NOTE: If the pressure level is consistently low, check for any leakage at air cells or
connecting tubes. If necessary, replace any damaged cells or tubes or contact local
qualified dealer for repair.
If the control unit is equipped without audible alarm feature, the Low Pressure Indicator will
flash until the low-pressure fault condition is solved. If the control unit is equipped with
audible alarm feature, the Low Pressure indicator will flash and the alarm will sound when
air pressure is below normal (preset pressure). To silence the alarm, simply press the alarm
mute button, and it will be silent for 3 minutes; however, the Low Pressure Indicator still
remains flashing. After 3 minutes, alarm buzzer will alert again if the pressure has not yet
returned to normal.
4.7 Power Failure Alarm
If the pump unit has a sudden power outage during normal use, the power indicator LED on
the control panel will flash " yellow" light, and alarm will sound. To silence the alarm, simply
press Power button on the control panel.
When power failure situation occurs, alarm will last until backup battery is low or it can be
turned off by manual operation.
Once power failure alarm situation is resolved, it is recommended to turn "OFF" the main
power switch located at the lateral side of the pump. If the main power switch is not turned
"OFF", once the main power comes back again, the pump will start again at "Standby" status.

cleaning.
