Aeration; Solution Temperature - Walter Surface Technologies BIO-CIRCLE COMPACT-S 350 Manuel De L'utilisateur

Aeration

The air pump located inside the RMU (H) should always be heard running
and air bubbles should be visible at the surface of the liquid, close to the
pump support tube, when the machine is plugged in.
This built-in aeration feature is vital to the performance of the bioremediation
process.

Solution Temperature

The temperature control is factory set to maintain the solution at
41º C ± 1º (106°F ±2°). At this temperature the bioremediation process is
most efficient, cleaning is faster and operator comfort is optimized.
