INTRODUCTION
The information contained in this manual pertains to the Evolution
display freezers which include:
RVZC30 RVZC24 RVZP30
RVZC30BB RVZCWA RVZP30BB
RVZC30T RVZCWB RVZP30T
RVZC30TBB RVZP30TBB
(The 30" 1-door case is based on the 24" door platform; for the 1door case, please use the coil assembly drawings, defrost and
electrical specifications listed for 24" door cases.) Specification
sheets for each of these cases is supplied separately and are available at www.zero-zone.com. All of these cases are used for merchandising ice, frozen food, or ice cream.
Zero Zone has made every effort to produce refrigeration equipment of the highest quality using state-of-the-art components. The
cases are built with the thickest insulation in the industry and a high
efficiency evaporator coil. Potential case features include:
• Brushless D.C. electronic motors or
PSC or shaded pole fan motors
• T-8 fluorescent lamps
• LED lighting or fiber optic lighting
• Standard-energy , low-energy or no-energy doors
These display cases were designed and tested using the following
industry standards:
• ASHRAE St andard 72-2005 – Method of Testing Commercial
Refrigerators and Freezers (ANSI Approved)
• ARI 1200- Performance Rating of Commercial Refrigerated Display Merchandisers and Storage Cabinets (ANSI Approved)
• UL 471- Commercial Refrigerators and Freezers (ANSI Approved) (equipment certified by ETL)

OF DELIVERY AND ALL CLAIMS FOR DAMAGES MUST BE
FILED WITH THE TRANSPORT A TION COMP ANY - NOT WITH
ZERO ZONE. The carrier will supply necessary report and claim
forms.
P ACKAGING
Each case in a line up is labeled to identify the line up 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 line up. The joint for two cases has the same
number-letter designation (Figure 1). 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).
Insulated dividers are factory installed to separate low and medium
temperature cases. They are also used to join different case models. Factory installed “Plexi” glass dividers separate refrigeration
circuits.
The first case in the line up (with it’s 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 other case in the line up has a
packet attached to the door that contains the specific information
for that case. The packing slip is taped to each case’s right hand
door.
Bumpers and kick plates 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 evaporating 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 leftside 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.
• NSF 7- Commercial Refrigerators and Freezers (ANSI Approved)
(equipment certified by NSF)
ASHRAE 72-2005 specifies the test conditions for the equipment.
It includes the ambient conditions of 75° F dry bulb and 55% RH. It
also specifies the door opening requirements for the performance
test. Doors are opened six times in one 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.
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 im-
0407
LOCA TION
These cases must not be installed in the direct rays of the sun or
near a source of radiant heat.
Be certain that the floor under the installation is of sufficient 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 inch 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.

INST ALLATION
Leveling (Figure 2)
Cases must be installed perfectly level to allow efficient 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 floor the exact dimensions of
the case lineup. (Check blueprints).
2. Snap a chalk line at the locations for the front and back
positions of the base rails.
3. Mark locations of all joints (front and back).
4. Using a laser or transit, find the highest point along
both base rail position lines. Using the high point as a
reference, mark the difference directly on the floor to
each joint (front and back).
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. (Figures 3 & 5).
A. Measure and mark exact case outline
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.
The RVZC/P30 and 24, 2 through 5 door cases, have
segmented bases mounted at the ends and under the
center section of the case. The RVZC 1 door and BB
have full bases that run front to back and are located at
the ends and under the center sections of the case. The
RVZC WA & WB have segmented bases that run front to
back.
Tape all shims in place (Figure 2). Figure 4 shows the
correct orientation of shims under the base or channel.
7. Place additional support shims under all other bases
or hat channels (Figures 5A, 5B & 5C).
8. If you’ve purchased seismic restraints, specific instructions for attaching those restraints are included in your
document package. These instructions should be read
and followed before the line up is assembled.
