Unplug the Pump from its electrical outlet before performing any
inspection, maintenance, or cleaning procedure.

TO AVOID INJURY: Do not use pump if any part of the switch housing or
probe (inside switch housing) is cracked, broken or missing.
Maintenance
1. If the pump is moved during operation, flush
pump with clean water after every use.
2. Quarterly
Perform at least once every 3 months under
optimal conditions. For frequent use or dirty
areas, more frequent maintenance is required.

Possible Causes
For technical questions, please call 1-888-866-5797.
e. Lift Pump from 2" or more of water to determine
that pump turns on/off as intended.
Note: If the pump won't stop, unplug the pump.
Remove the Debris Strainer and check
inside the sensor body. Remove any
trapped leaves, debris or dirt.
3. When the temperature drops below freezing,
remove the pump from service and store indoors
to protect pump from ice damage. The pump
has a protection circuit to protect the motor from a
locked impeller which can be caused by debris build
up or a frozen impeller. When the pump is activated
and the impeller is detected to be locked, the unit
will automatically shut down to protect the motor
from overheating. Once the pump is able to operate
correctly, the pump will resume normal operation.
Possible Solutions
1. Remove Debris Strainer. Clean out dirt and
debris from Debris Strainer, inlet screen
and impeller. Replace Debris Strainer.
2. Check for kinks, reposition and straighten.
Flush any clogs with clean water.
3. Reduce discharge height.
1. Consult an electrician.
2. Wait for water level to reach 2"
or move Pump to a lower location.
3. Have a qualified service technician repair or replace.
1. Rinse switch with clean water.
2. Reduce discharge height.
1. Replace check valve. Move hose so output
runs downward, away from pump.
2. Reposition pump so it sits level on surface.
3. Rinse switch with clean water.
