GETTING THE MOST FROM YOUR ELECTROSTATIC AIR CLEANER
The air cleaner keeps you informed of its running status. Lights on the Display Panel provide information.
The YELLOW ‘ON’ light indicates that the air cleaner
is functioning correctly. An occasional snapping
sound from the air cleaner (sometimes called arcing)
confirms the air cleaner is running normally. Press
the ‘TEST’ button to hear the snapping sound.
The CHECK LED will light when the TEST button is
pressed.
If the RED ‘CHECK’ light is on permanently; this is an
indication that the air cleaner has developed a fault.
Usually it means a fault with the internal power supply
but there are some checks you can do before calling
your service dealer. (See later section on Service
Checks).
Some models are equipped with a ‘WASH’ light. This
light indicates that the cleaning cell is loaded with dirt
and that its efficiency has dropped below acceptable
working levels. The cell must be washed to return
the air cleaner to its original efficiency. If this light is
on but the cell is not dirty, turn to the section on
Service Checks before calling your service dealer.
An activated carbon filter can be installed to help control odours. This filter is fitted inside the access cover
next to the prefilter. F57A models use two carbon filters one on either side of the prefilter, whilst F57B models have
a single carbon filter which sits to the left hand side of the prefilter. Carbon filters should be changed approximately
every 6 months depending on usage. They are obtained from your installer or service dealer.
Instead of switching the air cleaner off when not in use, why not leave it to run on the LO setting? This will ensure
maximum air cleaning benefit is achieved.
