MAINTENANCE
Make sure the mains supply of the unit is disconnected before performing any maintenance. The maintenance must be carried out by a qualified
technician and in accordance with local rules and regulations.
Filters of the unit require changing according to the filter change period. When the filters are dirty less air will be supplied by the unit and impact the
effectiveness of the unit. In areas of high pollution e.g. beside main roads more regular replacement may be required. Filters can be supplied by Elta Fans.
Filters should be checked annually or if a drop in ventilation rates are noticed.
The filter should be checked regularly to determine if it needs cleaning or replacement. External environmental conditions will determine how often
the filter will need to be cleaned or replaced. Reduced airflow, perhaps accompanied by an increase in noise level, may provide indication that the
filter needs to be cleaned or replaced. The filter should be inspected and
cleaned or replaced as required at intervals not exceeding 2 years
and always replaced at intervals not exceeding 5 years.
