6.2 - Daily use
- If hoses are used, make sure the ends are properly connected to the tanks. Firmly hold the end of the discharge pipe to prevent
accidental spillage.
- Before starting the pump, make sure the discharge valve or the nozzle is closed.
- When you are ready, switch the pump on. The pump can remain in bypass (internal circulation if the discharge is closed) only for
brief periods.
- With the pump on and in bypass, open the discharge valve or nozzle holding it firmly.
- When you have finished dispensing, close the valve or nozzle and switch the pump off.
6.3 - Noise level
Under normal operating conditions the noise emitted by all models does not exceed 80 dB at a distance of 1 metre
from the electric pump.
CAUTION! Operation of the pump with discharge closed is allowed only for brief periods (max 1-2
minutes).
Make sure the pump is switched off after use.
If there is a power failure:
1. Close the discharge valve or nozzle
2. Put the end of the discharge pipe into its housing on the tank
3. Switch the pump OFF
When the power has returned, restart the pump as described at the beginning of the section.
6.4 - Compatibility in an electromagnetic environment
The machine is designed to operate correctly in an industrial electromagnetic environment, and staying within the Emission
and Immunity limits laid down in the following Harmonised Standards:
IEC EN 61000-6-2
Electromagnetic compatibility (EMC) - Generic standards – Immunity for industrial environments
IEC EN 61000-6-4
Electromagnetic compatibility (EMC) - Generic standards – Emission standard for industrial
environments
