Location
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature and
humidity are maintained at or below 75°F and 55% relative
humidity. DO NOT allow air conditioning, electric fans, ovens,
open doors or windows (etc.) to create air currents around
the merchandiser, as this will impair its correct operation.
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.
Uncrating the Stand
Place the xture as close to its permanent position as
possible. Keep in place, attached case until ready to set/bolt
to adjoining case.
Tighten Glass Screws
Tighten screws along clamshell located on the underside
of glass before placing unit into operation.
Exterior Loading
These models have not been structurally designed to
support excessive external loading. Do not walk on their
tops; This could cause serious personal injury and damage
to the xture.
Setting and Joining
The sectional construction of these models enable them to be
joined in line to give the effect of one continuous display.
An Alignment pin kit is supplied with every case and must
be used in alignment.
Leveling
IMPORTANT! IT IS IMPERATIVE THAT CASES BE
LEVELED FROM FRONT TO BACK AND SIDE TO SIDE
PRIOR TO JOINING. A LEVEL CASE IS NECESSARY
TO INSURE PROPER OPERATION, WATER DRAINAGE,
GLASS ALIGNMENT, AND OPERATION OF THE HINGES
SUPPORTING THE GLASS. LEVELING THE CASE
CORRECTLY WILL SOLVE ALL HINGE OPERATION
AND GLASS PROBLEMS.
Cut and Plan Views
Installation
NOTE: A. To avoid removing concrete ooring, begin lineup
leveling from the highest point of the store oor.
B. When wedges are involved in a lineup, set them rst.
All cases were leveled and joined prior to shipment to
insure the closest possible t when cases are joined in
the eld. When joining, use a carpenters level and adjust
legs accordingly. The legs on the Q1-DC are adjustable
and do not require shims. Simply screw the leg up or down
to adjust height.
1. Using case blueprints, measure off and mark on the
oor the exact dimensions of where the cases will
sit. Snap chalk line for front and back positions of
base rail or pedestal. Mark the location of each joint
front and back. Find the highest point throughout the
lineup. FLOORS ARE NORMALLY NOT LEVEL!
Determine the highest point of the oor; cases will
be set off this point. All cases in the entire lineup
must be brought up to the highest level of the case
sitting at the highest point in the lineup. This may be
done a few different ways.
a) Walk the oor looking for any mounds or dips.
b) Use a string level.
c) Use a transit.
If a wedge is used in the middle of a lineup, the
wedge must be set on the highest point on the oor
FIRST, with the rest if the lineup being leveled from
it. The Q1-DC case has adjustable legs to allow for
leveling.
2. Set rst case over the highest part of the oor and
3
adjust legs so that case is level. Remove side and
back leg braces after case is set and joined.
3. Set second case within one foot (1’) of the rst case,
and remove leg skids. Keep the supports along the
length of the case and far end of case. Level case to
the rst using the instructions in step one.
4. Apply masking tape 1/8” in from end of case on
inside and outside rear mullion and body work on
both cases to be joined.
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.
Do not use bolts to pull cases together.

entire shaded area.
DO NOT USE PERMAGUM!
6. Slide second case up to rst case snugly. Then level
second case to the rst case so glass front, bumper
and top are ush.
7. To compress butyl at joint, use two Jurgenson
wood clamps. Make sure case is level from front to
back and side to side on inside bulkheads at joint.
8. Attach sections together via the bolts pictured in the
illustration below.
9. Apply bead of butyl to top of bulkheads
and slip on stainless steel bulkhead cap. Also apply
silicone to seam between overhead light tubes.
10. Use nger to smooth silicone as thin as possible at
masking tape on inside and outside of rear mullion
(apply additional silicone if necessary). Remove
tape applied on line #4.
11. Remove front, back and end shipping braces.
Q1-DC Refrigerated Wedges and Standard Cases
Line-up taper pins and line-up plates with holes on adjoining
case. Bolting is located at the rear of the case, behind the
air discharge wall, and behind the front body panel. The
cases are bolted together in front by means of a bracket
located behind the front panel. Remove the front panel by
unscrewing these bottom screws.

