LCDI POWER CORD & PLUG
This air conditioner may be equipped with an LCDI (Leakage Current Detection and Interruption) power cord and plug as
required by US National Electric Code 440.65. The cord consists of a length of shielded flexible cord with no termination on
the load side and an LCDI attachment plug on the line side.
Three phase units are not required to have an LCDI.
The LCDI power cord and plug will remove the supply source via electrical disconnect 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 device
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 hazard 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:
1. Plug power cord into proper outlet.
2. Press the TEST Button. Circuit should trip, cutting power to the unit and turning the green “POWER READY” light off.
3. Press the RESET Button to restore power: green light should be lit.

supply circuits.
4. The cord and plug are intended for indoor use only.
INSTALLATION INSTRUCTIONS
BEFORE INSTALLING:
ELECTRICAL REQUIREMENTS:
Unpack the unit, remove it from the pallet carefully and inspect it for any possible shipping damage. All units are
thoroughly run tested and carefully packaged at the factory. If there is any damage, note it on the delivery receipt and
file a claim with the carrier immediately. It is important to read this installation manual carefully. Store this manual
in a safe place for future reference.
Check the data plate on the back panel to make sure the power supply matches the requirements. Refer to
“Specifications” section for voltage and fuse/breaker recommendations. For proper NEMA receptacles, refer to
“Electrical Service Plug/Receptacle Chart.”
Operating the unit on improper voltage will void the warranty.
CAUTION: AN EXTENSION CORD CAN BE USED PROVIDED IT IS RATED AT LEAST 20 AMPS@115VOLTS, or
20 AMPS @ 250 VOLTS WITH GROUNDING-TYPE ATTACHMENT PLUG AND GROUNDING TYPE CONNEC-
TOR (LOAD FITTING).
Do not remove or modify the cord connected LCDI (Leakage Current Detection & Interruption) or AFCI (Arc Fault
Circuit Interrupter). Do not connect the unit to an outlet that is also being used for other electrical appliances or
loads. It may cause nuisance tripping of the LCDI or circuit breaker.
