Tools Needed

• Medium Phillips screwdriver;
• Tape measure or ruler;
• Knife or scissors;
• Saw (optional, to shorten window adaptor for narrow windows)

Accessories
Your Window Installation Kit fits windows 26.5 – 48″ and can be shortened for smaller windows.

Window Installation Kit
Step One: Preparing the exhaust hose assembly.
Press the exhaust hose into the window slider adaptor and the unit adaptor. Each adaptor will snap into the exhaust hose automatically with plastic clips.

Step Two: Install the exhaust hose assembly to the unit Align the unit adaptor of the exhaust hose assembly to the groove of the air outlet opening on the back of the unit. Slide the exhaust hose assembly along the direction indicated by the arrow for installation.
Step Three: Preparing the adjustable window slider

1. Depending on the size of your window, adjust the size of the window slider.
2. If the length of the window requires two window sliders, use the bolt to fasten the window sliders once they are adjusted to the proper length.

Note: Once the Exhaust Hose assembly and Adjustable Window Slider are prepared, choose from one of the following two installation methods.

Type 1: Hung Window Installation
Cut the adhesive foam seal A and B strips to the proper lengths, and attach them to the window sash and frame as shown.
Insert the window slider assembly on the bottom sash channel. Use care when installing the window slider assembly, which will now fit very tightly in the opening. Close the sash tightly against the top of the window slider assembly.
Cut the non-adhesive foam seal C strip to match the width of the window. Insert the seal between the glass and the window frame to prevent air and insects from getting into the room.
If desired, install the security bracket with 2 screws as shown. 

Insert the window slider adaptor into the hole of the window slider.

Type 2: Sliding Window Installation
Cut the adhesive foam seal A and B strips to the proper lengths, and attach them to the window sash and frame as shown.
Insert the window slider assembly on the left or right sides of the sash channel. Use care when installing the window slider assembly, which will now fit very tightly in the opening. Close the sash tightly against the other side of the window slider assembly.

Cut the non-adhesive foam seal C strip to match the width of the window. Insert the seal between the glass and the window frame to prevent air and insects from getting into the room.
If desired, install the security bracket with 2 screws as shown.
Insert the window slider adaptor into the hole of the window slider.

Type 2: Sliding Window Installation

Note: To ensure proper function, DO NOT overextend or bend the hose. Make sure that there is no obstacle around the air outlet of the exhaust hose (in the range of 19.7 inches) in order for the exhaust system to work properly. All the illustrations in this manual are for explanation purposes only. Your air conditioner may be slightly different. The actual shape shall prevail.

Note: While operating in cool mode, the exhaust hose will become warm to the touch (This is normal).
Having the exhaust hose overextended can cause radiant heat into the room causing ineffective operation.

Operation Instructions

COOL operation

• Press the “MODE” button until the “COOL” indicator light comes on.
• Press the Up (+) and Down (-) buttons to select your desired room temperature. The temperature can be set within a range of 17°C-30°C162°F-86°F.
• Press the “FAN” button to choose the fan speed.

DRY operation

• Press the “MODE” button until the “DRY” indicator light comes on.
• Under this mode, you cannot select a fan speed or adjust the temperature. The fan motor operates at LOW speed.
• Keep windows and doors closed for the best dehumidifying effect.
• Do not connect the exhaust hose to a window.

Self-Evaporation System

• In cool mode, this unit is made to self-evaporate. This means if you keep the rubber stoppers dosed on the back of the unit, the water will evaporate and you will not have to drain.
• In cases of extreme humidity, you may have some water accumulation that the unit is unable to evaporate. In this case, the unit will beep 8 times, switch to fan mode, and read P1 on the LED display (it will stay like this until the unit is drained). If this happens, you should drain the water from the lower drain (located at the bottom of the unit).
• The top drain is used only if you choose DRY mode.
  * Self Evaporation System works in COOL mode only

AUTO operation

• This feature can be activated from the remote control ONLY.
• When you set the air conditioner in AUTO mode, it will automatically select cooling or fan-only operation depending on what temperature you have selected and the current room temperature.
• The air conditioner will control room temperature automatically according to the temperature point set by you.
• Under AUTO mode, you cannot select the fan speed.

FAN operation

• Press the “MODE” button until the “FAN” indicator light comes on.
• Press the “FAN” button to choose the fan speed. The temperature cannot be adjusted.
• Do not connect the exhaust hose to a window.

Constant Fan operation

• In COOL or DRY mode, press the “MODE” button for 3 seconds to turn on or off the constant fan function. When the function is turned on, the constant fan light will illuminate, identifying that the fan will continuously run for cooling.

SLEEP/ECO operation

• This feature can be activated from the remote control ONLY. Activating SLEEP feature will increase the selected temperature by 1°C/1 °F after 30 minutes. The temperature will again increase (cooling) by another 1°C11°F after an additional 30 minutes. This new temperature will be maintained for 7 hours before returning to the originally selected temperature. This ends the Sleep/Eco mode and the unit will continue to operate as originally programmed. NOTE: This feature is unavailable in FAN or DRY mode.

Other features
AUTO-RESTART
If the unit shuts off unexpectedly due to power outage, it will restart with the previous function setting automatically when the power resumes.
WAIT 3 MINUTES BEFORE RESUMING OPERATION After the unit has stopped, it cannot be restarted until 3 minutes time has elapsed. This is to protect the unit. Operation will automatically start after 3 minutes. AIR FLOW DIRECTION ADJUSTMENT – The louver can be set to the desired position manually. – Do not place any heavy objects or other loads on the louver, doing so will cause damage to the unit. – Keep the louver fully opened during operation.

WATER DRAINAGE

• During dehumidifying modes, remove the drain plug from the back of the unit, install the drain connector (5/8″ universal female mender) with a 3/4″ hose (locally purchased). For the models without a drain connector, just attach the drain hose to the hole. Place the open end of the hose directly over the drain area in your basement floor. NOTE: Make sure the hose is secure so there are no leaks. Direct the hose toward the drain, making sure that there are no kinks that will stop the water flowing. Place the end of the hose into the drain and make sure the end of the hose is down to let the water flow smoothly. When the continuous drain hose is not used, ensure that the drain plug and knob are installed firmly to prevent leakage.
  

• When the water level of the bottom tray reaches a predetermined level, the unit beeps 8 times, the digital display area shows “P1”. At this time the air conditioning/dehumidification process will immediately stop. However, the fan motor will continue to operate (this is normal). Carefully move the unit to a drain location, remove the bottom drain plug and let the water drain away. Reinstall the bottom drain plug and restart the machine until the “P1” symbol disappears. If the error repeats, call for service.
  NOTE: Be sure to reinstall the bottom drain plug firmly to prevent leakage before using the unit.
