INTRODUCTION
2.0 FUNCTIONAL DESCRIPTION
This technical manual provides information on
the installation, operation, maintenance and
inspection of this unit. A complete parts
breakdown is provided.
This unit is self-contained, automatically
controlled, continuous duty perishable food
storage system. It is designed with the intent
and purpose of storing cold food items. The
operating
temperature
is
automatically
monitored by controls that are factory-set to
1.1 EQUIPMENT DESCRIPTION
maintain a predetermined, adequate condition.
The unit consists of two basic assemblies:
a) Condensing Unit Compartment which
includes the condensing unit, the electrical
control panel with power switch and terminal
box, and a heated condensation evaporator.
b) Storage Compartment which consists of the
insulated clear storage area for perishable food
items requiring a temperature range of 37° to
40°F (3° to 4°C). The clear storage area
includes adjustable shelving.
The unit consists of the following:
Storage compartment: The insulated food
storage compartment is clear storage area.
Included in this area are the adjustable shelves
and cooling coil.
Doors: Access to the storage compartment is
through a hinged-mounted insulated door.
Condensing unit Compartment: This area
contains the condensing unit along with the
necessary controls.
2.1 SYSTEM OPERATION
Evaporator Coil: The evaporator coil is located
in the storage compartment and is responsible
for distributing the cold air associated with the
refrigeration system.
The primary focus for the design of the
refrigerated cabinet is for the safe storage of
food products which require refrigeration.
Considerable engineering attention was placed
on the qualities of function and serviceability.
1.2 EQUIPMENT SUPPLIED
The refrigeration system is a closed loop
system. Unless the system develops a leak,
adding additional refrigerant is not necessary.
The unit is shipped from the factory fully
assembled except the adjustable shelving that
will require positioning on the side racks. The
complete assembly is palletized and crated to
reduce the possibility of damage in shipping
and storage.
3.0 START UP PROCEDURE
The refrigeration system is completely factory-
assembled, pre-charged and ready for
operation. The control has been set to display
temperature in degrees Fahrenheit or degree
Celsius as specified on the original order.
1.3 LEADING PARTICULARS
Refrigerant: 404a
To energize the system, it is only necessary to
locate the power supply cord and connect it to
a proper electrical supply source. Once the
supply cord has been connected to a power
source, the unit can be started by switching the
power control switch to the "ON" position.

OPERATION / CLEANING
4.0 OPERATING PROCEDURE
5.1 CLEANING
Follow appropriate state and local health
(hygiene) regulations regarding all applicable
cleaning and to sanitation requirements for food
service equipment.
The purpose of this mobile refrigerator is to
maintain cold foods at proper serving
temperatures. The unit should the intended
purpose only.
a)
Adjust the position of the shelves
DAILY: Wipe all spills at once.
accommodate required storage needs.
WEEKLY:
b) Switch the power to the "ON" position
a)
b)
Remove the wire shelves and side rack
shelf supports. Clean these items
separately using a mild, non-abrasive
detergent and soft cloth.
c) Pre-chill the cabinet to the full, factory preset
temperature of 36°F ±3°F (2.C)
d) Load the refrigerator with chilled foods only.
Before loading, use a food thermometer to make
certain all products are at a temperature of 41°F
(5°C) maximum or less. Cover foods to reduce
moisture build-up on the inside wall of the
cabinet. To maintain the proper refrigerated food
temperature, open the door only when
necessary. The mobile refrigerated door may be
locked if required.
With a mild, non-abrasive detergent and
water, use a soft cloth to wipe the
interior liner of the storage compartment.
Begin at the top and work down. Wipe
the gasket surrounding the storage
compartment opening.
c)
d)
Using a mild detergent and water, wipe
the vinyl door gasket. Make certain to
wipe under the gasket to remove any
mildew or residue.
5.0 CLEANING and MAINTENANCE
A
thorough, periodic maintenance
schedule is required to ensure the longest and
most trouble free operation. Maintenance
schedules should be aimed at maximizing the
efficient use of maintenance personnel, reducing
down-time, and providing the orderly acquisition
of spare parts support.
Wipe interior surfaces with a clean cloth
and sanitizing solution for use on metal
and vinyl food contact surfaces. This is
an important step to control the build-up
of unwanted mildew and mold on the
evaporator coil and fan.
e)
f)
Vacuum right, left and back panel grill
vents to maintain maximum air flow.
Wipe the interior of the unit with a mild
detergent and water. Always wipe with
the grain of the stainless steel to prevent
scratching the finish.

SCHEDULED MAINTENANCE
6.0 MAINTENANCE
6.3 THERMOSTAT ADJUSTMENT
Remember to de-energize the unit by switching
the toggle switch located on the control panel to
the "OFF" position. Disconnect the unit from the
power source.
Before making any adjustment to the thermostat,
check the door gasket for proper seal. Proper
adjustment can be tested by pulling a dollar bill
through the gasket seal and feeling a slight
resistance. If it is determined a proper seal is
maintained around the full perimeter of the
6.1 MONTHLY INSPECTION & SERVICE
gasket,
a
thermostat adjustment may be
necessary.
CHECK THE INLET AND OUTLET ENDS OF
THE DRAIN LINE to make certain there are
no obstructions. If an obstruction is found:
1. Access the 'machine status' menu by

2. To display the set point value, press the
"SET" key again. The value appears on the
display.
Use compressed air to unblock an obstructed
drain line in a forced air evaporator model.
Remove the drain line at the evaporator coil and
attach an air-line using 60 pounds of pressure.
The use of chemicals to clear a clogged drain is
not recommended.
3. To change the set point value, use the "UP"
and "DOWN" key within 15 seconds.
