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

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
• The appliance must be placed in a place that can not be flooded.
• The appliance must be connected electrically via a means of disconnection to the supply network, the opening
of the contacts of all the poles ensuring a complete break under the conditions of overvoltage category III.
