WIRING AND START UP
1. Install a grounded (earth ground) 120-volt single receptacle outlet in accordance with NEC Standards and local codes, into which
the EAC will be plugged. This outlet is to be live only when the furnace/air handler blower is running.
For equipment with EAC terminals:
A. Install a single-receptacle outlet to the furnace/air handler wired as shown in Figure 12.
B. Use a marker or label to identify the outlet as “EAC USE ONLY”.
For 120-volt equipment without EAC terminals:
A. Use the Model 51 Current Sensing Relay to wire a single receptacle outlet as shown in Figure 13. Refer to the instructions
provided with the Model 51 for details on wiring requirements.
B. For blowers that are 1/2 hp or larger, clamp the Model 51 around the common wire of the blower – see Figure 14.
C. For blowers that are less than 1/2 hp, clamp the Model 51 around two wraps of the common wire as shown in Figure 14.
D. Use a marker or label to identify the outlet as “EAC USE ONLY”.
For 240-volt equipment without EAC terminals:
A. Install a 2:1 step down transformer to get 120-volt service. Use the instructions provided with the transformer to ensure it
is properly installed. Do not use ground as the common connection for the outlet.
B. Follow the instructions “For 120-volt equipment without EAC terminals:” above.
2. Press the power cord into the slot in the side of the power pack (door) so that it is directed toward the installed outlet.
3. Install the door on the housing (with the inner assembly installed in the housing). Place the bottom of the door on the lower door
retainer, then swing the door toward the upper door retainer and snap into place.
4. With the door ON/OFF switch in the OFF position, plug the door into the installed outlet.
WARNING
120 Volts may cause serious injury from electrical shock. Leave power disconnected until
installation is complete.
CAUTION
Do not plug the air cleaner into an outlet that is always live. The outlet must only be live when the
furnace/air handler blower is operating. Failure to properly wire the outlet can result in excessive
ozone production.
5. Restore power to the furnace/air handler.
6. Turn on the heating or continuous fan (whichever uses the slowest fan speed) and verify that the blue light on the door is not
on (see Figure 15).
7. Turn ON the door switch.
8. Verify that the blue light on the door turns on (see Figure 15).
9. If the light is on, turn off the heating or fan and verify that the light on the door turns off. If the light turns off, installation is
complete. If the light on the door does not turn on and off as described, continue with Step 10.
10. If the light stays on after the blower has stopped running, the outlet is continuously live and must be rewired in accordance with
Step 1.
11. If the light flashes on, then turns off, or if the light does not come on at all, refer to the TROUBLESHOOTING section on page 8.
