Shutting Down The Unit; Using The Water Supply - Generac Power Systems Magnum MTT25 Operating Manual

SHUTTING DOWN THE UNIT

Check with personnel using power supplied by the unit and let them know the power is going to be turned off. Make
sure the power shut down will not create any hazards by accidentally turning off equipment that needs to be kept on
(pumps, compressors, lights, etc.).
When you have finished using the unit, proceed with shut down as follows:
1. Remove any loads from the generator output connection lugs and receptacle panel.
2. Switch the individual circuit breakers for each light (A) to the OFF (O) position.
3. Switch the generator main circuit breaker and receptacle panel main circuit breaker (B) to the OFF (O) position.
4. Push ENGINE STOP (C). Pressing the red Engine Stop button will result in the unit going into the shutdown
cycle and starting a 15 second shutdown timer called stop value. If the unit does not shut down within 15 seconds,
a stop fail alarm will be displayed on the Liquid Crystal Display (LCD) window.
5. Turn the Control Power switch (D) to the OFF (O) position.
Always switch all circuit breakers to the OFF (O) position to prevent starting the generator
