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 floor 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 (Fig. 1) can be removed
with a screw gun. As for case shipping braces, the same
would be applied with sled runner or caster constrction.
If the braces are metal brackets or locks they can be
removed with a screw gun. If they are wood blocks they
can be removed with a J-bar. Note: Shipping braces are
normally located at each corner of the case. Some case
models with casters will use bracing that surrounds the
casters entirely and some will use braces that affix to
the toekicks at each corner. (Shipping braces used vary
and are based on case design for best transport.)
5. Carefully, if horizontal supports, lift case up and off the
pallet. Remove dust cover. Installation hardware ships in
a marked packet located inside the case. Remove dust
cover. Installation hardware ships in a marked packet
located inside the case. (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
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
the store floor to the proper staging area. First remove
all crating then all sled runner, caster, and/or power cord
shipping braces. (Dependent on case design.)

SUPPORTS
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 ref-
erence for determining the proper height of the shim-pack
levelers. A laser transit is recommended for precision and
requires just one person. Level adjustable feet by twisting,
if applicable, or shim as necessary under vertical station-
ary or caster supports as this will help ensure that the
case is not settling over time.
7. Locate horizontal or vertical (caster) support positions
along the chalk line (Fig. 2). Spot properly leveled shim
packs at each support location.
8. (SLED RUNNERS) If necessary, drill a hole in each end of
every horizontal support (Fig. 3) and fasten to the floor
with concrete anchors. Note: The holes do not need to be
in the exact locations specified here. Be sure that the
anchors are close to the end of the horizontal supports
and at each corner of the case.
C A U T I O N
Failure to properly level the case could result in
lack of proper condensation drainage leading to
failure of the unit.

2. Once the case is properly placed on the shim packs,
check the vertical plumb of the case by placing a bubble
level on the rear wall. Add/remove shim packs as needed.
For the horizontal level, repeat this process after placing
the bubble level on the front sill.
3. Install the bumper, if applicable, into pre-attached bumper
track and snap into place. (Most self-contained cases ship
with bumper pre-installed.)
4. After sufficient time has passed to allow for bumper
shrinkage, cut away the excess bumper for final fit and fin-
ish. Be certain to use an appropriate cutting tool (tubing-
or PVC-cutter) to ensure a smooth cut.
5. Install case shelves and reconnect lights. Be aware that
differing shelf configurations will affect energy consump-
tion and case performance.
6. Install toekick/compressor compartment access panel
back onto the base of case, if applicable.
C A U T I O N
These cases are not designed for excessive
external weight. Do not walk on top or inside
of cases. Doing so may result in case damage
and/or personal injury.
▲
LINE-UP & INSTALLATION
Single Case
1. Move the case into position. Using a “J” bar, raise the end
of the case (under cross support), and lower the horizontal
support on to the shim packs. Repeat on the other end of
the case.

Fig. 3 Seismic anchoring locations (sled runners)
9. (CASTERS) If necessary, attach two brackets at two sepa-
rate corners of the case (Fig. 4) and fasten to the floor
with concrete anchors. Note: The brackets do not need to
be affixed in the exact locations specified here. Howev-
er, be sure that the anchors are close to the corners and
that at least two brackets are used, one at each corner.
You can use more than two brackets for anchoring if you
want further support this way.
W A R N I N G
Be certain that your hands and feet are out of
the way before lowering the case. Failure to do
so may result in serious injury.
•
C A U T I O N
Locate the horizontal or vertical (caster) sup-
ports under unit before removing from pallet.
Failure to do so will damage the finished metal
if correct lift points are not identified prior to
removal.
•
C A U T I O N
Do not obstruct vetilation around the base of
the display case condensing unit. Obstructing
could cause the case to not operate correctly
and failure to maintain product temperatures.
•

ELECTRICAL
Electrical hookups are made through the junction box which
can be accessed by removing the lower panel to the compres-
sor compartment.
When connecting to the power supply on the case, field wiring
should exit box from the side furthest away from case wiring to
allow more room inside for wiring connections. The case must
be grounded. For more detailed electrical wiring information
(see Appendix A1).
Prior to plugging in and starting up the case always check the
data tag located on the left end exterior panel or top interior of
the case, as well as the voltage label found on the main power
cord (Fig. 5) 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.
C A U T I O N
Be certain that all electrical connections are
compliant with local codes.

Fig. 8 Airflow pattern (1-tier)
AIRFLOW & PRODUCT LOAD
Hillphoenix cases provide maximum product capacity within the
refrigerated air envelope. Please keep products within the ap-
propriate load limit.
It is important that you do not overload the food product display
so that it impinges on the airflow pattern (Fig. 8). Overloading
will cause malfunction and the loss of proper temperature lev-
els. The designed load limit is 3" above the deck for critical tem-
perature products and 6" for non-critical temperature products.
For full technical reference drawings with load limit lines refer
to pages 4-6.
DEFROST
Cases are equipped with Temperature Terminated Off-Time
defrost.
The defrost cycle is very important in that it ensures correct
operation of the case. It is activated and controlled by the
thermostat which temporarily stops the condensing unit, al-
lowing the evaporator to shed the build-up of ice. The control-
lers synchronize the defrost between condensing units via the
auxiliary ports.
W A R N I N G
Always keep product within the designated air
curtain. Failure to do so may result in case
malfunction and product losing proper tempera-
ture, resulting in sub-standard operation and
increased chances of food contamination.
▲
Note: The tier configuration will vary. The diagrams above depict the airflow for a 2-tier and/or 4-tier airflow pattern.
C A U T I O N
Proceed to the loading only once the display
case has reached the proper temperature set-
ting.

