CLEANING INFORMATION
FILTER
For greatest efficiency, the aluminum filters should be removed and
cleaned periodically. To remove the filters, loosen the screw in the
center of each filter.
To clean, the filter should be soaked in hot water and detergent
then thoroughly rinsed. The aluminum filter can be cleaned in a
dishwasher.
EXTERIOR SURFACE
To preserve its lasting beauty, clean with a mild detergent. DO NOT
use abrasive cleaners.
MOTOR SPEED
TROUBLESHOOTING
If you have a motor speed problem, please check the following list
for possible troubles.
. Blower assembly installed wrong - instended for vertical dis-
charge, but installed for horizontal discharge (FIGURE 4).
2. Damper flap - not opening.
3. Reduced airflow because the duct is too small, too long, or has
too many transitions in the system.
4. Restriction in the duct (foreign matter, debris).
5. Undersized or restructive roff or wall cap.
6. Damper flap in roof or wall cap - not opening.
7. Wait for 20-30 seconds between speed changes for RPM to
adjust.
By removing or correcting these adverse factors, the motor speed
control will be able to decrease from maximum RPM.
