Nilfisk-Advance America GB 1133 - Manual (Page 9)

8 Initial operation
Please read these notes of safety before initial operating.
The application scope of the machine is marked on the rating-plate.
Industrial vacuum cleaners are exclusively designed for removing settled dusts.
Extractors are designed for removing dust at that very place where it is produced.
Having removed the system from packaging, check it for completeness and
transportation damage. In case of damage or missing parts please contact Nilfisk-
Advance immediately. Before connecting the vacuum cleaner to the mains supply,
check that the voltage of the machine specified on the rating-plate corresponds with
the mains voltage.
Switch the motor on to control its direction of rotation.
When it is wrong, a red lamp at the switch housing flashes up.
Extractors: an arrow on the motor housing shows the right direction of rotation.
Working for a long time with the wrong direction of rotation heatens the
vacuum cleaner’s surface up to over 80°C.
When the direction of rotation is wrong two phases in the mains supply (not within the
machine) need to be exchanged. All electrical sockets of the workplace should have
the same phase sequence in order to operate the system in all areas of the
workplace.
Systems with antistatic design (B1)
These machines are not suitable for removing explosive materials, dusts with an
extremely low minimum ignition energy of less than 1 mJ and inflammable liquids.
Do not use others than conductible original Nilfisk-Advance accessories.
Use couplers that only allow connecting and disconnecting the system in voltage-free
condition.
Antistatic systems must be equipped with a protective circuit breaker or a blowout
fuse 16 A (delayed-action fuse).
The use of coupling devices and adapters is not allowed.
The system is ready for use when all equipment has been connected.
