Dryer Pre-Season Checks
Before staring the drying for the first time in a drying season, perform the following checks. If any of the
checks fail to produce the stated result, the customer should consult the dealer.
Do not attempt to use the dryer unless all the pre-start checks have been successfully completed.
Inspect the Metering Rolls
Open all metering roll access doors and inspect each compartment for any bolts, nuts or other foreign
material that may cause possible jamming of the metering rolls.
Check Control Panel Switches
Before applying electrical power to the dryer, be sure that all switches on the dryer control panel are in the
OFF position.
Electrical Power
Turn ON the electrical power supply to the dryer, set all circuit breakers to ON, including the safety
disconnect handle mounted on front of the dryer power panel.
Control Power Switch
Turn the Control Power switch to ON. At this point, the controller will lock out all other dryer functions. Once
the Boot Screen appears, touch the Start button and the dryer will perform a safety circuit check. If a fault
is found, the cause will be displayed on the main screen. If all are safe, the controller will supply power to
the electronic fuel shut off valve (maxon), if so equipped and the Start switch will illuminate, indicating that
the dryer is ready to be started.
Start Switch
Push the Start switch 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
on the liquid line. Slowly open the main fuel supply valve at the tank. Then, open the manual shut off valve
on the dryer to allow fuel flow to the dryer.
If using natural gas, make sure an adequate supply is available. Turn ON the valve along the supply
line. Then, open the manual shut off valve. Inspect all gas lines and connections for possible leaks.
WARNING
Before attempting to operate the dryer, make sure all safety shields are in place, all
bottoms are cleaned out and rear access doors are closed and all personnel are
clear of the dryer.
WARNING
Any gas leaks must be fixed immediately.
