INSTALLATION INSTRUCTIONS
CONTROLLER: Find a suitable location to mount the control box*
installed out of direct weather and no closer than 3 meters from the water's edge. Lift up the two
mounting tabs and use two appropriate screws to mount the control box to the wall, keeping in mind
that the power cable is 1.8m long and should be plugged directly into a general power outlet, not into
an extension lead. Do not drill through the box.
SOLAR PUMP: The solar pump plugs into the left side 240Vac socket marked as PUMP. Note that the
solar pump can only operate when the FLOW switch detects water flow.
FLOW SWITCH: The Flow switch is fitted in the PVC pipe after the filter and before the take-off T; it
must be mounted at the top of the pipe with the arrow matching the direction of water flow. If a
pressure switch is used it must be mounted before the filter.
TEMPERATURE SENSOR: The pool temperature sensor must be fitted into the suction line of the
filtration pump, as close to the pool as practical, preferably in a position out of direct sunlight. It is
recommended that a 14.5mm hole be drilled in the PVC pipe, this can be carried out using a Dontek
PD01 grinding drill or a small pilot hole can be drilled and a 14.0mm drill-bit used spinning in a
counter clockwise direction to minimize the chance of shattering pipe. Insert the grommet into the
pipe and gently push in the blue sensor barb. The blue sensor plug is to be fitted to the plug socket
marked POOL, in some cases there is some benefit to cable tie 30cm of wire from the pool
temperature sensor to the pipe and insulate this section (some ambient differences can travel up the
tinned copper wire and affect the sensor reading).
All temperature sensor cables must NOT be run parallel to power cables and should never
be cable tied to power cables. All cable run lengths should be less than 50m if possible. Cable ties
should be used to fasten the sensor cable to the cold water inlet pipe making sure that the ties are
approximately 10mm from PVC fittings. Cable ties should be tightened only firm, over tightening can
cause breaks in the outer PVC if not careful. If the cable is to be run under ground a conduit must be
used to protect the wire and there is to be no cable joins within, conduit ends must be sealed to
prevent water ingress.
Any excess cable should be removed and re-fitted ensuring that the wire ends are tinned
with solder.
REMOTE TEMPERATURE ROOF SENSOR:
The roof temperature sensor must be fitted into a small piece of solar collector or equivalent and
attached to the roof. The best location is within an arms length of the gutters edge of the house or
shed as long as the sensor end is not shaded and is on a roof of similar aspect of the main collector. It
must not be fitted on top of the solar collector or fitted to high points on the roof like Ridge Capping
as false readings will be detected.
This unit has been designed to eliminate the need to run a temperature sensor cable from the solar
controller to the roof; this is replaced by a solar powered transmitter that transmits the roof
temperature. The roof temperature sensor cable is connected on the inside of the radio remote
temperature transmitter in a screw in socket. Test for site suitability (*
remote temperature transmitter on the gutter ensuring the solar panel (PV) faces north and the
antenna points up (Vertical), if the antenna faces down then water may enter the box through the
power entry / sensor entry hole and void the warranty.
*RADIO NOTE: RADIO TRANSMITTER SPECIAL CONSIDERATIONS:
Do not permanently fix the radio transmitter until good reception is achievable (See site test); do not
mount the Aquasun 3 in a position where reception of radio signals may be difficult, avoid mounting
near other electrical equipment (try a site test with a FM radio or Mobile phone).
The range is 100m with no obstructions and with no interference from other transmitters or sources of
electrical noise. Transmission may not occur through objects such as steel, aluminium, re-enforced
concrete and large bodies of water (e.g. pump room under a pool). Line of sight is the ideal situation
but not always possible, the antennas should always remain vertical. Echo cancellation or ghosting
may occur, which will prevent the signal being received reliably. If the Aquasun 3 is to be installed in a
metal shed there may be reception issues and the controller may need to be optioned with a remote
antenna or moved outside.
