Carrier GAPAB Series User manual

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).

For Troubleshooting

WIRING (continued)
NOTE: The air purifier is to be powered by 115-230VAC/50-60 Hz input voltage.
NOTE: The air purifier must only be powered when airflow is present. An airflow switch is factory-installed on the air purifier. In order
to bypass the airflow switch for troubleshooting, use the special bypass jumper plug include in the parts bag (see Fig. 9). With the
jumper plug in place, the air purifier will be on at all times when connected to electrical line power. The bypass jumper plug is not
to be used for normal operation and is to be used by qualified service personnel only.
TROUBLESHOOTING
If the air purifier shuts OFF during normal operations:
This condition could be caused by the power supply
recognizing that there is something wrong in the air purifier.
The power supply detects air purifier electrical faults and shuts
offthe high voltage for 50 seconds if such a fault is detected. If
4-6 faults have been detected, the power supply will shut OFF
and remain OFF. The air purifier will not turn ON until the
problem has been corrected by the user and the unit has been
reset per the instructions below.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing or servicing system, always turn off main
power to system. There may be more than one disconnect
switch.
