INTRODUCTION
PLEASE TAKE THE TIME TO READ THESE INSTRUCTIONS CAREFULLY AND NOTE HOW
THEY APPLY TO YOUR PARTICULAR POOL AND EQUIPMENT.
IMPORTANT : ALWAYS USE DILUTED ACID. SEE SAFETY & WARRANTY SECTION.
IMPORTANT : ALWAYS USE THE BUFFER DELAY FUNCTION WHEN ADDING BUFFER
(ALKALINITY INCREASER / SODIUM BICARBONATE). THIS WILL REDUCE THE
CONSUMPTION OF BOTH ACID AND BUFFER. SEE PAGE 10
pH level is one of the most important pool balance
parameters for any type of pool. Whether the pool
is ionized, ozone, salt water chlorinated (including
salt chlorinators that use alternative salts such as
magnesium and potassium), liquid chlorine etc, the
pH must be maintained at the correct level for
optimum water quality and algae control.
The pH BOSS takes the hassle out of controlling pH,
by doing the job for you. Whenever the pool
filtration pump is running, the pH BOSS will add
small, frequent doses of diluted hydrochloric acid
to ensure correct pH at all times.
This not only saves you time, but it also takes the
guesswork out of colour matching with pH tests
and reduces chemical usage. In particular, the small
doses will not reduce total alkalinity as quickly as
adding a larger amount of undiluted acid every
week or two.
So the pH BOSS saves you time, frustration AND
money !
Before installing the pH BOSS, the pool water
should be correctly balanced, particularly total
alkalinity. The pH BOSS can be safely used on brand
new pools, including those pools which have high
acid demand for the first few weeks, months and
years of operation.
INTRODUCTION
Take note of the few “do’s and don’ts” and you will
have a simple and trouble free start up.
Bionizer is committed to creating a more healthy
environment… the pH BOSS is one integral
component of our ongoing journey in this
direction.
Other components to advance ourselves along the
path back to a toxic free world include the original
Bionizer Bio-effective ionic pool and spa purifer,
and also the Eco-Oxidizer chemical free pool
oxidizer.
Now for the first time pools are able to stay healthy
and clear without any toxic substances polluting
your swimming environment or your lifestyle. You
are removed from all but the most simple tasks
required for pool care.
If you use a pool care service you can reduce the
time they visit… they are now almost redundant.
Let them visit once a month and sweep the pool,
check the skimmer and add some acid to the pH
reservoir and you do no pool care whatsoever.
This is the Bionizer “Ultimate Solution” to Pool
Care…
and your commitment to help us all return to a toxic
free Planet for your children to enjoy.

SAFETY INSTRUCTIONS - READ
IMPORTANT :
It is important to follow basic safety precautions
when installing and using this electrical equipment,
including the following :
CAUTION :
Your warranty could become invalid should you fail
to observe the following :
1. Ensure you read and follow all instructions.
1. The pH BOSS must be installed and operated as
specified.
2. WARNING - ALWAYS USE DILUTED ACID AT A
RATIO OF NOT LESS THAN 4 PARTS WATER TO
1 PART ACID.
2. Damage due to using undiluted or insufficiently
diluted acid is not covered by warranty.
3. WARNING - Do not allow children to use this
product unless they are closely supervised at all
times. This is to prevent accidental injury.
3. Turn off the power to the pH BOSS before
replacing the peristaltic dosing pump squeeze
tube.
4. Keep all cables and tubes visible and do not bury
them. Also, position them so that they do not get
damaged by lawn mowers, hedge trimmers and
other equipment.
4. The life of the unit will be extended (as with most
other pool equipment) if it is placed indoors or in
an enclosed structure. This is recommended as
sunlight can damage the Liquid Crystal Display on
the face of the control unit. The LCD is covered
within the warranty on a pro-rata basis.
5. WARNING - To prevent electrical shock, acid
spillage or incorrect dosing, replace damaged
cords or tubes immediately.
6. Read these instructions and keep the instruction
manual in a safe place.
5. Always power the pH BOSS from a genuine
Bionizer power adaptor. An incorrect adaptor
could damage the pH BOSS and will void your
warranty.
ACID SAFETY
PLEASE FOLLOW THESE IMPORTANT ACID SAFETY INSTRUCTIONS.
ALWAYS ADD THE ACID TO WATER ALREADY IN THE DRUM. NEVER ADD WATER TO ACID.
3. Top off the drum
with more water.
1. WARNING - always use diluted acid at 1 part acid

