1. GENERALDESCRIPTION
1.1 The Johnson & Starley Cleanflow electronic air cleaner is designed to replace the passive air filters normally supplied with
air heaters and to provide an inexpensive means of efficiently cleaning the air of dust, pollen and even smoke. The elec-
tronic air cleaner consists of two special glass fibre pads mounted inside a retaining frame, and a central screen between the
pads. Dust and other particles passing near to the fibres are attracted to them and retained by an electrostatic charge. The
particles themselves, however, are not charged so any which escape the filter will not be attracted to walls, curtains or
furniture.
1.2 Since the power consumption of the cleaner is low (less than 1 watt), it has been arranged to operate as long as there is an
electrical supply to the air heater. This means that it can be used with the SummerAir Circulation facility provided on the
heater.
2. MAINTENANCE
2.1 The only maintenance required is to remove the Cleaner element approximately every fortnight, inspect it for build up of dust
and deposits, if necessary, remove deposits from the screens and periodically replace the Cleaner pads.
Note: If the cleaner pads are allowed to collect too much dust, operation of theAir Cleaner and air heater may become
ineffective.
2.2 Tochange theCleanerpads:
2.2.1 Switch OFF the electrical supply to the unit.
2.2.2 Cleanflow Petite only: Disconnect the jack plug on the top right of the Cleaner element.
2.2.3 All applications: Gently withdraw the element and vacuum off any accumulated dust from the outside.
2.2.4 Undo the two latches and open the Cleaner element.
2.2.5 Before removing the dirty pads, note that the white electrode and the thin spring like wire (discharge switch) are on
topof one of the pads -THISISMOSTIMPORTANT.
2.2.6 Remove the two pads, (taking care not to damage the electrode and discharge switch) and discard them.
2.2.7 Remove any remaining dust from the mesh screens with a soft brush or vacuum cleaner. Tarry deposits (i.e. from
cigarette smoke) may be removed from the screens by careful application of a small amount of methylated spirit.

(away from the centre screen).
2.2.9 Close the Cleaner element carefully, ensuring that the pads do not move off centre.
2.2.10 Close the latches and check that there are no gaps between the pads and the outer frame.

3. FAULTFINDING
3.1 If you feel yourAir Cleaner is not working correctly, remove the Cleaner from the unit and check the amount of dust which
has collected. Clean the Cleaner assembly and replace the pads if necessary.
3.2 Ensure that the pads are completely dry. Damp pads may be dried using a hair drier. If in any doubt, always replace the pads.
3.3 If the unit emits a crackling noise, sparking is occurring in the unit either because a conductive material is caught on the
pads, or the outer screens are bowed in towards the centre screen. Remove the Cleaner assembly, remove and examine the
pads (carefully removing any conductive material that may be causing arcing), and lightly press all around the edges of the
outer screens to ensure that they bow away slightly from the centre screen (refer to Fig. 2). Change the pads if necessary.
