Maintenance

FILTERS
Filters must be properly maintained in order to ensure proper air cleaning efficiency and to maintain design
airflow. Acoustic output may also be adversely affected by dirty filter.
The length of time between cleaning of filters is dependent upon the air condition. A three month cycle is normal,
however more frequent maintenance may be required in some cases.There is one air filter fitted to the equipment
in the inlet air path, upstream of the heat exchange coil. The filter may be slid out to either side of the unit. Alterna-
tively, the crosshead screws which fix the filter retaining angle to the equipment body may be loosened to provide
sufficient clearance for the filters to be manoeuvred out of their retaining channels. Where the equipment includes
for the filter to be fitted within a separate in-board filter section,remove the screws securing the access panel and
remove the filter. Initially, cleaning can be performed by gently tapping and removing loose dust with an air line or
vacuum cleaner.
Once removed, washable filters may be fully immersed in warm water with a mild detergent solution. Agitate the
water until all contaminants have been removed. The filter should then be rinsed in clear water, allowed to drain
and air dried before replacement. In the event of heavy soiling or damage to the filter media or wire support frame,
the entire filter should be changed. When refitting new filters into the equipment, it is important to ensure these are
fitted correctly in respect of airflow. The correct orientation is obtained when the wire frame is positioned towards
the heat exchanger, and the filter media completely covers the wire frame
