LCDI Power Cord and Plug
This air conditioner is equipped with an LCDI (Leakage Current Detection and Interrup-
tion) 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 deenergized 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 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.
Plug power cord into a wall outlet.
Press the TEST Button, the circuit should trip and cut all power to the
air conditioner.
Press the RESET button for use.
If a test is performed and the indicator light remains ON, the current
leakage has been detected. Do not use the air conditioner or attempt to

Storm Window Requirements
Placing the Unit Inside a Window
A storm window frame will not allow the air conditioner to tilt properly which in turn will
keep it from draining properly.
To adjust for this, attach a board or piece of wood to the sill. The board or wood piece
should have a depth of at least 1-1/2". Make sure the board or piece of wood is approxi-
mately 1/2" higher than the storm window frame. This will allow the air conditioner to
tilt enough for proper drainage. (See Fig.5).
Board or wood piece must be
approximately 1/2"higher than
the storm window frame for
proper drainage
