Coarse Particulate Filter
(for models not including HEPA filters)
The dryer has a coarse particulate air filter to prevent lint and debris build up that can damage the
motor and heating element. Routine replacement or cleaning of the air filter is needed to maintain
the dryer in good operating condition. With light to moderate wash room traffic, replacing or
cleaning the air filter once a year is recommended. If the wash room traffic is high, the air filter
should be replaced or cleaned every 6 months. Read complete instruction before proceeding.
To replace or clean the coarse particulate air filter:
1. Disconnect the power source.
2. Use the security hex key supplied to turn the cover mounting screws
3. Removing and replacing the air filter is easily done by gently pulling the filter away from the filter housing.
4. To clean the coarse particulate air filter, remove from filter from the filter housing. Use soft-medium bristle ½" paint
brush to clean lint, dust and debris from the filter. If air filter cannot be completely cleared of debris, replace the filter.
5. After replacing the air filter into the filter housing, reassemble the dryer cover using the security hex key supplied to
turn the cover mounting screws
6. Reconnect the power source.
