GENERAL INFORMATION
Introduction
The information contained in this manual pertains to
the following Maximizer display freezer: RMZC30XL.
This case is used for merchandising frozen food or ice
cream. The RMZC30XL has 30-inch wide doors and
utilizes the revolutionary new S-coil. Zero Zone, Inc.
of level conditions will result in reduced performance,
and will make the installation more difficult.
When located next to a wall, or backed up to another
case line-up, the cases should be positioned to allow
a minimum (4) inch space behind the back of a unit.
This will allow necessary air to circulate behind the
unit.
has made every effort to produce refrigeration
equipment of the highest quality using state-of-the-art
components.
This display freezer was designed to operate in an air-
conditioned store where the temperature is
maintained at 75°F or lower and the relative humidity
is 55% or lower.
Inspection
This display freezer was carefully factory tested,
inspected and properly packaged to ensure delivery in
the best possible condition. The equipment should be
uncrated and checked for damage immediately upon
delivery.
ALL CLAIMS REGARDING SHIPPING DAMAGES MUST
BE FILED WITH THE CARRIER/TRANSPORT COMPANY.
DO NOT FILE CLAIMS WITH ZERO ZONE, INC.
(The carrier/transport company will supply the
necessary report and claim forms.
Location
This freezer must not be installed where it will be
exposed to direct sunlight or near a source of radiant
heat.
INSTALLATION
DISCLAIMER,
Installation of the case; including proper footings &
stable support, leveling, drain plumbing,
refrigeration and electrical tie-ins, application of
local building codes, etc. are in whole the
responsibility of the store and the contractor/s
performing these jobs. Zero Zone, Inc. will not
accept responsibility for improper installations.
Leveling
Refrigeration equipment must be installed level and
plumb to allow efficient operation of the refrigeration
coils and complete drainage of defrost condensate
(water). Since a level area is seldom available, the
following steps are recommended to insure a level
installation.
1. Carefully, measure off and mark on floor with the
dimensions of the case line-up. (Check blueprints
– See Figure 1A)
2. Snap a chalk line at the locations for the front and
back positions of the base rails.
Be certain that the floor under the installation is of
sufficient strength to support a fully loaded case. Out

each joint (front and back) to equal the highest
FIGURE 1A
MARKING AND LAYOUT
3. Mark locations of all joints (front and back).
4. Using a transit or laser, 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 a transit or laser is not available, a water level
can be used to mark reference elevation points.
Water levels can be purchased from a contractor
supply house or hardware store for a minimal
cost.
6. A string level can also be used to mark elevation
points. The string level should only be used on
short line-ups to avoid problems with string sag.

place (See Figure 1B).

Joining Freezers
This reach-In freezer has been engineered for
continuous line-up. This means that any number of
cases can be joined together to create the desired
length. Reach-In freezers are built on permanent steel
skids to promote easy installation. The cases can be
moved by using case jacks, with a fork truck
(Telehandler) or with Johnson Bars.
To install Reach-Ins, perform the following steps:
1. Set the first Reach-In into the desired position and
level it. Run two (2) 3/8 inch diameter beads of
Butyl caulk 1/2 inch in from both the inner and
outer surfaces of the case end. (See Figure 2A)
2. Push the second Reach-In against the end of the
first. Level the second Reach-In. Remove the left
and right end floor covers and the rectangular
pocket hole covers, accessing the holes in the end
panels of each freezer as shown (Figure 2A).
Install tee strips between the doorframes at case
joints (See Figure 2B) Use the special screws and
nuts provided.

The drain is located at the center of the freezer in the
floor pan. The drain can be reached by removing the
center floor covers. The 1 inch PVC drain outlet is
located at the center front of the freezer behind the
kick plate. Figure 3A shows this location (the case is
tilted backward to clearly illustrate).

4. Each case joint at the top requires a 1-1/2 inch
wide roof gasket to merge the seam between the
two (2) cases. Installation of this gasket is very
important. Place the gasket back to where the
hinge panel begins and run it all the way forward
to the edge of the front panel. Cut it flush with the
front panel. (See Figure 2D)

DRAIN LOCATION
Install a tee to the outlet pipe. Next, connect the line
that returns to the rear of the case to connect the
defrost drain line. Then connect PVC drain trap to the
tee. The drain line must be pitched a minimum of (1)
inch per lineal foot. Connect the flexible defrost drain
