● Switch off the machine and secure it against restarting. This
also applies to auxiliary circuits (e.g. standstill heating).
● Check there is no voltage!
● Establish a safe protective earth connection before starting
work!
● Deviations from the rated values for voltage, frequency,
curve shape, symmetry of the feeding network increases the
heating and influence the electromagnetic compatibility.
DANGER!
In case the side channel blower conveyed gas that was
contaminated with foreign materials which are dangerous to
health, harmful material can reside in pores, gaps and internal
spaces of the side channel blower.
Danger to health during dismantling of the side channel
