Operating Instructions and Parts Manual
TROUBLESHOOTING (CONT'D)
5. 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 is 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 our de la sonde est fissuré, cassé ou manquant.
