c. Connect the power cord and the flow sensor cord to the
power supply connector and the flow sensor connector
(see Fig. 7 and Fig. 8).
NOTE: The power cord can be routed through the opposite side
of the cabinet. Zip ties have been enclosed 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

use the special bypass jumper included in the parts bag. With the
bypass jumper in place, the air purifier will be on at all times
when connected to electrical line power (see Fig. 10).

connector leads (in parts bag attached to power cord) and
connect to incoming field power. Attach the ground ring
