INSTALLATION

Carefully remove carton or crate from unit. Remove all loose packing materials,  making sure that no
small parts or accessories are lost.  Inspect unit for concealed damage before discarding packing
materials.

It is the responsibility of the installer to comply with all local codes.

Install the protector guard.  Installation instructions for the different model  protector guards are found
on pages 4, 5 and 6 of this manual.  Refer to these for installation details.  If protector guard is
equipped with lights, be sure that the protector guard light switch located at the end of the protector
guard is turned off.  For mechanically refrigerated units make sure that the switch in the control panel
is turned off. Connect the electrical power cord and NEMA 5-15P plug to a 120 volt 15 AMP power
source.

Remove the access panels to the condensing unit and check that the fan turns freely and the condenser
is not blocked.  The service valves have been opened at the factory and the pressure control is pre-set
to the proper temperature and should need no further adjustment.

START-UP AND OPERATION

When installing unit, make sure there is a minimum 2” of air space to allow free air flow into the
louver panel located on the end of the unit.  Also allow 12” of free air space for the louvered panels
located in the front and in the rear of the cabinet.

Turn the switch in the control panel to the “ON” position.  The pilot light will light and the condensing
unit will start.  Allow the unit to run for about 15 minutes.  The bottom of the cold pan should start to
frost over and should be cold to the touch.

THEORY OF OPERATION

The Cold Ice Pan Food Table (

CI

) is designed to be used with ice to display cold foods and salads

during the meal period.  There is no mechanical refrigeration used.  Ice is packed around food pans
placed into the food well to provide cooling.  A one-inch drain valve is provided for draining excess
water from melted ice and for ease of cleaning.

The Mechanically Refrigerated Cold Food Table (

CM 

) is designed to be used with or without ice to

display cold foods and salads during the meal period.  The mechanical refrigeration system uses a 1/3
horsepower compressor and thermostat control to provide cooling to copper coils mounted to the
bottom of the food well. Crushed ice should be used along with the mechanical refrigeration system to
achieve the optimum control of food temperatures over longer periods of time.

NOTE

:  Cold Food Tables are NOT refrigerators and will NOT keep food cold for long  periods of

time.  Food should always be placed into the table directly from the refrigerator at as low of a tempera-
ture as possible.  When the food in the table reaches a temperature of 38° to 40° Fahrenheit it should
be placed back into the refrigerator and replaced with cold food from the refrigerator.
