1.3 INDIVIDUAL PROTECTIVE DEVICES (IPD) TO BE USED

When handling the product, especially if already installed, always wear the following items of protective clothing: Accident-
prevention shoes, safety goggles, accident-prevention gloves and a leather apron or similar form of protection.
Every time maintenance or repair operations are performed on installed electric pumps, particularly those which are immersed in
dangerous liquids or septic tanks, all parts must be thoroughly cleaned and washed with water or specific products.

2 . DEVICE IDENTIFICATION

A metal identification plate stating all the product specifications is applied to the electric pump. Refer to the data on this plate when
seeking information or clarifications.

2.1 ATEX MARKING (potentially explosive environment)

0575
According to EN 60079-0 the plate coding summarises the following:
The symbol shown is in conformity with Annex X of Directive 94/9/CE and identifies that the product meets the
essential health and safety requirements laid down by that directive.
0575 identification number of the organisation undertaking the production control