pH BOSS INSTALLATION
READ THE DO’S AND DON’TS AND TAKE THE TIME TO INSTALL CORRECTLY.
! If a Salt Chlorinator is installed, fit the pH BOSS
tee BEFORE the Salt Chlorinator cell. The acid
will help to keep the expensive Chlorinator
cells clean.
! If a liquid Chlorine injection system is fitted,
install the tee BEFORE the Chlorine injection
point. The acid will help prevent the Chlorine
injector becoming clogged with calcium.
The pH BOSS can be installed onto a new pool or an
existing pool with minimal pool preparation. Ensure
that the pool is correctly balanced, in particular the
Total Alkalinity.
1. Installing your pH BOSS takes around 30
minutes.
NOTE: Turn off all valves prior to fitting the T-piece
(avoid leaks), and turn them back on again before
switching pool pump back on.
2. Alternatively engage a competent person to do
the job.
3. If installing it yourself you will need :
! PVC pressure glue and primer.
! A fine tooth saw.
4. The Probe/Injection Tee must be fitted on the
pipe that sends water back to the pool after it has
been filtered (the “Return Line”).
! If a Bionizer and/or Eco-Oxidizer is installed, fit
the pH BOSS tee BEFORE the Eco-Oxidizer and
Bionizer Ionizing Pods.
TEE PIECE INSTALLATION
1. For 50mm (2") pipe, cut out a 6cm (2.5") section
of pipe sufficient for the Probe/Injection Tee
piece. For 40mm (1.5") pipe, where the reducing
bushes will be used, cut out a 7cm (2.75") section
of pipe.
2. If the Tee piece diameter is larger than the pipe
then use the 50mm to 40mm reducing bushes
provided by glueing them in place in the Tee
piece before fitting. The pipe should now fit
snugly into the Tee piece.
3. Be sure to install the Tee piece in the correct
direction of the water flow, as per the arrow on
the Tee.
The Tee piece should be installed so that the pH
Probe is within 30O of vertical. (See next page)

The control box MUST be mounted vertically, with
the cables at the bottom, in order to be weather
resistant. Any water ingress due to the unit being
incorrectly mounted is not covered by warranty.
2) Plug the optional AC/DC power adaptor into
one of the two mains power outlets provided on
the Bionizer unit.
1. Choose a position that will allow you to see the pH
BOSS Display easily. Fix the control box in position
using screws at each corner of the box.
3) When connecting to a pool control system,
connect the AC/DC adaptor to a suitable power
outlet on the control system, if available.
NOTE: Make sure that the pH BOSS is positioned
near enough to a power outlet and to the T-piece
and acid drum to allow the power connecting and
sensor cables to reach without straining.
For USA installations, when there is no spare
outlet socket, cut the 110V plug off the AC/DC
adaptor cable, and hard wire to the control system
terminals.
2. Make sure that the unit is undercover and that the
Display is not in direct sunlight as it is not covered
by warranty if it is damaged by sunlight.
3. The pH BOSS should only be powered on when the
pool pump is running. This can be done in 3 ways :
1) Connect the short DC to DC adaptor lead from
SET THE TIMER FOR THIS OUTLET TO THE
SAME SETTING AS THE POOL PUMP OUTLET.

