Carrier GAPAB Series Installation Instructions Addendum

Installation instructions Addendum
The GAPAB air purifier has recently been upgraded with new power supply hardware. This addendum replaces the "Wiring" section on
pages 4 and 5 of the installation instruction manual for proper installation and operation of the air purifier.
WIRING
a. Ensure power has been removed from the heating and
cooling system.
b. Turn the air purifier power switch off.
c. Connect the airflow switch and power cord to the power
supply connectors (see Figs. 7 and 8).
d. Secure the power cord ground wire to the ground terminal on
the cabinet using the screw provided in the ground terminal
(see Fig. 8).
e. Route the power cord through the nearest cabinet hole and
protect with the enclosed cable connector. The screws on
the cable connector should be tightened to 9 in-lb. Zip ties
have been enclosed (in parts bag attached to power cord) to
secure the power cord to the side of the power supply.
f. Attach the quick connect terminals to the fused power
connector leads (in parts bag) and connect to incoming field
power. The terminals are polarity neutral and can be
connected in either polarity. Attach the ground ring to Pan
coil chassis ground (see Fig. 10).
