OPERATION CONT’D 

OPERATING Do’s and Don’ts 

 

DO: 

Insure all dishes placed in the cheese-melter are oven safe. 

Pre-heat pans in the cheese-melter or on a stove. 

Turn products halfway through cooking, as needed. 

Use the unit in Automatic as much as possible, use Constant during peak periods. 

DON'T: 

Do not use the cheese-melter as a cooking or baking device, it is best suited for 
finishing dishes immediately prior to serving. 

Do not use the unit to heat or thaw chilled or frozen product. 

Do not place aluminum foil on the rack or bottom shelf. This will reflect heat and 
expose components to unnecessary high temperatures. 

Do not move rack from one position to another without hand protection. 

TYPICAL OPERATION 

AUTOMATIC MODE 

When the mode select switch is placed in "AUTOMATIC" and the power switch 
is moved to the "ON" position, power is applied to all of the elements. 

The power switch energizes a contactor that connects the elements to the 
incoming power leads.  Because the elements are connected in series, all 
elements have power applied.  With all elements connected in the circuit, the rear 
element appears dimly lighted and the front elements appear not energized. 

In the "AUTOMATIC" mode, the elements are activated to provide full heat only 
when product is placed on the rack.  Placing product on the rack causes the shelf 
to tilt down, activating a micro switch via the sliding actuator connected to the 
right front corner of the rack. 

Closing the micro switch energizes a 2-pole heating contactor causing both sets 
of contactor points to close.  One set of contactor points is connected in parallel 
with the rear element.  This connection, when activated, changes the circuit 
resistance/electrical configuration. 

Electrically this presents an alternate current path by shorting across the rear 
element.  The effect is that the front and middle elements energize, while 
appearing to de-energize the rear element.  Front and middle elements now have 
voltage applied for their rated operating level.  For 208-volt and 240-volt units, 
the voltage to these elements is 104 and 120-volts, respectively. 

CONTINUOUS MODE 

In this mode of operation, the heat contactor is energized at all times.  Movement 
of the rack does not energize or de-energize the elements.  The rear element does 
not light or heat at any time.  The front and middle elements are energized at all 
times.
