Cautions & Warnings
3
!Please read the instructions fully and keep
this manual on hand whenever operating
or maintaining your pH Drive.
!Always use diluted acid. Concentrated
acid will cause damage to the squeeze
tube and fittings, which are not covered
by the warranty.
See page 6 for information on the safe
handling and dilution of acid.
!DO NOT add acid into a drum that
previously contained liquid chlorine until
that drum has been rinsed three times
with fresh water. Ensure that the label on
the drum indicates that the drum contains
acid.
!As for all pool equipment and chemicals,
the pH Drive should be installed out of
reach of children. Children must not have
access to operating the pH Drive without
adult supervision.
!Although the pH Drive has a weather
resistant design, its service life will be
considerably longer if it is not exposed to
direct sunlight and rain. Wear and tear
from direct exposure to the elements is
not covered by the warranty.
!Do not allow grass or weeds to grow
around the pH Drive, or the tubing and
cables to prevent accidental damage from
garden trimming equipment.
!Any damaged cables must be replaced
immediately to prevent electrical shock.
!Unplug the pH Drive power lead before
servicing or changing the dosing pump
cassette.
!The pH Drive must be serviced only by an
authorised service agent. Please contact
your Maytronics Authorised Dealer for
det ails. Despi te being low-voltage
powered, opening the unit may still cause
an electric shock, which can cause injury or
death.

POOL pH
SET POINT
INFORMATION LINE
This is the readout of the current pH of your pool.
The pH Drive maintains the pool pH at the programmed Set Point.
This is where pH Drive indicates helpful messages and warnings, so you know what’s happening
at all times.
pH is OK.........................................The current pH of the pool is within the Set Point. No dosing is
required at this time.
Adding Acid (or Base) ..............The pH Drive is operating the dosing pump to add acid or base to
correct the pH of the pool back to the Set Point. The default setup of
the pH Drive is to add acid.
pH Alert! Reset:Enter ..............The pH of the pool has been above the Set Point for 4 hours or more,
without returning to the Set Point. Press Enter to reset the alert timer.
24 Hr Delay..................................The user has selected the 24 Hour Delay function. This is normally
used when buffer or other chemicals have been added to the pool,
which can temporarily change pool pH. The 24 Hour Delay function
prevents excessive usage of acid or base.
Acid (or Base) Pump is Off ....The user has set the dosing pump to being totally off, regardless of
the pool pH reading.
Mixing Time Delay....................After the dosing pump has added a quantity of acid or base, the pH
Drive will switch it off for some time. This allows the added acid or
base to mix through the pool before adding more, if required.
Cool Squeeze Tube ..................The dosing pump has stopped for a short time to allow the squeeze
tube to cool down.
Startup Time Delay ..................The pH Drive has just been switched on, and is waiting for its pH
reading to become stable, before doing any automatic control.
pH is Out of Range....................The pH Drive has detected that the pool pH reading is extreme and
needs to be checked.
pH Calibration Due ...................12 months has passed since the last time that the pH Drive was
calibrated. Calibration ensures that pool pH readings are accurate.
Change Pump Cassette .........The dosing pump has operated for 50 hours or more, which is time for
the pump cassette to be replaced. This is important maintenance.

Acid Dilution Procedure
1. DO NOT add acid into a drum that
previously contained liquid chlorine, until
that drum has been thoroughly rinsed
three times with fresh water.
2. Fill a 20 or 25 Litre dangerous goods
certified drum to around half way with
fresh water.
3. Add 5 Litres of concentrated Hydrochloric,
Muriatic or Non-Fuming acid to the drum.
Pour slowly to prevent spillage.
4. Top up the drum with more fresh water. Do
not overfill.
5. Replace the drum lid and swish around to
mix the acid well with the water. Keep this
drum lid fitted until the diluted acid drum is
in position.
Additional Information
!Always use acid to at least 3 parts water to
1 part acid. Damage from undiluted or
insufficiently diluted acid is not covered by
the warranty.
!Always add acid to water. Never add water
to acid.
!The acid drum must be below the level of
the non-return valve in the pH Tee when
installed. This prevents acid syphoning into
the pipeline.
!Fit the Acid Drum label supplied with your
pH Drive to your drum of diluted acid. This
will identify its contents and shows the
dilution instructions.
Acid Safety & Dilution
6
Maytronics recommends using pre-diluted acid purchased from your
reputable pool shop or service agent.
Alternatively, this section provides information on the safe handling
and dilution of acid to use with your pH Drive. Please take the time to
read and understand this section, to prevent injury or illness due to acid
spillage.
Safety Information
!Dilute acid in a well ventilated area,
preferably outdoors.
!Have a supply of fresh running water (e.g.
a garden hose) readily to hand, in case of
spillage.
!Wear protective clothing, safety goggles
and gloves when diluting acid.
!Use only a Dangerous Goods certified
drum. Your pool store can advise on this.
!If an acid spillage does occur, wash down
well with copious amounts of fresh water
immediately. Seek Medical advice if any
acid burn has occurred or if breathing is
affected.

