BENEFITSHelps provide relief for allergy or asthma suffering.Helps prevent damaging black dust from stainingwalls and furnishings, reducing the amount of timeand money spent cleaning and redecorating.Helps eliminate unpleasant odors (with use ofoptional Carbon Filters).Helps protect heating/cooling equipment,prolonging the operating efficiency.HOW IT WORKSThe High Efficiency Electronic Air Cleaner operateson the principle of electrostatic precipitation. Millions ofairborne pollutants are carried through the return airducts of the heating/cooling system and treatedthrough four stages of filtration.The prefilters (2) remove all large visible particlessuch as lint. Smaller particles then pass through a twostage electrostatic collecting cell (2). First, particles aregiven a powerful positive electrical charge by theionizing wires. Second, charged particles move into thecollecting area where they are attracted to a series ofgrounded plates. Pollutants are held in this section likea magnet until washed away during cleaning. Lastly,clean air passes over activated carbon filters (3) forodor removal (optional).The Electronic Air Cleaner, available in four modelswith air flow capacities of up to 1200, 1400 and 2000CFM (2040, 2380 and 3400 m³/hr), is adaptable to allresidential forced air heating or cooling systems.

NEVER put screws orrivets into the removable power box.When the air duct does not fit Air Cleaner opening,a gradual transition is recommended to reduce airturbulence through Air Cleaner and to increase itsefficiency. There should not be more than 20º ofexpansion used on each side of transition fitting.Do not reduce ductwork to a smaller Air Cleaner orit will increase velocity of airflow.4. If Air Cleaner is installed adjacent to an elbow orangle fitting, turning vanes are recommended toimprove air distribution across the collecting cells.5. After Air Cleaner has been secured, seal seamsairtight with duct tape or caulking to prevent dustfrom entering the system.6. Replace prefilters, collecting cells and carbonfilters. Make sure arrow on cell is pointing towardsthe fan. The cell handle may need to berepositioned if the airflow is in a different directionthan the left to right set up. The handle should facethe door. Close access door.

WiringWiring should only be performed by qualifiedpersonnel only. All wiring must comply with allapplicable codes and standards. The voltage of thepower source must match the voltage indicated on theAir Cleaner. The Air Cleaner should operate ONLYwhen the system fan is running. Make sure the AirCleaner is properly grounded.WARNINGElectrical shock can cause injury or death. Be certainmain line disconnect switch is off before wiring.Wire the Air Cleaner directly to the 120 V powersource. The APS will power the Air Cleaner when thereis sufficient airflow to activate the sensor. See Fig 5 &6.Note: The power switch will be lit even if there is noairflow.SYSTEM CHECKPerform the following system check before operation.1. Replace prefilters, collecting cells and carbonfilters. Close access door.2. Turn Air Cleaner power switch ON. Ensure systemfan is operating. Both the power switch light andperformance indicator light should be lit. The powerswitch light indicates the Air Cleaner has unitvoltage. The performance indicator light shows thatthe Air Cleaner is operating.Note: There may be some arcing or snapping soundsfrom the collecting cells. This is normal when the unit isnew. In about 2 weeks, as the sharp edges of the cellsbecome smoother, the arcing will disappear.OPERATIONThe Air Cleaner will run as long as there is airflowthrough the ducts. The Air Cleaner will not run if thesystem fan is off. For proper operation, follow thesesimple steps:1. Run heating/cooling system fan continuously, andon low speed if available.2. Remove furniture or carpets which block return airgrilles throughout your house, so that air movesfreely to the furnace/ air conditioner.3. Check for proper operation of the system fan.WHITE DUSTFig. 5Models ASAS-10ASC/GSAS-10ASC, ASAS-11ASC/GSAS-11ASC(with Air Proving Switch)After installation of the Air Cleaner, you may noticesome white dust on tabletops and shelves. Most largeparticles such as lint, are too heavy to remain airborneand tend to settle quickly, never reaching the aircleaner.This white visible dust is normally referred to as“clean dust.” As the Air Cleaner is removing the darkand staining particles from the air, the lint will also becleaner.Lint dust is most noticeable on dark furnishings; inhomes containing new carpeting; and where there is alot of household traffic from occupants and pets. Toreduce lint dust, use continuous fan operation and keepreturn vents unrestricted to create an efficient airflow.Note: The Air Cleaner does NOT produce more lint ordust.MAINTENANCEIt is important to follow a scheduled maintenance formaximum performance of the Air Cleaner.CAUTIONMake sure to turn Air Cleaner and system fan OFFbefore performing any maintenance or removing anycomponents.Fig. 6Models ASAS-12ASC/GSAS-12ASC, ASAS-18ASC/GSAS-18ASC(with Air Proving Switch)Cell And Prefilter CleaningThe collecting cells and prefilters must be cleaned on aregular basis for the Air Cleaner to function at its peak

