INSTALLER AND ELECTRICAL CONTRACTOR RESPONSIBILITY
Vent-Axia Ltd, as suppliers of the equipment cannot be responsible for the final
installation and electrical connection of the product on site. We have made reasonable
effort to offer guidance and assistance but the installer and electrical contractor on site
have a responsibility for ensuring the equipment is safely and securely installed and
electrically/mechanically safe in accordance with statutory requirements.
The fans are supplied as a component to be incorporated into a ventilation system. The
final complete system installation that includes the fans MUST meet the requirements
of:-
Low voltage Directive 72/23/CEE
Machinery Directive 89/392/CE
Electromagnetic Compatibility Directive 89/336/CE
If the fan is installed in an area where there is possible danger to safety or health then
guards MUST be fitted.
Guards suitable for many applications are available from Vent-Axia Ltd.
Please remember that fans need maintenance, cleaning and inspection. Allow for
reasonable access for these operations to be carried out safely.
If in doubt, please ask.
ROUTINE INSPECTION/MAINTENANCE
THIS MUST BE UNDERTAKEN BY A COMPETENT PERSON.
ISOLATE UNIT FROM ELECTRICAL SUPPLY AND ENSURE THAT IT CANNOT BE
ACCIDENTALLY TURNED BACK ON.
1.
We recommend that after three months the fan should be inspected and cleaned
to remove deposits on the impeller or motor. Thereafter, it should be checked and
cleaned periodically as experience dictates, or at least twice a year.
2.
If a build-up of dirt/deposits is evident then this should be carefully cleaned off.
Please take care not to damage the fan or affect the balance of the impeller motor
assembly (balance weights may be fitted to the impeller).
3.
The fan motors are fitted with ‘sealed for life’ bearings and should not require
maintenance under normal circumstances.
