WARNING: Generac transfer switches should be installed by a professional electrician familiar with electrical wiring and codes, and experienced in working with generators. Generac
accepts no responsibility for accidents, damages or personal injury caused by incorrect installation. This transfer switch is intended for surface mounting OUTDOORS only. Our transfer
switches are UL listed to UL 1008 and meet the criteria of National Electrical code Article 702.6 for Optional Standby Systems. CAUTION: If using the generator and transfer switch for
larger appliances, such as electric water heaters, clothes dryers, electric ranges and small air conditioners, check the labels on the appliances to be sure they do NOT exceed the rating
of the generator. No appliance should have an amperage rating that exceeds the individual breaker rating in the transfer switch (20 or 30 amps). CALIFORNIA PROPOSITION 65

OPERATION AND MAINTENANCE PROCEDURES TO AVOID HAZARDOUS VOLTAGES. TURN OFF THE MAIN CIRCUIT BREAKER IN THE LOAD CENTER BEFORE STARTING INSTALLATION.
Model 6375 – 15 amp Furnace Transfer Switch
1. Furnace transfer switch can be installed to the left or right side of load center. See Figure 3. Trial fit the unit, holding up to the wall about 18" from the
center of the load center, and mark the location of the transfer switch and end of harness at load center.
2. Remove the load center cover. CAUTION: dangerous voltages present inside load center. Locate and remove a ½" KO from the bottom of the load
center where marked in Step 1. Insert harness wires from transfer switch thru KO and install conduit fitting.
3. Remove and retain the two screws that secure interior assembly to the transfer switch enclosure.
4. Lift and pull out interior assembly to provide access to the four (4) mounting holes at the back of the enclosure. Mount transfer switch enclosure in
desired position using installer-provided fasteners through the four (4) mounting holes in back of enclosure. Re-install interior assembly into enclosure
(be sure not to pinch any wires between the enclosure and interior assembly) by hooking the top of the interior assembly deadfront over the studs on
the inside of the enclosure and securing the interior assembly to the enclosure with the two screws removed in Step 3. You are now ready to connect
the transfer switch wires to the desired circuit inside the load center.
5. Turn OFF the circuit breaker in the load center that you want to connect to the transfer switch. Loosen the screw that secures the wire into the circuit
breaker and remove the wire from the circuit breaker.
6. Insert the RED (UTIL) wire from the transfer switch into the circuit breaker and tighten screw.
7. Using a wire connector, connect the wire removed from the circuit breaker in step 5 with the BLACK (LOAD) wire coming from the transfer switch.
8. Insert and tighten the WHITE (neutral) wire from the transfer switch into the NEUTRAL bar in the load center. Insert and tighten the GREEN (ground)
wire from the transfer switch into the GROUND bar in the load center. If there is no ground bar, insert and tighten it into the NEUTRAL bar.
9. Reinstall load center cover. Turn on circuit breaker turned off in step 5. Transfer switch is now ready for testing and operation.
