General Information
Description: Mobile Produce Case model series are Multi‐deck, spot merchandisers designed for non‐critical temperature
applications such as: Non Hazardous Produce. They are available in remote as well as self‐contained models. Each self‐
contained model will have it’s own condensing unit, factory installed beneath the display area of the case ready for
operationwhen electrical service is connected.
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.
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.
Location/Store Conditions: The refrigerated merchandisers have been designed for use only in air conditioned stores
where temperature and humidity are maintained either 75°F ambient and 55% RH . 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.
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 files 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.
This equipment is to be installed
to comply with the applicable
NEC, Federal, State ,and Local

underneath the base with a J‐Bar to allow the place‐
ment of rollers or dollies.
2. Evenly support the entire base structure on rollers or
dollies before attempting to move. Each corner and /
or base leg including center structure depending on
length of merchandiser must have its own dollie to
properly support the case.

Setting and Joining
Thesectional construction of these models enable them
to be joined in line to give the effect of one continuous
display.
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 MOST HINGE OPERATION PROBLEMS.
Snapping Chalk Lines
Prepare permanent positioning by marking floors with
Chalk snap lines where cases are to be located. Chalk lines
are to run along the base or legs of cases.

Setting
STEP 1. Using case blueprints, measure off and mark on
the floor 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 floor; 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.
1’
Do not use bolts to pull cases together.
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.

ATTENTION
INSTALLER
STEP 2. Set first case over the highest part of the floor and
adjust legs so that case is level.
STEP 3. Set second case within one foot (1’) of the first
case. Keep the supports along the length of the case and
far end of case. Level case to the first using the instruc‐
tions in step one.

STEP 4. Apply liberal bead of case joint sealant (Silicone)
to first case. Sealant area is shown in illustration. Apply
heavy amount to cover entire shaded area. (pg10)
STEP 5. Slide second case up to first case snugly. Then
level second case to the first case so glass front, bumper
and top are flush.
Installation (cont’d)
STEP 6. 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.
STEP 7. Attach sections together.
STEP 8. Apply bead of butyl to top of bulk heads and slide
on stainless steel bulkhead cap as pictured below. Also ap‐
ply silicone to seam between joints.

Front Body Panel Access
Located in the lower front body panel is an easily acces‐
sible access panel which can be detached by removing the
fastened sccrews which hold the panel in place. Removing
this access panel gains access to some of the merchandis‐
ers electrical components as well as other components to
operatethecase.
Front Body Panel Removal
To further gain access to the entire lower base of the mer‐
chandiser remove the complete lower front body panel
by lifting up from the resting hooks than away from the
merchandiser.

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 shipment. If in
the case pressure was not maintained, contact your Huss‐
mann Service Tech for further assistance.
SERIAL PLATE
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 refrigeration 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 suc‐
tion line vertical risers.
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.

boxes.
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.
