warning!
Any modifications made to the product without the manufacturer's authorisation may cause hazards and lead to a deterio-

The responsibility of repair, overhaul or maintenance to the pump in -Ex versions lies with the user of the product: make sure
that any interventions is carried out by an Ex-Certified Service Centre (according with international and/or local standards and
rules) or by a Zenit Service Centre.
1.8 Storage
During storage, the electric pump must be kept in a suitable place, out of the reach of children or those with diminished responsibility,
suitably secured against falling and protected from damp, vibrations, dust and extreme temperatures (below -20°C/-4°F and above
+60°C/140°F).
If the pump should freeze, do not use flames to remove the ice; immerse it in the liquid in which it is to be installed until it thaws out.
warning!
Turn the impeller by hand occasionally (at least every 2 months) through the outlet or intake, to prevent the mechanical
seals from sticking together.

• Liquid/Ambient temperature: 0 ÷ 40°C
• pH value: 6 ÷ 14
• Duty service: S1 operation (continuous operation), the pump must always operate fully submerged
• Starts per hour mode: maximum 20 for motor with rated power P2 up to 10 kW, 15 for P2 over 10 kW
The -Ex version pump can be used with a frequency converter (inverter) with the compulsory condition that the thermal protec-
