MIXER ADJUSTMENT INTERVALS
Using the machine in the opposite rotary direction to that specified may pose a risk to the mixer, to
objects or to people!
The mixer operating interval can be set using the Biogas plant control panel.
The optimal operating period and down-time depends on the manufacturing specifications, as well as on the
conditions of use and the fluid to be treated.
The Biogas plant control panel must only be set by authorised personnel.
As an example, the initial mixer operating period could be set as follows:
1) Standard operation Variable operating time from 2 to 5 min. and idle time 20 min. (in the event of
insufficient mixing the operating time should be increased and the idle time decreased;
2) Continuous operation.

the maximum possible level of danger.
Before using any equipment in the work place, use the pocket explosimeter to check for the
presence of dangerous levels of gas.
The equipment may only be used if the relevant CE certificates state that they can be used without
risk in explosive atmospheres; all equipment must bear a symbol
Necessary measures must be adopted to ensure that the equipment has been designed, built, assembled and
kept efficiently, and used in such a way as to reduce the risk of explosion, as well as the scope of any potential
explosion, to a minimum.
