Never place any obstacles around the air inlet or outlet and allow at least 20 inch of clearance for efficient air-conditioning.  

Cool or Auto Mode: Install Hose 

Dehumidify or Fan Mode: Remove Hose 

Exhaust Hose Installation 
When you use this air conditioner unit, hot air must be exhausted out of the room to complete the air exchange of the condenser. When the unit is operating in Dehumidify or FAN only mode, no exhaust is required. 

1. Pull out about 6” of one end of the exhaust hose.
2. Install the flat mouth and sliding round exhaust connector on the exhaust hose by turning counter-clockwise. See Fig. 16 and 17

3. Push in the exhaust hose into the air outlet port at the back of the unit. See Fig. 18

   

4. Only extend the exhaust hose to the necessary length. We do not recommend extending the exhaust hose more than 8' long. If you are interested in purchasing an additional 4’ exhaust hose please contact [email protected] for retail sales information.

NOTE

• The duct can be compressed or extended moderately according to the installation requirement, but it is desirable to keep the exhaust hose length to a minimum.
• Do not bend the exhaust hose
• Make sure that there are no obstructions around the air outlet of the exhaust hose in order for the exhaust system to work properly

Air filter Installation 
Your Whynter portable air conditioner is equipped with a washable Pre-Filter and an Activated Carbon Filter. The washable air filter removes large particles such as dust, pet hair and dander.   The Activated Carbon filter is designed to remove smoke and other odors. It is recommended you replace the Activated Carbon filter every 2-3 months or as needed. 

WARNING: NEVER OPERATE THE AIR CONDITIONER WITHOUT THE AIR FILTER 

Window kit Installation 
When you use this air conditioner unit, hot air must be exhausted out of the room to complete the air exchange of the condenser.

NOTE: Keep the louver fully opened during operation.

NOISE LEVEL

Portable air conditioners may make sounds that are not familiar to you. The sounds listed below are normal. Noise reflecting off hard surfaces such as a floor or wall can make the sounds seem louder than they actually are.

• The compressor may make a pulsating or high-pitched sound
• Water running from the evaporator to the water tank may make a splashing sound
• Refrigerant flowing may make a gurgling sound
• Fan sound may come from front and back air vents

WATER DRAINAGE

Continuous drainage
In COOL or DRY modes, remove the upper drain plug from the back of the unit and install the drain water hose (5/8 universal female mender) with ¾” hose (can be purchased locally). If this part is unavailable from your local hardware store, just attach the drain hose to the drain firmly. The hose will fit snug which should prevent any leaking. Place the open end of the hose directly over the drain area in your basement floor. Please refer to Fig.21 & 22.

Manual drainage
Carefully move the unit to a drain location, remove the bottom drain plug and let the water drain (See Fig. 23). The P1 symbol will disappear and the cooling or dehumidifying function can be started. Be sure to reinstall the bottom drain plug before using the unit.

REMOTE CONTROL

The portable air conditioner can be switched on by the remote control. To transmit signals from the remote control to the air conditioner, point the front part of the remote handset towards the control panel on the air conditioner. Reception of the signal is confirmed by a beep. The maximum signal transmission distance is approximately 8 meters / 26 feet.
