INTRODUCTION
DISPLAY CASE MODELS (CONT.)
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. Potential case features include:
Brushless D.C. electronic motors, PSC*, or shaded pole fan motors*
T-8 uorescent lamps*
LED lighting
Standard-energy*, low-energy, or no-energy doors
These display cases were designed and tested using the following industry standards:
ASHRAE Standard 72-2005 — Method of Testing Commercial Refrigerators and Freezers (ANSI Approved)
AHRI 1200 — Performance Rating of Commercial Refrigerated Display Merchandisers and Storage Cabinets (ANSI Approved)
UL 471- Commercial Refrigerators and Freezers (ANSI Approved) (equipment certied by ETL)
NSF 7- Commercial Refrigerators and Freezers (ANSI Approved) (equipment certied by NSF)
DOE Compliant (All U.S. Sales)
ASHRAE 72-2005 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 6 times in 1 hour for 6 seconds. The door
opening test period is for 8 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.
*Not for U.S. Sales
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 uncrated 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.
PACKAGING
Each case in a lineup is labeled to identify the lineup and joint. The label uses a number and letter designation. The number indicates
the lineup. The letter indicates the case joint. Case joints begin with the letter A at the left most joint in the lineup when looking at the
front of the lineup. The joint for two cases has the same number-letter designation (Figure 1 on page 4). Back-to-Back cases have a
unique designation. The left most joint in the lineup when looking at the front of the case is labeled 1-A. The joint on the back of the case
is 1-A1 (Figure 1 on page 4).
Insulated dividers are factory installed to separate low and medium temperature cases. They are also used to join different case models.
Factory installed plexiglass dividers separate refrigeration circuits.
The rst case in the lineup (with the right side labeled “A”) has a packet attached to the door handle that contains the manual, special
instructions for installing ordered options, and touch-up paint if the cases are custom painted. Every case in the lineup has a packet
attached to the door that contains the specic information for that case. The packing slip is taped to the right-hand door of each case.
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 channels are shipped in the case that require the parts.
Materials for joining cases include caulk, joining bolts, splices, and T or J strips. These parts are supplied in cases that have a left-side
insulated divider or no left end. The parts are bagged and taped to the coil covers. The T and J strips are tied to the shelves.

INTRODUCTION
LOCATION
These 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. Out of level conditions will result in reduced
performance.
Wall cases (cases set with a back to a wall) and cases set back-to-back, should be positioned to allow a minimum 2-4" space behind the
back of the unit(s). This will allow necessary air to circulate behind the display case(s). Higher humidity stores with minimal air circulation
require a 4" gap.

INSTALLATION
LEVELING
Cases must be installed perfectly level to allow efcient operation of the
refrigeration coils and complete drainage of defrost water. Since a level
area is seldom available, the following steps are recommended to insure a
level installation.
1. Measure off and mark on oor the exact dimensions of the case
lineup (Figure 2A). (Check blueprints).
2. Snap a chalk line at the locations for the front and back positions
of the bases.
3. Mark locations of all joints (front and back).
4. Using a laser or transit, nd the highest point along both base rail
position lines. Using the high point as a reference, mark the difference
directly on the oor to each joint, front and back (Figure 2B).
5. If you plan on using optional hat channels to raise the case height,
place them under each pair of bases. The 3 and 4-door hat channels
will be angled slightly to support the front and rear bases. (Figure 3
on page 6 and Figure 5 starting on page 7).
6. Place the required number of shims under each base or optional hat
channel at each joint (front and back) to equal the highest point.
7. The RVZC30, RMZC24, RVCC30 and RMCC24, 2 through 5-door
cases, have segmented bases mounted at the ends and under the
center section of the case. The RVZC30 and RVCC30 1-door and
RVZC30BB and RVCC30BB have full bases that run front to back
and are located at the ends and under the center sections of the case.
The 3RMZC30WA and 3RMCC30WA have segmented bases that run
front to back.
8. Tape all shims in place (Figure 2C). Figure 4 on page 6 shows
the correct orientation of shims under the base or channel.
9. Place additional support shims under all other bases or hat channels
(Figure 5 starting on page 7).
10. Use a carpenter’s level to check installation as you go. The case
should be level from front to back and side to side. Install the case
at the highest point rst, if part of a lineup. Check the level on the
face of the glass doors and sides of the mullions. Do not use the
ceiling to check level.
11. If you’ve purchased seismic restraints, specic instructions for
attaching those restraints are included in your document package.
These instructions should be read and followed before the lineup
is assembled.

