Davey SJ60-08PC Automatic Water Pressure System - Manual (Page 7)

Trouble Shooting Check List continued...
PUMP STOPS, BUT RESTARTS QUICKLY - NO FLOW DEMAND (AUTO MODELS ONLY)
1.
Leaking suction line, checkvalve or footvalve.
2. Suction pipe too long and/or too flexible.
PUMP DOESN’T SUPPLY ADEQUATE PRESSURE
1.
Suction lift is too high.
2. Pump impellers partially blocked.
3. Jet blocked.
4. Partially blocked suction line.
5. Wrong pump selected.
6. Change the installation.
NOTE: For protection, the pump motor is fitted with an automatic “over temperature” cut-out. Constant
tripping of this overload device indicates a problem eg. low voltage at pump, excessive temperature (above
50 o C) in pump enclosure.
During servicing, use only approved, non-petrochemical based oring and gasket lubrication. If unsure, consult
your Davey Dealer for advice.
Care should also be taken when servicing or disassembling pump to avoid possible injury from hot
pressurised water. Unplug pump, relieve pressure by opening a tap on the discharge side of the pump and
allow any hot water in pump to cool before attempting to dismantle.
WARNING - When servicing or attending pump, always ensure power is switched off and lead unplugged.
Electrical connections should be serviced only by qualified persons.
