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 as self‐contained models as well
as a remote option. 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
Plumbing and Construction
Code ha ving jurisdiction.

Do not Push, Pull, Adjust or Manipulate the Mobile
Produce Case by any glass component.
Doing so will result in:
•Severe damage to such components
•Glass or Acrylic breakage
•Serious injury
Never stand on the Mobile Produce Case deck for
any reason. These surfaces are not steps and are not
designed to support such loads.
Doing so will result in:
•Damage to case
•Serious injury to user
Moving Mobile Produce Case
Refer to shaded areas of description below for proper
grasp locations im movement of case which will not dam‐
age Mobile Produce Case or components.
Installation
Location
The Mobile Produce Case display has been designed for
use only in air conditioned stores where temperature and
humidity are maintained either 75°F ambient and 55% RH.
When selecting the location for placement of this
case, avoid the following conditions:
Excessive air movement
• Doors
•Air‐conditioned vents
•Otherairsources
Excessive heat
• Windows
•Sun
• Flood lamps 8 feet or less from the product
•Otherheatsources
Skid Removal
Unstrap case from skid and roll case offto move near plac‐
ing location
Note:
Cases are manufactured and shipped to stores with
casters installed on the base frame to make the job of
moving cases easier for everyone involved with the
manufacturing, shipping and installation process.
Casters not only speed up the process, but they also
reduce the chance of damage from raising and lowering
cases with ”J” bars to place them on dollies, skates or roll‐
ers. In most situations, one or two persons can move the
case with ease.

Case Refrigeration
Operation
Each self‐contained model is equipped with its own condensing unit located beneath the display area. The unit will be
charged per nameplate refrigerant and shipped from the factory with all service valves open, completely ready for opera‐
tion when electrical power has been connected.
The self‐contained refrigeration system is thermostatically regulated. The thermostat in the case is set to a certain cut
out point in which the case will refrigerate until that cut out point is reached and will cease to refrigerate the case by the
thermostat.

1. The Controller controls refrigeration temperature. This is factory installed in the control panel. Adjust
this control to maintain the discharge air temperature shown. Measure discharge air temperatures at the center
of the honeycomb. The defrost setting is factory set as shown above.
Condensate Pan Setup
Setup:
There is one condensate evaporator pan on this unit for self-contained models. The drain pipe from the case feed into the
condensate pan, once water levels are high enough in the condensate pan the float switch level is triggered which will then
trigger the heater to raise temperature therefore evaporating the water into the case airstream.
