Where freezing may be a problem, all pipework should be buried and/or insulated (lagged) to prevent this
happening. Your Davey pump should be housed in an enclosure which does not experience temperatures
below freezing (32
o
F).
Trouble Shooting Check List
MOTOR RUNS WHEN SWITCHED ON BUT DOES NOT PUMP
1.
Suction line and pump body not filled with water.
2.
Air leaks in suction lines or suction pipe not under water.
3.
Air trapped in suction lines (also possible with flooded suction due to uneven rise in piping: eliminate
humps and hollows).
4.
No water at source or water level too low.
5.
Valve on suction lines closed.
PUMP WORKS FINE AT FIRST, THEN FLOW DROPS SUBSTANTIALLY
1.
Blocked filters - check to ensure all filters (if installed) are clean and free from blockage.
2.
Flow may be limited from source (eg. too small a supply line and/or inadequate flow). Install a holding
tank before the pump if the source cannot be improved.
MOTOR DOESN’T START WHEN SWITCHED ON
1.
Power not connected or no power available from supply outlet.
2.
Supply voltage too low - check supply voltage.
3.
Incorrect supply voltage (eg. HS20-65Y2 is 230V only).
4.
“Over temperature” cut-out tripped - switch off, wait 10 minutes and switch on again.
5.
Motor not free to turn - eg. a jammed impeller.
6.
Internal motor fault.
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 pressurized water. Unplug pump, relieve pressure by opening a tap
on the discharge side of the pump and allow any hot water in the 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.
WARNING: Do not use hydrocarbon based or hydrocarbon propelled sprays around the
electrical components of this pump.
Motor normally operates at high temperature and may be too hot to touch. Before
handling pump or motor, stop motor and allow it to cool.

FREEZING CONDITIONS: In situations subject to freezing, drain water
from pump & pipework to avoid damage not covered under guarantee.
