PWP2 Ioniser
Instruction Manual
DESCRIPTION
The PWP2 provides a filtration pump timer and uses an ionisation process of passing a
controlled current through the water between the co
pper and silver alloy electrodes. This
process called electrolysis enables copper and silver ions to enter the water. T
he copper
works to inhibit algae growth and the silver as an aid to fighting bacteria.

INSTALLATION INSTRUCTIONS
CONTROLLER MOUNTING
Find a suitable location to mount the
control box. As with all pool equipment, it
should be installed out of direct weather
and no closer than 3 meters from the
water’s edge and a minimum 600mm of
the ground. 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. Note that direct sunlight
will fade the display over a period of time.
Connect the pump to the 240VAC outlet at
the bottom of the pwp2 and connect the
cell housing leads to the cell housing
wing-nuts, polarity is not important. The
cell housing is to be plumbed after any
heating equipment and with the cell
house openings facing the ground.

ELECTRODE REPLACEMENT
When the electrodes erode to about
10mm in diameter it is time to replace
them. Turn the power off to the PWP-2,
undo the two electrode cable wing nuts,
close any appropriate valves if the
electrode housing is below water level
then unscrew the large retaining nut on
the side of the housing. Gently prize the
black electrode carrier from the housing
then undo the two brass electrode
retaining nuts, use a cloth or gloves to
handle spent electrodes. Fit replacement
electrodes ensuring that two of the flat
surfaces are parallel to one another and
the brown silicon gaskets are located in
the carrier correctly, fit washers and
tightening nuts firmly. Align the carrier
locator and fit into the housing then
tighten lock nut. Open any closed valves
and switch on power – check for leaks and
tighten as required.

OPERATING INSTRUCTIONS
CONTROLLER INFORMATION
The pool water purifier PWP2 is suitable
for swimming pools, spas and ponds up-
to 100,000 litres for a standard unit.
The filter pump and ionisation is
controlled for up-to 2 run times per day
and will remember the settings
indefinitely and the clock will remain
accurate if the power is switched off for a
period of up-to 10 days. The PWP2 can
be used on interrupted power supplies
(e.g. tariff 33 in QLD).
The ions active L.E.D. indicates that the
ionisation process is working. The polarity
L.E.D.’s indicate the polarity of the output
current applied to the electrodes, the
polarity will change every 15 minutes to
allow the electrodes to wear evenly.
WATER BALANCE
On new pools the conductivity of the
water can be low so it may take some
weeks to obtain a copper reading. As the
copper level increases the conductivity
will also increase and the copper level will
start to rise faster. It is fine to start on
250mA but you will need to monitor the
copper levels every couple of weeks and
when the level has started to rise towards
0.4ppm start reducing the Ions Output.
Copper levels can climb quicker with salt
pools as the conductivity of the water is
higher. Filter run time and Ions Output
can both be used to achieve correct
copper levels. If the copper level in the
water exceeds 0.6ppm turn the Ions
Output to Zero. Water balance should be
checked at least weekly during the
swimming season and monthly over the
winter period.
Total Alkalinity 100 - 150 ppm
Water pH 7.4 - 7.8
Copper 0.4 – 0.5 ppm
Chlorine – 1.0ppm Plus
Water balance should be checked at least
weekly during the swimming season and
monthly over the winter period. Without
regular checking of the water balance and
the addition of pool chemicals, copper
may become unsettled and can plate out
of solution, causing staining on the
swimming pool surface – the
manufacturer and the dealer of the PWP-
2 bares no responsibility for such staining
as pool water chemistry is the
responsibility of the pool owner/s.

The above recommended times will also
be dependent on whether or not a
standard pool pump is being used or an
energy efficient variable speed pump.
3) IONS OUTPUT
IONS OUTPUT
SET FOR xxx mA
When you enter the IONS OUTPUT menu
you may change the current output for
ionisation, adjust according to copper
levels as determined by a water quality
test. Copper (Cu) should be in the range of
0.4 – 0.5 ppm. If the level of copper is
below 0.4 ppm then increase the current
output, if it is above 0.5 ppm then
decrease the current output, if it is above
0.6 ppm then set the current output to
0mA.
4) SEASON MODE
When the season mode menu is selected
the following is displayed;
SET SEASON MODE
SUMMER MODE/ WINTER MODE
SUMMER MODE is the normal operation of
filtration, 2 cycles per day. When selecting
WINTER MODE you will be prompted to
select the start month of winter and the
start month of summer. At the start of
winter the 2
nd
filter cycle is automatically
disabled to allow for reduce filtration
requirements in the off-season, when the
summer month start the 2
nd
filter cycle
will automatically be re-applied. You can
also start winter mode in August and
finish in March if required (i.e. for Northern
Hemisphere). Hint: the two filter cycles
can be overlapped so if cycle 1 is from
10am-2pm and cycle 2 is from 8am to
4pm then in winter mode the time is
reduced by 2 hours at the start and end.
