Product temperature should always be maintained at a
constant and proper temperature. This means that from
the time the product is received, through storage, preparation and display, the temperature of the product must
be controlled to maximize life of the product.
UNCRA TING THE ST AND
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid. The fixture can now be lifted off the
crate skid. Lift only at base of stand!
EXTERIOR LOADING
These models have not been structurally designed to sup-
port excessive external loading. Do not walk on their
tops; This could cause serious personal injury and damage to the fixture.
AVOID REMOVING CONCRETE
All cases were leveled and joined prior to shipment to
ensure closest possible fit when cases are joined in the
field. To avoid removing concrete flooring, begin
lineup at highest point of store floor.
LEVELING
IMPORTANT! It is imperative that the case
be leveled from front to back and side to side
prior to joining. A level case is necessary to
insure proper operation.
JOINT TRIM
After the case has been leveled and joined, and refrigeration, electrical, and waste piping work completed, install
the splashguards. Fasten along the top edge, or center, with
#10 X 3/8" sheet metal screws.
DO NOT S EAL JOINT TRIM TO FLOOR!

LOCATION
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperatur e and
humidity are maintained at or below 75°F and 55% relative humidity . DO NO T allow air conditioning, electric fans,
open doors or windows (etc.) to create air currents ar ound
the merchandiser, as this will impair its correct operation.
Plumbing
WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the fixture.
A 1-1/2" P-trap and threaded adapter are supplied with
each fixture. The P-trap must be installed to prevent air
leakage and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.

INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can seriously interfere with the operation of this refrigerator,
and result in costly maintenance and product losses. Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section. Nev er use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.
3. Always pr ovide as much down hill slope (“fall”) as
possible; 1/8" per foot is the pr eferred minimum.
PVC pipe, when used, m ust be supported to maintain the 1/8" pitch and to prev ent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to pr ovide the “fall” necessary for
good drainage.
5. Provide a suitable air break betw een the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.
6. Prevent condensate drains fr om freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstr ong’ s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or betw een a
refrigerator and a wall), pr ovide means to pre vent
freezing. The water seal should be insulated to
prevent condensation.
Refrigeration
REFRIGERANT TYPE
The standard refrigerant will be R-22 unless otherwise
specified on the customer order. Check the serial plate
on the case for information.
PIPING - Remote Cases Only
The refrigerant line outlets are located under the case.
Locate first the electrical box, the outlets are then on the
same side of the case but at the opposite end. Insulate
suction lines to prevent condensation drippage.
REFRIGERATION LINES
LIQUID SUCTION
3/8" O.D. 5/8" O.D.
NOTE: The standard coil is piped at 5/8" (suction); however,
the store tie-in may vary depending on the number of
coils and the draw the case has. Depending on the case
setup, the connecting point in the store may be
5
/8", 7/8", or 11/8". Refer to the particular case you are
hooking up.
Refrigerant lines should be sized as shown on the refrigeration legend furnished by the store.
P-traps (oil traps) at the base of all suction line ver-
Install
tical risers.
Pressure drop can rob the system of capacity. To keep the
pressure drop to a minimum, keep refrigerant line run as
short as possible, using the minimum number of elbows.
Where elbows are required, use long radius elbows only.
CONTROL SETTINGS
See the “Case Specs” section of this guidebook for the
appropriate settings for y our merchandiser . Maintain these
parameters to achieve near constant product temperatures. Pr oduct temperature should be measured first thing
in the morning, after having been refrigerated overnight.
For all multiplexing, defrost should be time terminated.
Loadmaster valves are not recommended. Defrost times
should be as follows: OFF CYCLE - Three times daily for
46 minutes. The number of defr osts per day and the duration of the defrost cycle may be adjusted to meet conditions present at your location.
ACCESS TO TX VALVES & DRAIN LINES
MECHANICAL - Remove the product fr om the bottom deck
pan. Remove pan. Remov e refrigeration and drain access panels (labeled). TX valve (mechanical only) and drain are located under each access panel at end of the case.
ELECTRONIC (Remote Only) - The Electronic Expansion valve
controller is located within the electrical access panel(s).
ELECTRONIC EXPANSION VALVE (Remote Only)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and controller manufacturers inf ormation sheet. Sensors for electronic expansion valves will be installed on the coil inlet,
coil outlet, and in the discharge air. (Some supermarkets
require a 4th sensor in the return air). Case controllers
will be located in the electrical raceway or under the case
THERMOSTATIC EXPANSION VALVE LOCATION
This device is located on the same side as the refrigeration stub. A Sporlan balanced port expansion valve model
is furnished as standard equipment, unless otherwise specified by customer.

