cut off leaving approximately 12
"
inside the junction
box. (See fig. 10).
STEP 10. Go to the fan motor and connect the wires
as shown in appropriate wiring diagram. (See fig. 9).
Route the wire from the motor through the junction
box, anchor securely, and cut leaving approximately
12
"
in the box. (See fig. 10).
STEP 11. For the power source, it will be necessary
to route from the fuse/circuit breaker box to the
junction box in the attic space. To accomplish this, it
will be necessary to add a circuit breaker. An alternate
method is to use an existing electrical source already
in the attic space. With either method, route this wire
to another hole in the junction box and cut off leaving
approximately 12
"
of wire in the box. YOU SHOULD
NOW HAVE THREE SEPARATE LINES (WIRES) IN THE
JUNCTION B0X, ONE FROM THE SWITCH LOCATION,
ONE FROM THE FAN MOTOR AND ONE FROM THE
POWER SOURCE.
STEP 12. Using wire nuts connect all wires as
shown in the wiring diagram. It will be necessary to cut
off some of the excess wire in the switch and junction
boxes since these wires must be placed inside these
boxes with the covers anchored securely in place.
When the switch is installed in the switch box BE SURE
THAT THE WALL SWITCH IS IN THE OFF POSITION.
STEP 13. Return to the attic. MAKE CERTAIN THAT
THE FAN BLADES ARE CLEAR AND THAT NO WIRES
OR OTHER OBSTRUCTIONS ARE NEAR THE BLADES.
STEP 14. Verify all electrical connections. Switch
power ON at the Fuse/Circuit Breaker Box.
NOTE: WINDOWS IN AT LEAST ONE ROOM OF
STRUCTURE MUST BE OPEN BEFORE TESTING THE
FAN.
STEP 15. TESTING THE FAN. (See fig. 9). Turn
the switch on to High, allow the fan to run for several
seconds, then turn the switch to Low.
STEM 16. With the fan operating, return to the attic
and observe the fan. If the V-Belt is vibrating, turn
OFF the fan, and switch the power at the Fuse/Circuit
Box to the OFF position. See the SAFETY RULES on
page 1. Move the fan spring to the end hole of the
motor-mounting plate. (See page 7). After repositioning
the spring, switch the power at the Fuse/Circuit Breaker
Box to the On position. Re-test the fan.
STEP 17. After testing, replace the insulation around
the plenum and new framing.
