Installation
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.
Exterior Loading
These models have not been structurally designed to
support 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.

Q3-DV Lifting and Transport
Instructions
1. The Q3-DV can be lifted by a forklift at typical lift-
ing points.
2. Ensure lower body panels are removed before
lifting with a forklift. Serious damage will occur if
the body panels are not removed. (Shipped loose
from factory)
3. Make sure that fork spacing and width will not
damage drain or come in contact with piping, or
electrical lines
4. Be sure that the forks are long enough to sup-
port beyond the center of the case but not dam-
age near components. Check for proper balance
before moving. A minimum fork length of 36” is
recommended for 68” wide cases
Installation (cont’d)
5. The Q3-DV merchandiser can be raised at one
end underneath the deck with a forklift or J-Bar if
forklift is not accesible to allow the placement of
rollers or dollies.
6. Evenly support the entire base structure on rollers
or dollies before attempting to move. Each Base
Leg must have its own dollie to properly support
the case.
WARNING
Improper placement of forks may damage
drainage piping. Use a spotter when placing
forks. Make sure that piping will not be dam-
aged. Use J-Bars or Jacks if forks cannot be
used safely
Lifting Points are typical and dependent upon size of
case and refrigeration application, drainage configu-
rations will call for altercations in Lifting Zones.
Below are the following drainage configurations and
lifting should be altered to the expected model.

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 floor 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 flood rim of
the floor 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 non-absorbent insulation
material such as Armstrong’s Armaflex.
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
specified on the customer order. Check the serial plate on
the case for information.
Piping
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.
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 Q3-DV technical data sheet for the appropriate
settings for your merchandiser. Maintain these parameters
to achieve near constant product temperatures. Product
temperature should be measured first thing in the morning,
after having been refrigerated overnight. For all multiplexing,
defrost should be time terminated. Defrost times should be
as directed in the Q3-DV 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. Unscrew the rear panels with
Phillips screwdriver.
Electronic Expansion Valve (Optional)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and
controller manufacturers 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.

CASE MUST BE GROUNDED
NOTE: Refer to label affixed to case to determine the actual
configuration as checked in the “TYPE INSTALLED”
boxes.
Electrical Circuit Identification
Standard lighting for all models will be full length fluorescent
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.
The receptacle that is provided on the exterior back of these
models is intended for computerized scales with a five amp
maximum load, not for large motors or other high wattage
appliances. It should be wired to a dedicated circuit.
NOTE: The total case electrical draw must not exceed 30 Amps
ampacity at 115V in one connected lineup.
Electrical Service Receptacles (When Applicable)
The receptacles located on the exterior of the merchandiser
are intended for scales and lighted displays. They are not
intended nor suitable for large motors or other external
appliances.
BEFORE SERVICING

POWER AT THE MAIN DISCONNECT
WHEN SERVICING OR REPLACING ANY
ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heaters
Thermostats, and Lights.
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
specified. 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.
LED Driver Location
Drivers are located within the access panel that runs the
length of the rear of the case.
