OPERATION INSTRUCTIONS

BEFORE USING YOUR PORTABLE AIR CONDITIONER

• Remove the exterior and interior packaging
• Before connecting the appliance to a power source and operating, let the unit stand upright for a minimum of 4 hours. This will reduce the possibility of a malfunction in the cooling system from handling during transportation.

SWITCHING ON/OFF THE AIR CONDITIONER

• The unit can be switched ON or OFF by pressing the Power button on the control panel or the Power button on the remote control.

COOLING MODE

• In this mode, the air conditioner cools and dehumidifies the room. To activate the cooling function, press the Mode Control button until the GREEN indicator illuminates. When cooling mode is set, the compressor will start in approximately 3 minutes.
  NOTE: In cooling mode, hot air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the hot air.
• The temperature setting range is 61°F to 89°F. To set the temperature, press the + or buttons. The air conditioner has a 5°F temperature cushion; if the set temperature is within 5°F of the ambient temperature, the unit runs in fan only mode. This saves energy and prolongs the life of the compressor. Once the set temperature is achieved, the compressor will turn off and the fan runs continuously to circulate the air within the room.
• To set the fan speed, press the Fan Speed button.In cooling mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.

DEHUMIDIFYING MODE

• In this mode, the air conditioner dehumidifies the room, the compressor will activate intermittently depending on the ambient temperature and the fan speed is set to Low. To activate dehumidifying mode, press the Mode Control button until the PURPLE indicator illuminates.
  When switching between functions, there will be an approximate 3 minute transition time.
• In dehumidifying mode, the exhaust hose does not need to be vented. If the exhaust hose is vented, the room will be cooled as it dehumidifies. To prevent cooling, remove the exhaust hose from the window kit and allow the warm air from the rear to be re-circulated into the room. If room temperature is higher than 77°F, the fan speed can be adjusted. If room temperature is lower than 77°F, the fan speed is set at Low. Note:
• When using dehumidifying mode, venting the exhaust hose to the outside is not required. If vented, the warm air is exhausted to the outside and cooling within the room may occur.
  Additionally, if the exhaust hose is not vented, the unit may require more frequent draining.
• The air conditioner does not have a humidistat in which a specific humidity level can be set.

FAN ONLY MODE

• In this mode, only the fan of the air conditioner runs and circulates the air within the room. To activate fan only mode, press the Mode Control button until the YELLOW indicator illuminates. In this mode, the temperature cannot be set. Subsequently, set the desired fan speed by pressing the Fan Speed button.
• Note: When using fan only mode, venting the exhaust hose to the outside is not required.

COMPRESSOR LOCK OUT

• This portable air conditioner is optimized to operate in an ambient temperature of 64°F – 90°F. The compressor circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents over-heating of the compressor and possible circuit breaker tripping.

TIMER (DELAYED SWITCH ON / OFF) FUNCTION

• This function mode enables a delayed switch ON or delayed switch OFF of the air conditioner. The time (hours) delay can be set, enabled and disabled. The timer is adjustable between 1-24 hours.

SETTING SWITCH OFF TIMER
With the air conditioner operating in any function mode, press the Timer Control button. Then set the desired time delay OFF hours by pressing the + or - buttons. When the delay time set has elapsed, the air conditioner switches off.

SETTING DELAYED SWITCH ON TIMER
With the air conditioner is off, press the Timer Control button. Then set the desired time delay ON hours by pressing the + or - buttons. When the delay time set has elapsed, the air conditioner switches on.

AUTO RESTART
In the event of a power outage, the air conditioner restarts at the previously set function mode and settings when power is restored.

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

During the process of cooling, some water will be extracted from the air into the unit. Most of this water is used to cool and exhausted to the outside. If the unit is operated in high humidity or low temperature environment, water will collect in the reservoir inside the unit. If the reservoir is full, the compressor will stop. To continue the cooling function, please drain the water.
The air conditioner has the capacity to dehumidify up to 81 pints per day. The patented selfevaporating function of the unit fully exhausts all condensation automatically in most environments when humidity is less than 70%. Areas with more than 70% humidity, the self-evaporating function can still exhaust about 98% of the moisture and the remaining 2% of moisture will be collected in the water tank of the air conditioner.
When there is excess water condensation inside the unit, the air conditioner stops running and the RED Stop light illuminates. The Stop light indicates that the water condensation needs to be drained manually:

Manual Drainage

1. Turn off the unit.
2. Carefully roll the unit to a drain location or position a flat container, dish or optional drain bucketaccessory (sold separately) under the drain area of the lower drain port.
3. Remove the drain cover and rubber plug and the condensed water will drain out automatically.
4. Once all the condensed water is drained, replace the drain rubber plug and cover into the drainfirmly.

Continuous Gravity Drainage Option
This option is recommended if uninterrupted operation is desired.

1. Remove the drain plug cover and rubber plug from the upper drain port.
2. Install the drain hose (sold separately) through the drain cover.
3. Thread the drain cover onto the upper drain port.
4. Place the open end of the drain hose downward to an area appropriate for draining.

The hose must be directed downward from the upper drain port to allow the condensed water to flow with gravity.
Note: Please contact support@whynter.com for retail sales information or visit whynter.com for a list of optional accessories.

REMOTE CONTROL

The portable air conditioner can be switched on by the remote control.

NOTE:

• Other appliances in the same room controlled by a remote control (TV, radio, stereo, etc.), may cause interferences.
• Electronic and fluorescent lamps may interfere with the signal transmissions between the remote control and the air conditioner.
• Remove the batteries if the remote control is not used for long periods.

CARE AND MAINTENANCE

Note: Depending on use, it is recommended that the air conditioner be cleaned internally annually. Please contact Whynter at support@whynter.com for internal maintenance cleaning instructions.

Tips:

1. Keep the exhaust hose as short and straight as possible
   The exhaust hose removes heat from the room. It should remain as short and straight as possible without sharp bends or twists to maximize efficiency. If the exhaust hose must be extended, do not exceed 9'.
2. Turn the air conditioner on early
   Turning the air conditioner on early instead of waiting until the hottest point of the day will allow the unit to be more effective. The air conditioner will not have to work as hard to cool the room down and maintain the set temperature.
3. Reduce heat sources
   Direct sunlight, televisions, computers and other heat generating appliances work against the air conditioner by introducing heat into the space.
   • Close window curtains and blinds to keep direct sunlight out
   • Close doors and windows
   • Keep ovens and stoves off
   • Turn off unused lights
   • Add weather stripping around windows and doors
4. Keep the air filter clean
   Regular cleaning will help keep your air conditioner working properly. Dusty filters and vents greatly reduce the airflow and efficiency of the unit.
   • Clean the washable pre-filter regularly
   • Replace the activated carbon filter every 2-3 weeks depending on use
   • Vacuum any accumulated dust from around all vents
