SERVICE CHECKLIST
ELECTRICAL PRECAUTIONS -
Before servicing a pump, always shut off the main power breaker and then unplug the pump - making sure you are wearing
insulated protective sole shoes and not standing in water. Under flooded conditions, contact your local electric company or a qualified licensed electrician for disconnecting
electrical service prior to pump removal.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions.
Allow 2-1/2 hours after disconnecting before attempting service.
