For greater distances between your
rainwater tank and pump, a 10m float
switch (top and side entry) extension
lead (Davey Part No. 14186) will need to
be added. Up to 4 float switch extension
leads can be added between the pump
and the rainwater float switch lead. It
is recommended that the float switch
extension lead/s are in a protective cinduit.
STEP 3a - TOP ENTRY FLOAT SWITCH
NOTE: THE VERTICAL POSITION OF
THE FLOAT SWITCH IN RELATION TO
THE PUMP WATER INLET IS CRITCAL
1. Measure the distance from the top of
the tank (A) to the highest point of the
tank outlet to the pump (B).
2. Mark on the float switch cable a
length equal to A-B minus 200
millimeters or distance (B) to (D).
3. Drill a hole in the top of the tank large
enough to suit a cable grommet or
strain relief grommet (F) - not supplied.
4. Snap off retainer clip (C) from top of
weight (D).
5. Position retainer clip 100mm from
float ball (E).
6. Slide weight (E) over retaining clip
and firmly snap into position.
7. Lower weight into tank and feed top of
cable through hole drilled in Step 3.
8. Fasten with cable grommet to
previously measured length (A) to (B).

manufacturer before drilling.
• The float switch is designed to be
installed from the outside of the tank.
There is no need to get inside the tank.
• The sealing grommet of the float
switch is designed to work in a
