CLEANING AND MAINTENANCE (Continued)
CLEANING THE EXTERIOR OF THE UNIT
1. Clean the air filter at least once a month by removing it
from the unit and washing or vacuuming any dust from
its surface. Allowing dust to collect on the filter will
cause the PTAC to lose efficiency and eventually
malfunction.
2. When cleaning the filter, be sure to vacuum any dust
from the return air grille surface as well.
3. Clean the exterior of the cabinet as desired with a mild
soap or household cleaner.
TROUBLESHOOTING
NO HEAT OR COOLING:
Check to see if the unit has power
and if the thermostat is satisfied. If the thermostat is
not
satisfied, refer to the wiring diagram and check control
components for continuity.
DANGER
Before servicing the RetroAire Single Motor PTAC,
be sure to turn off electrical power to the unit.
Failure to do so can result in a fire, explosion or
electrical shock causing property damage,
personal injury, or death.
