How Your Tumble Dryer Works
The tumble dryer uses heated air to dry loads of
laundry.
1. When the motor is started, the exhaust fan pulls
room temperature air in through the air intake at the
rear of the tumble dryer and over the heat source
(burner flame for gas, heating element for electric, and
coil for steam).
2. The heated air moves into the cylinder, where it is
circulated through the wet load by the tumbling action
of the cylinder.
3. The air then passes through the lint filter, exhaust
fan, and is vented to the outdoors.

Section 4
Grounding
Grounding Instructions
This tumble dryer must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing the path of least
resistance for electric current. This tumble dryer must
be connected to a grounded metal, permanent wiring
system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the
appropriate ground location.
NOTE: To ensure protection against shock, this
tumble dryer MUST be electrically grounded in
accordance with local codes, or in the absence of
local codes, with the latest edition of the National
Electrical Code ANSI/NFPA No. 70. In Canada the
electrical connections are to be made in accordance
with CSA C22.1 or the latest edition of the
Canadian Electrical Code, Part I and/or local codes.
Electrical work should be done by a qualified
electrician.
To reduce the risk of fire and electric shock, check with a qualified serviceperson for proper
grounding procedures. Improper connection of the equipment grounding conductor may
result in a risk of electric shock.
W068R1
WARNING
To reduce the risk of fire and electric shock, if electrical supply is coming from a three phase
service, DO NOT connect a “High Leg” or “Stinger Leg” to a single phase machine. On a three
phase machine, if there is a “High Leg” or “Stinger Leg” it should be connected to L3.
W069
WARNING
All electrical connections should be made
by a qualified electrician.
To reduce the risk of electrical shock, de-
energize the electrical circuit being
