NOTE: For protection, the Davey
®
pump motor is tted with an automatic
“over temperature” cut-out. Constant tripping of this overload device
indicates a problem e.g. low voltage at pump, excessive ambient
temperature (above 50°C) in pump enclosure.
WARNING: Automatic reset thermal overloads will allow the pump to restart
without warning. ALWAYS disconnect the pump motor from the electrical
supply before maintenance or repairs.
