Removing and installing the filter:
a. NOTE that the unit comes with the filter sealed in a plastic bag. This bag must be
removed from the filter (and then properly disposed of ) before operating the unit.
b. To remove the filter, lay the unit on its rear as shown in the above drawing. The
filter is removed from the base of the unit.
c. The filter has 2 handles, where one of the handles is also a latch. Push on the
latch and pull out the filter using both handles.
d. To install the filter, slide the fi lter into the base of the unit, as shown in the above
drawing, until the latch catches in the base fitting.
The Washable Pleated Filter:
a. The Washable Pleated Filter is recognised by the pleated fi lter material which is
exposed on both sides of the plastic filter frame.
b. The Washable Pleated Filter has the advantage that the accumulated dirt can be
washed out from the filter and then the filter can be reused.
c. When the Washable Pleated Filter is new it is a light cream colour. When the
filter material has turned dark grey or the air flow out of the unit has substantially
dropped, then it’s time to wash the fi lter.
To wash the fi lter:
a. Remove the filter from the unit as described above.
b. Rinse the dirt out of the filter pleats from both directions using clean flowing
water preferably from a spray nozzle.
c. NOTE that the fi lter material will regain much of its filtering performance, but its
colour will remain grey.
d. Allow the filter to completely dry before using.
e. Install the filter in the unit as described above.
