B e f o r e you even touch the
m o t o r, MAKE SURE THE
POWER IS OFF. Always turn the power off at the
electrical service entrance fuse or breaker box, to
p revent possible electric shock. To prevent electrical
shock when touching the motor, be sure windings and
capacitor are securely grounded to the ground term i n a l
which should be used in conformity with local codes.
D o n ’ t work on electrical operations if water or moist
conditions cannot be avoided. If the motor is not
operating pro p e r l y, refer to the following guide.
MOTOR FAILS TO STA RT (makes no sound)
1 .Check the obvious first — are the power switch
and timer on?
2 .Be sure fuses are of proper size and type, then
check for a blown fuse or tripped circuit bre a k e r.
3 .Be sure the motor is connected correctly (as shown
on motor nameplate), but first — TURN OFF THE
POWER. Check the terminal screw to see if it was
tightened onto wire insulation instead of the wire
itself. Verify that the ground wire is firmly
connected to the green ground scre w.
4 .Check the voltage at terminal board after first
TURNING THE POWER BACK ON. Be sure you turn
the POWER BACK OFF after completing this step.
NOTE: Voltage at motor terminals should be ±10%
of voltage on nameplate. If the voltage is high
( m o re than ±10% above nameplate number),
consult the local power company. If the voltage is
low (±10% below rated voltage), check the size of
the power line from fuse box to motor. If the
