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
clockwise
to remove the cover from the dryer.
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
counter-clockwise
and tight until snug. Do not over tighten.
6. Reconnect the power source.
Diagnostic LED’ Display
The printed circuit board includes a set of LED’s that indicate the operational status of the hand dryer. When
contacting World Dryer Technical Service, be prepared to remove the dryer’s cover and provide the condition of
the LED’s as they can be helpful in troubleshooting the dryer. See Figure 1 for location of diagnostic LED’s on the
printed circuit board. See Table 4 for an explanation of LED function.