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 xture.
A 1-1/2” P-TRAP and threaded adapter are supplied with
each xture. The P-TRAP must be installed to prevent air
leakage and insect entrance into the xture.
NOTE: PVC-DWV solvent cement is recommended. Follow the
Hussmann’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 oor drains should be at least 14”
off the center of the case to allow use of the P-TRAP
pipe section. Never use two water seals in series in
any one line. Double P-TRAPS in series will cause a
lock and prevent draining.
3. Always provide as much down hill slope (“fall”) as
possible; 1/8” per foot is the preferred minimum.
PVC pipe, when used, must be supported to
maintain the 1/8” pitch and to prevent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to provide the “fall” necessary for
good drainage.
5. Provide a suitable air break between the ood rim of
the oor drain and outlet of condensate drain. 1” is
ideal.
6. Prevent condensate drains from 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 Armstrong’s Armaex.
b. Where condensate drains are located in dead
air spaces (between refrigerators or between a
refrigerator and a wall), provide means to prevent
freezing. The water seal should be insulated to
prevent condensation.
Refrigeration
Refrigerant Type
The standard refrigerant will be R-22 unless otherwise
specied on the customer order. Check the serial plate on
the case for information.
Piping
The refrigerant line outlets are located under the case.
Locate rst 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 1/2” (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. Install P-TRAPS
(oil traps) at the base of all suction line vertical 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 Q1-DC technical data sheet for the appropriate
settings for your merchandiser. Maintain these parameters
to achieve near constant product temperatures. Product
temperature should rst be measured in the morning, after
having been refrigerated overnight. For all multiplexing,
defrost should be time terminated. Defrost length and
frequency should be as directed in the Q1-DC technical
data sheet. The number of defrosts per day should never
change. The duration of the defrost cycle may be adjusted
to meet conditions present at your location.
Access to TEV Valves and Drain Lines
MECHANICAL - Remove product from case. Remove
pans. TX valve (mechanical only) and drain are located
under the pans within the case.
ELECTRONIC - The electronic expansion valve master and
slave cylinder(s) are located within the electrical access
panel(s) in the rear of case. Rear panels lift up and out.
NOTE: Duplex receptacles must be detached before removing
rear panels.

ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heaters
Thermostats, and Lights.
Refrigeration (Cont'd)
Q1-DC-0508
Electronic Expansion Valve (Optional)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and
controller Hussmann’s information 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.
Expansion Valve Adjustment
Expansion valves must be adjusted to fully feed the
evaporator. Before attempting any adjustments, make
sure the evaporator is either clear or very lightly covered
with frost, and that the xture 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 pressure 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 from the temperature measured in step No. 3.
5. The difference is superheat.
6. Set the superheat for 5°F - 7°F.
Thermostat Location
Thermostats are located in the electrical section; behind
the rear panel, on the right-hand side of the case (facing
the back of the case).
Wiring Color Code
CASE MUST BE GROUNDED
NOTE: Refer to label afxed to case to determine the actual
conguration as checked in the “TYPE INSTALLED”
boxes.
Electrical Circuit Identication
Standard lighting for all models will be full length uorescent
lamps located within the case at the top. The switch
controlling the lights, the plug provided for digital scale,
and the thermometer are located at the rear of the case
mullion.
Electrical
The receptacle that is provided on the exterior back of these
models is intended for computerized scales with a ve amp
maximum load, not for large motors or other high wattage
appliances. It should be wired to a dedicated circuit.
Field Wiring and Serial Plate Amperage
Field Wiring must be sized for component amperes printed
on the serial plate. Actual ampere draw may be less than
specied. Field wiring from the refrigeration control panel to
the merchandisers is required for refrigeration thermostats.
Case amperes are listed on the wiring diagram, but always
check the serial plate.
Ballast Location
Ballasts are located within the access panel that runs the
length of the rear of the case.

Finishing Touches
Bumper Installation Tips
1. Start to attach the bumper at one end of the lineup,
preferably on a straight case.
2. Push the end of the bumper into the bumper
channel rmly. This may be difcult if bumper is cold.
3. Bend the bumper backwards to open and guide it
forward onto the bumper channel.
4. An inside bumper miter must be cut on wedges.
5. Loose ends on miters must be anchored with
screws on the bottom edge.
6. The top and bottom edges of the bumper must be
rmly seated into the retainer by applying with a
rubber mallet (not by hand).
7. The bumper should be struck by the mallet at a
slight angle that forces the bumper back into itself
to prevent stretching. The installation can be made
easier by applying a parafn block to the retainer
grooves.

Installing Splashguard
After merchandisers have been leveled and joined, and
all drip piping, electrical and refrigeration work has been
completed, install the splashguards. Splashguards may
be sealed to the oor using a vinyl cove base trim. The
size of trim needed will depend on how much the oor is
out of level.
NOTE: The splashguard must be removable to allow access to
components behind it.
1. Remove all dirt, wax, debris, etc. from the area of
the splashguard to ensure a secure adhesion.
2. Apply a good contact cement to the trim, allowing a
proper dry time.
3. Install trim to the splashguard so that it is ush with
the oor.
User Information
Stocking
Improper temperature and lighting will cause serious
product 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 display, the temperature
of the product 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 avoid damaging
temperature rise to the product. Product should be
at proper temperature.
2. Keep the air in and around the case area free
of foreign gasses and fumes or food will rapidly
deteriorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of this
manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they
are operating at the proper temperature. Allow
merchandiser to operate a minimum of six (6) hours
before stocking with any product.
5. When stocking, never allow the product to extend
beyond the recommended load limit. Air discharge
and return air ow must be unobstructed at all times
to provide proper refrigeration.
6. There are vents located at the base of the front
of the glass, just above the front rail. These vents
supply a continuous, gentle ow of air across the
front glass which inhibits condensation. Do not
place any signs or other restrictive objects on the
front of the refrigerator that will block these vents.

