Owner's Manual

ADJUSTING THE PRESSURE SWITCH (ALTHOUGH SHOULD NOT BE NECESSARY).

• ADJUSTING THE PRESSURE SWITCH. Should the pressure 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 counter clockwise to decrease. The screw should not be

adjusted more than one turn without consulting the Factory. Excessive adjustment of the pressure

switch could cause low system pressure, and rapid ON/OFF cycling, reducing pump and motor life.

Damage may also occur if recommended maximum pressures are exceeded. The Warranty does not

cover improper adjustment of the pressure switch.

• Rapid On/O Cycling must be limited to no more than 6 times per minute, even if the pump is operating

in the Continuous Duty zone. Cycling could cause the motor to heat beyond the recommended

maximum temperature, and reduce the operational life of the pump and pressure-sensing switch.

SERVICING:

• Every Year: Check system against operating standards. If continuous duty, replace lower housing assembly

• Every Other Year: Check against operating standards. If continuous duty, replace motor

• Every Fifth Year: Replace valves
