GENERAL INFORMATION
DESCRIPTION OF CASES: The refrigerated display cases described in this handbook
are part of the Hill PHOENIX, Origin2design series. Specifically covered in this manual is
model OSAA, self-contained service deli case.
STORE CONDITIONS: Hill PHOENIX cases are designed to operate in an air conditioned
store with a system that can maintain 75
O
F (24OC) store temperature and 55 percent (maximum) relative humidity (CRMA 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 ventilation for
efficient performance of condensers. Machine room temperatures must be a minimum of
65
O
F in winter and a maximum of 95OF in summer. Minimum condensing temperatures
should be no less than 70
O
F.
RECEIVING CASES: Examine fixtures carefully for shipping damage and shortages. For
information on shortages contact the Service Parts Department at 1-800-283-1109.
APPARENT DAMAGE: A claim for obvious damage must be noted on the freight bill or
express receipt and signed by the carriers agent, otherwise the carrier may refuse the claim.
CONCEALED DAMAGE: If damage is not apparent until after the equipment is unpacked,
retain all packing materials and submit a written request to the carrier for inspection within
15 days of receipt of equipment.
LOST ITEMS: This equipment has been carefully inspected to insure the highest level of
quality. Any claim for lost items must be made to Hill PHOENIX within 48 hours of receipt
of equipment.

CASES
MOVE ON
CASTERS
FOR EASIER INSTALLATION
CASTERS MAY BE DISCARDED.
ROLL OUT OF TRUCK. When there is a truck - level
delivery dock, cases may be rolled directly from the
truck to the store floor. [CAUTION] If skid boards are
required to unload cases, casters should be removed
prior to sliding them down the skid; after which they
can be reinstalled on case.
ROLL TO LINEUP POSITION. Casters may remain in
place to move the cases to staging areas around the
store, prior to final installation. When ready for final
line-up, roll the case to set position, then remove
casters.
REMOVE COTTER PIN. Removing the casters is
easy. Simply flatten and hammer out cotter pins
then lift the case with “J” bar, and the casters will
fall off.
[CAUTION] Make certain hands are out of the way.
ORIGIN2cases are manufactured and shipped to
stores with casters installed on the base frame to
make the job of moving cases easier for everyone
involved with the manufacturing, shipping and installation process.
Casters not only speed up the process, but they also
reduce the chance of damage from raising and lowering cases with ”J” bar to place them on dollies,
skates or rollers. In most situations, one or two persons can move the case with ease.

Consult With General Contractor
Ask the general contractor if there
have been changes in the building
dimensions since the print you are
using was issued. Also, ask the
points of reference from which you
should take dimensions to locate the
cases.
Set Shims On Basehorse Locations
Locate basehorse positions along
chalk lines. Spot shim packs at each
basehorse location.
2
Snap Chalk Lines
Mark floor where cases are to be
located for the entire lineup.
3
Snap Lines On Base Rail
Locations
Snap lines where base rails are positioned, not the front or back edges of
the cases. See case cross section
drawing, pages 3-4 for rail location
dimensions.
4
Level Floor. Use Laser Transit
Leveling is necessary to assure proper case alignment. Locate highest
point on chalk line as reference for
determining height of shim-pack
levelers. A laser transit is recommended for precision and requires
just one person.
6
Position First Case In Lineup,
Remove Casters, Level
Roll first case into position. Raise
case from end under cross support
using “J” bar. Remove cotter pins and
casters. [CAUTION! Keep hands from
under case] Level case on shims.

Position Next Case In Line Up
Roll case approximately 2’ from
adjoining case. Remove casters on
the end nearest to the next case.
Allow casters to remain on opposite
end to assist in pushing cases together - then remove them.
Ask about our case installation video available by request through your local Hill PHOENIX Sales or Field Service
Representative. Spanish version available.

Install plenum covers under deck pans.
The plenum covers are shipped loose in
the case and are installed between the
lower rear baffle and the fan plenum.
6
Seal joints along pipe chase seam with
the caulk provided.
Now that cases have been
positioned and leveled, you
may proceed to trim-out
case lineup. Trim parts have
been designed to be applied
easily with only a small
number of fasteners
required. Most external
parts are adjustable to
achieve almost invisible,
snug-fitting joints and a
high level of excellence in
fit and finish.

