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:
• 15 seconds after it detects "no water", the pump will stop
operating,
• The 'PUMP ON' LED will go out, and
• The 'WATER FAILURE' LED will begin flashing.
Restart: Make sure that the suction line is not obstructed,
and that it is connected to a water source.
• Press and release the 'RESET' button.
• The 'PUMP ON' LED should light up, and
• The 'WATER FAILURE' LED should stop flashing.
If flow is adequate, the pump will operate until 15 sec-
onds after it reaches the set-point pressure and the flow
stops.
High Temperature: When the water temperature inside the
pump reaches 158°F (70°C),
• The pump will stop operating,
• The 'PUMP ON' LED will go out, and
• The 'TEMPERATURE FAILURE' LED will begin flashing.
Restart: Wait 20 minutes to let the water temperature
drop below 104°F (40°C):

• Make sure that the pump is supplied with water and that
the flow is unobstructed.
• Press and release the 'RESET' button.
• The 'PUMP ON' LED should light up, and
• The 'TEMPERATURE FAILURE' LED should stop flashing.
• If not, let it cool some more and retry
NOTE: If the pump continues to run hot, shut it off and
call Customer Hot Line at 1-800-942-3343.
LUBRICATION
The motor is lubricated at the factory for the life of
the bearings. The pump seal is water cooled and self
lubricating.
PUMP SERVICE
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 pre-
vent damage and will reset after the motor cools. If the over-
load trips repeatedly, check the pump for the cause (low volt-
age, a clogged impeller, etc.).
CORRECTIVE ACTION
DISCONNECT POWER; Replace fuse or reset circuit breaker.
Plug into 115 Volt grounded outlet.
Check voltage being supplied to pump.
Check that impeller moves freely and is not clogged.
Re-prime according to instructions.
Stop pump, shut off water, and change filter cartridge. Filter should be
installed on discharge side of pump.
Open valve.
Re-pipe using pipe of the same size as suction and discharge ports on pump.
Clean impeller.
Thaw pipes.
Replace with plastic or new steel pipe.
Re-pipe using pipe the same size as suction and discharge ports on pump.
Enlarge inlet pipe; check well pump system.
Make sure outlet is at 115 Volts.
