With the 120 VAC power turned on at the circuit breaker for the furnace, push the air cleaner ON-OFF switch to the “ON” position (Figure 20). 2. With the furnace blower running, the air cleaner will be operating. An arcing or “snapping” sound may be heard. This will occur occasionally, however the unit is operating properly. 3. With the furnace blower running, the Operating Light should be ON. If the Operating Light is not ON this signifies that the cells need washing, or that trouble exists in the unit. If, after washing the cells, the Operating Light stays off, the cell could be wet, improperly placed in the cabinet or may need servicing. NOTE: NOTE:NOTE:NOTE:NOTE: NOTE: An occasional flicker of the light accompanied by harmless sparking or snapping noise may occur. This is caused by trapping large particles of dirt. If arcing is continuous, the cells should be washed or checked for service problems see Basic SST Service Guide.

For maximum efficiency your air cleaner cell(s) and prefilter( s) should be inspected once a month and cleaned when necessary. Cleaning will usually be required every one to three months, depending upon the particular household circumstances. When cleaning is required the following procedure should be used: CLEANING THE CELLS CLEANING THE CELLSCLEANING THE CELLSCLEANING THE CELLSCLEANING THE CELLSCLEANING THE CELLS 1. Turn the air moving system “OFF.” 2. Push the ON-OFF switch on the power pack to the “OFF” position (Figure 20). Wait 15 seconds and both the power pack and the collecting cell(s) will be automatically discharged. 3. Release the latch on top of power pack and pull the power pack straight away from cabinet at the top. Then lift pack out of ledge at bottom edge of cabinet. Set power pack aside. 4. Remove the cell(s) and pre-filter(s) from cabinet. Using a solution of warm water and low sudsing detergent, soak cell(s) and pre-filter(s) for 20 to 30 minutes. NOTE: NOTE:NOTE:NOTE:NOTE:NOTE: Ionizing wires may become coated causing loss of cleaning ability by the collecting cell. Using a damp cloth, wipe each ionizing wire, exercising care not to damage them. 5. Remove the cell(s) and pre-filter(s) from solution and rinse thoroughly with clean water. 6 Allow cell(s) and pre-filter(s) to drip dry for a mini- mini-mini-mini-mini-minimum of 2 hours. mum of 2 hours.mum of 2 hours.mum of 2 hours.mum of 2 hours.mum of 2 hours. Cell(s) and pre-filter(s) may be tipped at a slight angle to expedite the drip-dry process. 7. Reinstall the cell(s) and pre-filter(s) in the cabinet. 8. Replace the power pack. Turn furnace fan on. After 30 minutes push ON-OFF switch on the power pack to the “ON” position. A moderate amount of arcing or “snapping” may occur at this time, which will indicate that the cell(s) are still damp. If the noise is objectionable, push the ON-OFF switch to the “OFF” position and allow additional time for cell(s) and pre-filter(s) to dry. In some cases the Operating Light will remain OFF during this initial activation of the air cleaner, and this would indicate that the cell(s) are not completely dry. The Operating Light should remain ON while the furnace fan is running once the drying is complete. 8 REPLACING AN IONIZING WIRE REPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIRE REPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIREREPLACING AN IONIZING WIRE 1. Remove all pieces of broken wire. Make sure supports at each end are in good condition and not bent out of shape. 2. Hook the new wire onto the support at one end. 3. Hold your finger against the support at the other end (Figure 21) and hold the ionizing wire between thumb and forefinger as shown or use needle nose pliers. Press inward on spring support. Hook end of wire over small tab at end of support and release. Make sure wire is securely anchor...
