Wiring the 1620/2020/2520 (Air Handler) Honeywell Enhanced
Air Cleaner
STEP ONE:
Wiring the 1620/2020/2520 (Air handler)
a. Ensure power has been shut off from the heating and cooling system.
b. Turn the Honeywell Enhanced Air Cleaner power switch off.
c. Plug the power cord and the airflow switch cord into their power supply connectors (see Fig. 11).
d. Secure the power cord ground wire to the ground terminal on the cabinet using the screw provided in
the ground terminal (see Fig 11).
NOTE: The power cord can be routed through either side of the cabinet. As needed, use the enclosed Zip
ties to secure the power cord to the side of the power supply.
NOTE:
Cable connector and block-off plates will need to be removed and re-installed if the power cord is
re-routed. Screws on the cable connector clamp should be tightened to 9 in-lbs. torque.
NOTE:
The Air Handler Honeywell Enhanced Air Cleaner is to be powered by 208 to 230 VAC at 60 Hz.
NOTE:
The Honeywell Enhanced Air Cleaner should only be powered when airflow is present. An airflow
switch is factory-installed. See Fig. 1 on page 4 and Fig. 14 on page 16. In order to bypass the
airflow sensor for troubleshooting, use the special bypass jumper plug (see Fig. 12) included in the
parts bag. With the bypass jumper in place, the air cleaner will be on at all times when connected
to electrical line power. The bypass jumper is not to be used for normal operation.
e. Attach the quick connect terminals to the fused power connector leads (in parts bag attached to power
cord) and connect to incoming field power. The terminals are polarity neutral and can be connected in
either polarity. Attach the ground ring to air handler chassis ground (see Fig. 13 on page 16).
