1 SAFETY
cDanger of electric shock.
cWARNING Modern appliances are very powerful and use high
technology devices to safely control that power. Failure to use
the correct procedures and the approved parts can create
serious hazards for the person servicing the appliance and for
the user of an appliance with a bad repair. If you do not know
how to service the appliance, do not attempt to do so!
To avoid the risk of serious injury or death while servicing these
appliances:
cBe certain that all power is removed from the appliance before
beginning service.
cCarefully follow all servicing instructions. Verify the instructions
if there are any that you don't fully understand.
cRead and heed all Cautions and Warnings on the appliance
and those with the replacement parts.
cUse caution and proper protective gear when handling chassis
panels. Some of the edges that are not normally exposed may
be very sharp.
To avoid risk of serious injury or death to the users of the appliances:
cCarefully follow all service instructions.
cUse only parts authorized for the application.
cKnow the testing requirements needed to verify the safety of
the service action.
cUse proper, calibrated test equipment.
cDo all indicated safety tests and record results.

2 INSTALLATION
2.1 Basic installation
Dryers shall be installed according to national and local codes.
2.2 Exhaust vents
2.2.1 Locating exhaust vent
Vent can be installed to the rear or right side of dryers. Rear factory
vent can be changed to the right side by moving the connector to the
side and the cap to the rear. Rotate both to the left to remove and to
the right to install, aligning the cap/connector notch with the vent tab.
2.2.2 Installing vent ducts
For best drying, use shortest possible duct length and fewest # of
elbows.
Use the table below when selecting ducting.
# 90º Turns / Maximum Length
Elbows Rigid Duct Flexible Duct
0 20 m 14 m
1 17 m 11 m
2 14.5 m 9 m
3 12 m 7 m
4 9 m 5 m
2.3 Feet (leveling legs)
Using a level front to back and side to side, adjust feet (leveling legs)
until dryer is level. When moving dryers, screw in feet completely
before moving dryers to avoid damage.
To adjust feet
(leveling legs),
rotate left to right
to lower dryer.

4 COMPONENTS
4.1 Dryer Components
Basic components are control module, electric heater, drive motor with
fan, two NTC temperature sensors, two hi-limit temperature
protectors, moisture sensor and broken belt switch.
4.1.1 Electric heater
Dryers have 2700W heaters, which include an NTC temperature
sensor and a manually resettable hi-limit temperature protector.

4.1.3 Lint screen sensors
The front (bearing) shield contains two sensors – accessible after the
lint screen is removed. Along with the heater NTC and hi-limit
protector, the lint screen NTC and hi-limit protector provide
temperature regulation and safety.
4.1.4 Broken belt switch
The broken belt switch prevents the dryer from running if the belt has
broken or been left disconnected. It must be manually reset (by
pushing the left plunger in (viewing rear of dryer) – the dryer will not
run if the switch hasn’t been reset.
4.1.5 Air exhaust duct
Air exhaust duct connects to the fan and allows exhausting through
the rear or right side of dryers.

4.1.6 Fascia (control) panel
Fascia panel contains knob and all buttons – knob and buttons are
factory built into the panel and cannot be obtained separately.
Push left plunger (toward
right) to reset broken belt
switch whenever drum or
belt has been removed for
any repair.

4.1.7 Moisture sensor
Moisture sensor consists of two electrodes (located just left of the lint
screen on the front bearing shield). Moisture from clothes completes
the circuit between the two sensors, showing clothes aren’t dry.
Placing the moisture sensor on the front shield eliminates sensors
inside drums and conductance brushes outside drums.
4.1.8 Door pin
Door pin engages the door switch, notifying the dryer the door is
closed for drying. If the door pin is damaged, the entire door
assembly must be replaced.
A T-20 screw on the door pin cover can be tightened to align the door
pin. Don’t over tighten the screw.
4.1.9 Door switch
Door switch engages the door pin, turning the light on and off and
notifying the dryer the door is closed for drying. To remove it, push
the two latches inward and slide the switch toward the rear of the
dryer.

4.1.10 Door glass cover
The plastic door glass cover can be replaced by carefully prying it out
and snapping it into place.
4.1.11 Front felt drum seal
Dryers have a self-adhesive, Teflon coated, felt front seal which can
be replaced. When replacing the seal, make sure all old adhesive is
removed and no new adhesive gets onto the drum. Any excess
adhesive or residue may cause squeaking.
4.1.12 Drum with bands
Drums have two steel bands around them to make them quieter.

Dryers shut down after 11 minutes if no moisture is detected. Dryers
can be immediately restarted.

5 REPAIR
mCAUTION – 75% of all controls
returned for analysis check out OK. Most
control issues are due to loose connections.
5.1 Disassembly / Reassembly
5.1.1 Fascia (control) panel
Carefully pry off four screw cover, remove four T-20 Torx screws and
lift up panel.
5.1.2 Control module
Remove control module from fascia panel progressively from left to
right, carefully releasing inside and outside plastic latches (1-8 below)
so latches don’t break. Gently pry up left side of control so latches
don’t re-close. Module will release from fascia panel and knob.
Don’t cut cable mounts – cut cable ties holding cables to mounts.
When reassembling, use new cable ties.
5.1.3 Top panel (worktop)
Remove two T-20 Torx screws (with washers) from rear of dryer, slide
panel toward rear of dryer (~ ½ cm) and lift up panel. When
reassembling, place panel over two plastic mounting tabs, slide panel
forward and replace two screws.

5.1.5 Drum and drum cover (with drum bearing)
1) Remove rear panel (5.1.4).
2) To remove belt tension, disconnect belt (from motor pulley).
3) Remove dryer shaft clip and two T-20 Torx drum cover screws,
then lift cover from dryer. Drum cover holds drum rear bearing,
so drum isn’t supported once drum cover has been removed.
4) Drum sleeve bearing can be removed from drum cover by
removing four T-20 Torx screws.
