HANDLING & INSTALLATION
Inspecting for Damage
NOTE: The transportation company or other parties involved in the shipment are responsible for loss and/or damage.
When direct delivery was made by the transportation company, follow the procedure as outlined in the following
steps: Always inspect before and after uncrating. Inspect the uncrated unit(s) before locating (preferably at the
point of unloading by the transportation company.) You may leave the skid on the unit for ease of locating it later.
a) Damaged cartons or containers - If these are damaged in any way, open them and inspect the contents
in the driver’s presence.
b) Have the driver note the nature and extent of the damage on the freight bill.
c) Notify the transportation company’s office to request an inspection. Carrier claim policies usually require
inspections to be made within 15 days of delivery.
d) Always use care when removing shipping tape, blocks, pads, hardware, or other materials. Retain all
crate and packaging material until you are satisfied that the unit is completely operational.
e) Contact factory if technical assistance is required.
f) If damage is noticed (whether before or after uncrating the unit) the following claim procedure must be
completed.
Inspecting for Shortages
NOTE: Refer to the “Inspecting for Damage” instructions and follow the procedure described.
a) Check the number of cartons and/or containers delivered with the quantity shown on your receipt.
b) If the quantities are not the same, have the driver note the shortage and file your claim accordingly.
Filing Claims
a) File a claim for loss or damage at once with the transportation company for:
1. A cash adjustment
2. Repairs
3. Replacement
b) When filing your claim, retain all packaging materials and receipts.
Handling the Cabinet
The refrigeration system of the cabinet is designed to operate with the cabinet located on a flat surface. Avoid
tilting the cabinet more than 30° to any side. If the cabinet must be tilted on an angle for handling or moving
purposes, allow it to sit in an upright position 20 to 30 minutes prior to plugging it in and starting the cooling of the
storage compartment. DO NOT DRILL HOLES IN THE CABINET WALLS. THIS WILL VOID THE WARRANTY.

Removing the Skid
Remove the front and rear covers. Remove the four (4) bolts securing the cabinet to the skid. Carefully slide the
cabinet off the skid onto the floor.
Locating the Cabinet
This model is a display cabinet and should be positioned to expose the illuminated displays to customers in the
store and provide a clear space behind for the person serving.
Select a location where you are sure that the cabinet won’t be exposed to heat sources such as sun through a
window, store heating or cooling ducts, exhausts from other cabinets, etc. Make sure there is adequate space on
the serving side for loading cabinet and serving efficiently. The following must also be observed in order to
properly locate the cabinet:
a) The cabinet must be installed on a sturdy and solid, level floor.
b) The cabinet should be installed in a protected, dry, and well-ventilated area, away from any heat source.
c) The cabinet is designed to be installed in an environment where the temperature is at or below 75F and
the relative humidity is 55% or less.
d) The front, back and top of the cabinet must be open for compliance with safety and sanitation standards.
The sides require no clearance. Blocking the airflow to the condensing unit will adversely affect the
performance and will potentially void the warranty.
Leveling the Cabinet
Level the cabinet using a spirit level on top. Level front to back and side to side to assure quiet operation and
satisfactory door and drain operation. Shim under the cabinet base as necessary to assure a level cabinet. To meet
NSF requirements, these cabinets must be sealed to the floor with an NSF listed or FDA approved sealant.
Setting up the Cabinet
Cabinets are shipped with the pilasters in place. Shelving is also supplied with the cabinet.
Shipping material (cardboard, paper, plastic, ties, etc.) should be removed from shelving and the product area.

Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock
hazards. This appliance should be plugged directly into a properly grounded three prong receptacle.
Where a two-prong wall receptacle is encountered, it must be replaced with a properly grounded
three-prong receptacle in accordance with the National Electrical Code and local codes and
ordinances. The work must be done by a licensed electrician (cabinet should be on a dedicated
circuit unto itself. Refer to serial data for correct circuit ampacity).
(USA) 120 VOLTS
Power Supply Switch
NOTE: When servicing or cleaning supply power must be turned off. The power supply switch is located at the rear of
each cabinet behind the lower rear grill. The switch is incorporated into the electrical box assembly.
The light switch is located at the rear of each cabinet behind the lower rear grill. The switch is incorporated into the
electrical box assembly.
These cabinets utilize a microprocessor control to manage both cavity temperature and defrost functions.

Cabinet Operation-Refrigeration Mode
Upon setting the cabinet in its final location, turn power supply on. The cabinet display should be indicating the
cabinet temperature. There is a three minute time delay sequence built in each time the supply power is lost
(compressor circuit). Evaporator fan starts and lights come on (medium temp models). Three minutes later the
compressor starts. On low temp models the evaporator fan delays until the evaporator coil reaches 28°F.
The EVCO DIGITAL CONTROL located behind the lower front grill panel has several functions:
Display cabinet temperature
Change cavity set point temperature
NOTE: ON MED TEMP CABINETS DO NOT SET BELOW 33°F.

DOOR REMOVAL(Rear)
Aligning Doors
Proper alignment of the cabinet doors will eliminate
hinge binding and provide correct gasket seal.
1. Check cabinet level and door alignment by firmly
closing each door. Observe the movement of the
other doors. They should open slightly, then
close and seal.
2. The hinge has slotted mounting holes for
adjustment.
3. Additional adjustment can be made by adding
shims between the hinge wing and either the
door or the cabinet face.
Door Gasket Removal:
Allow door to warm up to room temperature. At one corner simply pull the gasket out of the plastic groove
provided. Replace new gasket by firmly pressing the rear dart of gasket into the plastic groove all the way around
the door.
