LOCATION
The refrigerated merchandisers have been designed
foruseonlyinairconditionedstoreswheretemperature
and humidity are maintained at or below 75°F and
55%relative humidity. DO NOTallow airconditioning,
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 fixture 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
Thesemodels 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 fixture.
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
alignment problems.
NOTE:A. To avoid removing concrete flooring, begin lineup leveling
from the highest point of the store floor.
B. When wedges are involved in a lineup, set them first.
Allcaseswereleveledand joined prior to shipment to
insure the closest possible fit when cases are joined
in the field. When joining, use a carpenters level and
adjust legs accordingly. The legs on the Q3-DC are
adjustable and do not require shims. Simply screw
the leg up or down to adjust height.

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.
A1-1/2”P-trap andthreaded adapterare suppliedwith
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 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. Neverusepipeforcondensate drains smaller
thanthenominaldiameterof the pipe or P-trap
suppliedwiththecase.
2. Whenconnectingcondensatedrains,the P-
trapmustbeusedas part of the condensate
draintopreventairleakage or insect entrance.
Storeplumbingsystemfloor drains should be at
least14”offthe center of the case to allow use
oftheP-trappipesection. Never use two water
sealsinseriesinany one line. Double P-traps in
serieswillcausealock and prevent draining.
3. Alwaysprovideasmuchdown hill slope (“fall”)
aspossible;1/8”perfoot is the preferred
minimum.PVCpipe,whenused, must be sup-
portedtomaintainthe1/8” pitch and to prevent
warping.
4. Avoidlong runs of condensate drains. Long
runsmakeitimpossibleto provide the “fall”
necessaryforgooddrainage.
5. Provideasuitableairbreak between the flood
rimofthefloordrain and outlet of condensate
drain.1”isideal.
6. Preventcondensatedrainsfromfreezing:
a.Do not install condensate drains in contact
withnon-insulatedsuctionlines.Suction lines
shouldbeinsulatedwith a nonabsorbent
insulationmaterialsuchasArmstrong’s
Armaflex.
b.Where condensate drains are located in dead
airspaces(betweenrefrigeratorsor between
arefrigeratorandawall), provide means to
preventfreezing.The water seal should be
insulatedtopreventcondensation.

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
DURINGCLEANINGPROCESS.It canbe unplugged
within the case, or shut off entire case at the source.
Theinterior bottommaybe cleanedwith 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 significantly

4. Rinsethoroughly.
5. Drycompletelybeforeresumingoperation.
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 first.
CLEANING PRECA UTIONS
WHEN CLEANING:
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.
Do Not Use high pressure hoses
Do Not Introduce water faster than waste

Never Usea Cleaningor SanitizingSolution
that has an OIL BASE (these will dissolve
the sealants) or AMMONIA BASE
(this will corrode the copper components
of the case)
TO PRESERVE FINISH
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.
Inadditiontocleaningtheglasswiththerecommended
product, there are precautions that should be taken
when working and cleaning the inside of the case.
• Whencleaningtheinsideof the cases, we
recommendthattheglassbe fully opened and
coveredtopreventsolutionsfrom splashing
onto theglassandruiningthe 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 buffing motions can generated static
clingattractingdusttothe surface. Incorrect cleaning
agentsorcleaningclothscancausemicroscratching
of the surface, causing the plastic to haze over
time.
CLEANING
Hussmannrecommendsusingacleandampchamois,
or a paper towel marked as “dust and abrasive free”
with 210®Plastic Cleaner and Polish available by
callingSumnerLabsat1-800-542-8656.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
alsoproviding antistaticandanti-fog capabilities. This
product also seals pores and provides a protective
coating.
