Important Installation Requirements
Failure to comply with these requirements will result in voided warranty, improper installation,
and service callbacks.
Personal Safety
• Wear safety glasses while installing the unit.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local codes for plumbing, electrical, and mechanical
considerations.
Before Mounting
• Using the figure on the cover and the lists on the inside cover, make sure that you have all the components
for your Resideo Electronic Air Cleaner and the tools to install it.
• Ensure airflow direction through the Resideo Electronic Air Cleaner matches the arrows on the electronic
cell. The arrows should point in the direction of the airflow.
• Choose a location that is readily accessible for checking and cleaning the cells. Allow at least 13 in.
(330 mm) in front of the access door for removing the metal mesh prefilter, media postfilter and electronic
cell. Allow enough room above the power supply so it can be serviced without removing pipes, ducts, or
other heating system components.
• Install the electronic air filter where the temperature will not exceed the ratings in the Specifications.
• Do not mount in the supply air duct.
NOTE: Generally, the best location is in the return air duct next to the blower compartment so the Electronic
Air Cleaner can help to keep the blower motor and evaporator coils clean.
If Replacing an Old Air Cleaner
If the Resideo Electronic Air Cleaner is not identical in size and shape to the existing air cleaner, before
performing a retrofit installation, you might need to add duct transitions to ensure a smooth air flow
For optimum system performance, clean the cells every six to twelve months (before heating season and
before cooling season). Adjust the schedule to you needs, but clean the cells at least once per year.
NOTE: Before carrying out any cleaning or maintenance activity, the product must be disconnected from the
electricity.
Choosing a Mounting Position
The Electronic Air Cleaner mounts in any position within the return air duct, usually next to the furnace blower
compartment, but the arrow on the cartridge must point in the same direction as the airflow. See Figs. 1-8 for
proper location of the Electronic Air Cleaner for a variety of furnace installations.
NOTE: The Electronic Air Cleaner cabinet is sturdy enough to easily support the weight of the furnace and
evaporator coil.
