important information regarding safety in installation, maintenance and use
of the pH pump.
• Keep this manual in a safe place, so that it will always be available for
further consultation
• The device complies with N° 89/336/CEE “electromagnetic
compatibility” and N°73/23/CEE “ low voltage ” and also the
subsequent modication N° 93/68/CEE
Note: This pump has been constructed in accordance with best practice.
Product life, electrical and mechanical reliability will be enhanced if it
is correctly used and regularly maintained.
WARNING Any intervention or repair to the internal parts of the pump must
be carried out by qualied and authorised personnel. The manufacturers
decline all responsibility for the consequences of failure to respect this rule.
1.1 Proper use of the Pump
The pump should be used only for the purpose for which it has been
expressly designed namely the dosing of liquids. Any different use is to
be considered dangerous. The pump should not therefore be used for
applications that were not allowed for in its design. In case of doubt, please
refer to the details listed within this document, or contact your point of
purchase or Davey Water Products for further information. The manufacturer
of this product will not be liable for damage deriving from improper,
erroneous or unreasonable use of the pump.
1.2 Risks
• After unpacking the pump, make sure that it is completely sound. In
case of doubt, do not use the pump and contact Davey
•The packing materials (plastic bags, polystyrene, etc.) should be kept
out of the reach of children: As they may constitute a potential source of
danger
• Before you connect the pump make sure that the voltage ratings
correspond to your particular voltage supply. You will nd this value on
the rating plates attached to the pump
• The electrical installation to which the pump is connected must
comply with the local standards enforced in the state or country under
consideration
Use of electrical equipment always implies observance of some basic rules.
In particular:
- Do not touch with wet or damp hands or feet.
- Do not operate the pump with bare feet (example: swimming pool
equipment)
Never connect your pH pump direct to mains power. Always
connect it to the chlorinator power supply so it operates during the
preset ltration time cycles.

4
- Do not leave the equipment exposed to atmospheric agents
- Do not allow the pump to be used by children or unskilled individuals
without supervision
• In case of breakdown or improper functioning of the pump, switch it
off, but do not touch. Contact Davey for technical assistance for any
necessary repairs and insist on the use of original spares. Failure to
respect this condition could render the pump unsafe to use
• When the Davey AS Series pump is not in use for a substantial period
of time, or use is to be discontinued, disconnect the unit from any power
supply
Before carrying out any service on the pump:
1) Disconnect the mains power from the unit and
2) Relieve all the pressure from the pump head or the injection tube
In the event of possible losses on the hydraulic system of the pump
(breakage of the O-ring, the valves or the hoses), stop the pump
immediately and contact Davey.
1.3 Toxic and/or Dangerous Liquid Dosage
To avoid risk from contact with hazardous liquids or toxic fumes, always
adhere to the notes in this instruction manual and wear protective clothing
(gloves, goggles & overalls).
• Follow the instructions of the dosing liquid manufacturer
• Check the hydraulic part of the pump and use it only if it is in perfect
condition
• Use only the correct materials for the tubing, valves and seals to suit the
liquid to be dosed: where possible shield the tubing with PVC conduit
• Before disconnecting the metering pump, make sure to ush out and
neutralise the pump head with the proper reagent liquid
1.4 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.

2.Pump Description
The Davey Peristaltic pump is characterised by its ability to measure pH
value (between 0 and 14) with its probe placed on the ltration system
that analyses the pool water.
Depending of the measured value, the pump will inject the required
amount of product needed to maintain the balance of the pool water.

