TROUBLESHOOTING (CONT’D)
6. If the pump cycles on and off too often the electronic switch
may need cleaning. Disconnect pump from power source, remove
the strainer and turn the pump upside down. The sensor probe
will be visible inside the switch housing. Clean inside the housing
gently scrubbing with a small brush using soapy water. Then rinse
thoroughly with clean water.
7. When temperatures drop below freezing remove pump from
service and store indoors to protect pump from damage due to ice.
The pump has a unique protection circuit to protect the motor from a
locked impeller condition possibly caused by debris buildup or from a
“frozen” impeller situation caused by ice formation. When the pump
is activated and a locked impeller condition is detected the unit will
automatically shutdown to protect the motor from overheating. The
pump will continue this on/off cycle for a period of time to attempt to
“free” the impeller until eventually the unit will remain off for a period of
12 hours checking twice a day for a “freed” impeller. Once the pump
is able to operate correctly the pump will resume normal operation.
To reset this delay without waiting 12 hours momentarily unplug the
pump.
Do NOT use pump if any part of the switch
housing or probe is cracked, broken or missing.
Ne PAS utiliser la pompe si une partie du
boîtier de l’interrupteur ou de la sonde est fissuré, cassé ou manquant.
