AUXILIARY PUMP – ELECTRICAL CONNECTION
The auxiliary pump, if installed, must be wired to the control board. The flexible
cord supplied with the pump must be housed in a 20 mm flexible conduit. The
flexible conduit should be secured to the insulated pipe work with the cable ties
provided, to the side of the solar storage tank using the adhesive backed cable
tie mounts and cable ties provided and to the penetration in the solar storage
tank jacket using the cable gland provided.
It is necessary to make a penetration in the jacket of the solar storage tank,
30 mm to the right of and aligned with the mid height point of the lower front
cover, to accommodate the flexible cable and conduit. The penetration, 20 mm
in diameter, can be made using a hole saw, suitable for cutting through 0.5 mm
thick Colorbond. The edge of the penetration is to be smoothed off after
forming to ensure there are no sharp edges. Refer to the diagram for position.
Auxiliary Pump Wiring Connection Jacket Penetration
Warning: The removal of the lower front cover will expose 240 V wiring.
Switch off the electrical supply at the isolating switch to the water heater before
removing the lower front cover and if necessary disconnecting the ribbon cable
from the solar control module.
Connect the active plug from the auxiliary pump to the terminals marked
“PUMP 2” on the control board (refer to
“Wiring Diagram” on page 47) and the
earth wire spade connector from the auxiliary pump to a terminal on the earth
connector strip located on the bracket adjacent to the control board.