MOVING CASES
The Back-to-Back cases are shipped with wood planks that allow the use of pipe rollers. These wood planks should be removed after the
case is moved to its nal location (Figure 6 on page 11).
The RVCZ and RVCC and BB cases have steel protective support plates under the ends (not under insulated dividers). These are
designed to protect the end from Johnson Bar damage.

Only experienced 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, avoiding any abrupt motions or bumps.
The following forklift dimensions must be maintained to avoid damaging the case when it is lifted:
2-DOOR CASES
Forks must extend from 26" to no more than 30" under the case.
3-DOOR CASES
Use 48" long forks!
Forks must extend from 39" to no more than 43" under the case.
4 & 5-DOOR CASES
Use 48" long forks!
Fork blades wider than 4" will not t in the bases.

Spacer blocks are factory installed in the end bases of 4 and 5-door cases that use 4 ½" bases (Figure 7). These blocks limit the cases
forward tilt while it is being lifted and must be used when lifting 4 or 5-door cases with 4 ½" bases.
For low shipping height applications, Zero Zone has optional expandable bases. As shipped, the base is 1¾" 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 a 1½" thick fork truck blade
(Figure 8).

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.
The lineup is assembled by sliding one case up to the second case and then bolting the cases together. Bolt holes for the bottom of the
frame can be accessed by removing the right and left coil covers. The front and top bolt holes are visible on the steel end frame. The rear
bolt holes are exposed by removing the lift-out duct on the 30" door cases and by removing pocket covers on the 24" door cases. Figure
12 on page 13 show the bolt hole locations for each case. Bolt kits and instructions are supplied with the case.
Figure 9 gives instructions on applying caulk to the case joint before the cases are slid together. Once the cases have been caulked and
slid together, start the joining bolts, but do not tighten them. Slide the t-strip between the door frames (Figure 11 on page 13). Begin
tightening the bolts at the top rear, working down the back of the case and up the front, making sure that the front seams are ush. Bolts
are not designed to pull the cases together.
Two different model cases or two different temperature cases are connected using an insulated divider. Typically the divider is factory
assembled to one of the cases. Two styles of divider are provided. The rst style has a panel on each side with nut inserts in the panels.
Each side is bolted to the end frame. Instructions for assembly of this style are given in Figure 13 on page 14. The second style
divider uses a thru-bolt design. The divider is attached to one of the cases using short bolts. When the case is installed, the short bolts
are removed and long bolts are reinstalled to bolt both cases together. Instructions for assembly of this style case are given in Figure 14
on page 15. Bolts are not designed to pull the cases together.
For NSF case installation, the interior case seams need to be sealed using NSF approved caulk (not supplied) as shown in Figure 10 on
page 13.
The end panel protector support plates should be removed after the cases are set in their nal position.
Figure 9: Caulking Cases to be Joined
DO NOT APPLY EXCESS AMOUNTS OF BUTYL SEALANT THAT WOULD CAUSE IT TO SQUEEZE ONTO END FRAME
METAL AREAS. Caulk sealant used to join cases and complete the sealing requirements for NSF compliance should not come
in contact with butyl sealant. Apply to clean, dry surfaces free of contaminants that adversely affect adhesion and could change
color of sealant joint areas over time.
PROCEDURE FOR JOINING CASES
These procedures are critical! Failure to follow these guidelines
will result in a poorly functioning case. This is especially true of
low temp cases.
1. Apply two ¼" to 3/8" wide beads of butyl sealant, ½" in from
the inside and outside edges of foamed insulated ceiling, rear
wall, base, and door frame to be joined. Apply to only one
case joint to avoid excessive amounts of butyl sealant that
would squeeze out of the joint. Sealant is not applied to the
structural steel end frames. After cases are joined, caulk the
top and back exterior seams (if possible) at this time.
2. When joining ends of cases, caulk sealant should be applied
in the same manner for joints.

DRAIN LINE
The drain is located at the center of the case in the oor pan. The drain can be reached by removing the center coil covers and then
removing a fan motor. The 1" PVC drain outlet is located at the center front of the case behind the kickplate.
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 factory installs
a drain support at the front of the case on all 30" door cases. We supply a trap support that is eld mounted to the case (Figure 15). 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 insure proper drainage. Consult your local codes for minimum requirements.
