Pressure Sensing Demand Switch
The PowerFLO Series 7800 pump is controlled by
a built-in pressure sensing demand switch. When a
faucet or valve is opened downstream of the pump, line
pressure drops, thus starting the pump automatically.
Conversely, when the valve shuts, the line pressure
increases, turning the pump off automatically.
The pressure switch actuates in response to the
pump outlet pressure at a predetermined and preset
pressure. The pump label indicates the predetermined
ON and OFF pressures. Typically, the OFF pressure
is accurately set at the factory and the ON pressure is
within an allowable range below that value.
These pressure settings may vary in response to the
characteristics of the system in which the pump is
installed, the flexibility and length of the tubing, the
faucet or valves and the duration that they are open.
Therefore, variation in pressure setting is expected
with use and over time.
Adjusting the Pressure Switch
Should the pressure sensing demand switch OFF
setting vary with use and time to an unsuitable value,
it may be adjusted for optimum performance. Turn
the set screw clockwise to increase the OFF pressure
setting and counterclockwise to decrease the setting.
The screw should not be adjusted more than one-half
turn without consulting the factory. Excessive
adjustment of the pressure switch could cause low
system pressure, rapid cycling ON/OFF operation, and
reduced pump and motor life. Damage may occur. The
Warranty does not cover improper adjustment of the
pressure switch.
