Air Conditioning Operation
n For best results, the SMART throttle switche should be in the off position.
n Bring the generator to normal operating temperature before applying the air
conditioning load. Always allow a 2 minute wait period when manually cycling an
air conditioner off and on.
n A longer wait period may be required under unusually hot weather conditions.
n Additionally, all other loads should be turned off until the air conditioner has
started and is performing normally. It is also important to follow the air conditioner
manufacturer's instructions for starting and restarting for proper operation.
n Some air conditioner manufacturers offer a start capacitor or rapid start kit. The
lack of a start capacitor can cause the air conditioner to draw too high a starting
current and overload the generators. Contact your air conditioner dealer if you
consistently have problems starting your air conditioner.
n This generator is not generally recommended for air conditioners exceeding
13,500 BTUs.
Low oil alarm system
The low oil alarm system is designed to prevent engine
damage caused by an insufficient amount of oil in
the crankcase. Before the oil level in the crankcase
falls below a safe limit, the low oil alarm system will
automatically shut down the engine (the engine switch
will remain in the ON position).
If the low oil alarm system shuts down the engine the red
low oil alarm indictor light will come on when you operate
the starter, and the engine will not run. If this occurs,
search for any oil leaks. Add engine oil to resume normal operation.
SMART Throttle
When the SMART throttle is placed in
the on position, engine speed is kept at
idle automatically when the electrical
load is disconnected and returns to the
proper speed required by the electrical
load when the load is reconnected.
The engine speed varies according to the amount of load applied to the generator.
Placing the smart throttle in the on position is recommended to minimize fuel
consumption and engine noise while in operation.
n The Smart-throttle system does not operate efficiently if the electrical appliance
will be used in a rapid on-off or low-to-high rpm mode.
n When high electrical loads are connected simultaneously, turn the Smart-throttle
switch to the OFF position to reduce voltage fluctuation or shutdown.
n In DC operation, turn the Smart-throttle switch to the OFF position. When the
Smart throttle is in the off position, the engine runs at rated load RPM.
