READ THESE INSTRUCTIONS COMPLETELY!
For use with NuTone RF-49, RF-59, RF-68,
RF79, RF85, GF-900 and GF-1200 Series
Roof and Gable Fans only.
Caution: Before attempting to replace fan
thermostat, be sure to switch power off at service
panel and lock service panel to prevent power from
being switched on accidentily. If service panel
cannot be locked securely, fasten a prominent
warning device, such as a tag to the service panel.
1. Disconnect electrical power to the fan at the
breaker box.
2. Locate the wiring box/thermostat enclosure in the
attic near the fan. Use flat blade screwdriver under
edge of cover to remove cover from box. For early
production units, with square wiring box, remove
screw and lift off cover.
3. Inside the wiring compartment, disconnect the
black, white and green ground wires coming from
the house supply. Remove the supply wires from
the wiring box. If the supply cable is secured to the
wiring box with a box connector, remove the nut
securing the box connector to the wiring box.
Remove the cable and box connector and save nut
for reuse.
4. Locate the wires, in the wiring box, coming from the
fan motor. Disconnect the black and white wires. In
early production models a green colored ground
wire from the motor is used. Disconnect this ground
wire from the wiring box. If a box connector is used
to secure the motor cable to the box, remove the
nut securing the connector and remove the cable,
saving the nut for reuse. For models with a plastic
snap-in strain relief bushing, compress the bushing
with a pair of channel lock pliers and remove from
the wiring box. For later production units, depress
tabs on either side of the cable connector and
remove connector and cable from the wiring box.
Replacement Thermostat
MODEL RFTH-95
5. Remove old wiring box/thermostat enclosure from
its mounting surface and mount the replacement
box and thermostat in its place. If the old box
cannot be easily removed, the new box can be
mounted next to the old box. Make sure the supply
wiring and motor wiring is long enough to reach the
new box. Remove the cover from the new wiring
box.
6. Connect the motor wiring to the new wiring
box/thermostat enclosure using the box connector,
strain relief bushing, or cable connector removed in
step 4 above.
7. Reconnect the house supply cable to the wiring
compartment.
8. Wiring connections should be made using
approved twist on wire connectors. Secure the
house supply green or bare ground wire under the
green ground screw in the wiring box. If the fan
motor is supplied with a green ground wire, connect
this ground wire along with the house supply
ground under the green ground screw in the wiring
compartment. Connect the white wire from the
motor to the white house supply wire. Connect the
black wire from the fan motor to one of the black
wires coming from the thermostat. Connect the
black house supply wires to the other black wire
coming from the thermostat.
9. Replace the cover on the wiring box/thermostat
enclosure. Restore electrical power at the breaker
box.
10. Fan operation may be checked by turning the
thermostat down to the lowest temperature setting.
(Attic temperature must be at least 60 degrees F to
test in this manner) It is recommended that the
thermostat be set for approximately 110 degrees F
for normal operation.
