be connected to the dryer’s backplate.
NOTE: DO NOT INSTALL DRYER OVER WASHBASIN
INSTALLATION
1. Make sure the power source is switched off. Installation must be carried out in
accordance with the current edition of the local wiring regulations code having
jurisdiction. Installation should be performed only by a qualified electrician.
2. Place template against wall at desired height (see mounting height
recommendations) and mark locations of 4 mounting holes and wire service entry
at knockout (KO) location. Note: For two or more dryers, dryers should be no
closer than 24 inches (610 mm) on center.
3. Remove and retain 2 cover screws and cover.
4. For in-wall (concealed) power supply - Provide supply wire to KO location
according to local code and attach securely to chassis at KO with appropriate
strain relief connector (not supplied).
5. Attach dryer to wall. For wood wall/studs use ¯1/4 inch (M6) screws at length that
will ensure 1 inch (25 mm) min. stud penetration. For masonry walls use expansion
bolts or anchors for ¯1/4 inch (M6) screws to ensure penetration 1/4 inch (6 mm)
deeper than anchor. Shim if necessary to ensure base plate is flat against wall.
6. C
onnect supply and ground wires to terminal block where indicated or connect

TROUBLESHOOTING
Symptom
Corrective Action
If the dryer will not
run
First ensure that the breaker supplying the dryer is operational. If
it is, disconnect the power and remove the dryer cover. Check for
obstructions blocking the rotation of the blower and clear any found.
If it spins freely, check the motor and thermostat for proper operation
out of the unit. Replace any failed items. Taking suitable precautions to
avoid shock hazard, reconnect the power and check for voltage at the
terminal block. If there is power and the dryer will not run, replace the
timer assembly and/or sensor module.
If the dryer cycles by itself, or
runs all the time, or shuts off
by itself while in mid-cycle
Ensure that there is no obstruction on or in front of the infra-red sensor.
Clean any dirt off the sensor lens. Check for voltage spikes on power
line. If the problem persists, replace the timer assembly and/or the
sensor module.
If the element gets hot but
the fan motor does not turn
Disconnect the power. Remove the dryer cover and check for
obstructions in the fan housing. Damaged fans must be replaced. If
there are no obstructions, replace the motor.
If the unit runs but makes a
buzz noise
Disconnect the power. Remove the dryer cover and check the fan for
obstructions and/or rubbing on the housing as it rotates. Remove any
obstructions and replace fan if the rubbing condition exists.
If the fan motor runs but the
element does not get hot
(Dryer blows cold air)
Disconnect the power and remove the dryer cover. Check for loose or
damaged wires. Remove the blower housing. Check the element for
signs of burning or breakage. Damaged element must be replaced.
If the element does not appear damaged, disconnect it at the timer
assembly and check element wire continuity (see tech spec). An open
circuit indicates damage to the element wire and to the integral
temperature limit control (TLC). Separate the TLC and test for open
circuit. If this is the case, replace the element and/or the thermostat.
If the motor makes ticking/
winding noise when it runs
Disconnect the power. Remove the dryer cover and check the brushes
for worn condition (less than 25/64” (10mm) graphite remains) and
replace them, if necessary. Purchase rebuild kit to perform repair.