3.Installation Recommendations
3.1 Recommendations
• Install the pump in a dry place and well away from sources of heat
and in environments not exceeding 45°C. The operating minimum
temperature depends on the liquid to be pumped, bearing in mind that it
must always remain in a liquid state
• Carefully observe any standards in force in your state, territory or
country, as to electrical installation regulations and requirements
• The Davey AS Series pump will be in operation only when your ltration
pump is running
WARNING
• It is important to keep a minimum distance of 200mm
between the probe “C“ and the injection valve “E”
• The injection valve “E” must be placed last in the pipework
hydraulic installation
• In the case of an installation with redox and pH regulation,
it is advised to put the two sensors side by side and the
pH injection before chlorine injection to minimise the risk of
scale deposition on the chlorine injection
• 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
• The pH probe must be located before any other device
such as a heater or an electrolyser
Please refer to the enclosed Davey ChloroMatic or Sanitiser
Installation & Operating Instructions for the “Injection Valve”
and “pH probe” location and positioning.

5.Commissioning and Operation
5.1 Calibration Procedure
This operation is used to set the sensor response reading of the pH and
peristaltic pump.
Some important points
• To ensure the probe signal remains as accurate as possible, please
follow the procedure as listed below during the commissioning of the
pool and every 3-4 weeks thereafter, or as required.
• The procedure is renewed in case of abnormal consumption of
chemicals.
1) Remove the
protective cap
of the probe and
keep it for reuse
at the time of
winterising
2) Rinse the
probe in tap
water for at least
20 minutes
Steps:
Before carrying out the calibration of the probe,
remember to:
• Stop the ltration pump
• Close the isolation valves, if tted
• Remove the probe from the probe holder
• Put the shutter washer (g. 12) in to close off
the hole in the probe holder
• Open the isolation valves, if tted
• Turn on the ltration pump and check that the
ON/OFF switch (I/O) of the AS Series
pump is switched to “I”
• Carry out the calibration of the probe and
repeat the previous actions to put the probe
back in place. As described in 3.2.4

5.3 Operating Principle
The Davey Peristaltic pump adjusts its dosage in proportion to the
demand. It will dose less if the displayed measure is near the set point. In
normal operation, the AS Series pump will increase its ‘non operational’
time period proportional to the required dosage demand. That is why the
device often has the pump off. This is normal.
Adjust the pH slowly to preserve the natural quality of your water.
After 30 minutes without pressing the keys, the backlight turns off to save
energy. A short press on SET or CAL turns it on again.

6.2 Maintenance of the Peristaltic Tube 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.
6.3 Maintenance of the probe
Over time, in addition to the normal wear of the probe, according to use
and water quality more or less calcareous, measurement will deteriorate.
A thin layer of limestone with other elements present in the pool water will
deposit on the sensing element of the probe. To overcome this problem,
it is advisable to use the cleaning solution for electrode/pH probe and
redox AYACSOLNET01 and follow the procedure on the suppliers’ bottle.
6.4 Controller Wintering
Only in areas where subzero temperatures are experienced
• During winterising, you must protect the peristaltic tube
• It is advisable to remove the peristaltic tube and ush it with fresh
water. Once complete ensure the tube is completely dry and re-install
as shown on page 13, Fig 13, 5.1
6.5 Probe Wintering
• During winterising, the probe must be removed from of the installation
and pipe work
• The protection cap as shown on page 11, must be lled with fresh
water a 1/3 of the way up
• Place the probe into the protection cap and water and store in a safe
place until after the winter period is over. (Re-install as shown on page
10, gure 9)

7. Trouble Shooting
Error Reasons How to solve it
CAL Err
If this error is displayed
during the calibration
phase and cycle it is as
a result of:
1). Your pH probe is not
working properly
2). Your buffer solution
is polluted
3.) You have water/
oxidisation in the
probe connector
1). Change the probe
2). Change the buffer
solution
3). Change over the
probe
Alarm Alr Err
If the pH is lower than
pH 5 or above pH 9, this
alarm will be displayed
and dosing will be
stopped.
Adjust your water
parameter manually so
that it comes back to the
required value of these
parameters:
- Total alkalinity
- TH (hardness)
- pH
The dosing pump will
restart as soon as the
pH reading
If trouble persists, please contact Davey or your nearest Davey
Dealer for assistance.
