The plug end of the level switch connects into the base of the RainBank in the
2.5mm Miniature Audio DC power socket adjacent to incoming power lead.
The level switch itself is designed to allow for installation into the tank wall from
the outside, with no need to gain internal access.
The level switch is
suitable for installation
in polyethylene, steel
and fibreglass tanks.
Installation in steel tanks
may require extra care to
ensure swarf and debris
do not damage the tank
coating. If installing the
device in a corrugated
steel tank, you should
ensure it is installed on
the flat section between
the radii, as illustrated
below.
The level switch should
be installed at least
40mm above the height
of the tank outlet. It
should also be placed
away from the rainwater
entry into the tank, so that
the incoming flow during
rainfall periods does not
cause interference with
the level switch.
The level switch can be inserted via a circular hole of 22mm diameter. The use
of a hole saw is recommended for this task. Ensure all swarf is removed from the
hole, including the internal surface of the tank.
Ensure the compression nut is loosened, so that the sealing grommet is not
expanded. Remove the sealing nut and insert the level switch into the hole (as
shown below).
STEP 2
Insert Float
Ensure the level switch is correctly orientated, and the word ‘UP’ is seen on top at
the very end of the switch body. Now tighten the compression nut to expand the
seal inside the tank (as shown below).
STEP 3 - Tighten
Compression Nut
Ensure the level switch is still correctly orientated, and the word ‘UP’ is seen on
top at the very end of the switch body.
While maintaining the orientation of the switch, screw on and tighten the sealing
nut to finish the installation of the float switch.
