3.10 ATTENTION AFTER SUBMERSION
If the generator has been submerged in water, it must not be started and operated. Following any submersion in water, have a Carrier Dealer thoroughly clean and dry the generator.
3.11OUT OF SERVICE PROCEDURE
3.11.1REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, prepare the generator for storage as follows:
1.Start the engine and let it warm up.
2.Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down.
3.Once the unit has shut down, it will signal a low oil fault.
4.Set the generator's main circuit breaker to its OFF (or open) position.
5.Set the AUTO/OFF/MANUAL switch to OFF and turn
off the utility power to the transfer switch. Remove the 7.5A and 15A fuses from the generator control panel. Disconnect the battery cables as outlined in "General Hazards" (page 2). Turn on the utility power supply to the transfer switch in order to power the
emergency load centers circuits while utility power is available.
6.While the engine is still warm from running, drain the oil completely. Refill the crankcase with oil. See "Engine Oil Recommendations," Section 3.3.1.
7.Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.
8.Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s).
9.Remove the battery and store it in a cool, dry room on a wooden board. Never store the battery on any concrete or earthen floor.
10.Clean and wipe the entire generator.
3.11.2RETURN TO SERVICE
To return the unit to service after storage, proceed as follows:
1.Verify that utility power is turned off and that the AUTO/OFF/MANUAL switch is set to OFF.
2.Check the tag on the engine for oil viscosity and classification. Verify that the correct recommended oil is used in the engine (see Section 3.3.1). If necessary, drain and refill with the proper oil.
3.Check the state of the battery. Fill all cells of unsealed batteries to the proper level with distilled water. DO NOT USE TAP WATER IN THE BATTERY. Recharge the battery to 100 percent state of charge, or, if defective, replace the battery. See "Specifications," Section 1.5, for type and size.
4.Clean and wipe the entire generator.
5.Remove the 7.5A and 15A fuses from the generator control panel. Reconnect the battery. Observe battery polarity. Damage may occur if the battery is connected incorrectly.
6.Open the fuel shutoff valve.
7.Insert the 7.5A and 15A fuses into the generator
control panel. Start the unit by moving the AUTO/OFF/MANUAL switch to MANUAL. Allow the
unit to warm up thoroughly.
8.Stop the unit by setting the AUTO/OFF/MANUAL switch to OFF.
9.Turn on the utility power to the transfer switch.
10.Set the AUTO/OFF/MANUAL switch to AUTO.
11.The generator is now ready for service.
NOTE:
If the battery was dead or disconnected, the exercise timer must be reset,
