1.2 Shipping and transporting
L’expédition 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 device must be supplied through a circuit with a residual current differential device (RCD) rated differential
operating current not exceeding 30 mA
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, to avoid any hazard.
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, etc.).
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 9
1.6.2 Dismantlement
Proceed as follows when you dismantle the pump or before performing any operation on it :
•Disconnect the plug from the mains.
•See paragraph 1.2 Shipping and transporting page 5

2DOS-ECO DESCRIPTION
The DOS-ECO is characterized by its ability to measure the pH (0 to 14 pH) with its probe placed in the filtration
circuit which analyzes the water of your pool.
Depending on the measured value, the DUO will inject the amount of product needed to maintain the water balance
of the pool thanks to its dosing pump.
The DUO operates as dosing acid (pH-) or basic (pH+) depending on its configuration.
2.1 Parts description
The complete list of accessories delivered with the equipment is given below. All the parts will be necessary for the
correct operation of your unit.

3RECOMMENDATIONS AND INSTALLATION
3.1 Recommandations
1.1.1 Nameplate
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.

STEP 7 : Electrical connection
Filtration sensing cable and power cable
1° Plug the cable i (without plug) for filtration detection into the electrical box D on your pool:
- Either on the terminals of an auxiliary contact to the relay of the filtration pump
- Either on terminals A1 and A2 in parallel with the coil of the filter pump relay
The voltage to be applied to this cable is 230V~. This means that the unit will only be supplied with power when
the filter pump is switched on.
2° Connect the power cable with its domestic electrical plug. It is preferable that the 230 Vac power supply come
from the electrical box D of your pool just after the main switch.
STEP 8 : Connect the pH and Rx probes to the corresponding plug of the instrument.
Insert the plug into the bayonet socket Turn the plug ¼ to close the connection.
