INSTALLATION & OpERATION
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 22). 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.
Kickplates
Each case is shipped with a front kickplate. Cases with end panels are
shipped with 1 side kickplate per end panel. Cases that join together are
shipped with a kickplate splice.
Front and side kickplates are attached to the case bases using Tinnerman
clips. Position the front kickplate so the ange is on top and facing outward.
The screw (supplied) goes through the kickplate and into the Tinnerman clip
(See Figure 23).
There is a natural gap between the top of the kickplate and the underside
of the Crystal Merchandiser® that allows airow of 50 CFM per door. If more
airow is required, contact the factory to order optional louvered kickplates
(provides 150 CFM per door).
