MAINTENANCE OF MOTORS
WARNING: Make sure all power to the appliance is turned OFF
before proceeding.
Always disconnect the appliance from the main power supply and allow it to
cool before any servicing operation. The motor used on the fan is pre-lubricated
for extended bearing life and requires no further lubrication. However, periodic
cleaning/vacuuming of the appliance around the air intake and exhaust, as well
as the fan is recommended. For heavy or continuous use, periodic cleaning
must be done more frequently. If the heater blows alternating cold and warm air,
check the fan for free movement and for debris restricting air flow. If the fan does
not move freely, the unit must be turned off and the fan replaced immediately in
order to prevent further damage to the unit.
