When provided, separate Controllers should be located adjacent to the Isolator and care
taken to ensure correct connections to the terminal block. The controller isolator must be
'off' during connections.
2.4 LOW WATER LEVEL PROTECTION
Water level sensors are unnecessary when there is no risk of
draw down to the pump.
CAUTION
SunFlo-A
A paddle type float switch is provided on the main pump cable that is suitable for large
diameter well installation where there is sufficient space for paddle operation.
If installed in a borehole the paddle should be removed by cutting the cable and the
three cable ends bared, joined together and bound by insulation tape to the main
drop cable. Care should be taken to ensure a tight connection so the switch leads are
in closed circuit.
SunFlo-B
The total length of cable used for water level sensors should not
exceed 200m.
CAUTION
The water level sensor should be installed not less than 100mm
above the pump suction.
CAUTION
A separate level probe is provided that should be connected to the Controller as
indicated. When fitted it is important to set the timer delay on Switch B (see section
4.2) to protect the pump from cycling as the water level rises. When no low level
sensor is fitted terminal COM1 and WH should be directly connected with a looped
cable.
2.5 HIGH WATER LEVEL TANK SENSOR
A high level sensor is also provided that can be used to control the pump when the
pump output is delivered to a high level tank. In the event of this being fitted it should
be connected to the terminals as shown in Fig 6 and also the timer delay controlled by
Switch B must be set to approx. 20 mins.
3. BATTERY SYSTEMS
SunFlo-S and SunFlo-B installations can be provided with auxiliary batteries to
provide extended pump operation. Batteries must be connected through the
controller provided to the terminals indicated. They should not be connected directly
to the pump. Batteries should be sized according to the table below:
