TEST FIRING
DRYER PRESEASON CHECKS
This section gives a series of checks to be carried out on the dryer before starting for the first time in the drying
season. If any of the checks fail to produce the stated result, you should consult your dealer.
YOU SHOULD NOT ATTEMPT TO USE THE DRYER UNLESS ALL THE PRE-START CHECKS HAVE
BEEN SUCCESSFULLY COMPLETED.
BEFORE ATTEMPTING TO
OPERATE THE DRYER MAKE SURE ALL SAFETY SHIELDS ARE IN PLACE, ALL BOT-
TOM CLEAN OUT AND REAR ACCESS DOORS ARE CLOSED AND ALL PERSONNEL ARE
CLEAR OF THE DRYER
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 (see page 12), touch the START DRYER 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 found safe, the controller will supply power to the electronic
fuel shut-off valve (Maxon), if so equipped, and the start switch will light up, indicating that the dryer is ready to be started.
START SWITCH
Push the dryer 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 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.
If using natural gas, make sure an adequate supply is available. Turn on the valve along the supply line. Then, open the elec-
tronic shut off valve (Maxon valve). Inspect all gas lines and connections for possible leaks.
Any gas leaks must be fixed immediately!
LOAD AUGER
With the grain supply shut off, quickly bump the load auger switch to manual, and see if the load auger rotates clockwise as
viewed from the drive end, or counterclockwise if the dryer is a front load model. If the wet grain supply auxiliary is wired to
the dryer it should also rotate in the correct direction at this time.
Turn the load auger switch to the auto position. The top auger and wet grain supply auxiliary should run for eight (8) min-
