Davey RAINBANK WITH SUBMERSIBLE PUMP - Manual (Page 9)

rainbank ® does not need maintenance
but there are things you can do to ensure
its most reliable operation.
• Fit a “first flush” system that ensures
the first run of dirty rainwater does not
go into the tank.
• clean your gutters and first flush
devices and ‘Y’ strainers regularly.
• remove branches that over hang your
roof.
• have a strainer fitted to your rainwater
tank inlet and regularly check this for
leaves and twigs, etc.
• You should also check for debris in
the bottom of your tank a few times a
year and clean this out if necessary. a
first flush system will greatly reduce
the need for this action.
IMPORTANT MAINTENANCE
PRECAUTIONS
• Davey pump motors are fitted with an
automatic thermal overload switch
that stops the motor if the motor
gets too hot to avoid damaging it.
this automatically re-starts the motor
when the temperature within the
pump has dropped to a safe level.
constant tripping of this switch
indicates a problem e.g. low voltage
at pump, etc.
• this automatic thermal overload
switch can start the pump without
warning. always disconnect the
controller and/or pump motor from the
electrical supply before maintenance
or repairs.
• care should also be taken when
servicing or disassembling pump to
avoid injury from hot pressurised
water. unplug the pump, relieve
the pressure by opening a tap on the
discharge side of the pump and allow
any hot water to cool before
attempting to dismantle.
• Do not use petroleum based fluids or
solvents (e.g. oils, kerosene,
turpentine, thinners, etc on the plastic
or seal components).
• Do not use hydrocarbon based or
propelled sprays around the electrical
components of the controller.
• During servicing use only approved
non petrochemical based oring and
gasket lubrication. If unsure consult
your Davey dealer for advice.

should not be used to interconnect as
part of a bore water, dam water,
grey water, stormwater or recycled
water system without appropriate
additional back flow.
• Make sure the wiring, plumbing and
the rainbank ® unit are protected
from access by children and pets.
Other things we recommend to
maximise the performance and
serviceability of your RainBank ® .
• Fit a first flush system to the guttering
if possible to divert the initial run of
water from the roof that may contain
dirt and pollutants.
• Fit a strainer to the top of your tank
inlet to stop leaves entering the
system.
• Fit a 1 inch ‘Y’ strainer with 200
micron mesh to the pipe work
between the pump and rainbank ® .
this will ensure that debris from
the tank will not build up inside
rainbank ® , washing
machines or toilet cisterns.
• use at least 20mm or 3 ⁄4 inch
plumbing to and from rainbank ® to
reduce the effect of pipe friction.
galvanised pipe not recommended.
