1. SHIPPING DAMAGE
1.1 General
All equipment should be thoroughly examined for shipping damage before and during unloading.
This equipment has been carefully inspected at factory and the carrier has assumed
responsibility for safe arrival. If damaged, either apparent or concealed, claim must be made to
the carrier.
1.2 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 forms.
1.3 Concealed Loss or Damage
When loss or damage is not apparent until after equipment is uncrated, a claim for concealed
damage is made. Upon discovering damage, make request in writing to carrier for inspection
within 15 days and retain all packing. The carrier will supply inspection report and required claim
forms.
1.4 Location

3/15
These merchandisers are designed for indoor operation with a recommended operating room
ambient temperature of 75° F (24° C)/55% rh. Their performance is affected by store air currents
when the doors are open. Do NOT allow air conditioning, electric fans, or open doors and
windows to create air currents around these merchandisers nor should they be exposed to direct
sunlight or other heat sources.
NOTE: The condensing unit draws ambient air through the front of the unit and discharges hot air
out the rear of the unit. In order to maintain proper refrigerator performance and compressor life,
a mini mum space of 4 ” ( 10 cm) must be maintained between the refrigerator and
surrounding surfaces.
2. PREPARATION OF CABINET FOR OPERATION
Removing Cabinet From the wooden Pallet
Move the merchandiser as close as possible to its permanent location. Check refrigeration
lines to see that they are “free” and no damage has occurred during shipping. Check fan
blades for free operation.
2.1 Leveling Cabinet
These merchandisers must be installed level
(front to back and end to end) to permit maximum draining of the condensate water as well as
proper door alignment and operation.
The merchandiser has been shipped with 6 adjustable foot bolts installed. Level the unit by
placing a level on the merchandiser and make it to level by adjusting the foot bolts.
2.2 Shelf Installation
After the cabinet has been leveled and is in its final position, the shelves may be installed.
Shelf spacing is adjustable by positioning the shelf supports according to your loading
requirements.
WARNING
(Freezer. Models) Do NOT place product directly on floor of merchandiser. Locate
bottom shelf in the lowest position to the floor of the merchandiser (approximately 3” [7.5
cm] off bottom) before loading. Failure to comply may result in product loss.

2.3 Door seal (closing mechanisms).
Hinged Doors. Check to ensure the door torque is capable of closing the door
automatically. Open the door 30 degrees and release it, the door should close and seal.
2.4 Fan Cycle Switch (Hinged doors, freezer only )
The evaporator fan is cycled off upon a door opening by a switch located above each door.
This reduces the amount of warm moist air introduced to the evaporator coil during door
openings
With the door open, depress the switch to ensure the evaporator fan is working.
2.5 Lamps.
Turn the lighting switch on to ensure the lamps are operating correctly. Check to ensure the
lamps are in their place.

4. REFRIGERATION SYSTEM

7/15
Defrost Cycle (Low Temperature Models)
The evaporator fin coil is defrosted by an electric defrost heater located on the underside of the coil.
The defrost cycle is initiated and terminated by the controller fitted on the electrical box. This control
not only terminates the defrost cycle, but delays the fan start-up after the defrost cycle to prevent the
residual heat of heater from being blown into the product area.
5. START UP / OPERATION
5.1 Electrical Supply
WARNING: Equipment MUST be GROUNDED!
Wiring of the unit is complete when it is shipped from the factory. The unit is supplied with a three
conductor electrical cord which extends from the rear of cabinet. Plug the cabinet into correct
grounded outlet. It is recommended that a separate circuit be run for each cabinet to prevent the
possibility of another appliance blowing a fuse, causing subsequent loss of product.
Control setting, please see the appendices at the last page. The pre-set parameters in factory as
below:

5.3 Lighting
Interior light and light box are controlled by a manually operated switch. The switch is located near the
controller.
5.4 Defrost Water Evaporation
External drain plumbing is not required. Behind the case, there is a plastic soft pipe directing
defrost water from the evaporator coil to water tray on condensing unit. The water tray in the
condensing unit area serves as a reservoir for the storage of the water until it is evaporated by a hot
gas loop from the compressor.
6. MAINTENANCE
Maintenance
Long life and satisfactory performance of any equipment is dependent upon the care given to it.
To ensure efficient operation, proper sanitation and minimum maintenance, the cabinet should be
thoroughly cleaned, debris removed and the interior cleaned regularly.
CAUTION
TO AVOID PERSONAL INJURY OR DAMAGE TO ELECTRICAL COMPONENTS ALWTAYS
DISCONNECT UNIT FROM MAIN POWTER SOURCE BEFORE SERVICING OR CLEANING
6.1 Cabinet Surfaces (Interior and Exterior)
To preserve finish, the cabinet should be cleaned with a mild solution of soap and warm water
only, using a soft cloth or sponge. DO NOT use any type of caustic soap, abrasive cleaner, or
steel wool scouring pads which can mar the cabinet finish.
6.2 Condenser
The air cooled condenser should be cleaned regularly. A dirty condenser restricts air flow,
causing decreased refrigeration efficiency. (Clean every month or as required).
I ) With main power supply disconnected, remove the front grill from front of lower cabinet. Most
dirt will collect on the air intake side of the condenser. This is opposite the fan motor.
2) Use a bristle brush to loosen the dust and dirt and remove with a vacuum cleaner. When
cleaning condenser line beware of fin edges as they are sharp
3) If the merchandiser is located in an area susceptible to grease collecting on the condenser,

9/15
scrub with a solution of warm water and detergent. Care should be taken to keep solution away
from wiring and electrical components.
Check for loose items before replacing panel.
6.3 Evaporator Housing
The thermostat “OFF” position disconnects the condensing unit only. The evaporator fan
motor will be energized until the unit is disconnected from the main power source. Remove the
fasteners to lower the evaporator housing for cleaning and/or service.
NOTE: Evaporator fan will cycle “ OFF ” during defrost cycle. Evaporator fan will delay
approximately 5 minutes after each defrost cycle and initial start-up on freezer model.