PROGRAMMING YOUR pH BOSS
! Press the PROGRAM / SET button to move through each of the five user settings.
! If no key has been pressed for 30 seconds, the unit will return to the normal readout display. Any changes
will not be saved.
! Use the Up and Down keys to change settings.
! When changing a setting, press PROGRAM / SET after the desired setting is programmed to save the
changes and return to the normal readout display.
! To quit any screen without saving changes, press AUTO / OFF to cancel.
AUTO / OFF KEY
Press to alternatively select Auto, Off and 24 Hrs Off :
AUTO: Unit will dose
acid when pH is
outside the set point.
Buffer Delay: This
function will stop the
unit dosing acid for 6
hours of filtration.
ALWAYS USE THIS FUNCTION AFTER ADDING
BUFFER (ALKALINITY INCREASER / SODIUM
BICARBONATE) TO THE POOL, TO REDUCE THE
AMOUNT OF BOTH ACID AND BUFFER USED.
O F F: Unit will not
dose any acid again
until this setting is
changed.
The AUTO / OFF key is also the “Cancel” key to exit
without saving changes in programming screens.
DOSE SETTING
This setting will move
between 1 and 5.
! Use the ­ and ¯ buttons to enter setting 1 to 5.
! Press PROGRAM / SET save the new setting.
Alternatively, press AUTO / OFF to cancel without
saving.
The dose setting is used to set the acid pump
addition and waiting times, and are related to how
quickly the pool turns over the water. This is related
to both pool size, and pump/pipe setup.
In general, a smaller pool would use a lower Dose
Setting than a large pool. However other factors can
affect this, such as pool turnover time.
10
As a guide, use the following setting as a STARTING
point when the unit is first installed :
1....Up to 75,000 L / 20,000 Gallons
2....75,000 to 150,000 L / 20,000 to 40,000 Gallons
3....150,000 to 250,000 L / 40,000 to 65,000 Gallons
4....250,000 to 500,000 L / 65,000 to 130,000 Gallons
5....>500,000 L / 130,000 Gallons
For pools under 25,000 L (6,500 Gallons), be sure to
dilute the acid at 8 parts water to 1 part acid (page 5).
For pools with a wet edge and balance tank, use a
setting of 1 lower than listed for the pool size.
If the pH BOSS does not keep up with acid demand,
and the Alarm sounds, increase the dose setting by
one step and check in 2 days.
If the alarm is tripped due to low pH, reduce the dose
setting by one step and check in 2 days.
NOTE ABOUT DOSE SETTING FOR NEW POOLS
New concrete/pebblecrete, marblesheen and
quartzon pools can have very high pH level for the
first 1 to 3 months of operation. Readings of pH10 or
even higher are possible. Even when the pH is
brought down to the correct pH7.4, the pH reading
will still drift back up over the following hours or
days.
The acid demand during the initial period could be as
high as 1 Litre (1 Quart) of acid per 10,000L (2,500Ga)
of pool water per day. This acid demand will
gradually reduce over the first 1 to 3 months.
If the pH BOSS is not able to maintain pH at the pH7.4
set point, please increase the Dose Rate setting to a
higher value. This will add more acid in each dosing
cycle, and therefore be able to control the pH during
this high acid demand period of time.
PROGRAMMING YOUR pH BOSS
CHANGING THE pH SET POINT

Please note that the pH BOSS factory preset default
Set Point is pH7.4. This is most likely to be the best
setting for your pool, so changing the Set Point is only
recommended for experienced users.
ALARM FUNCTION
When the Alarm is set to ON, the pH BOSS will sound
the beeper and disable the acid pump when the pH is
above or below the set point for more than 4 hours.
The reason for the alarm being triggered should be
found and rectified too. It could be due to any of the
following :
When the Alarm is set to OFF, the alarm will never be
triggered, regardless of the pH reading. Only
advanced users should set the alarm to OFF, and only
temporarily while the cause of the alarm beeping is
being rectified.
Problem ...Acid drum is empty.
Fix.............Make up a new drum of diluted acid.
Dilution ratio should be at least 4 parts
water to 1 part acid.
Use PROGRAM / SET to select Alarm.
! Use the Use the ­ and ¯ buttons to select On or Off.
! Press PROGRAM / SET to save.
! Press AUTO / OFF to quit without saving changes.

