EQUIPMENT SET UP & OPERATION :
- Once the unit has been taken out of the shipping carton and has been unpackaged, check to
make sure that the lightbulb is securely in its socket.
- Before loading prepared food product into the warmer, you must preheat the unit for 30 minutes
at a setting of 4 or 5 on the thermostat dial. After the preheat time has elapsed you can then go
ahead and place the previously prepared food product inside and adjust the thermostat
accordingly.
- The amount of product placed in the warmer will affect the performance of the warmer.
We suggest periodically checking the internal temperature of product and adjusting the
temperature settings if necessary. Keep door(s) closed when not serving.
