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.

Pull out about 6” of one end of the exhaust hose.
Install the flat mouth and sliding round exhaust connector on the exhaust hose by turning counter-clockwise. See Fig. 16 and 17
Push in the exhaust hose into the air outlet port at the back of the unit. See Fig. 18
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 info@whynter.com 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.

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
