Start Pulse Requirements
All control types will consider a pulse valid if it is between 10
and 1000 milliseconds in length, with a minimum of 25 millisec-
onds between pulses.
Grounding Instructions
NOTE: To ensure protection against shock, this ma-
chine MUST be electrically grounded in accordance
with the 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 connec-
tions are to be made in accordance with CSA C22.1 lat-
est edition Canadian Electrical Code, or local codes.
Electrical work should be done by a qualified electri-
cian.
This machine must be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric shock by
providing a path of least resistance for electric current. This ma-
chine 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.
• Metal conduit and/or BX cable is not considered ground.
• Connecting the Neutral from the electrical service box to the
tumble dryer ground screw does not constitute a ground.
• A dedicated ground conduit (wire) must be connected be-
tween the electrical service box ground bar and machine
ground screw.
WARNING
To reduce the risk of electrical shock, de-energize
the electrical circuit being connected to the tumble
dryer before making any electrical connections. All
electrical connections should be made by a qualified
electrician. Never attempt to connect a live circuit.

CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dan-
gerous operation. Verify proper operation after serv-
icing.
