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:

1. Plug power cord into wall outlet, the LED light will turn on.

2. Press TEST Button, circuit should trip, cutting power to the air conditioner. When this occurs,
the LED light will turn off.

3. Press RESET button to restore power to the unit. Once power is restored, the LED light will turn
on again.

If test button is pressed and unit can still be turned on, current leakage has been detected. Do not use the air
conditioner or attempt to reset the LCDI Plug. Contact Customer Service for troubleshooting recommenda­tions.

Note: Your unit’s power cord may
differ from the one shown.

WARNING:

1. DO NOT press the TEST button while the air conditioner is operating.

2. The TEST and RESET buttons should not be used as “ON” and “OFF” switches.

3. The cord and plug are not intended to offer protection to externally connected loads or supply circuits.

4. The cord and plug are intended for indoor use only.

WINDOW VENTING KIT

ASSEMBLY & INSTALLATION

When the unit is operating in air conditioning mode, the unit draws in indoor air and exhausts hot air out of the room
to complete the air exchange. The Window Kit must be installed when operating the unit in air conditioning, dehu­midification and heating modes. When the unit is operating in Fan Mode, no outdoor air exchange takes place. The
window kit and exhaust hoses do not need to be installed when the unit is used as a fan.

The supplied window kit can be installed in sliding windows and sliding glass doors up to 7 ft. long
(approximate length). When installed, be sure to keep the exhaust hoses and short and straight as possible for
maximum efficiency.

PARTS & ASSEMBLY

*The two hoses' size are different

WINDOW KIT ASSEMBLY

UNIT OPERATION

BUCKET FULL INDICATOR

When the Internal Water Tank is full, the Bucket Full light will illuminate and the unit will automatically
shut down. The air conditioner will resume normal operation once Internal Water Tank is emptied.

INTERNAL WATER TANK

When the room temperature is low and the indoor humidity is high, the air conditioner may not be able to
evaporate some of the moisture fast enough. When this happens, the water will accumulate in an internal
water tank inside the unit. When this tanks becomes full, the unit will automatically shutdown and illumi­nate the Bucket Full indicator.

HOW TO INSTALL CONTINUOUS DRAIN OPTION:

1. Place the Portable AC on a level surface.

2. Remove the cap on continuous drain port on the back of the unit to access the Continuous Drain Port.

3. Thread a garden hose (not supplied) onto the accessible Continuous Drain Port.

4. Lead Garden Hose to a floor drain and cut to length.

5. Make sure that there are no kinks or knots in the garden hose.

6. Turn on the unit and gravity draining will begin automatically.

MAINTENANCE

HOW TO DRAIN THE INTERNAL WATER TANK

*You will need a small pan, approximately 1” high to catch the water coming out of the water tank. Once
the water tank is empty, the unit will resume operation within a few minutes.

1. Do not move the unit when the water container is full. (Water will spill out)

2. Place a small pan under the condensation drain hole on the bottom side of the unit.

3. Remove the drain plug from the condensation drain hole. The condensate water will drain out automati­cally.

4. When the drain pan is full, install the drain plug back onto the condensation drain hole to stop the water

flow.

5. Empty the drain pan.

6. Repeat steps 2-5 until all the water is emptied.

NOTE: Once the condensate tank has been emptied, firmly press the drain plug back onto the condensa­tion drain hole (Fig 15.1). It is not advised to use continuous drainage when the room temperature is higher
than 90˚F.
