service single-deck merchandiser with sliding doors.
STORE CONDITIONS
Hillphoenix cases are designed to operate in an air-condi-
tioned store that maintains a 75°F (24°C) store temperature
and 55% (max) relative humidity (ASHRAE conditions). Case
operation will be adversely affected by exposure to excessively
high ambient temperatures and/or humidity.
REFRIGERATION SYSTEM OPERATION
Air-cooled condensing units require adequate ventilation for
efficient performance.
THIS UNIT CONTAINS R-290 FLAMMABLE REFRIGERANT. USE
CAUTION WHEN HANDLING, MOVING OR SERVICING THE DISPLAY
CASE. AVOID DAMAGING THE REFRIGERANT TUBING WHICH COULD
INCREASE THE RISK OF A LEAK.

FLOOR PREP
1. Ask the general contractor if your current copy of the build-
ing dimensions are the most recently issued. Also, ask for
the points of reference from which you should take dimen-
sions to locate the cases.
2. Using chalk lines or a laser transit, mark the oor where
the cases are to be located for the entire lineup. The lines
should coincide with the outside edges of the case feet.
3. Move case as close as possible to its permanent location.
Remove all crating and shipping braces above the ship-
ping pallet. Loosen the plastic dust cover from the pallet,
but leave cover over the case to protect it while removing
the case from the pallet.
4. The power cord shipping brace can be removed with a
screw gun if attached to the pallet. Otherwise, the power
cord is attached to the case with a zip tie and needs to be
removed carefully.
5. Carefully, if horizontal supports, lift case up and off the
pallet. Remove dust cover. Check for loose components
in the packaging. Do not dispose of of loose components.
If it cannot be determined where the loose components
belong, call Hillphoenix technical support. (Hillphoenix
self-contained display cases are sometimes designed with
casters. In most situations, one or two persons can easily
move the case into position.) If there are casters simply
roll them on to the store oor to the proper staging area.
First remove all crating then all sled runner, caster, and/or
power cord shipping braces. (Dependent on case design.)
6. Leveling is necessary to ensure proper operation of the
refrigeration system and drainage of the condensate.
Locate the highest point on the positioning lines as a
reference for determining levelers. A laser transit is rec-
LOCATION
This refrigerated display case has been designed for displaying
and storing perishable food product. It is engineered for air-
conditioned stores with a maximum ambient of 75°F and 55%
relative humidity.
When selecting the location for placement of this case, avoid
the following conditions:
Excessive Air Movement
1. Doors
2. Air-conditioned vents
3. Other air sources
Excessive Heat
1. Windows
2. Sun
3. Flood lamps 8 feet or less from the product
4. Other heat sources
ommended for precision and requires just one person.
When in nal position level adjustable feet (Fig. 1 & 2) as
needed so that the casters are not engaged to the oor.
To do so, rst rotate the nut at the adjustable feet coun-
terclockwise. Turn feet until engaged to the oor and the
casters no longer make contact to the ground.
Fig. 1 Vertical supports
Fig. 2 Adjustable leveling feet and casters
7. (CASTERS/BULLET LEGS) If necessary, attach two brack-
ets at two separate corners of the case (Fig. 3) and fasten
to the oor with concrete anchors. Prior to attaching
brackets be sure to turn the power OFF to the case and
unplug power cord.
CAUTION
Failure to properly level the case could result in
lack of proper condensation drainage leading to
failure of the unit.

2. Move the case into position. The case has a two lane pal-
let with connecting strips and enforcement steel panels.
3. Use a (philips) to remove the screws on each of the steel
panels at each corner of the pallet. After the steel panels
are removed pull away the connecting strips (Fig. 4) at
each palet side. Insert pallet jack or fork lift at the gap left
by the connecting strips, turn up the case and take away
the two side/end pallets. Repeat as needed.

spliced in a line-up, install the kickplate linking plate after
the front skirting board is xed.
16. Repeat steps of this sequence for all remaining cases. Be
certain to properly level all cases.
17. Install the price tag molding using double sided sticky
tape. Do not use hardware to install the tag molding as
this will interfere with the assembly of the center cover
panel.

ELECTRICAL
This case has a NEMA 5-15P plug (locking NEMA-15P plug
when applicable) that will need to be connected. Note: The
locking NEMA L5-15P plug can replace the standard NEMA
5-15P plug via the connector disconnect that is found in the
condensing unit compartment on the customer right hand
side of the case.
The case must be grounded. For more detailed electrical wir-
ing information (see Appendix A1).
Power Cord Locking L5-15P
Prior to plugging in and starting up the case always check the
data tag located on the outside back panel of the case, as well
as the voltage label found on the main power cord (if applica-
ble) which can be found at the rear base panel. Note: Check
that the voltage of the receptacle you are going to use for
power and the voltage required for the case match.
CAUTION
Be certain that all electrical connections are
compliant with local codes.

Cord Replacement (5-15P to L5-15P)
Prior to replacing the power cord and plug, be sure to
DISCONNECT POWER to the case before proceeding. The
power can be disconnected at the main panel breaker in
the building. Just turning OFF the case with the main power
switch will NOT disconnect power coming to the case. Note:
The front control panel has a clear cover to help protect
against accidental access to switches. The controls can be
accessed by use of a tool put through the provided holes in
the cover.
To replace the standard 5-15P cord with the locking cord
L5-15P in the eld it is a quick disconnect of the connector
and ground terminal (Fig. 20) within the CDU compartment;
accessed from the rear air grill.

Electronic Cutoff
The CNZLA/CNEZLA compressors have an electronic cutoff
mechanism such that the LRA (Locked Rotor Amps) has zero
(0) amp draw after 4 seconds when the rotor becomes locked.
Power Supply & Light Switch
1. After the main power cord located at the base panel of the
case is plugged in and the power switch (Fig. 23) ipped
to ON the case should begin normal operations.
2. After establishing power the light control switch (Fig. 23)
(if applicable) located on the exterior front panel can be
ipped to the ON position. The case should now be fully
operational and all lights functioning when in the ON posi-
tion (if applicable).
3. Note: The front control panel has a clear cover to help
protect against accidental access to switches. The con-
trols can be accessed by use of a tool put through the
provided holes in the cover.
Temperature Probe Connections
1. The top probe is for defrost temperature and the bottom
probe is the case temperature (Fig. 22).
Access locations and/or R-290 compartment congurations
will vary based on case design. See page 18 for a compressor
compartment diagram.
