INSTALLING THE pH PERISTALTIC PUMP MODULE:
Refer to the procedures described in the “Davey Peristaltic Pump AS Series”, Installation and Operating
Instructions.
NOTE: INSTRUCTIONS FOR DILUTING POOL ACID
The ChloroMatic Salt Water Chlorinator with pH control, automatically doses a diluted acid solution into the pool
when the pH level needs to be reduced. The peristaltic pump draws this diluted acid from a container in which the
solution is mixed.
Use the table below to determine what water/acid ratio is recommended for your pool, in an approved 20 litre
Hydrochloric Acid container.
IMPORTANT: KEEP BARE HANDS AWAY FROM POOL ACID AND ALWAYS USE CAUTION WHEN
HANDLING POOL CHEMICALS.

Note: These ratios are based on Hydrochloric Acid strength of 28% and should not be any greater than this percentage.
Please ensure that you use a suitable container with resistance to Hydrochloric Acid.
These containers can be purchased at pool stores.
IMPORTANT: KEEP BARE HANDS AWAY FROM POOL ACID AND ALWAYS USE CAUTION WHEN
HANDLING POOL CHEMICALS.
Installing the Acid Dosing Fittings & Attachments
• Locate the pool acid container a minimum horizontal distance of approximately 1m distance to the dosing
pump and the Chloromatic controller, to avoid possible corrosive damage from chemical vapour
• Cut a length of the clear tube (supplied), to be able to be fed into the base of the acid container
• Remove the cap from the acid container and rinse it in fresh water
• Drill a 9mm hole through the centre of cap. Feed one side of the clear tube through the top of the cap, and
secure it to the foot filter
• Push enough tube through the cap to allow the foot filter to sit at the bottom of the acid container.
Secure the other end of the clear tube to the inlet port of the peristaltic pump. (The inlet port is the left side
of the inverted “U” shaped tube on the pump indicated by an arrow pointing up on the clear plastic cover)
• Re - fit the assembled cap to the acid container at the end when all tubes and fittings are connected
through the system to avoid any syphoning of the acid from the container
• Fit all the saddle clamps to the pipe work as shown in the “Davey Peristaltic Pump AS Series”, Installation
and Operating Instructions and then attach the remaining clear tube (trim to length if required) to the
discharge port of the peristaltic pump (on right side of inverted “U” shaped tube on the pump, indicated by
arrow pointing down on clear plastic cover)
IMPORTANT: ENSURE SENSOR PROBE ALWAYS REMAINS MOIST. A NON-RETURN VALVE MAY
NEED TO BE FITTED IN THE POOL FILTRATION LINE TO STOP DRAINAGE IN THE PLUMBING. THE
SENSOR PROBE MAY BE DAMAGED BEYOND REPAIR IF LEFT TO DRY OUT. WARRANTY WILL BE
VOID IF THIS TYPE OF DAMAGE IS APPARENT.
For optimal service life of your peristaltic pump tube, it is advised not to exceed a pressure of 1 bar and
under no circumstances exceed a pressure of 1.5 bar.
In the case of an installation with redox and pH regulation, it is advised to put the two sensors side by side
and pH injection before chlorine injection to minimise the risk of scale deposition on the chlorine injection.
MAINTENANCE OF SENSORS, PUMP MODULE AND ROLLER HOLDER
The Peristaltic Pump uses a roller holder and a “squeeze” tube to pump the acid into the pool. This tube is
perishable and must be replaced periodically. We recommend replacement approximately once per year. The
tube should be visually inspected regularly for leaks or damage. It is recommended that the roller holder be
periodically inspected and replaced every 2 years.
Refer to the Davey Peristaltic Pump AS Series Installation and Operating Instructions for details.
For further information on the operation and maintenance of the Davey Peristaltic pH Pump, please refer to the
Peristaltic Pump Installation & Operating Instructions included with your ChloroMatic sanitiser.
