Maintenance
Warning! Isolate from the electrical supply
before performing any work on the unit.
The internal air filter is removable for servicing.
To gain access to the filter unlock and lower the
front access panel, remove the 2 screws from the
filter enclosure panel and lift out. Carefully lift
out and remove filter. The filter should be gently
tapped to remove any accumulated dust and
vacuumed if necessary (approx. every 6 months).
We recommend replacing the filters approx. every
2 years depending on environmental conditions.
The coil fins are delicate so take care and only use
a soft brush or vacuum cleaner to remove any
dust that may have accumulated.
