• If any problems are noted on the unit, turn it off using the emergency shut-off device.
• These emergency operations will generally be the result of some problem with the elec-
trical circuit, in which case you may have problems with the motors. You will therefore
need to disconnect the power to locate the fault, which may be inside the unit (short
circuit) or external to it (problems with the power supply, voltage variations, etc.).
• In the event of fire, it must be extinguished using suitable extinguishers. Extinguishers
should be appropriate for use on electrical fires.

• Preventive maintenance is a preset programme of checks that is followed regularly to
prevent equipment breakdowns.
• The supplemental Building Facility Technical Regulations are applicable at all times to
maintenance standards, except when justified otherwise for technical reasons.
• The maintenance supervisor should keep a copy of the preventive maintenance recom-
mendations given below on file, making as many copies as needed for use.
• According to the equipment’s operating needs, it is crucial to make a list of those ele-
ments that are needed to quickly resolve equipment faults. This list will serve to deter-
mine the spare parts inventory needed to be able to perform repairs quickly.
