General Safety Information

Failure to disconnect the power source before installation or servicing can

DANGER

• Always disconnect the power source before servicing or installing the hand dryer.

DANGER

• This hand dryer must be properly grounded (Earthed) for safe operation. An identied ground connection point is
supplied on the hand dryer’s wall base.

• We recommend GFCI protection in wet or damp locations or as required by local code.

WARNING

• Use only the electrical power (voltage and frequency) specied for the model hand dryer being installed.

• Connect the hand dryer to the nearest suitable distribution panel.

• To limit a voltage drop, and insure efcient operation, use wire gauge as required by local or National Electrical Code.

• Do not connect to a branch circuit with CB or fuse protection over 15 Amps. This is in compliance with The National
Electrical Code #210-20.

• All automatic model hand dryers must have a dedicated 15 Amp circuit as required by Underwriters Laboratories, Inc. (UL).

• Route all eld wiring away from any moving parts within the hand dryer.

result in serious injury or death from electric shock.

Failure to properly ground this unit could result in severe electrical shock
and/or death.

Risk of re, personal injury or property damage are possible if local codes,
NEC codes or safety recommendations are not followed.

CAUTION Improper mounting could result in personal injury or property damage.

• Follow the mounting height recommendations in Table 1.

Unpacking

1. Remove all packing material. Recycling is recommended.

Installation

1. Disconnect the power source.

2. Remove the two cover-mounting screws. Remove the cover from the dryer.

3. Place the hand dryer base on the wall at desired location. Using Table 1 to determine the recommended mounting
height. When two or more dryers are installed, they should be placed no closer than 24” (60 cm) from center to
center. Mark the location of the four mounting bolt holes and the wire entry hole.

4. For recessed wiring, carry the supply wire to the dryer base plate knockout and attach with an acceptable cable
clamp. The dryer requires two conductors for power plus a separate ground wire.

5. For surface wiring, remove the knockout located at the bottom left corner of the cover. Pass the supply wire
according to local code, through the knockout and attach it securely to the bracket. The dryer requires two
conductors for power plus a separate ground wire.

6. Attach the mechanism rmly to the wall. For wood walls or wood studs, use No. 16 screws of proper length to ensure
1” (25 mm) minimum stud penetration. For masonry walls use expansion bolts or anchors for 1/4” (6 mm) screws of
proper length to ensure penetration 1/4” (6 mm) deeper than anchor. Shim if necessary to ensure that the base plate
is level and at against the wall.

7. Connect the supply wires to the terminal block where indicated. Connect the ground wire to the base plate with the
ground screw.

8. Replace the cover. Do not overtighten the screws.

INSTALLATION MUST BE PERFORMED BY QUALIFIED ELECTRICAL PERSONNEL.

Troubleshooting Chart

Symptom Possible Cause(s) Corrective Action

Dryer will not run Defective circuit board 1. First ensure that the breaker supplying the dryer is operational

2. If it is, disconnect the power and remove the dryer cover. Taking
suitable precautions to avoid shock hazard, reconnect the power
and check for voltage at the wire leads

3. If there is power and the dryer will not run, replace the circuit board

Dryer cycles by itself,
runs all the time, or is
not sensitive enough

Elements get hot but
the fan motor does
not turn

Fan motor runs but
the element does not
get hot

Defective circuit board 1. Ensure that there is no obstruction on or in front of the infra-red lens

2. Disconnect the power. Remove the dryer cover and the screws
holding the circuit board. Ensure that there are no obstructions
between the infra-red “eyes” on the circuit board and the lens

3. If the problem persists, replace the circuit board

Defective fan Defective
motor

Loose or damaged
wires or defective
element

1. Disconnect the power. Remove the dryer cover and check for
obstructions in the fan housings

2. Damaged fans must be replaced

3. If there are no obstructions, replace the motor

1. Disconnect the power and remove the dryer cover. Check for loose
or damaged wires. Remove the access cover on the blower housing.
Check the element for signs of burning or breakage. Damaged
element must be replaced

2. If the element does not appear damaged, disconnect it at the circuit
board and check for continuity across the two element wires. An
open circuit indicates damage to the integral temperature limit
control. If this is the case, replace the element
