Work out the correct position for the hole for the
float switch. With a corrugated profile tank wall this
is on the upper flat section of the profile as shown
below.
Work out the correct location of the float switch
relative to the pump outlet.
The float switch location should also be:
• At least 40mm above the pump inlet.
• Placed away from the rainwater entry into the tank so that the incoming
flow does not interfere with the operation of the switch.
Before cutting the hole check again that the 5m lead from the float switch
will reach the rainBank
® and plug comfortably into it.
1. drill a 22mm hole in the side of the tank in the
correct position. a hole saw is the best tool for this
job. Ensure all swarf is removed from the hole.
If installing the switch in a corrugated tank you
should make sure that it is installed on the flat
section between the radii as shown below.
2. ensure the compression nut is loosened so that
the sealing grommet is not expanded. Remove
the sealing nut and insert the switch into the hole
as below.
3. the switch will not work properly if it is not
properly orientated. make sure the word
“UP” is seen at the very end of the switch
body. now tighten the compression nut to
expand the seal (as shown below).
4. ensure that the switch is still correctly
orientated. With the word “UP” visible, screw
on and tighten the sealing nut to finish the
installation of the float switch.
