The iWave-R is a self-cleaning, no-maintenance air ionization generator designed for residential duct air conditioning systems. It utilizes needlepoint bipolar ionization to actively treat air, reducing certain bacteria and viruses, odors, smoke, and airborne particles. The device is applicable to systems up to 6 tons (2400 CFM) and features universal mounting options and a multi-voltage input. Installation requires disconnecting power to the air handler and mounting the unit within the ductwork or near the indoor fan.
Device Overview and Functionality
The iWave-R functions by generating positive and negative ions that actively clean the air as it passes through the HVAC system. This ionization process aims to reduce the presence of certain bacteria and viruses within both the cooling coil and the occupied living space. Beyond pathogen reduction, the iWave-R is designed to mitigate odors, smoke, and static electricity, as well as other airborne particles. The technology has been implemented in over 200,000 applications.
The device does not create “black walls” as some negative-only ionizer products may, according to provided documentation. It is validated to meet UL 867 ozone requirements.
Installation Procedures
Proper installation of the iWave-R requires adherence to specific guidelines to ensure optimal performance and prevent premature failure. The initial step in the installation process is to disconnect power to the air handler.
The iWave-R offers several mounting options:
- Duct Mounting: The unit can be mounted either internally or externally on the ductwork. For external duct mounting, a three-inch diameter hole must be cut or drilled.
- Magnetic Mounting: The iWave-R is designed with integral magnets, allowing for attachment to metal surfaces near the fan inlet (shaft side) within the air handler.
- Screw Mounting: Alternatively, the device can be secured using screws. If mounting on the fan housing, short-length self-tapping screws are recommended to avoid impairing fan operation.
Regarding placement within the duct system, the documentation specifies different strategies based on the primary concern:
- Coil Treatment: If the primary goal is to treat the cooling coil, the iWave-R should be mounted before the coil.
- Occupied Space Treatment: If the primary goal is to treat the air in the living space, the iWave-R should be installed on the supply side of the coil.
- High Humidity Regions: In areas with high humidity, installation on the supply side of the coil is recommended.
A critical installation requirement is maintaining a minimum of two inches of clearance between the high-voltage emitters and any other metal surfaces or wires to prevent grounding and potential device failure. The documentation emphasizes ensuring airflow across both brushes simultaneously, comparing the airflow to a football passing through a field goal post.
Technical Specifications
The iWave-R possesses the following technical specifications:
- Universal Voltage Input: 24VAC to 240VAC
- Power Consumption: Less than 10 VA
- Frequency: 50/60 HZ
- Air Flow Capacity: 2400 CFM (up to 6 tons)
- Dimensions: 6" L x 4.8" W x 2" D
