The main information for the safety of the product and user is provided in the "Safety Information" leaflet supplied with this manual.
1.4 Training of installation and maintenance staff
The staff assigned to install and maintain the product must be trained in the inevitable residual risks related to electrical equipment operating in
contact with biological liquids.
They must also be capable of reading and understanding the contents of the technical documentation supplied with the product, especially the
electrical wiring diagrams.
1.5 Residual risks
The product is designed and built to ensure safe, reliable use.
However, since it is intended for use with liquids that constitute a health hazard, the installation and maintenance staff must take great care and
always wear regulation personal protection equipment.
During all work on the product, users must take care not to drop the pump and must not underestimate the risks of burns, electrocution, drowning
and suffocation or poisoning due to the inhalation of toxic gases.
To reduce the risks associated with lightning, the user is required to install any necessary and adequate lightning protection mea-
sures.
Any intervention which modifies the pump components can create a DANGER of EXPLOSION.
The pumps MUST be used ONLY in areas compatible with the characteristics recorded on the label.
During handling, installation or disinstallation operations the pump must be disconnected from the power supply panel.
1.6 Product description / Intended use
Zenit UNIQA is a range of submersible electric pumps with energy-saving motor.
These products are intended for use in residential, industrial and municipal sewage treatment plants and lifting stations.
They are designed to lift and pump slurries, faecal material, clean water, waste water or water soiled with solid or fibrous materials.
They may not be used with liquids for human consumption or in potentially explosive atmospheres (except for models with explosion-proof certi-
fication).
ATEX electric pumps, identifiable by the -EX acronym, are certified according to the antideflagrant protection mode recorded on the plate
for the operation within shafts, tanks and, in the version including cooling jacket, in drying chambers where explosive gas/dust is present
or in any area classified as Zone 1 or 21; the user is required to define a suitable inspection programme in order to avoid the layer
of dust on the surface of the electric pump from exceeding 50 mm.
Usage: drainage, evacuation and/or removal of waste from sewers and septic tanks in areas with the PRESENCE OF GAS AND EXPLO-
SIVE DUST (-EX); removal of liquids containing solid and filamentous particles; drainage water, purification water and washing water from
civil and industrial processes in atmospheres containing group II A and/or B gas (usually hydrocarbon gas) and/or atmospheres containing
a mix of combustible dusts.
!
The -EX approval lapses following interventions or repair work carried out by unauthorised workshops or staff. Ac-
warning
cordingly, the electric pump can no longer be used in areas with an explosion danger.
The -EX plate will have to be removed.
