The Whole House Air Cleaner is designed to improve indoor air quality by trapping and collecting small impurities from the air. It can be installed as part of a Communicating heating and air conditioning system or a traditional 24-volt system, offering flexibility in integration with existing HVAC setups. The device consists of several key components: a pre-filter, a field charger, two collection cells, a cabinet, and a power door.
The air cleaner operates by first drawing air through a pre-filter, which captures larger particles like hair and lint. After passing through the pre-filter, contaminants are charged by the field charger. The charged particles then enter the collection cells, where very small impurities are removed and collected. The power door houses the solid-state power supply components that convert 24 Volt AC to the high-voltage direct current required to power the field charger and collection cells.
The unit can operate in two modes: a 24V mode or a communicating mode. A steady amber light on the display indicates 24V mode, while a blinking amber light signifies communicating mode. If no light is present, the unit is not connected. The air cleaner is designed to operate when the indoor fan is running, and a slight sound may be noticeable as air passes through and is cleaned. This sound level can be adjusted by reducing the field charger power setting in the SET-UP mode, which has minimal impact on cleaning efficiency.
The air cleaner's display provides important information to the homeowner, including the operating status and an indication of when the pre-filter or collection cells need cleaning. It also displays fault codes to help identify problems, assisting both homeowners and service technicians in troubleshooting.
To turn on the air cleaner, the POWER button is pressed. The backlit POWER and Filter RESET buttons will illuminate, along with the first Green LED (G1), indicating 24 Volt power is present. When the indoor fan operates, the first LED (G1) will slowly flash, signaling that the field charger and collection cells have power and the unit is operating normally. There is a 10-12 minute time delay between the indoor fan starting and the LED (G1) flashing. This delay can be bypassed by entering and exiting the SET-UP mode.
The SET-UP mode allows for customization of cleaning intervals and power levels. To enter this mode, both the POWER and RESET buttons must be pressed and held for a minimum of 5-6 seconds. The current settings for pre-filter cleaning, collection cell cleaning, and field charger power level are then displayed. The three GREEN LEDs indicate the pre-filter cleaning interval, measured in actual run time of the indoor fan. The default setting is 2 months (10 weeks). The four YELLOW LEDs indicate the collection cell cleaning interval, with a default of 6 months (31 weeks). The three RED LEDs indicate the field charger power level, which defaults to maximum.
To change the pre-filter cleaning setting, the POWER button is pressed once, and then the RESET button is repeatedly pressed to cycle through the time options (1 month, 2 months, 3 months). Once the desired setting is displayed, pressing the POWER button accepts it and moves to the collection cell cleaning settings. The same process applies to the collection cell cleaning settings, cycling through options like 2 months, 4 months, 6 months, or 9 months. For the field charger power level, the RESET button cycles through minimum, medium, and maximum settings. To save new settings and exit SET-UP mode, both POWER and RESET buttons are pressed and held for 5-6 seconds.
The air cleaner also features a safety switch that interrupts power when the power door is removed, ensuring safety during maintenance. An actuator tab in the cabinet closes this switch when the door is properly installed, allowing power to the electronics.
Regular maintenance of the pre-filter and collection cells is crucial for maximum efficiency. The pre-filter should be inspected and cleaned when the red "PRE-FILTER" light is illuminated. The factory setting for this notification is every 2 months (10 weeks) of actual run time, but it can be adjusted to 1 month (5 weeks) or 3 months (15 weeks) based on household conditions (e.g., pets, smokers).
The collection cells should be inspected and cleaned when the last red indicator on the clean/dirty LED light bar is flashing. The factory setting for this notification is every 6 months (31 weeks) of actual run time, adjustable to 2 months, 4 months, 6 months, or 9 months (10, 20, 31, or 46 weeks).
To clean the unit, the air conditioning system must first be turned off at the comfort control (thermostat). Then, power to the air cleaner must be turned off by pressing and holding the POWER button for three seconds. The LEDs will remain on until the voltage has discharged, which takes approximately 15 seconds, indicating it is safe to remove the door. The power/control cable should then be disconnected.
The door assembly is removed by pulling it away from the unit. The pre-filter and collection cells are then removed. Vacuuming is the preferred method for cleaning both the pre-filter and collection cells. It is recommended to perform this outside the home to prevent reintroducing particles into the air. For the pre-filter, vacuum in even strokes across its length, then repeat in the opposite direction. For collection cells, vacuum one side, then turn it over and repeat on the other side. It is normal for collection cells to discolor during operation; vacuuming restores efficiency, not original color.
For collection cells marked "200/200-1" on their frame, washing with a low-pressure water spray (e.g., sink sprayer or garden hose) is an acceptable alternative, especially for residues like tobacco smoke. Warm water may be used. It is important not to use soap or detergent, immerse the cells completely in water, or place them in a dishwasher. After washing, excess water should be drained, and the cells gently tapped on a flat surface to dislodge droplets, then wiped dry. The cells must be thoroughly dry before reinstallation. Collection cells not bearing the "200/200-1" mark should not be washed, as this can degrade the system.
The field charger should only be removed and cleaned annually by a qualified service professional and should never be subjected to water.
After cleaning, the pre-filter is reinstalled, ensuring its airflow indicator arrow points in the same direction as the cabinet's arrow. The collection cells are then reinstalled with their handles folded flat. The power door is reinstalled, the power cord plugged in, and the power button pressed to turn the unit back on. The comfort control (thermostat) should also be reset to the desired mode.
The air cleaner includes fault code display for troubleshooting. Three flashing yellow LEDs indicate 10 consecutive arc fault cycles, leading to a one-hour lockout period. This suggests the pre-filter and collection cells need cleaning to remove trapped material. Three flashing red LEDs indicate other fault types, requiring reference to service facts for more information. The unit repetitively checks for persistent faults, displaying the fault indication until the condition is resolved. A log of the last three faults is recorded even after they are cleared.
When installed with a 900 series comfort control, filter timers can be reset at either the comfort control or the air cleaner. To reset at the air cleaner, the RESET key is held until the respective LED turns off (1-2 seconds). If multiple air cleaners are connected, all timers should be reset simultaneously to maintain a consistent cleaning schedule.
