BUT overload
protector
TRIPS.
Under no circumstances should the elctrician rating of the overload protector
be increased or the protector BY-PASSED in an attempt to break free a seized
pump. Motor failure invariably results and the warranty is void.
ELECTRICAL TEST : Consult an electrician for all electrical testing.
VOLTAGE TEST : Voltage should be within 10% of the motor nameplate. If more
or less, consult your Hydro company.
AMPERAGE TEST : Locked motor-rotor AMPS is 4-5 times normal Amps. IDL
AMPS-Less than normal Amps. Pump may be sand locked-pull and clean.
RESISTANCE TEST : if ohmmeter reading is high, the circuit is open. Low
reading indicates there is a ‘‘short circuit’’. Situation must be corrected and
further check of all wiring is in order.
WARNING : Serious or fatal shock may result from the failure to ground all
metal plumbing and the motor to the power supply ground when pump is on
the outside of a drilled well. Do not install pump in lake around swimmig areas.
