ELECTRICAL POWER

Turn on the electrical power supply to the dryer; set all circuit breakers to on, including the safety discon- nect handle mounted on front of the dryer power panel.

CONTROL POWER

SWITCH

Turn the control power switch to on. The switch will light up. A copyright message, model number, total run- ning time in hours and minutes, cur- rent date and time will appear. At this point the controller will lock out all other dryer functions. Once the date and time appear, press reset and the dryer will perform its safety circuit check. If a fault is found, the cause will be displayed on the LCD. If all are found safe, the controller will sup- ply power to the electronic fuel shut- off valve, if so equipped, and the dry- ing mode switch will light up, indicat- ing that the dryer is ready to be started.

POWER START BUTTON

Push the dryer start button, and all the selector switches on the control panel will be activated.

FUEL CHECK

If using LP gas, make sure the tank has plenty of fuel and that the tank does not have a regulator mounted to it. If using natural gas, make sure an adequate supply is available.

If using LP gas, slowly open the main fuel supply valve at the tank. If using natural gas, turn on the valve along the supply line. Then, open the electronic shut off valve (Maxon valve), if so equipped, or open the manual shut off valve on the dryer to allow fuel flow to the dryer. In- spect all gas lines and connections for possible leaks.

Any gas leaks must be fixed immediately!
