URTHER HINTS AND WARNINGS
Please read the warning notices given in this section very carefully, because they
provide important information regarding safety in installation, use and mainte-
nance of the pump.
• Keep this manual in a safe place, so that it will always be available for further
consultation.
• After unpacking the pump, make sure it is completely sound. In case of doubt,
do not use the pump and contact qualified personnel. The packing materials
(especially bags made of plastics, 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, etc., corre-
spond to your particular power supply. You will find these values on the rating
plate attached to the pump.
• The pump should be used only for the purpose for which it has been expressly
designed, namely the dosing of liquid additives. Any different use is to be con-
sidered improper and therefore dangerous. The makers cannot be held responsi-
ble for damage deriving from improper, erroneous or unreasonable use of the
pump.
• Use of electrical equipment always implies observance of some basic rules: In
particular:
1 - do not touch the equipment with wet or damp hands or feet;
2 - do not operate the pump with bare feet (Example: swimming pool equipment);
3 - do not leave the equipment exposed to the action of the atmospheric agents;
4 - do not allow the pump to be used without supervision by children or incompe-
tent people;
•
Before carrying out any maintenance or cleaning operation, disconnect the
pump from the power supply by means of the circuit breaker.
• In case of breakdown or improper functioning of the pump, switch it 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 for use.
•
When you decide to make no further use of an installed pump, make sure to dis-
connect it from the power supply.
• 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.
•
The pump complies with EEC directives No.89/336 regarding "electromagnetic
compatibility" and No.73/23 regarding "low voltages", as also the subsequent
modification No.93/68.
• Maximum environmental operating temperature: 40°C.
Before carrying out any service on the item, check:
1. Disconnect the pins from the mains or by means of a onnipolar switch with 3
mm minimum distance between the contacts. (item 6.0/b)
2. Relieve all the pressure from the pump head and 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 15 to 30 seconds and without connecting the tubing to the nipples: if this
operation is not possible, dismount and remount the pump head using the four
mounting screws.
