Davey RAINBANK WITH SUBMERSIBLE PUMP - Manual (Page 16)

to protect against electrical surges and
lightening strike damaging rainbank ® or
its pump we strongly recommend the use
of a suitable surge protection device and
residual current devices.
STEP 8 - TESTINg
test the operation of rainbank ® .
1. With the mains connected and the
rainwater tank empty turn on one
of the taps in the laundry that feed
the washing machine or flush the
toilet. Mains water should flow
normally. the pump should not turn
on. the ‘status’ light should glow
‘red’ to indicate that mains water is
being used. When this is completed
turn off tap.
2. Fill the rainwater tank with sufficient
water to activate or cover the float
switch.
3. check that the pump is correctly
primed and there are no air locks that
will interfere with its operation as per
the Davey instructions. this is
essential for the proper operation of
the unit. see the instructions on how
to do this for all types of Davey pump
in the priming section on page 26.
4. turn on a tap or flush a toilet in
the rainwater system. the pump
should run and deliver rainwater.
allow to run for several minutes to
clear air from pipes. the ‘status’ light
will now glow ‘green’.
5. remove the float switch connection
from the rainbank ® – this should
stop the pump and confirms that
the float switch and power
connections have been made correctly
– refit the float switch connection. the
‘status’ light will now glow ‘red’.
press the manual override button
to operate the pump if needed. the
‘status’ light will glow ‘yellow’
while the manual override button is
depressed.
note: Mains water indicator light is
not applicable in rainbank ® ‘s’
models.
6. check for leaks around rainbank ® , the
pump, pipework and fittings.
INSTAllATION TYPE 2
Above ground tank with submersible
pump inside eg: KRBS1&2
IMPORTANT
• this type of pump comes with its own
float switch system to detect water
level so it is not necessary to drill the
tank to fit a float switch.

INSTAllATION TYPE 1
Above ground tank and pump
outside tank. Suitable kit models:
KRB1,2,3&4
tools you will need
• adjustable spanner 2” or 50mm
(across flats)
• second adjustable spanner 2” or
50mm (across flats)
• thread tape
• 20mm spade bit or hole saw to drill
hole in top of tank for float switch.
• If you are mounting the rainbank ®
to a wall as a bare installation you
will need the Davey rainbank ® wall
mounting bracket
(part number 32556).
STEP 1 - PUMP POSITION
evaluate and select the best pump site.
this must be below the lowest anticipated
level of the float switch and this level
should be at least 100mm above the base
of the tank to avoid sludge being drawn
into the pump.
the pump site should be well drained and
have a firm base. a concrete slab 600mm
x 600mm is ideal.
STEP 2 - RAINBANK ® POSITION
Work out where the rainbank ® will be
positioned.
check that there is a power point within
reach of the 3 metre power lead.
IMPORTANT
Do not use long mains power extension
leads as they cause substantial voltage
drop, poor performance and can lead to
motor overload.
check that the float switch lead
(9m long) will reach the rainbank ® .

Installation Inside Buildings: to
cater for possible plumbing leaks or damage
to the rainbank ® system components, the
installation must include an enclosure that will
capture any water spraying from the plumbing
or rainbank ® system and direct it into a
properly constructed drain tray.
!
Note: When installing a rainbank ®
and/or associated pump system inside a
building, allowance for possible high pressure
leakage Must be made.
!
Note: In order to carry out routine
maintenance to the rainbank ® Must be easily
accessible to the end user or home owner.