MAINTENANCE
A LITTLE PREVENTATIVE MAINTENANCE WILL HELP YOU GET THE MOST FROM YOUR pH BOSS
pH PROBE CALIBRATION
Approximately every 6 months, the pH Probe should
be calibrated to ensure that the readout is correct.
Calibration is simply the process of placing the pH
Probe into a solution of known pH, and adjusting the
readout to that value.
3. Remove the pH Probe from the Tee
! Unplug the pH Probe from the pH BOSS first. (This
will avoid the cable getting twisted when the pH
Probe is unscrewed. U n s c r e w t h e p r o b e
completely from the Tee.
Calibration frequency is dependent on how many
hours per day the pH Probe has water rushing past it.
! Reconnect the pH Probe connector to the pH
BOSS.
The pH BOSS measures the operating hours each
day, and will display a calibration reminder message
when calibration is due.
! Rinse the probe well in clean water. De-ionized or
distilled water is ideal, but tap water will suffice.
1. Prepare for pH BOSS for Calibration
! If you are using a Bionizer to control the power to
your pool pump and pH BOSS, unplug the pool
pump from the Bionizer Control Unit.
! Leave the pH BOSS connected to the Bionizer.
! (If you are powering the pH BOSS and Pool Pump
from an external power source, please ensure that
the pool pump is switched off and unplugged
during the entire calibration procedure.)
! (Connect the pH BOSS to a power outlet socket,
but do not switch on yet.)
2. Prepare pH7.0 Calibration Buffer
! There are TWO bags of
salt crystals inside the
pH7.0 Sachet. Empty
B OT H bags of those
crystals into the
calibration jar (see picture
on the right).
! Fill the Buffer Jar to the
250mL mark with distilled
water. Filtered tap water
can also be used.
! Replace both the seal and
the lid, then shake well for
1 minute to ensure that
the salts are fully
dissolved.
12
4. Place pH Probe into pH7.0 Buffer
! Place the pH Probe into pH7.0
Buffer, immersing to a depth of
at least 25mm.
! Leave the pH Probe in this
pH7.0 Buffer for at least 10
seconds before proceeding
with the calibration steps
below.
5. Calibration Procedure
! Switch the pH BOSS power on. If it is connected to
a Bionizer, set the Bionizer to Manual:On mode to
switch on the power outlet.
! Press the CANCEL button to bypass the start-up
screen delay.
! Press the PROGRAM / SET button until the pH
Calibration screen is displayed, as per the example
below. The “Pool pH” reading may be 7.0 or
another value, depending on the condition of the
pH Probe and current calibration setting.
! When the reading is stable, press the ­ and ¯
buttons until the Pool pH reading is exactly 7.0.
! Press the PROGRAM/SET button again to lock in
the re-calibrated probe’s setting.
MAINTENANCE
6. Re-fit pH Probe and Power Connections
! Disconnect the pH Probe from pH BOSS (to
prevent twisting the cable) and re-fit into the Tee.
Re-connect the pH Probe to pH BOSS when done.
! Re-connect the pool pump to the Bionizer power
outlet, or the power output to which it was
connected before starting this procedure.
! Switch your pool equipment back on.
! If using a Bionizer, ensure that it is set to “Auto”
mode.
! Press the AUTO/OFF button on the pH BOSS

PUMP SQUEEZE TUBE LUBRICATION
The peristaltic pump squeeze tube should be
lubricated at least once per year, or when the pH
BOSS displays the lubrication reminder message.
You do not need to remove the inlet and outlet hoses
to lubricate the pump squeeze tube.
Hold the top and
bottom of the pump
cover.
DO NOT over-lubricate, as this will attract dirt and
grit, which will cause premature wear of the
squeeze tube and rollers.
WARNING : Use only silicon grease. Petroleum gel
and other oil-based lubricants may cause the
squeeze tube to break down, resulting in corrosive
diluted acid spillage.
Lift up the pump cover
from the bottom side.
Pull out the pump rotor a little, and place the
squeeze tube between the pump body and the two
rollers.
Push the squeeze tube and rotor into the pump
body. Ensure that the inlet and outlet are seated in
the guides on each side of the pump body.
P u l l o ff t h e p u m p
cover.
Remove the Squeeze
tube. The pump rotor
may come out too, but
can easily be pushed
back into place.
Re-fit the pump cover until it clips into place. There
should be no gaps anywhere between the pump
body and cover.
Apply Silicon
grease here.
Apply a THIN SMEAR of Silicon grease to the
squeeze tube and pump rotor shaft as shown
above.

Ensure that the squeeze tube is not pinched on
either side, after the cover is replaced.
PUMP SQUEEZE TUBE REPLACEMENT
If the peristaltic pump squeeze tube breaks or loses
its flexibility for pumping, it needs to be replaced.
Remove the old tube and fit a new tube as per the
lubrication procedure on this page. A replacement
Squeeze Tube can be ordered by telephone or online
at www.phboss.com or www.bionizer.com.au.
