INSTALLATION

How to Install the Unit

To prevent vibration and noise, make sure

the unit is installed securely and firmly. Install the unit where the sunlight dose not

shine directly on the unit. The outside of the cabinet must extend out-

ward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will

prevent heat radiation of the condenser. Restriction of outside air will greatly reduce

the cooling efficiency of the air conditioner.

Awning

Cooled air

radiation

CAUTION

● All side louvers of the cabinet must remain exposed to the outside of the structure.

Install the unit slightly tilted so the back is

slightly lower than the front (about 1/4"). This will force condensed water to flow to the outside.

Install the unit with the bottom between

30" ~60" above the floor level.

Fence

Clearance

Proper clearance enhances the cooling efficiency of the product.

If a storm window presents interference,

fasten a 2” wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame.

(See drawing.) The top of the wood strip on

the inside sill should be approximately ¾” higher than the storm window frame or wood strip on the outside sill to help condensation to drain properly to the outside.

If necessary, install a second wood strip

(same thickness as first strip) in the center of sill flush against the back off the inner sill. This will raise the L bracket as shown in the drawing.

Power

Press to turn the air conditioner ON or OFF.

Sleep Mode

This mode keeps operating noise to a minimum and turns the air conditioner off after a set time. The timer can be set from 1 to 7 hours.

● In the Sleep Mode, the setting temperature increases by 2 °F after 30 minutes and additional 2 °F after another 30 minutes for a more comfortable sleep.

● The setting temperature increases up to 4 °F from the preset temperature.

Delay ON/OFF Timer

Delay ON - When the air conditioner is off,

set it to automatically turn on from 1 to 24 hours later, at its previous mode and fan settings.

Delay OFF - When the air conditioner is on, set it to automatically turn off from 1 to 24 hours later.

NOTE

● Each press of the Timer button advances the timer by 1 hour. After the last press the display returns to the temperature setting.

Operation Mode

Press the Mode button to cycle between 4 types of air conditioner operation: Energy Saver / Cool / Fan Only / Dry.

Energy Saver - In this mode the

compressor and fan turn off when the set temperature is achieved. Approximately every 3 minutes the fan turns on to allow the unit sensor to accurately determine if more cooling is needed.

Cool - This mode is ideal on hot days to cool and dehumidify the room quickly. Use the Temp room temperature and use the Fan Speed button to set the desired fan circulation speed.

Fan Only - In this mode the fan circulates air but the compressor does not run. Use the Fan Speed button to set fan speed to High, Medium or Low. In this mode, you cannot adjust the set temperature.

Dry - This mode is ideal for rainy and damp days to dehumidify the room rather