TRIM OUT
1
Tighten all joint bolts. Draw up tightly,
but do not over tighten.
2
Adjust polymer master bumper joints, if
required. First loosen bumper screws.
3
Slide bumper joint to the center of the
joint between the two cases. Use screw
driver in hole provided.
4
Slide master bumper left or right to
close seam as required. Bumper joint
neatly finishes any gap that may remain.
5

right adjustment as required.
10
Install curved front panel joint (if cases
come equipped with curved front panels). Curved panel joints are shipped
loose in the case and are attached with
the screws provided. Wide joints (1”)
are for case-to-case joining and narrow
joints (1/2”) are for cases with ends.
11
Attach lower front panel (for cases on
11” baseframes). Slots and tabs are
designed for easy installation without
fasteners. The lower front panel is slotted to allow adjustment left or right as
required.
12
Install top sill joint. The top sill joints are
shipped loose in the case. The front lip
of the joint fits into the crevice between
the top sill and the glass pressure bar.
The rear lip is attached to the back of
the case with the screws provided.
13
Install rear sill joint. The rear sill joints
are shipped loose in the case. The bottom portion of the joint should be slid on
the rear sill first then the top lip fits
between the rear sill and the mullion.
Secure the joint underneath the rear sill
with the screws provided.
14
Install the “J” rail onto the case base
rail. For cases with an 11” baseframe,
the “J” rail easily slides over the base
rail and requires no fasteners. Space
“J” rails evenly along the base rail (2 “J”
rails per 6’, 8’, and 12’ case). For cases
with the 7” baseframe there is a single
“J” rail that is screwed into place.
15
Insert kickplate into “J” rail. Slide the
kickplate up and behind the lower front
panel bracket then down on the “J” rail.
NOTE: An easy technique for one
person is to press against nose
bumper with leg as you guide
bumper into channel with a screen
spline. Insert bottom first.

Insert nose bumper into master bumper
channel. Roll nose bumper into channel
along entire lineup (up to 96’). We recommend that the nose bumper be left in
the store 24 hours before installing. DO
NOT STRETCH the bumper during
installation as it will shrink to its original
length and leave a gap.
REFRIGERATION
COMPONENTS
Refrigeration components for the
OSAA-6’ are easily accessible in the tank and
underneath the case. The expansion valve
and suction line 1/4” access valve are both
located in the left hand front side of the tank
and are accessible without lifting the fan
plenum. These components may be reached
by lifting only the left hand deck pan which
minimizes the need to remove product.
The diagram below illustrates all of the
refrigeration components in the OSAA-6’ case.
The components surrounded by the box are
located within the case tank. Basic definitions of
these components are listed on the following

Accumulator
- A device installed on the suction line that is used to boil off small amounts of liquid refrig-
erant so liquid does not reach the compressor.
Compressor
- An electrically driven piston pump that pumps vapor refrigerant from a low pressure level
to a higher pressure level.
Condenser
- The component in a refrigeration system that transfers the heat that was absorbed by the
refrigerant in the evaporator and the heat of compression from the system by condensing the refrigerant.
Condenser Fan
- Fan that forces air through the air cooled condenser to aid heat transfer.
Dual Pressure Control
- A device that protects the compressor from low charge and high pressure.
Evaporator
- The component of the refrigeration system that absorbs heat from the air by boiling liquid
refrigerant to vapor.
Evaporator Fans
- Fans that circulate air through the case and force air through the evaporator to aid heat
transfer.
Filter Drier
- A device installed on the liquid line of a refrigeration system that removes water and other
impurities from the refrigerant in the lines during initial start-up.
High Pressure W
arning Light - Indicator light that warns the operator that the system pressure is to high.
Receiver
- The component in a refrigeration system that stores liquid refrigerant that is not being used by
the system in low load conditions or when the system is shut down.
Service V
alve - A manually operated valve in the refrigeration system that is used for various service oper-
ations such as isolating the high or low sides of the system.
Suction Line Solenoid
- A device that prevents liquid from entering the compressor.
Thermostatic Expansion V
alve (TXV) - A valve that controls the flow of liquid refrigerant to the evapo-
rator coil and also separates the high pressure side of the system from low pressure side of the system.
Thermostatic Expansion V
alve (TXV) Bulb - A bulb that is attached to the suction line of the evapora-
tor that controls the TXV. Inside the bulb is a charge that reacts to temperature and regulates the flow of
refrigerant through the expansion valve.