pH Sensor Calibration
14
The pH Drive will display a reminder to
calibrate the pH Sensor approximately every
12 months:
The pH Sensor should be calibrated to ensure
that the readout is correct. Calibration is
simply the process of placing the pH Sensor
into a solution of known pH, and adjusting
the readout to that value.
The pH Drive can be calibrated in one of two
ways:
1. Inline Calibration
This is done by obtaining an accurate pH
measurement of the pool water and
adjusting the readout to that value.
2. pH7.0 Buffer Calibration
This involves removing the pH Sensor
from the pH Tee, placing it into a pH7.0
Buffer solution, and adjusting the readout
to 7.0.
Inline Calibration
1. Measure the pH of the Pool
Set the pH Drive to Standby or 24Hr Delay
mode an hour or more before measuring
the pH of the pool. Do not change back to
Au to Control mode until af ter pH
calibration is completed.
Ensure that the pool filtration pump has
been running and no acid has been added
for at least 1 hour prior to doing an Inline
Calibration. This is to ensure that the pH
level is stable throughout the whole pool.
Measure the pH of the pool with a good
quality, calibrated pH meter. Alternatively,
take a sample of pool water to a pool shop
which has an electronic pool balance
measurement system. A standard pool pH
test kit is NOT accurate enough to be
relied upon for pH calibration.
2. Calibration Procedure
!Press Setup to enter the user-friendly
menu system, then press ‡ and ˆ until
Calibrate pH Sensor is selected.
!Press Enter to go to the Calibration screen.
The current reading is displayed in
brackets. The flashing “X” indicates that
the reading is not yet stable. DO NOT
calibrate until the “X” changes to a “ü”
!Press ‡ and ˆ to set the “Cal:” pH value to
the pH of the pool, as measured in step 1.
!Press Enter to calibrate the pH Sensor, or
press Cancel to quit without calibrating.
!Set the pH Drive back to Auto Control
mode.
Calibration Failure
If pH calibration fails, the pH Drive will display
this message:
!C l e a n t h e p H S e n s o r a s p e r t h e
troubleshooting section, then retr y
calibration.
!If the calibration failure persists, the pH
Sensor will most likely need to be replaced.
pH7.0 Buffer Calibration is on the next page.

