Resetting of the High Pressure Cut Off Switch (Manual Reset)
If the pressure in the unit surpasses the limit set by the manual reset high pressure
cut off switch, the switch will "trip" and shut down the unit. To reset the high
pressure cut off switch, after the cause of the excessive pressure problem is
identified and corrected, follow the procedures listed below.
1. Locate the high pressure cut off switch.
2. Depress and release the red button to reset the switch.
The automatic reset high pressure cut off switch will also "trip" when the pressure
within the unit surpasses the preset limit. However, it will reset automatically
when the pressure within the unit drops below the set pressure.

wires to assure correct reconnection after the new switch has been
installed.

correct size wrench.
6. Verify that the new high pressure cut off switch is rated the same as the
switch that is being replaced.

the port. Follow recommendations contained in the manufacturer's
