Setting the Motor Overload Switch
The Motor Overload Setting Switch (Figure 4) adjusts the level of motor overload current protection needed to
protect the motor from damage due to overcurrent conditions. Turn the circuit breaker and disconnect switch
to the off position, and wait 5 minutes. Remove controller access cover. Find the Service Factor Amps on the
motor nameplate (Figure 5). Set the motor overload switch setting as high as possible without exceeding S.F.
Amps shown on motor nameplate. If the Service Factor Amps of the motor does not match any of the Motor
Overload Settings, use the next lowest switch setting.
Caution
Failure to perform this step will result in loss of Motor Overload Protection and will void the
Motor Warranty. Motor damage can occur if this switch is not set properly.
8. Switch Settings With Power Applied
Setting the Pressure
Note
The maximum pressure setting is 85 psi for 3AB2 and 100 psi for 5AB2. DO NOT EXCEED HOME
FIXTURE RATINGS.
Open a faucet in the system and turn the breaker/disconnect switch to the ON position. The pump will start
and pressure will increase to the factory preset 50 PSI. After the pressure has stabilized, use the Increase/
Decrease Pressure Adjust Pushbuttons (fi gure 4) to adjust the pressure setting.
PUSH AND HOLD the Increase (INC) or Decrease (DEC) Pressure Adjust Pushbutton until the desired pressure
setting is reached. Close the faucet and allow the controller to go into standby mode (pump off and solid green
status light). Controller must go into standby for pressure setting to be stored.
