Description: Refrigerated vertical Deli/Bakery Merchandiser
Shipping Damage: All equipment should be thoroughly examined for shipping damage before and
during unloading. This equipment has been carefully inspected at our factory and the carrier has
assumed responsibility for safe arrival. If damaged, either apparent or concealed, claim must be
made to the carrier Immediately.
Apparent Loss or Damage: If there is an obvious loss or damage, it must be noted on the freight bill
or express receipt and signed by the carrier’s agent; otherwise, carrier may refuse claim. The carrier
will supply necessary claim forms.
Concealed Loss or Damage: When loss or damage is not apparent until after all equipment is
uncrated, a claim for concealed damage is made. Make request in writing to carrier for inspection
within 15 days, and retain all packaging. The carrier will supply inspection report and required claim
forms.
Shortages: Check your shipment for any possible shortages of material. If a shortage should exist
and is found to be the responsibility of Hussmann Chino, notify Hussmann Chino. If such a shortage
involves the carrier, notify the carrier immediately, and request an inspection. Hussmann Chino will
acknowledge shortages within ten days from receipt of equipment.
Hussmann Chino Product Control: The serial number and shipping date of all equipment has been
recordedinHussmann’slesforwarrantyandreplacementpartpurposes.Allcorrespondence
pertaining to warranty or parts ordering must include the serial number of each piece of equipment
involved, in order to provide the customer with the correct parts.
Location/Store Conditions: The Q3-DV refrigerated merchandiser has been designed for use only
in air conditioned stores where temperature and humidity are maintained at 80°F and 55% relative
humidity or 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.
This equipment is to be installed
to comply with the applicable
NEC, Federal, State , and Local
Plumbing and Construction
Code having jurisdiction.

Snapping Chalk Lines
Preparepermanentpositioningbymarkingoors
with Chalk snap lines where cases are to be
located. Chalk lines are to run along the base or
legs of cases.

Placement
Important: See lifting instructions to properly lift
case when being placed on dollies or permanent
location. (See page 8 for Lifting Instructions.)
First remove Blocks and L Brackets around the
case from pallet.
Remove Block
and L bracket
Proceedbysettingforkliftsunderspeciedloca-
tions as instructed in the Lifting Instructions
(pg. 8.) Be careful not to damage drains or near
components when placing forks underneath
case. A spotter is mandatory to ensure no dam-
age is caused to the case. Lift case and replace
with dollies, place near or in permanent location.

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
2. Ensure lower body panels are removed be-
fore lifting with a forklift. Serious damage will
occur if the body panels are not removed.
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
support beyond the center of the case but not
damage 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 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.
Lifting Points are typical and dependent upon
size of case and refrigeration application, drain-
agecongurationswillcallforaltercationsin

Leveler Adjustment
Position the case at the highest point. Set a long
magnetized level (4ft [1220 mm] or more) on
either underneath the deck or on top of the case.
Ensure to level case from front to back and side
to side.
Level
(4 ft[1220mm])
Shim The Case
Use shims at each corner of the case to level
out any discrepancies in order to optimize case
performance and proper drainage.
Note: Shims are not Factory supplied. Contractor
should carry available components. Metal Shims
are recommended for use to eliminate any
deterioration from shims over time.
Note:Toavoidremovingconcreteooring,begin
line up levelling from the Highest point of the

NOTICE
Longer length cases may require shims
along the center portion of the case to
maintain proper case performance and
drainage.

Refrigeration
Refrigerant
The correct type of refrigerant will be stamped
on each merchandiser’s serial plate. The case
refrigeration piping is pressurized with a nitrogen
holding charge, leak tested and factory sealed.
Before making refrigeration hookups, depress
universal line valve (Shraeder Valve) to ensure
that coils have maintained pressure during ship-
ment. In the case pressure was not maintained
contact your Hussmann Service Tech for further
assistance.
Serial Plate Location
CAUTION
Refrigeration lines are under pressure.
Refrigerant must be recovered before
attempting to make any connections.
Refrigerant piping
The refrigerant line connections are at the right
hand end of the case (as viewed from the front)
beneath the display pans. The merchandiser will
beforehand ensure an earlier cut hole through
the pod to exit the merchandiser for the refrigera-
tion lines. After connections have been made,
make certain to seal this outlet thoroughly if not
sealed at factory already. Seal both the inside
and outside. We recommend using an expanding
polyurethane foam insulation.
Line Sizing
Refrigerant should be sized as shown on the
refrigeration legend that is furnished for the store
or according to the ASHRAE guidelines
Oil Traps
P-traps (oil traps) must be installed at the base
of all suction line vertical risers.
It is the contractor's responsibility to install
case(s) according to local construction and
health codes.

Merchandiser Electrical Data
Technical data sheets are shipped with this
manual. The data sheets provide merchandiser
electrical data. Refer to the technical data sheets
and merchandiser serial plate for electrical
information.
Electrical Connections
All wiring must be in compliance with NEC and
local codes. All electrical connections including
both supply circuits are to be made in the electri-
cal J-Box.
ALWAYS CHECK THE SERIAL PLATE FOR
COMPONENT AMPERES
Field Wiring
Field wiring must be sized for component am-
peres stamped on the serial plate (refer to pg 16
for location). Actual ampere draw may be less
thanspecied.
Identication of Wiring
Leadsforallelectricalcircuitsareidentiedby
colored plastic bands. These bands correspond
to the color code sticker (shown below) located
inside the merchandiser’s wireway cover.
WARNING
--LOCK OUT/ TAG OUT--
To avoid serious injury or death from electrical
shock, always disconnect the electrical power
at the main disconnect when servicing or
replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
