TANK EMPTYING

The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the fl oor is
not dried.

machine movement), to resume the operation: turn off the vacuum system by pressing the switch (52), then
open the cover (18) and check that the fl oat inside the grid (33) has gone down to the water level. Then close the
cover (18) and turn on the vacuum system by pressing the switch (52).
