Honeywell’s Electronic Air Cleaners should only be serviced or replaced by a qualified Heating and Cooling Contractor. Honeywell’s Electronic Air Cleaners contain high voltage, which can be dangerous. There is risk of an electric shock, which can cause injury and or death, as well as damage to the equipment. Improper service, installation of incorrect replacement parts, and/or incorrect installation of the correct replacement parts may compromise the operation of the Electronic Air Cleaner, and also the ability of the heating and cooling system to work properly. Servicing of the Electronic Air Cleaner by any person other than a qualified Heating and Cooling Contractor can void the warranty on the product. Due to liability reasons Honeywell Customer Care can not provide technical support for this device to a customer who is not a qualified Heating and Cooling Contractor.
