In case of failure and/or malfunctioning of the pump, switch it off and do not attempt to repair it. For any repairs,
please contact our after sales service centres and request the use of original spare parts. Failure to comply with these
conditions may compromise the correct operation of the pump.
In the event of damage to the power cable of the pump, request a replacement from our service centres or qualified
personnel to avoid risks to the people who use it.
This equipment is not explosion proof. DO NOT install and DO NOT use in an explosive or potentially explosive
environment.
Dispensing harmful and/or toxic liquids
The following rules, along with the instructions in this booklet, must be kept in mind to avoid personal harm or property
damage due to contact with harmful liquids or the intake of toxic fumes:
Intended use of the pump
The pump must only be used for the purpose for which it was specifically built, i.e. for dispensing liquids. Any other use
must be considered dangerous. Use of the pump for applications not foreseen in the design stage is prohibited. For further
explanations, the customer may contact our offices for information on the type of pump in their possession and its correct use.
The manufacturer cannot be held liable for any damage caused by improper, incorrect or irrational use.
Shipping to the factory for repairs and/or maintenance
The material to be shipped to the factory for maintenance must be disassembled and packaged carefully; all parts in
contact with the chemical product must be emptied and rinsed to ensure the safety of operators during transport and handling
of the material in the laboratory. In case of failure to comply with the instructions provided, we reserve the right not to collect
the material and to return it at your expense; any damage caused to the material by the chemical shall be included in the repair
estimate.
Assembly and Disassembly
All metering pumps manufactured by Etatron D.S. are normally supplied fully assembled. For further explanations, please
consult the attachment at the end of this manual where exploded drawings of the pumps and all parts with relative nomenclature
are displayed in order to have a complete picture of the pump. These drawings are anyhow required to recognise the
malfunctioning or defective parts. Other drawings regarding the hydraulic parts (pump head and valves) are reported for the
same purposes, also in the attachment.
To disassemble the pump or before carrying out any operations on it, you must:
Particular attention is required for this last point, therefore it is advisable to consult the drawings in Annex 1 and the
"Warnings and Risks" paragraph before starting any operation.
22 ENGLISH
Always wear protective clothing, including gloves and safety goggles, operating as recommended by the
manufacturer of the liquid (additive) to be used (risk of potential explosions, burns, fire, injury or personal
damage).
Check that the hydraulic part of the pump is not damaged or broken and use the pump only in perfect condition.
Use tubes suited to the liquid and the operating conditions of the plant, inserting them, if necessary, into
protective PVC pipes.
Before disabling the metering pump, the system must be depressurised and the hydraulic part must be
neutralised via the appropriate reagent.
When connecting a metering pump to the public water mains or to your own water source, it is required to comply
with the regulations in force regarding protection or specifically dictated by the mains manager. In both cases,
always prepare safety devices that prevent flows from returning to the source, such as check valves, etc.
CAUTION: Protect the pump and chemicals from weathering (frost, rain, sun, etc.).
It is recommended to install the pump in areas where liquid product (additive) leaks cannot cause personal injury
or material damage.
Make sure it is switched off electrically (both polarities), disconnecting the conductors from contact points of the
mains by opening of an omnipolar switch with minimum 3 mm distance between the contacts (Fig.6).
Appropriately eliminate any pressure in the pump body and in the delivery tube, paying the utmost attention.
Eliminate all liquid present from the pump body, proceed by disassembling and reassembling the pump body,
unscrewing and tightening the four fixing screws (tightening torque 180-200 N*cm).
