As the PH3 is a maintenance free and self-checking valve, it does not require any specific operator
involvement. The PH3 performs an anti-foul cycle every time the engine comes to a stop after a period of
running. However if the unit is stored for extended periods, or run for extended periods without pause, it
is imperative that the engine run and shut down monthly so that the PH3 valve can perform its anti-foul
cycle.
