TING INSTRUCTIONS
WHEN DOES THE PUMP STOP OPERATING?
Pressure Set-Point/No Flow:
The pump will stop operating and the ‘Pump on’ LED will go off
several seconds after:
• The system pressure is above the starting pressure.
• The flow has stopped.
This is normal operation.
Restart:
A water flow in the system greater than 1/4 U.S. GPM (0.95 L/min) or a drop in pressure
below the starting pressure set-point will cause the pump to restart and the ‘Pump on’ LED to
light up. The pump will continue to operate until several seconds after:
• It reaches the maximum pressure of the pump.
• The flow stops.
The delay in shutting off the pump prevents rapid cycling when water faucets are being turned on
and off quickly (for example, when brushing teeth, etc.)
Pressure Drop/No Flow:
Normally, when the pump starts, it will very quickly generate pressure
and sense flow. If there is no flow and the pressure does not rise, it senses a “no water”
condition. It can also sense this during operation if the water supply to the pump fails. To protect
the pump from running dry:
• Several seconds after it detects “no water”, the pump will stop operating.
• The ‘Pump on’ LED will go out.
• The ‘Failure’ LED will go on.
Restart:
Make sure that the suction line is not obstructed, and that it is connected to a water
source.
• Press and hold the ‘Restart’ button for 5 seconds.
• The ‘Pump on’ LED should light up.
• The ‘Failure’ LED should go off.
If flow is adequate, the pump will operate until several seconds after it reaches the set-point
pressure and the flow stops.
Lubrication
The motor is lubricated at the factory for the life of the bearings. The pump seal is water-cooled
and self-lubricating.
NORMAL OPERATION OF THE PUMP
Fill the pump with water before starting it.
Make sure that the pump has been properly installed and primed, and that the suction pipe is unobstructed
and open.
Plug in the pump. The ‘Power on’ and ‘Pump on’ lights will come on indicating, respectively, that voltage is
present and that the pump is ready to operate.
The pump will start and will continue to operate until several seconds after the system pressure has risen
and flow has stopped.
WARNING!
Risk of burns. NEVER run the pump dry. Running the pump without water may cause pump to overheat and
cause burns to persons handling the pump. It may also damage the impeller and may damage the seal,
causing leaking or flooding, and will void the warranty.
Hazardous voltage. Can shock, burn, or cause death. Unplug the pump and controller before servicing
them. Do not handle the pump or controller or attempt to work on the pump with wet hands or while
standing on a wet or damp floor.
The motor has an auto-reset thermal overload protector. If the motor overheats, the overload will cut off the
power to prevent damage and will reset after the motor cools. If the overload trips repeatedly, check the
pump for the cause (low voltage, a clogged impeller, etc.)
