iWave-R Installation Instructions Continued
CRITICAL: Make sure air flows across both brushes at the same time, like a football
through a field goal post.
CRITICAL: The iWave-R is designed for flush, external duct mount installations as an
optional install. Ensure in all installations that other metal surfaces/wires are kept a
minimum of two inches away from the tip ends of the high voltage emitters to prevent
grounding, leading to premature failure.
1. The iWave-R has universal voltage capability, connect 24VAC to 240VAC voltage input,
whatever is most convenient for quick installation. Although the device only pulls 10
watts, sometimes a dedicated 24VAC power supply may be necessary depending on
the current load on the transformer for other system accessories.
2. Unit may be powered 24/7 or may be interlocked with indoor fan – unit only purifies when air is flowing. If unit is wired
with the fan, the quickest air purification to address an air concern is to let the fan/iWave-R run continually for 72
hours. Leaving the fan continually in the ‘on’ position will provide the best ongoing air purification in the house.
3. Wiring: The iWave-R has a patent-pending universal voltage 24VAC to 240VAC input capability. The red wire (marked
‘AC’ on label) is for 24VAC to 240VAC voltage input. The black wire (marked ‘N’ on the label) is the neutral leg for
24VAC or 120VAC; or the other hot leg for 208/240VAC. The green striped wire is ground, marked ‘G’ on the label. The
brown wires (marked ‘A’ on the label) are leads to a normally closed alarm contact – see step 7.
4. The iWave-R is equipped with an alarm contact option to provide a visual indicator outside of the air conditioning
system to let the homeowner know that it is in normal operation or if there is a fault. The alarm contact, a normally
closed contact, rated at 240 VAC/1A, will require a power source and visual indicator, such as a LED. In normal mode,
the LED will stay illuminated. If the device goes into default mode, the LED will not light. If a homeowner wants a
remote indication of iWave-R status, it is recommend that the 24VAC light (bought separately) be powered through
the alarm contacts and sent to a remote wall.
5. When powered up, a green LED on the iWave-R will illuminate; the ionizer is working and the stepper motor for the
cleaning feature is in the home position. If the light is not illuminated, check voltage to the iWave-R. If there is power,
the unit has a 240VAC/1A in-line fuse, check the fuse.
6. Self-Cleaning/Program Feature: The patent-pending iWave-R has a self-cleaning feature to ensure it is always
operating at peak performance over its design life. The functions for the button include:
a. While in normal operation mode, press the button once, the LED light will flash and the stepper motor starts an
on-demand cleaning cycle.
b. While in cleaning cycle (after step ‘a’ above), press the button and hold for 3 seconds, it goes into the mode of
setting the cleaning cycle intervals. The iWave-R is designed to be programmed for 1, 3, 5, or 10 day cleaning cycle
intervals. The iWave-R is factory preset for cleaning the emitters every third day; this is adequate for most
applications and will not need to be reprogrammed in the field.
While in the cleaning mode (with LED flashing and cleaning feature working):
a. Press the button and hold for 3 seconds, the LED will flash once every second and the motor works once every day.
b. Press the button twice (the first press hold for three seconds), the LED will flash twice every second and the motor
works once every 3 days. This is the factory preset program.
c. Press the button three times (the first press hold for three seconds), the LED will flash five times every second and
the motor works once every 5 days.
d. Press the button four times (the first press hold for three seconds), the LED will flash ten times every second and
the motor works once every 10 days.
The iWave-R remembers the programmed cleaning cycle days. After the power source is removed and applied again,
the iWave-R will automatically operate and go back to the previous days.
Note: The iWave-R is designed to be a long term IAQ investment, not requiring ongoing maintenance of replacing
expensive parts every year or two like other market approaches. The ion emitters (fiber brushes) used in the iWave-R
are designed to where they could easily be replaced after many years in service; in the unlikely event they ever
needed to be replaced. Replacement requires a Phillips screwdriver and a few minutes; contact Nu-Calgon for further
questions.
