NOTE: The LCDI device is not intended to be used as a switch.
Once plugged in the unit will operate normally without the need to reset the LCDI device. If the LCDI device trips and requires resetting the cause of the trip should be identified prior to further use of the PTAC.
If the device fails to trip when tested or if the power supply cord is damaged it must be replaced with a new supply cord obtained from the product manufacturer, and must not be repaired.
