Caution
Improper mounting could result in personal injury or property damage. Follow the mounting height recommendations in Table 2. On a stud wall, one side of the hand dryer should be mounted to an existing stud.

Unpacking

Unpack all items from the shipping box. Packaged items should include hand dryer, owners manual, mounting template and tamper-proof wrench. Review and report any missing or damaged items.

Installation

1. Disconnect the power source at the distribution panel.

2. Determine the recommended mounting height for gender/age (Table 2). Select a mounting location where no reflective surfaces )countertop or wash basin( are closer than 18 in )46 cm) below the dryer. Avoid mounting where the dryer may be directly exposed to natural light  (sunlight). When mounting adjacent to an existing dryer, the dryers should be spaced at least 24in (61 cm) apart.

3. Select the access for electrical connections through the rear or bottom of the dryer’s mounting plate matching the supply wiring access.

4. Using the mounting template provided, mark locations for the mounting bolt holes on the wall.
   For stud walls, ensure at least one fastening location will be secured to a stud.

5. Use the tamper-proof wrench supplied to loosen the cover mounting screws (turn screws clockwise) to remove the cover from the dryer.

6. Fasten the base to the wall, using the type of bolts recommended (Table 3).

7. Connect the dryer to the supply wiring.

8. Replace cover, tighten cover mounting screws (turn screws counter-clockwise) making certain not to over-tighten.

9. Connect the power source at the distribution panel.

Adjusting Blower Speed

These models include adjustable blower speed control for (3) levels of operation – Hi, Med and Low. The switch is located on the printed circuit board inside the dryer as shown in Fig. 1 below.

Note: The factory setting for the blower speed control is “Hi”.
To adjust blower speed:

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. Locate the switch on the printed circuit board inside the dryer as shown in Fig. 1 below, and adjust blower speed as desired. (Note: When Med or Low speed is selected, LED 3 on the printed circuit board will be lit).
   
   Reassemble the dryer cover using the security hex key supplied to turn the cover mounting screws counter-clockwise and tighten until snug. Do not over tighten.

4. Reconnect the power source.

Accent Lighting

The dryer’s accent lighting can be adjusted to operate continuously or only when the dryer is activated for drying hands )default factory setting(. Most energy efficient operation is with the default factory setting. To change the lighting mode, press the light mode switch shown in Fig. 2 below.

Maintenance and Cleaning Instruction

IMPORTANT: The dryer may collect lint and debris that is naturally present in the air. Excessive build up of lint and debris can damage the motor and heating element. The dryer should be cleaned on a routine schedule to maintain the dryer in good operating condition With light to moderate wash room traffic, cleaning once a year is recommended. If wash room traffic is high, cleaning every 6 months is recommended.

To clean the hand dryer:

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. Use a soft-medium bristle paint brush to clean lint, dust and debris from the air intake slots, and the motor’s exterior.
4. After cleaning, 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.

HEPA Filter Replacement
High efficiency particulate absorption )HEPA( filters remove a minimum of 99.97% of particles 0.3 microns in size or larger.
The service life of a HEPA filter depends on the environment in which the dryer is installed and frequency of use. High traffic washrooms or high usage will require more frequent inspection and replacement of the HEPA filter. When visual inspection of the HEPA filter shows excessive buildup of lint, dust and debris, the filter should be replaced.
Examining and changing a HEPA filter regularly keeps hand dryers working efficiently. Operating a hand dryer with an excessively dirty or clogged filter can damage your machine.
The HEPA filter cannot be cleaned and re-used.
Do not clean the HEPA filter or allow it to come into contact with water.
To inspect or replace the HEPA 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 HEPA filter is easily done by sliding the filter in its mounting track on the motor cap.
4. After replacing the HEPA filter, 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.
5. Reconnect the power source.

Coarse Particulate Filter

The optional accessory coarse particulate air filter prevents 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.
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 lifting the filter bracket upward out of the filter housing. The coarse filter should be removed from the bracket for cleaning or replacement.
4. 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. 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 this 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.
