Coarse Particulate Filter
(for models not including HEPA lters)
The dryer has a coarse particulate air lter to prevent lint and debris build up that can damage the
motor and heating element. Routine replacement or cleaning of the air lter is needed to maintain
the dryer in good operating condition. With light to moderate wash room trafc, replacing or
cleaning the air lter once a year is recommended. If the wash room trafc is high, the air lter
should be replaced or cleaned every 6 months. Read complete instruction before proceeding.
To replace or clean the coarse particulate air lter:
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 lter is easily done by gently pulling the lter away from the lter housing.
4. To clean the coarse particulate air lter, remove from lter from the lter housing. Use soft-medium bristle ½” paint
brush to clean lint, dust and debris from the lter. If air lter cannot be completely cleared of debris, replace the lter.
5. After replacing the air lter into the lter 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.
