Installation
General
•Installation must only be performed by an authorized Technician/Electrician who has carefully
read the installation guide. This is to prevent electric shock or damage to the machine and a
trouble free installation.
•To ensure correct performance, the air cleaner should be properly installed on the machine
tool. The installation area must be stable and vibration-resistant. If the machine is not capable
of supporting the weight of the AOF, use a stand or mount to a wall.
•To maintain efficiency, maintain high bend radius in hoses.
•The electric wiring must comply with electrical standards and should be completed by a
qualified and competent Electrician or Technician.
•Our AOF units come pre-wired for 220V 3 phase supply (220/3/50) and may also be
configured for 415V 3 phase (415/3/50). For further electrical information, refer to the
following guidance in this manual.
•When installing the unit, motor / overload protection must be provided. A suitably sized DOL
starter or motor protection circuit breaker should be used.
•Do not change the power wire length or use extension wire.