EXP ANSION VAL VE ADJUSTMENT
Expansion valves must be adjusted to fully feed the e vaporator. Before attempting any adjustments, make sure the
evaporator is either clear or very lightly cov ered with frost,
and that the fixture is within 10°F of its expected operating temperature.
MEASURING THE OPERATING SUPERHEAT
1 . Determine the suction pressure with an accurate
pressure gauge at the evaporator outlet.
2 . From a refrigerant pr essure temperature chart,
determine the saturation temperature at the
observed suction pressure.
3 . Measure the temperature of the suction gas at the
thermostatic remote bulb location.
4 . Subtract the saturation temperature obtained in step
No. 2 fr om the temperature measured in step No. 3.
3 . The difference is superheat.
5 . Set the superheat for 5°F - 7°F.
NOTE: Slow air picks up more humidity from coil and ice.
T-STAT LOCATION
T-Stats are located within the electrical racewa y. at the front
of the case.

User Information
STOCKING
Improper temperature and lighting will cause serious pr oduct loss. Discoloration, dehydration and spoilage can be
controlled with proper use of the equipment and handling
of product. Product temperature should always be maintained at a constant and proper temperature. This means
that from the time the product is received, through storage, preparation and displa y, the temperature of the pr oduct must be controlled to maximize life of the product.
Hussmann cases were not designed to “heat up” or “cool
down” product—but rather to maintain an item’s proper
temperature for maximum shelf life. To achieve the protection required always:
1. Minimize processing time to a void damaging temperature rise to the product. Product should be at
proper temperature.
2. K eep the air in and around the case area fr ee of
foreign gasses and fumes or food will rapidl y deteriorate.
3. Maintain the display mer chandisers temperature
controls as outlined in the refrigerator section of
this manual.
4. Do not place any product into these r efrigerators
until all controls ha ve been adjusted and they are
operating at the proper temperature. Allow mer chandiser to operate a minimum of 6 hours before
stocking with any product.
5. When stocking, nev er allow the product to extend
beyond the recommended load limit. Air dis-
charge and return air flue must be unobstructed at all times to pro vide proper refrigeration.
6. There are v ents located at the base of the front of
the glass, just abov e the front rail. These vents supply
a continuous, gentle flow of air acr oss the front glass
which inhibits condensation. Do not place any
signs or other restrictive objects on the fr ont
of the refrigerator that will block these v ents.
7. Avoid the use of supplemental flood or spot lighting.
Display light intensity has been designed for maxi-
mum visibility and product life at the factory . The use
of higher output fluorescent lamps (H.O . and V.H.O .),
will shorten the shelf life of the product.
IMPORTANT STEPS
1. Do not set temperature too cold, as this causes
product deh ydration. Product T emperature:
33°–35°!
Set thermostat to cut in at 28° discharge air . Meat
holding box: 32°. Meat prep room: 55°. Meat bloom
box: 36°.
Process the meat to enter case at 40° or below .
Product deterioration is very rapid abov e 40°.
2. Temperature control in service sections should be
by means of a T-Stat and Suction Stop Solenoid at
each case. Do not use EPR valves, Liquid Line
Solenoids or electronic control de vices of any kind,
as these allow temperature swings causing deh ydration and excessive energy consumption.
3. Product should be work ed and rotated on a regular
basis, not to exceed a 4-hour period.
4. At night, turn off case lights and cov er the product
with a damp (not wet) cloth similar to cheese cloth
(etc.). This should be washed out in the morning and
kept in a walk-in box during the da y—so that it is
cool and moist when covering the product.
5. Discharge air temperature should be appro ximately
26°F, with between 150-200 FPM air v elocity . Do not
display pr oduct directly within the air discharge.
CASE CLEANING
Long life and satisfactory performance of any equipment
are dependent upon the care giv en to it. To insure long life,
proper sanitation and minimum maintenance costs, the
refrigerator should be thoroughl y cleaned frequently. It is
essential to establish and regulate cleaning procedur es. This
will minimize bacteria causing discoloration which leads
to degraded product appearance and significantly shortening product shelf life.
SHUT OFF FAN DURING CLEANING PROCESS. It can
be unplugged within the case, or shut off case at the source.
The interior bottom may be cleaned with any domestic
soap or detergent based cleaners.
The use of hoses and sage machines to clean the inside of
the cases is recommended and is an excellent wa y to clean
the coil fins and hard to reach corners of the interior of
the cases. Be sure to observe the warnings below when
cleaning the case.
Sanitizing solutions will not harm the interior bottom,
howev er, these solutions should al ways be used accor ding
to the manufacturer’s directions and should not contain