CLEANING PRECAUTIONS
When cleaning:
• Do not use high pressure water hoses
• Do not introduce water faster than waste outlet can drain
• NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL
BASE (these will dissolve the butyl sealants) or an AMMONIA BASE
(this will corrode the copper componets of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
• DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY
• DO NOT USE ABRASIVES OR STEEL WOOL PADS AS THESE
WILL MAR THE FINISH
User Information (Cont'd)
Q1-DC-0508
7. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
8. Avoid the use of supplemental ood or spot lighting.
Display light intensity has been designed for
maximum visibility and product life at the factory.
The use of higher output uorescent lamps (H.O.
and V.H.O.), will shorten the shelf life of the product.
9. In the Deli, Meat and Fish cases, completely cover
the product each night with a clean damp cloth or
butcher paper (never use plastic, as it does not
allow for proper circulation). Make sure the cloth or
paper is in direct contact with the product.
10. Turn and rotate the meat fairly often. The blood
which gives the pink color works its way downward
with time.
11. Cold coils remove heat and moisture from the
case and deposit this as frost onto the coil. Thus,
a defrost is required. Our humidity system induces
moisture into the case and helps slow down the
dehydration process. The only other moisture within
the case is that in the product itself. A single level of
meat will dry out faster than a fully loaded case of
3-4 levels of meat.
Important Steps
1. Do not set temperature too cold, as this causes
product dehydration. Product Temperature:
33°-35°F! Set thermostat to cut in at 28°F discharge
air. Meat holding box: 32°F. Meat prep room: 55°F.
Meat bloom box: 36°F. Process the meat to enter
case at 40°F or below. Product deterioration is very
rapid above 40°F.
2. Temperature control 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 devices of any kind, as these
allow temperature swings causing dehydration and
excessive energy consumption.
3. Product should be worked and rotated on a regular
basis, not to exceed a 4 hour period.
4. At night, turn off case lights and cover 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 day - so that it is cool
and moist when covering the product.
5. Discharge air temperature should be approximately
26°F, with between 150-200 FPM air velocity. Do not
display product directly within the air discharge.
6. Clean humidity system a minimum of every 90 days
for proper system operation.
Case Cleaning
Long life and satisfactory performance of any equipment
are dependent upon the care given to it. To insure long
life, proper sanitation and minimum maintenance costs,
the refrigerator should be thoroughly cleaned frequently.
SHUT OFF FAN DURING CLEANING PROCESS. It can
be unplugged within the case, or shut off entire case at
the source. The interior bottom may be cleaned with any
domestic soap or detergent based cleaners. Sanitizing
solutions will not harm the interior bottom, however,
these solutions should always be used according to the
Hussmann’s directions. It is essential to establish and
regulate cleaning procedures. This will minimize bacteria
causing discoloration which leads to degraded product
appearance and signicantly shortening product shelf
life.
Soap and hot water are not enough to kill this bacteria. A
sanitizing solution must be included with each cleaning
process to eliminate this bacteria.
1. Scrub thoroughly, cleaning all surfaces, with soap
and hot water.
2. Rinse with hot water, but do not ood.
3. Apply the sanitizing solution according to
Hussmann’s directions.
4. Rinse thoroughly.
5. Dry completely before resuming operation.
Cleaning Glass and Mirrors
Only use a soft cloth and mild glass cleaner for cleaning
any glass or mirrored components. Be sure to rinse and/or
dry completely.
Never use hot water on cold glass surfaces! It may
shatter and cause serious injury! Allow glass surfaces
to warm rst.

Rev. 0508
User Information (Cont'd)
Non-Glare Glass
The high optical clarity of this glass is possible due to
special coatings on the glass surface itself. To preserve this
coating and the optical clarity, keep the glass clean.
Water is the only solution recommended for use in cleaning
non-glare glass. The damage to the glass from improper,
caustic solutions is irreparable.
In addition to cleaning the glass with the recommended
product, there are precautions that should be taken when
working and cleaning the inside of the case.
• When cleaning the inside of the cases, we
recommend that the glass be fully opened and
covered to prevent solutions from splashing onto the
glass and ruining the coating on the inside.
Plexiglass and Acrylic Care
Improper cleaning not only accelerates the cleaning cycle
but also degrades the quality of this surface. Normal daily
bufng motions can generated static cling attracting dust
to the surface. Incorrect cleaning agents or cleaning cloths
can cause micro scratching of the surface, causing the
plastic to haze over time.
Cleaning
Hussmann recommends using a clean damp chamois, or a
paper towel marked as “dust and abrasive free” with 210®
Plastic Cleaner and Polish available by calling Sumner
Labs at 1-800-542-8656. Hard, rough cloths or paper towels
will scratch the acrylic and should not be used.
Antistatic Coatings
The 210® has proven to be very effective in not only
cleaning and polishing the Plexiglass surface, but also
providing antistatic and anti-fog capabilities. This product
also seals pores and provides a protective coating.
