   NOTE: The battery will provide power for approximately 16 hours (without solar) before needing a charge; depending on the age and condition of the battery .

OPERATING INSTRUCTIONS

HOW TO HOLD FOOD:
WARNING  Air is VERY HOT when door is opened.
FIRST TIME START-UP:

1. Push the POWER switch to “ELECTRIC”, and run the unit for one hour at 200°F.
   NOTE: DO NOT PUT FOOD INTO CABINET!
   This step is to burn off manufacturing oils and excess adhesive.

2. Let the cabinet cool and wipe inside clean with detergent and hot water before first use.

HOW TO HOLD:

1. Push POWER switch on to “GAS” or “ELECTRIC” .
2. Push the “SET” button on the TEMPERATURE CONTROL . The TEMPERATURE DISPLAY will show “SP1” (set point 1).
3. Press “SET” again and the current set point temperature will be displayed.
4. Press the   ADJUST buttons to adjust to the desired temperature.
5. Press “SET” to save the temperature setting.
6. Preheat cabinet for 45 minutes.
7. Put product into cabinet.

NOTE: Proper food holding temperature is 140°F/60°C or higher.
USING ACCESSORY SOLAR PANEL (Optional):
The solar panel is used to increase the time between battery charges when using the cabinet unplugged in gas mode. To use the solar system, ensure the solar panel cord is plugged into the solar jack, located in the top right corner of the back panel of the unit. Rotate the cabinet and/or tilt the solar panel in order to catch the sunlight. The best possible condition for solar charging is when the sunrays hit the panel straight on at 90° angle.
NOTE: It is recommended to keep the solar panel plugged in even when not in use. It will safely maintain the battery at full charge for an unlimited amount of time if not placed in a dark area. The solar system is not powerful enough to charge the battery from fully drained status in any reasonable amount of time. If the battery is fully dead, plug the cabinet in to a grounded 120V outlet to charge.

2b . Fuse is blown .
NOTE: The power cord can be left plugged in for a long period of time after the battery is fully charged. The internal battery charger will safely “maintain” the battery.
3 . Unit heats up slowly .| 3a . Check operating instructions for preheat times .
3b. Defective electrical or gas components.
4 . Unit does not heat (electric mode) .| 4a . Unit is not on .
4b . Thermostat is set too low .
4c. Defective electrical components.
5 . Unit does not heat (gas mode) .| 5a . Unit is not on .
5b . Thermostat is set too low .
5c . Propane/gas tank has expired .
5d. A gust of wind may have blown out the flame or
prevented ignition of the gas.

NOTE: The control is equipped with an auto-ignite system. On startup and periodically throughout operation, it will attempt to ignite the gas for 10 seconds. If it fails, the “reset” indicator will illuminate and an audible alarm will sound, indicating no heat. If the tank is empty, this will usually happen within 20 seconds, in windy conditions, it could take up to 5 minutes for the alarm to become present. If this happens, turn the power switch to “OFF” and then back to “GAS”, and it will try to re-ignite.
