Trouble Shooting Check List
a) 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.
b) PUMP SWITCHES ON AND OFF FREQUENTLY (CYCLING) -
Pressure
Pumps Only
1. Check that tank air pressure is correct - see above.
2. Leaking taps, float valves etc. check plumbing.
3. Leaking check valve/foot valve.
c) MOTOR DOESN’T START WHEN SWITCHED ON.
1. Power not connected.
2. Supply voltage too low.
3. “Over temperature” cut-out tripped.*
4. Motor not free to turn eg. a jammed impeller.
5. Internal motor fault.
Maintenance
The only regular attention your new pressure system requires is to check the
pressure tank’s air charge every 6 months. This can be checked at the air
valve with a tyre gauge. Do not charge tank to a higher pressure than 168kPa
(XJ Ultra) or 196kPa (XJ70P & XJ90P).
To check air pressure in tank:
1. Switch off pump.
2. Open outlet nearest to pump to release
water pressure.
3. Remove air valve cap from top of
Supercell tank and charge tank to 168kPa
(XJ Ultra) or 196kPa (XJ70P & XJ90P)
using air pump and check with tyre
gauge.
4. Switch on.
5. Close outlet.
Please pass these instructions on to the operator of this equipment.
Priming and Operation
1. Fill pump and suction line (on
flooded suction, simply open gate
valve to pump). When full, fit
Supercell
Pressure Tank
or Priming
Plug as
applicable.
2. Ensure outlet nearest to pump is
open.
3. Ensure all valves in suction line are
open and switch on.
4. Prime should establish almost
immediately and a strong flow
of water should be
evident from the
outlet. Allow water to
flow for 10-20 seconds
to expel air then close
outlet.
5. Automatic Pressure
Pumps will shut down automatically
within several seconds. Manual
systems must be switched off at
the power point.
6. If no flow is evident from tap,
switch off at power point and repeat
from step 1 ensuring there is an
adequate supply of water available
to the pump.
Never operate your Davey Dynajet ® pump for more than a few
seconds without discharge flow.
*NOTE: For protection, the Davey 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 45 o C) in pump enclosure.
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 the pump to cool before attempting to
dismantle.
During servicing, use only approved, non-petrochemical based oring
and gasket lubrication. If unsure, consult your Davey Dealer for advice.
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.
NOTE: Prior to installation remove the red transport plugs from the suction and/or discharge.
In accordance with AS 3350.2.41 we are obliged to inform you that this
pump is not to be used by children or infirm persons and must not be
used as a toy by children.
