HOW IT WORKS
The Whynter compact CFC-free, lead-free, and energy efficient 12,000 BTU portable air condition-er, helps you stay cool while working with better environmental standards and reducing energy con-sumption.
This high output portable air conditioner, specially designed to be mobile, can be easily setup in almost any indoor location and is most commonly used in data closets / server rooms, bedrooms, classrooms and garages / workshops.
This Whynter ARC-126MD portable air conditioner features an ECO-FRIENDLY CFC-free GREEN R-410A refrigerant and lead-free RoHS compliant components.
Operationally, a dual hose portable air conditioner has two main advantages over a single hose unit. A dual hose portable air conditioner can help cool a room faster and will help minimize a negative air pressure situation in the room. If the outside temperature is much higher or more humid than the room, the intake hose can be detached and the unit will function as a single hose unit.

NEVER OPERATE THE AIR CONDITIONER WITHOUT THE AIR FILTER AIR FILTERS
WATER DRAINAGE
The dehumidifying capacity of this unit is 61 pints per day. The patented self-evaporating function of the ARC-126MDB 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 the water reservoir reaches its maximum level, the unit will beep 8 times and the digital display will show P1. When the unit displays P1, all operation modes will be disabled temporarily, while the fan continuously running. The P1 code will disappear when the water is completely drained.
LOCATION
The air conditioner should be placed on a hard and level surface strong enough to support the unit. The unit has casters and it should only be rolled on smooth, flat surfaces. Use caution when rolling on carpet surfaces. Do not attempt to roll the unit over objects. Never place any obstacles around the air inlet or outlet and allow at least 20 inch of clearance for efficient air-conditioning.
EXHAUST AND INTAKE 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 DRY or FAN only mode, installation of the exhaust hose is optional.
WINDOW KIT INSTALLATION
The window kit has been designed to fit most standard vertical and horizontal windows. However, it may be necessary to modify the installation procedures to accommodate your window. Please refer to Fig. 3a and Fig. 3b for minimum and maximum window openings. If your window opening is less than the mentioned minimum length of the window slider kit, the window slider kit can be cut to fit the window opening. Never cut into the exhaust/ intake hose cut-outs on the window slider kit.
If your window opening is larger than the maximum length of the window slider kit, additional material will be needed to cover the open space such as, Plexiglas, PVC plastic, ply wood, etc. Alternately, an additional window slider kit can be purchased to be used in combination with the included kit.
NOTE: When using the window slider kit on a window or sliding door, additional security measures may be needed.
The window slide bars can be fixed with the clear plastic bolt. Fig. 4.

BEFORE USING YOUR APPLIANCE
SWITCHING ON/OFF THE AIR CONDITIONER
The appliance can be switched ON or OFF by pressing the POWER button on the control panel or the ON/OFF button on the remote control
COOLING MODE
In this mode, the air conditioner cools and dehumidifies the room. To activate this function mode, press the MODE button until the COOL indicator light comes on. When the cooling mode is set, the compressor will start in approximately 3 minutes. 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 of this air conditioner is from 62°F / 17°C to 88°F / 30°C. To set the temperature, press the + or - buttons. This air conditioner has a 5°F temperature cushion which if the set temperature is within 5°F of the ambient temperature, the unit runs on fan only mode. This saves energy and prolongs the life of the compressor of the air conditioner.
To set the fan speed, press the FAN 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.
A dual hose portable air conditioner may cool a room faster and will help minimize a negative air pressure situation in the room. If the outside temperature is much higher or more humid than the room, the intake hose can be disconnected and it will function like a single hose unit.
DRY (DEHUMIDIFYING) ONLY MODE
In this mode, the air conditioner only dehumidifies the room, the compressor will activate intermittently depending on the ambient temperature and the fan speed is set to LOW. To activate this function mode, press the MODE button until the DRY indicator light is displayed. Please note that when switching function mode, there will be an approximately 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. Also, the air conditioner does not have a humidistat in which a specific humidity level can be set.
AUTOMATIC MODE
When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending on the temperature of the room. The fan speed is automatically selected and cannot be changed. To operate the unit in Auto mode when the unit is on, press the MODE button until the AUTO indicator light comes on.
FAN ONLY MODE
In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode, press the MODE button until the FAN indicator light comes on. In this function mode, the temperature cannot be set. Subsequently, set the desired fan speed by pressing the FAN button. Fan Only mode does not require the use of both exhaust and intake hoses.
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.
SETTING SWITCH OFF TIMER
With the air conditioner operating in any function mode, press the TIMER button. The TIMER OFF light will come on. Then set the desired time delay OFF hours by pressing the UP and DOW N buttons. The time increments are at 0.5 hour to up to 10 hours, followed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches off. To cancel the delayed switch off function, turn off the air conditioner or adjust the time setting to 0.0.
SETTING DELAYED SWITCH ON TIMER
With the air conditioner is off, press the TIMER button. The TIMER ON light will come on. Then set the desired time delay ON hours by pressing the UP and DOW N buttons. The time increments are at 0.5 hour to up to 10 hours, followed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches on. To cancel the delayed switch on function, turn on the air conditioner or adjust the time setting to 0.0.
SLEEP MODE
In this mode, the air conditioner gradually increases the set temperature in cooling mode, decreases the noise level and conserves energy. In Sleep and cooling mode, the set temperature is increased by 1°C/ 2°F in the first 30 minutes. The temperature will then increase by another 1°C/ 2°F after an additional 30 minutes. This new temperature will remain the same for 7 hours. To activate this function mode, press the SLEEP button until the SLEEP indicator light comes 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.
CONTROLLING THE AIR FLOW DIRECTION
The louvers can be controlled to Auto-Swing or in a fixed direction. To control the air flow direction by Auto-Swing, press the SWING button. To set the louvers in a fixed angle or direction, press SWING button while on Auto-Swing mode when desired angle is chosen.
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.
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.
SHORTCUT FUNCTION
Push this button when remote controller is on, the system will automatically revert back to the previous settings including operating mode, setting temperature, fan speed level and sleep feature (if activated). If shortcut button is pushed for more than 2 seconds, the system will automatically store the current operation settings including operating mode, setting temperature, fan speed level and sleep feature (if activated).
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.
