Recommended Ground Method
For your personal safety, this air conditioner must be grounded. This air conditioner is equipped with a 3 prong power
supply cord with a grounded plug. To minimize the possibility of electrical shock, the cord must be plugged into a 3 prong
outlet and grounded in accordance with all local codes and ordinances. If a 3 prong outlet is not available, it is the cus-
tomer’s responsibility to have a properly grounded 3 prong outlet installed by a qualified electrician.
LCDI Power Cord and Plug
- NEMA 6-20P
This air conditioner is equipped with an LCDI (Leakage Current Detection and Interruption) power cord and plug as
required by US National Electric Code 440.65. This cord consists of a length of shielded flexible cord with no termination
on the load side and a LCDI attachment plug on the line side.
The LCDI power cord and plug will remove the supply source via electrical disconnect (circuit trip) if the nominal current
leakage between the cord shield and either load conductor exceeds a predetermined value. The cord will remain de-
energized until the devise has been manually reset. This is intended to reduce the risk of a fire in the power cord or
combustible materials nearby. The cord shields are not grounded and they must be considered a shock hazards if
exposed. The cord shield must not be connected to ground or to any exposed metal.
The test and reset buttons on the LCDI Plug are used to check if
the plug is functioning properly. To test the plug:
1. Plug power cord into a wall outlet, the power light will turn
on.
2. Press the TEST Button, the circuit should trip and cut all
power to the air conditioner. The power light will turn off.
3. Press the RESET button for use. The power light will turn
back on.
If a test is performed
and the indicator light remains ON prior to
pressing RESET, current leakage has been detected. Do not
use the air conditioner or attempt to reset the LCDI Plug. Con-
tact Customer Service for troubleshooting recommendations.
