Automatic start-up. Disconnect mains power and render the equipment inoperable before attempting repairs or maintenance.
Read instruction manual.
Read and understand manual completely before using this equipment.
Only qualified service personnel may install, operate, and maintain this equipment.
Follow proper shutdown procedure for cooling if generator is running. Failure to do so may create a burn hazard.

Two lead wires deliver 120V electrical power to th e heater from the T1 and Neutral terminals at the custome r connection panel.

Preparing for Installation

Automatic start-up. Disconnect mains power and render the equipment inoperable before attempting repairs or maintenance.

NOTE: Follow shutdown procedure in owner’s manual if generator set is running.
Proceed as follows before performing any maintenance to prevent the generator set from accidental startup:

1. Lift lid, press OFF mode button on control panel, and allow unit to cool completely.

2. Set MLCB (generator disconnect) to OFF (OPEN) position.

3. Remove 7.5A DC fuse.

4. Turn off utility (mains) power supply to transfer switch.

   • In service rated transfer switches, turn main breaker OFF.
   • In non-service-rated switches, turn power feeder breaker OFF.
     NOTE: The T1, T2 (if applicable), N1, and N2 fuse s could be removed from the transfer switch by an electri-cal contractor instead of turning off the normal power cir-cuit breaker.

5. With generator set shut down, remove controller fascia (2013–2015 units) or intake side panel (2016 and newer units), and front panel.

6. See Figure 1 or Figure 2. Remove customer con-nection panel cover (A).

5. Proceed to Connecting Lead Wires.

500/1000 Series Engines

1. See Figure 6. Remove airbox cover (G), intake elbow (H), and air filter (I).

2. See Figure 7. Remove three mounting screws behind engine divider panel to disconnect snorkel (J).

3. See Figure 8. Remove screws from airbox base (K).

4. See Figure 9. Remove screws attaching mixer to intake manifold (access screws behind divide r panel). Set airbox base and mixer (L) aside, with wires still connected to mixer, to expose breather hose (M).
   NOTE: See Figure 10. For units with the 1000 Series engines (2016–Present), the lower mixer screw is acces-sible through a hole (N) in the engine divider panel. Remove plastic cover from the hole and set aside for reassembly.

5. See Figure 11. Wrap breather heater (P) aroun d breather hose, evenly spaced as shown, with lead wires at the bottom. Wrap breather heater and hose with silicone tape (provided) to secure heater.

7. Secure all wires with plastic wire ties at least 0.5 in (1 cm) away from fuel hoses.

8. Install mixer with air box base and snorkel.

9. Install intake elbow, air filter, and air box cover.

10. Proceed to Connecting Lead Wires.

Connecting Lead Wires

2016–Present Units

1. See Figure 12. Pass lead wires through the customer connection panel grommet (A).
2. See Figure 13. Connect heater lead wires to T 1 terminal (B) and Neutral stud (C) as shown. NOTE: Wire with ring terminal connects to Neutral ba r stud.
