Periodic Maintenance - S&P HIT 1.250 Notice D'installation Et D'utilisation Succincte

8 MAINTENANCE STANDARDS
The S&P HIT / HIB air extractors have been designed and manufactured for
long useful life even under the most severe conditions. However, note that the
equipment has moving parts and, as such, requires periodical inspections.
Therefore, it is recommended to implement a preventative maintenance
programme, which should be carried out by competent and specialised
personnel.
Daily inspections should be performed to prevent breakdowns caused by
harmful work environment related effects, such as temperature, humidity, dust,
dirt, vibrations and other factors.
8.1 SAFETY WARNINGS DURING MAINTENANCE
 Maintenance of the extractor should be carried out only by personnel trained in
the safety standards and recommendations set forth in this Manual. Before
performing maintenance, disconnect from the electrical supply by switching off
the master switch.
 When performing any operation on the machine, all personnel must be notified.
 When accessing the machine for maintenance, place a warning sign over the
power supply switch to prevent another operator from accidentally switching the
machine on.
 During the machine maintenance and inspection phases, there are risks of the
fan catching and cutting clothing, extremities, of hair being caught and also risks
to other parts of the body.
 During these phases, Use the PPE indicated in section 2.1, especially the
safety clothing and the gloves; tie back long hair and do not wear rings,
bracelets or necklaces.
