1.2 Shipping and transporting
No matter what the means of transport employed, delivery of the
pump, even when free to purchasers or the addressee’s domicile, is
always at the purchaser’s risk. Claim for any missing materials must
be made within 10 days of arrival, while claims for defective
materials will be considered up to the 30th day following receipt.
Return of pump or other materials to us or the authorized
distributor must be agreed beforehand with the responsible
personnel. Material should be disassembled and packed with care.
All parts in contact with the chemical should be purged and rinsed
for everyone’s safety. If the pump can not be purged, fasten the
input with the output using a tube (see figure below). In the case of
non-compliance with this guideline, we reserve not to support the
materials and to return it at your expense and any damage created
by the chemical on the material will undergo a repair quote.
1.3 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. Install the pump in a dry and not floodable place and well away from sources of heat, and in any
case, at environmental temperature not exceeding 40°C. The operating minimum temperature depends of
the liquid to be pumped, bearing in mind that it must always remain in a liquid state. 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 contact our offices for further information about the characteristics
of the pump and it proper use. The manufactures can not be held responsible for damage deriving for
improper, erroneous or unreasonable use of the pump.
1.4 Risk
After unpacking the pump, make sure that it is completely sound. In case of doubt, do not use the pump
and contact qualified personnel. The packing materials (plastic bags, polystyrene, etc.) should be kept out
of the reach of children: they constitute potential sources of danger.
Before you connect the pump make sure that the voltage ratings correspond to your particular voltage
supply. You will find this value on the rating plates attached to the pump.
The electrical installation to which the pump is connected must comply with the standards and good
practice rule in force in the 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 (typical place: swimming pool),
Do not leave the equipment exposed to the atmospheric agents,
Do not allow the pump to be used by children or unskilled individuals without supervision.
The pump has to be supplied through an isolating transformer or supplied through a RDC ( max operating
current = 30mA).
In case of breakdown or improper functioning of the pump, switch off, but do not touch. Contact our
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.

In case of damage of power supply cord please ask the repair to our technical assistance or qualified and
authorized personnel.
When you decide to make no further of an installed pump, make sure to disconnect it from the power
supply.
Before carrying out any service on the item, check:
1. Disconnect the plug from the mains.
2. Relieve all the pressure from the pump head or the injection tube.
3. Drain or flush all dosing liquid from the pump head. This operation can also be done with the pump
disconnected from the plant by turning the pump upside-down for 10 seconds and without connecting
the tubing to the nipples.
In event of possible losses on the hydraulic system of the pump (breakage of the O-ring, the valves or the
hoses), the pump should immediately be brought to a stop, emptying and depressurizing the delivery hos
while taking all due the safety precautions (gloves, goggles, overalls.).
1.5 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:
• 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 fir 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 flush out and neutralize the pump head with the
proper reagent liquid.
1.6 Assembling and dismantling the pump
1.6.1 Assembly
See paragraph 3 RECOMMENDATIONS AND INSTALLATION page 8
1.6.2 Dismantlement
Proceed as follows when you dismantle the pump or before performing any operation on it :
Make sure that it is disconnected from the power supply (both polarities) by removing the
conductors from the network contact points..
See paragraph 1.2 page 5

2DESCRIPTION OF PAN DUO PH TURBOXY
The PAN DUO PH TURBOXY is characterized by its ability to measure the pH (0 to 14 pH) and some chlorine
(between 0 and 4 ppm) thanks to its placed probes in the filtration circuit which analyzes the water of your
pool.
Depending on the measured value, the PAN DUO PH TURBOXY is going to pilot dosing pumps or solenoid
valves to maintain the balance of the pH and the rate of chlorine.

3RECOMMENDATIONS AND INSTALLATION
3.1 Recommendations
If the temperature exceed 30° C, we recommend the abrasive B10 turbine use (ref : 10000019)
3.1.1 Information placard
3.1.2 Recommended chemicals
•It is recommended to use sulfuric acid, which is 100% compatible with the Santoprene tube.
•It is recommended to use chlorine diluted to 5% (maximum 10%)
3.1.3 Unrecommended chemicals
It is not recommended to use hydrochloric acid which can reduce the peristaltic tube's lifetime to a
few weeks and oxidise the pump's s metallic parts. In this case, the warranty is voided
The stabilizer rate must be less than 15 ppm in order not to disturb the reading of the redox.
The use of chlorine in hard water may clog the injection valve by the formation of a white deposit on
the part in contact with water. Please periodically check that the passage of the valve is free. In case of
blockage, the peristaltic tube may be damaged..
The TURBOXY probe ® is not compatible with the presence of salt in the water..

3.2.5 Hydraulic circuit
3.2.6 Calibration of the probe chlorinates Turboxy
Information: The probe of chlorine TURBOXY is a mechanical and strong probe, it is provided with a turbine
which detects the flow of the water and also cleans the electrode of measure in its axis. The probe
chlorinates TURBOXY require a rather long time to stabilize its measure owed to the stabilization of the
oxidation of the sensor by the chlorine in the water and its cleaning. The stabilization will be reached during
the balance between the oxidation and the cleaning by the turbine.
That is why in the first days it will certainly be necessary to re-calibrate the probe of chlorine.
1) Check that the TAC of the water is good between 150 and 250 ppm (Total alkalinity), if not to adjust it.
2) Put into service the part pH of the PAN DUO PH TURBOXY, because the calibration of the chlorine must
be realized between pH 7.2 and 7.5.
3) If you have to use of the stabilizing to reduce the destruction of the chlorine in the water by the UV of
the sun, it is necessary to stabilize manually its rate between 30 and 40 ppm (and then use some not
stabilized chlorine).
4) Maintain a rate of free chlorine in the swimming pool between 1 and 2 ppm for at least 3 hours.
5) Then, find a sample of water of the swimming pool in the place of the filtration or taken near a skimmer
in a depth from 30 to 40 cms.
6) To calibrate the chlorine part of the device as follows:
The hydraulic tube is placed in the same way on
the strainer and the pump.
1 : Slide the tube through the nut
2 : Push the tube down to the bottom of the
conical connector
3 : Hand tighten the nut onto the connector

5.1 Incorrect measure and procedure for increasing the TAC
If the displayed value on the device differs from the value obtained by another control method (drops,
strip, photometer) : check that the TAC (Total alkalinity) > 100 mg/L.
Procedure for increasing the TAC
In order to add TAC in your pool, follow the following procedure :
Stop the pH and chlorine regulators.
•Add in the pool the required amount specified on the TAC packaging. It is preferable to increase the
TAC to 250 mg/L in once.
Wait 4 hours for complete dissolution.
Turn on the pH regulator.
When the pH < 7,8 turn back on your chlorine disinfection system.
To get a stable pH value: 150 mg/L < TAC < 300 mg/L