PLUMBING
The drain outlet is located front and
center of the cases for convenient access
and is specially molded out of ABS material.
The “P” trap, furnished with the case, is
constructed of schedule 40 PVC pipe. Care
should be given to assure that all connections are water tight and sealed with the
appropriate PVC or ABS cement.
The drain lines can be run left or right
of the tee with the proper pitch to satisfy
local drainage requirements. The drain can
be piped to a evaporative drain pan at the
owners option.
The kickplate is shipped loose with the
case for field installation, therefore you
should have open access to the drain line
area.
If the kickplate has been installed, you
will find it very easy to remove. See instructions below, or the trim out section of this
manual on page 9.

DEFROST
AND
TEMP CONTROL
• Electric defrost termination control sensor bulb location
• Electric defrost termination probe location
• Temperature control sensor bulb location (OSA)
It is important to consult the control
setting guidelines shown on page 17 before
setting defrost times. Further adjustment may
be required depending on store conditions.
These cases are equipped with Electric
Defrost. The sensor bulb and probe for electric
defrost termination and the sensor bulb for
temperature control are located behind the
front baffle at the location shown in diagram 1
below.
The defrost termination control thermostat and the temperature control thermostat
are located under the rear sill behind an easily
removable cover, as shown in diagram 2.

Cases have been designed to provide maximum product capacity within the refrigerated
air envelope. It is important that you do not
overload the food product display so that it
impinges on the air flow pattern.

USE

MAINTENANCE
CASE CLEANING
Case is designed to facilitate cleaning. There is a wide
radius formed on the front and back of the inside bottom
that helps accelerate liquid flow and eliminates difficult-toclean sharp corners. All surfaces pitch to a deep-drawn
drain trough that angles toward the front and center of case
where the waste outlet is located for easy access.
The coil is covered to keep food fluids from entering, but
the cover lifts up easily when coil cleaning is desired. The
fan plenum also lifts up for cleaning, exposing a major
portion of the inside bottom of the tank. Make certain the
coil cover is properly closed after cleaning to avoid air
leaks. Front return air grills snap out for cleaning; no fasteners are used.

CLEANING PROCEDURES
• 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. W
e recommend cleaning once
a week.
• 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.
• Check 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.
• Avoid spraying cleaning solutions directly on fans or electrical connections.
• Avoid using high pressure water to flush the tank. A hose without a nozzle should provide enough pressure for cleaning
purposes. Always use cold water.
• Allow cases to be turned off long enough to clean any frost or ice from coil and flue areas.
• Remove and clean discharge honeycomb. You may need to use spray detergent and a soft, long bristle brush.
• Use mild detergent and warm water. When necessary, water and baking soda solution will help remove case odors. Avoid
abrasive scouring powders or pads.
• When cleaning non-glare glass be sure to use a standard glass cleaner and not a multi-purpose cleanser or combination
cleanser.
• A mixture of white vinegar and water or isopropyl alcohol straight from the bottle is very effective in cleaning “build-up” on
non-glare glass.
• Under no circumstances should abrasive cleaning solutions such as scouring powders or steel wool be used to clean nonglare glass.
• When cleaning rear door tracks be sure to remove the rear doors and clean from the outside channel to the inside channel
using the wipe-out groove machined into the track.
• Remove front panels and clean underneath the case with a broom and a long handled mop. Instructions for removing the
front panels can be found on page 9 of this manual.
• Use warm water and a disinfecting cleaning solution when cleaning underneath the cases.

FANS
The evaporator fans are equipped with 5 watt
fan motors, 1550 RPM’s. The motor has a counter
clockwise rotation when viewed from the shaft end.
The fan blades are 6” in diameter and the blades are
pitched according to the charts below. It is impor
tant that the blade pitch be maintained as specified. Do not attempt a field modification by
altering the blades.
Fan motors may be changed with an easy
two-step process without lifting up the plenum,
thereby avoiding the necessity to unload the entire
product display to make a change:
1. Unplug the fan motor, easily accessible out
side the plenum
2. Remove three fasteners, then lift out the
entire fan basket