efficiency. The frequency of cleaning will vary from onehouse to another. On average, the cells should becleaned every 3 months.1. Remove access door, collecting cells andprefilters.2. Place cells in a laundry tub. Rinse with hot waterand spray completely with DAX Detergent (or anon-chlorine, non-corrosive, non-abrasive liquidhousehold detergent. Allow detergent to run downboth sides of plates and ionizing wires. Let standfor 5 minutes.3. Rinse cells well with hot water (maximum 120 F/49 C). Repeat washing process 2-3 times.4. If dirt remains, fill up laundry tub with water andDAX Detergent (1/2 cup), and dunk cells up anddown until water is dirty. Let cells soak in thesolution for 30 minutes. Then rinse cells well withhot water (maximum 120 F/49 C).5. Tilt cells on 45 angle on their short side, witharrows pointing sideways. Allow to dry completely,approximately 10-24 hours.6. To wash prefilters, spray with DAX Detergent, rinseand let dry. Do not wash in the same water ascollecting cells.7. Place cells and prefilters back into cabinet. Closedoor and turn power switch ON. If the performancelight does not come on or arcing occurs, turn AirCleaner OFF, remove cells and allow more dryingtime.Fig. 7 — DAX Detergent and Carbon Filters areavailable from your installer or dealer.DAX32 oz Spray BottlePart #9900CAUTIONDamage to cells may occur if improperly handled orwashed. Do not wash cells in a dishwasher. Neveruse any object to clean between the cell plates, asthis may cause damage to plates or ionizing wires.Never place cell in oven to dry. The edges of the cellmay be sharp - handle with care.Activated Carbon Filter ReplacementCarbon filters help remove odors from the air. If theAir Cleaner has been equipped with optional carbonfilters, they should be replaced every 3 - 6 months.Filters are NOT washable. Replacements are availablethrough your installer or dealer. To replace filters,perform the following functions: Air Cleaner power switch OFF.Turn off system fan.Open access door.Remove collecting cells from Air Cleaner.Pull out used carbon filters. If the carbon filters donot slide out easily, tilt them on a 45 angle andthey will fall out.6. Put new carbon filters into Air Cleaner. Spacefilters evenly across the discharge opening of AirCleaner. Never put more than 3 carbon filters inthe Air Cleaner, as this may cause a problem withairflow.Replacement Carbon Filters:A/ GSAS-10, A/ GSAS-11 Set of 3Part #1156-3A/ GSAS-12, A/ GSAS-18 Set of 3Part #1856-3SERVICEWARNINGElectronic Air Cleaners use high voltage (lowamperage). Only trained personnel should performservice. Use caution. Electric shock can cause injuryor death.Testing Air Proving Switch (APS)The APS sensor must protrude through the plasticbushing to work effectively. The sensor is verysensitive and operation may be affected by coldbasement temperatures, an air exchanger, or a freshair duct connected to the cold air return just upstreamof the Air Cleaner.The APS uses a Triac in its output circuit, whichaffects the voltage sine wave. Using a regular digitalvoltmeter will give a false reading. To check the outputfrom the APS, use a true RMS (root mean square)meter to measure the output at terminals 1 and 4 of theAPS. The output should be between 105 and 115 VAC,depending on the airflow across the sensor.A neon lamp may be used to test the output of theAPS. Place the leads of the lamp across terminals 1and 4 of the APS, or across the 120 V input of thesingle output power board. If the lamp lights, thevoltage is sufficient for operation.When the Air Cleaner is turned on without airflow,the APS sensor heats up and after 30 seconds, opensthe circuit to turn off the power board. When the fanstarts up (the sensor is cooled), the circuit will close,the power board is turned on, and the performancelight will come on.The light on the power switch will be lit even whenthe APS is open. If the power board fails to come onwith the fan on, check that the sensor is properly setdown, through the plastic bushing, in front of the powerbox. To check the APS for proper operation, turn theunit on and activate. The power board should come onimmediately, and then turn off in 30 seconds as thesensor heats up. To check sensor, blow directly on itlightly. This should activate the power board within 10seconds. Service the sensor carefully. The sensorleads are 120 V.

Replacing An Air Proving Switch (APS)Before replacing the APS, turn off the power to theAir Cleaner at the source.1. Disconnect wiring from terminals 1, 2, 3, and 4 onthe APS. See Fig. 5 and 6.2. Release circuit board from plastic spacers bypinching end of spacer and pulling board out.3. Install new APS on plastic spacers. Ensure sensorprotrudes slightly through plastic bushing.4. Connect wiring to terminals on APS. Wiring frompower source is connected to terminals 2 and 3.Wiring to power board is connected to terminals 1and 4.5. Test the new APS.Testing For High Voltage At Power BoardA high voltage meter capable of measuring up to10,000 VDC is required to test the voltage.1. The Air Cleaner should be ON with the doorclosed. The unit fan should be running. The AirCleaner should be on at least 5 minutes to allowvoltage to stabilize.2. Remove cover from power box.3. Connect the ground of the high voltage meter to anunpainted surface in the power box.4. Check terminals HV1 and HV2 (where applicable)on the power board to determine if voltage ispresent.5.
