Read the manual carefully before starting to install the equipment and keep it in good condition near the equipment throughout its lifetime.
1.1. Personal safety
• This device may be used by children at least eight years old and by persons with impaired physical, sensory or mental capacities, or with no
experience or previous knowledge, on the condition that they are correctly supervised or that they have received instructions on the safe operation
of the device and if the potential risks have been understood.
• Children should not be permitted to play with the device. User cleaning and servicing tasks should not be done by children without suitable
supervision.
1.2. Precautions for installation and maintenance
• Installing a VEX unit can be risky due to live components or moving mechanical parts. This equipment must be installed, commissioned and repaired
by qualified, trained personnel, in compliance with the standards in force and best practices.
• Any servicing or maintenance operation that necessitates opening the access doors or removing components from the unit must be carried out by
a qualified professional without fail.
• Electrical connections must be made by a qualified professional according to the rules of French standard NF C 15-100.
• In particular, a circuit breaker device with an opening distance of at least 3 mm on each pole, as well as a protective relay with a suitable current rating,
must be installed in the fixed ducts (circuit breaker). The copper conductor sections are defined in Sections 2.9.3 and 2.9.4 of the installation manual.
• The product's power supplies must be switched off before any maintenance or cleaning operation.
• Make sure that the unit cannot start running accidentally.
• If one of the power supply cords is damaged, it must be replaced by the professional who installed the product or similarly qualified persons to avoid
danger.
• Overheating of the motor will reduce its modulation in linear fashion. When it exceeds its maximum permitted inside temperature, the controller stops
the motor and restarts automatically after cooling. Should the motor fail (signal fault in the motor's built-in circuit, phase breakdown, motor blocked,
short circuit at the earth or internal short circuit, intermediate and network under-voltage or over-voltage, peak current fault), an alarm triggers the
stopping of the unit. Switch off the power supply (circuit breaker on electrical switchboard), check that nothing is hindering the operation of the unit
(for example, blocking, rubbing, fouling of the wheel, abnormal noise, etc.).
• If the problem persists, contact your installer or vendor.
• Only use genuine replacement parts supplied by the manufacturer.
• For units fitted with an electrical heating coil: where there are multiple failures of the electrical coil control and if the air supply compartment overheats
(ambient temperature > 80°C), a thermostat with automatic reset will trigger the stopping of the electrical coil. The electrical coil is fitted, moreover,
with a thermostat with manual reset activating at 120°C located in a thimble, between the resistors.
• The equipment must not be modified in any way to avoid invalidating the warranty.
• Service the equipment regularly to ensure its smooth operation.
