PILOT VALVE ADJUSTMENTS
All adjustments made to the pilot valve must be performed by a qualified technician. The adjustments must
be made while the unit is operating, therefore, extreme caution must be taken while working on the unit.
Observe all necessary precautions. Always use a back-up wrench and make all differential and unload pres-
sure adjustments in very small increments (1/8 turn).
WARNING !
The pressure switch and / or pilot valve are set at the factory for maximum e󰀩ciency. Adjustments to either com-
ponent must be performed by a qualied technician. Exceeding the factory recommended maximum pressure
will void the warranty and may cause personal injury.
