When a laundry dryer is turned on it quickly produces
dynamic air pressure build up in the duct system of
which the dryer booster fan is connected to. When the
pressure build up within the system is greater than the
air pressure switch set point the pressure relay closes
and the timer cycle is initiated which than completes the
electrical circuit and the booster fan starts. The timer
cycle relay period is 600 seconds closed and 60 sec.
open. If the dryer is on it will continue to produce
dynamic pressure in the system and the booster fan will
continue to run for additional timer cycles. Once the
dryer is turned off it no longer produces dynamic air
pressure in the system. When the air pressure within the
duct system is less than the switch set point pressure
the pressure relay will open. The booster fan will
continue to run until the completion of the 600 second
closed timer cycle. During the 60 second open timer
cycle power is interrupted and the booster fan will slowly
come to a stop and remain off until the dryer is turned
back on and the system cycle is once again initiated.
NOTE: Please read and follow the installation
instructions. The positing of the air pressure switch is
critical for booster fan operation. Please consult local
building and electrical codes prior to installation.

CLEANING INSTRUCTIONS:
1. Before cleaning the unit, switch power off at service panel
and lock it. If service panel is unlocked others could turn
the power on unexpectedly and cause fatal electric shock
to the cleaner.
2. Make sure there is no power to the motor.
3. Clean fan blades of lint accumulation with a cloth or small
smooth brush as required (at least twice annually) by
removing two wing nuts from the motor mounting plate
then motor will swing open.
4. Tighten the wing nuts after cleaning.
5. Turn the power “ON” and check if the fan is working
properly.
6. It is recommended that a Lint Trap be installed.