pH7.0 Buffer Calibration
The pH Drive is powered from your Ozone
Swim unit. The pH Drive will need power for
calibration, but with the pH Sensor removed
from the pH Tee, the pool pump must not be
running. You will therefore need to unplug
the pool pump from the Ozone Swim unit.
1. Prepare pH7.0 Calibration Buffer
! A sachet containing 2 ziplock
bags of salt was supplied with
your pH Drive. Simply pour
BOTH sachets into the 250mL
bottle and fill to the 250mL
mar k w i t h d eio nis e d o r
distilled water. Shake well
until all salts have dissolved.
!This solution will last up to 6
months after it has been
made, providing it is not
contaminated and is stored in
a cool, dark place
2. Remove the pH Sensor from the Tee
! Disconnec t the pH Sensor to avoid
straining the cable and plug when
removing the sensor from the pH Tee.
Unscrew the sensor completely from the
Tee.
! Reconnect the pH Sensor to the pH Drive.
! Rinse the sensor well in clean water. De-
ionized or distilled water is ideal, but tap
water will suffice.
3. Place pH Sensor into pH7.0 Buffer
!Decant a small amount of
pH7.0 buffer into a clean cup.
Place the pH Sensor into this
buffer, so it is immersed to
15mm or more, as per the
diagram on the right.
!DO NOT place the pH Sensor
directly into the 250mL
bottle of pH7.0 buffer.
4. Calibration Procedure
! Switch the pH Drive on by activating the
pool pump output of the Ozone Swim unit.
! Press Setup to enter the user-friendly
menu system, then press ‡ and ˆ until
Calibrate pH Sensor is selected.
!Press Enter to go to the Calibration screen.
The current reading is displayed in
brackets. The flashing “X” indicates that
the reading is not yet stable. DO NOT
calibrate until the “X” changes to a “ü”
!Press ‡ and ˆ to set the “Cal:” pH value to
exactly 7.0.
!Press Enter to calibrate the pH Sensor, or
press Cancel to quit without calibrating.
5. Re-fit pH Sensor and Power Connections
! Disconnect the pH Sensor from the pH
Drive to avoid straining the cable and plug
when screwing into the pH Tee. Re-fit into
the pH Tee. Re-connect the pH Sensor to
the pH Drive when done.
! Re-connect the pool pump to the Ozone
Swim power outlet.
! Switch your pool equipment back on.
Calibration Failure
If pH calibration fails, the pH Drive will display
this message:
!C l e a n t h e p H S e n s o r a s p e r t h e

buffer, so it is immersed to
15mm or more, as per the
diagram on the right.
!DO NOT place the pH Sensor
directly into the 250mL
bottle of pH7.0 buffer.
4. Calibration Procedure
! Switch the pH Drive on by activating the
pool pump output of the Ozone Swim unit.
! Press Setup to enter the user-friendly
menu system, then press ‡ and ˆ until
Calibrate pH Sensor is selected.
!Press Enter to go to the Calibration screen.
The current reading is displayed in
brackets. The flashing “X” indicates that
the reading is not yet stable. DO NOT
calibrate until the “X” changes to a “ü”
!Press ‡ and ˆ to set the “Cal:” pH value to
exactly 7.0.
!Press Enter to calibrate the pH Sensor, or
press Cancel to quit without calibrating.
5. Re-fit pH Sensor and Power Connections
! Disconnect the pH Sensor from the pH
Drive to avoid straining the cable and plug
when screwing into the pH Tee. Re-fit into
the pH Tee. Re-connect the pH Sensor to
the pH Drive when done.
! Re-connect the pool pump to the Ozone
Swim power outlet.
! Switch your pool equipment back on.
Calibration Failure
If pH calibration fails, the pH Drive will display
this message:
!C l e a n t h e p H S e n s o r a s p e r t h e
troubleshooting section, then retr y
calibration.
!If the calibration failure persists, the pH
Sensor will most likely need to be replaced.
pH7.0 Buffer Calibration
The pH Drive is powered from your Ozone
Swim unit. The pH Drive will need power for
calibration, but with the pH Sensor removed
from the pH Tee, the pool pump must not be
running. You will therefore need to unplug
the pool pump from the Ozone Swim unit.
1. Prepare pH7.0 Calibration Buffer
! A sachet containing 2 ziplock
bags of salt was supplied with
your pH Drive. Simply pour
BOTH sachets into the 250mL
bottle and fill to the 250mL
mar k w i t h d eio nis e d o r
distilled water. Shake well
until all salts have dissolved.
!This solution will last up to 6
months after it has been
made, providing it is not
contaminated and is stored in
a cool, dark place
2. Remove the pH Sensor from the Tee
! Disconnec t the pH Sensor to avoid
straining the cable and plug when
removing the sensor from the pH Tee.
Unscrew the sensor completely from the
Tee.
! Reconnect the pH Sensor to the pH Drive.
! Rinse the sensor well in clean water. De-
ionized or distilled water is ideal, but tap
water will suffice.
3. Place pH Sensor into pH7.0 Buffer
!Decant a small amount of
pH7.0 buffer into a clean cup.
Place the pH Sensor into this
buffer, so it is immersed to
15mm or more, as per the
diagram on the right.
!DO NOT place the pH Sensor
directly into the 250mL