CASE CLEANING
A periodic cleaning schedule should be established to maintain
proper sanitation, insure maximum operating efficiency, and
avoid the corrosive action of food fluids on metal parts that are
left on for long periods of time. We recommend cleaning once
a week. Further suggestions for case cleaning include the fol-
lowing:
• To avoid shock hazard, be sure all electrical power is turned
off before cleaning. In some installations, more than one
disconnect switch may have to be turned off to completely
de-energize the case.
• All surfaces pitch downward to a deep-drawn drain trough,
funneling liquids to the center of the case where the waste
outlet is located for easy access. Check the waste outlet to
insure it is not clogged before starting the cleaning process
and avoid introducing water faster than the case drain can
carry it away.
• To clean the LED luminaires, shut off the lights in the case,
then wipe the luminaires down with a soft, damp cloth.
Avoid using harsh or abrasive cleaners as they may dam-
age the lights. Be certain that the luminaires are complete-
ly dry before re-energizing.
• Clean from top to bottom when cleaning the display case to
avoid cross contamination.
• If any potentially harmful cleaners are used, be certain
to provide a temporary separator (e.g., cardboard, plastic
wrap, etc.) between those cases that are being cleaned
and those that may still contain product.
• Avoid spraying any cleaning liquids directly on the electrical
connections.
• Allow cases to be turned off long enough to clean any frost
or ice from coil and pans.
• Remove toekick and clean underneath the case with a
broom and a long-handled mop. Use warm water and a dis-
infecting cleaning solution when cleaning underneath the
cases.

SHOCK HAZARD
Always disconnect power to case when servicing
or cleaning. Failure to do so may result in serious
injury or death.
Fans and Pressure Plate
1. Disconnect power to the case and wait for fans to come to
a complete stand-still.
C A U T I O N
Only lift the pressure plate and/or coil cover for
a qualified inspector or a trained service provid-
er. Failure to do so may result in damage to the
refrigerant system.

2. To reach the fans and pressure plate first remove the
base deck with help of the pre-drilled access lift supplied
(Fig. 9 & 10). Note: It is recommended that more than
one person lift the deck.

3. To access the underside of the fans first remove the
screws on the top ends and front sill of the pressure
plate cover (Fig. 11). Lift the pressure plate by use of the
provided lift handles (Fig. 11). There are hinges shared
between the pressure plate and coil covers. Note: It is
recommended that more than one person lift the pres-
sure plate. The topside of pressure plate will rest against
the topside of the coil cover, exposing the underside of the
pressure plate and fans.
4. Clean as necessary. Use a spray bottle filled with an ap-
proved mild detergent and warm water.
5. Be sure to move the pressure plate back to its original
position after cleaning and/or inspection is complete.

Coil Inspection
1. Disconnect power to the case and wait for fans to come to
a complete stand-still.
2. Remove the top two screws at both ends of the coil cover
(Fig. 11), as well as the screws from the top ends and
front sill of the pressure plate cover (Fig. 11). Be sure to
save the removed screws for reassembly.
3. Carefully, without bending the sheet metal cover, with the
use of the handles provided, gently slide the coil cover
with the pressure plate assembly forward to expose the
evaporator coil.

Condenser Air Intake Filter
Clean and remove the debris from the condenser air intake fil-
ter monthly. If filter is not cleaned regularly the head pressure
will rise and cut all power off to the compressor by means of the
pressure switch.
The filter will either have a slide-out screen or pull-off magnetic
application. Note: Prior to cleaning, be sure to remove the
filter from the case completely and move to a distance far
enough away that no debris will come in to contact with the
case or the product inside. Both can be cleaned with an air
hose and/or rinsed with water. Be sure to remove all debris
and wait until completely dry before placing back on to the
case. (Top mounted compressors will not have an air intake
filter.)
Cleaning Condensate Dissipator Pan
Inspect the dissipator pan (Fig. 12) at least once every six
months. Ensure you disconnect the electrical power supply
and make sure you DO NOT touch the elements as they reach

PARTS SUBJECT TO WEAR & SPARE PARTS
Most spare parts carry clear, complete ID information. It is
important that the refrigerated case parts be replaced by
analogous parts of equivalent safety and quality: to order
spare parts please contact Hillphoenix, stating the case model
and serial number, found in this manual or on the case ID
plate, and provide a description of the component and the
desired quantity. Refer to the Parts section in the back of the
manual for parts ordering and to identify parts that may need
to be replaced.

Cleaning Condenser
The condensers used on the condensing units gather dust and
dirt and must be cleaned regularly. Under normal working con-
ditions this task must be executed at least once a month using
a soft-bristled brush and a vacuum cleaner. A dirty condenser
will reduce the display case performance: it will also result in
increased energy consumption. (Fig. 13)

Such tasks require qualified personnel with specific technical
skills (e.g. refrigeration system specialists, electricians etc.)
and must be carried out at least once a year. See the sched-
uled maintenance table for a list of the main tasks. (Fig. 13).
If inspection reveals any rust, cracks and etc...it will be neces-
sary to carry out repairs and/or replacement of parts so that
the case meets code and the display case is in prime operat-
ing condition. To enhance safety, it is recommended that you
always seek the advice of a specialized technician before
carrying out any repair work.
