Model 3400:
The vacuum head (1) is equipped with a floater which stops the air flow when
the water has reached its maximum level in the vacuum drum (5). The appliance looses
suction power and there is a change in the noise of the motor.
Model 3400S:
Also on this model, equipped with a separator, there is a loss in suction power
and a change in the noise of the motor when the water has reached its maximum level in the
vacuum drum (5).
(i) Turn off the vacuum power switch (2) and unplug the power cord (3). Lift the vacuum head
(1) from the vacuum drum (5) by releasing the latches (6) and empty the drum making sure to
have detached the vacuum hose (24) before. If necessary rince the drum and refill it as
described in step (b) of this section.
(j) When the red "low water" indicator (14) lights up, turn off the main power switch (13) of the
boiler and unplug the power cord (23) from the main current. Wait until the residual pressure
in the boiler decreases and permits you to remove the boiler cap (17). At this point you can
proceed with refilling the boiler as described in step (a) of this section.
Warning:
the boiler
cap, for safety purposes, does not permit removal with pressure inside the boiler.

clean water to rince internally the flexible hose and the vacuum tubes. Extract the vacuum
drum (5) and after having it emptied and rinced, let it dry in a well-aired place.
