GENRAL MAINTENANCE
KEEP ALL GUARDS AND SCREENS IN PLACE
DISCONNECT ALL POWER SOURCES
BEFORE DOING ANY REPAIR, MAINTENANCE OR INSPECTIONS!
BEGINNING OF EACH DRYING SEASON:
1.
Remove inlet screen. With power off, check for foreign material on fan blade. Turn fan by hand to be sure it rotates
freely.
2.
Check wiring of fan and heater. Look for loose connections, bare wires, or rodent damage. Be sure to check ignition wire
and flame sensor wires for any damage.
3.
Examine the flame/spark rod for cracked insulation. Flame/spark rod should be examined periodically throughout drying
season.
4.
All plenum controls should be checked.
5.
Check all plumbing connections for leaks, using soap solution.
6.
Check vaporizer adjustment daily. Weather condition changes can demand new adjustment.
AFTER DRYING SEASON:
The balance of a vane axial blade or fan wheel is very critical. Vibration can cause the fan housing to crack. To prevent this,
check behind the blade for dirt, dust, or foreign material.
Burn fuel out of lines and turn off at source.
Cover fan inlet to keep out weather, pests, and to prevent “wind milling” which can cause wear on the start switch in single
phase motors.
DURING OFF SEASON:
Every six weeks, remove inlet cover and operate fan to redistribute grease in bearings. Let motor warm up enough to force
out any accumulated moisture.
Make sure control box cover is in place and secured. Turn off power and fuel at source.
