Welcome to the ORIGIN display case family. We’re very pleased you
joined us.
This installation and operation handbook has been especially
2
prepared for everyone involved with ORIGIN display cases – owners,
managers, installers and maintenance personnel.
You’ll find this book different than traditional manuals. The most
dramatic difference is the use of many more illustrated instructions to
make it easier to read and to help you get the most from this innovative
new design. When you follow the instructions you should expect
remarkable performance, attractive fits and finish, and long case life.
We are interested in your suggestions for improvement both in case
design and in this handbook. Please call/write to:

GENERAL INFORMATION
DESCRIPTION OF CASES: The refrigerated display cases described in this handbook
2
are part of the Hill PHOENIX, Origin design 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 75OF (24OC) store temperature and 55 percent (maxi-
mum) 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
65OF in winter and a maximum of 95OF in summer. Minimum condensing temperatures
should be no less than 70OF.
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.
TECHNICAL SUPPORT: If any technical questions arise regarding a refrigerated display
case contact our Customer Service Department in Richmond at 1-804-526-4455. For any
questions regarding our refrigeration systems or electrical distribution centers contact our
Customer Service Department in Conyers at 1-770-285-3200.

COMPONENT DEFINITIONS
Access Valve - Access port on the evaporator that allows service personnel to check system pressure.
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 Warning 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 Valve - 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 Valve (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 Valve (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 connec-
tions are water tight and sealed with the
appropriate PVC or ABS cement.
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 instruc-
tions below, or the trim out section of this
manual on page 9.
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.

ELECTRICAL HOOKUP
Electrical hookups for the OSAA are made
to a junction box located underneath the case on
the bottom left hand front. The light ballasts for
the case are located under the rear sill behind a
removable access cover as shown below.
For case-to-case wiring, run “green-
field”, or other conduit, between junction
boxes. When connecting to the junction box
field connections should be made on the
right hand side of the box to allow more room
inside for wire connecting.

AND
DEFROST TEMP CONTROL
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 thermo-
stat and the temperature control thermostat
are located under the rear sill behind an easily
removable cover, as shown in diagram 2.

AND
AIR FLOW PRODUCT LOADING
Cases have been designed to provide maxi-
mum 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.
Overloading will cause malfunction and the
loss of proper temperature levels, particular-
ly when discharge and return air sections are
covered. Please keep products within the
load limit lines shown on the diagram.

AND
USE MAINTENANCE
CASE CLEANING
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 fas-
teners are used.
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-to-
clean 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.

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. We 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 non-
glare 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
2
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 spec-
ified. 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
