indicator lamp and the fan will operate continuously whenever the
heater is plugged in.
2. Be sure the cabinet door(s) are fully closed during the pre-heat time.
3. Set cabinet to desired temperature (see Programming Instructions
below).

30 minutes.
5. Food serving temperature will vary with the mass, type and quantity
of food being held.
6. During loading, the cabinet temperature will rise. Close the door and
wait 10-15 minutes for the cabinet to recover air temperature before
disconnecting from the power source.
7. Be sure to remove the plug from the outlet and wind the cord on the
cord bracket or push handle before moving the cart. Move the cart to
the service area as quickly as possible.
8. Upon reaching the service area, reconnect the refrigerator module to

thermometer to see if the temperature is are the desired level). If not
adjust the thermostat as required.
