SL8RR 2PUMP – INSTRUCTIONS

DESCRIPTION:

The SL8 RR 2PUMP is a swimming pool controller that heats a swimming pool by pumping pool water through solar
collector panels.
If solar gain is available the solar system will heat the pool to the solar limit (sol limit). Solar has a time lockout that
prevents heating outside of the time set (default 09:00 – 19:00, see note 5).

CONTROLLER MOUNTING:

The controller enclosure must be firmly attached to a nearby solid fixture by either the two mounting lugs or direct
attachment though the controller. If mounting through the controller ensure the power cord is disconnected from the
mains supply then remove the enclosure front cover by turning the four corner locks so each arrow points to the 'O'
marked on the front cover. Insert two mounting screws diagonally through the oval holes in the enclosure, refit front
cover and turn the four corner locks to the 'I' position.
The power cable is 1.8m long and should be plugged directly into a general power outlet, not into an extension lead.

CIRCULATING PUMP(S):

The solar circulating pump plugs into the right hand 240Vac socket marked as SOLAR PUMP. The left hand 240Vac
socket marked as AUXILIARY will control the second pump which starts 3 seconds after the SOLAR PUMP. The
maximum combined current is 10 AMPS 2400W.

FLOW SWITCH:

This controller is not fitted with a flow switch, instead its hard wired internally to have permanent flow, be aware that a
message will appear for 30 seconds indicating that it is waiting for prime 30 before solar start-up.
Temperature SENSORS:
The pool sensor must be fitted into the suction line of the solar boost pump, preferably in a position out of direct
sunlight. For retro-fit systems the pool sensor must be fitted in the suction line before the take off Tee fitting for the
solar boost pump. 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
black sensor barb. The green sensor plug is to be fitted to the plug socket marked POOL.
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 roof temperature transmitter that only transmits when in direct sunlight, and
a receiver that calculates the roof and pool temperature turning on the solar pump when required.
As the unit operates in a UHF radio band, reflections and moving objects can cause a transmission to be corrupted
with a subsequent indication "ROOF SIGNAL NOT RECEIVED" on the display. Up to 10 transmissions can be missed
(and last valid reading is kept for 10 minutes) before pump action will occur and the solar pump will turn off. If this
occurs, and if the solar conditions are still favorable, the solar pump will not turn on again and resume normal
operation unless it has received a valid transmission.
The remote roof transceiver obtains its operating power from a solar panel, it will not operate if there is no sun or if
there is significant cloud cover. Obviously solar heating would not occur in such conditions.
Due to the possibility of reception ghosting and electrical interference the Transmitter may be required to be moved to
an alternative position, this may be as little as two meters and keep in mind that the roof sensor cable may be
extended 20 meters if required. The main controller should be mounted away from other electrical appliances as far as
possible to reduce the chance of interference. If the unit 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. A Power substitute cable
is supplied for installation testing on cloudy days – Simply clip a 9Volt Transistor Battery onto the Battery Snap
supplied and substitute the left hand green plug marked PV. Remember to refit original plug when testing is over.
