INTRODUCTION / TECHNICAL DATA

Please follow the instructions provided in this user guide to obtain the very best performance from your portable air conditioner and take full advantage of the many features your portable air conditioner offers you. We trust that your Whynter air conditioner will provide the performance and reliability that we stand for. Please keep this user manual in a safe place for future reference.

HOW IT WORKS
The Whynter compact CFC-free, lead-free, and energy efficient 12,000 BTU portable air conditioner, helps you stay cool while working with better environmental standards and reducing energy consumption.
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-122DHP 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 will cool a room faster and will help minimize 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 l function as a single hose unit.

NEVER OPERATE THE AIR CONDITIONER WITHOUT THE AIR FILTER
Your Whynter portable air conditioner is equipped with a washable Pre-Filter and an Activated Carbon Filter.
The washable Pre-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. Follow the steps below to install the filters.

1. Pull up the pre-filter frame (Fig. 1a)
   
2. Place the activated carbon filter on the pre-filter frame by inserting it through the three pins (Fig. 1b)
   
3. Once the activated carbon filter is secured, insert the assembled filter frame into the unit.

WATER DRAINAGE
The dehumidifying capacity of this unit is 76 pints per day. The patented self-evaporating function of the ARC122DS 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 shows a warning light. This warning light indicates that the water condensation needs to be drained using the following procedures:

• Manual drainage (Fig. 2a)
  Turn off the unit. Carefully roll the unit to a drain location or position a flat container, dish or optional drain bucket accessory (sold separately) under the drain area of the lower drain port. Remove the drain cover and rubber plug and the condensed water will drain out automatically. Once all the condensed water is drained, replace the drain rubber plug and cover into the drain firmly.
  
• Continuous Gravity drainage option (Fig. 2b)
  Remove the upper drain plug from the back of the unit and install the drain hose (sold separately). Place the open end of the hose to a drain area. This method is recommended if uninterrupted operation is desired.
  
• Auto Pump drainage option (Fig. 2c)
  This unit has a condensate pump feature that can pump out (and up) water through the included drain hose for continuous water removal. Remove the pump drain plug from the back of the unit and install the drain hose. Place the open end of the hose to a drain area.

Location
The air conditioner should be placed on a hard and level surface strong enough to support its weight. The unit is equipped with caster wheels for portability. 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.
The air inlet and outlet should be free of any obstructions and be placed with at least 20" of clearance for efficient air-conditioning and circulation. Exhaust hose Installation
When using the air conditioner, the hot air from the exhaust hose must be exhausted out of the room to complete the air exchange of the condenser. The intake hose is optional. When the unit is operating in dehumidifying or fanonly mode, installation of the exhaust hose is optional.

1. Expand each end of the exhaust (large) and intake (small) hoses about 6".
2. Install the Large Exhaust Slide Locking Hose Connector to one end of the exhaust hose (large hose) and the Large Exhaust Hose Connector with tab cut-outs to the other end of the exhaust hose (large hose) by turning counterclockwise.
3. Install the Small Intake Slide Locking Hose Connector to one end of the intake hose (small hose) and the Small Intake Hose Connector with tab cut-outs to the other end of the intake hose (small hose) by turning clockwise.
4. Slide each of the slide locking hose connectors onto the rear of the unit (See illustration)

Only extend the hose to the necessary length, keeping it as short and as straight as possible. We do not recommend extending the hose more than 9' long. If you are interested in purchasing an additional 5' exhaust hose, please contact support@whynter.com for retail sales information or visit whynter.com for a list of optional accessories.
Note: To remove the hose(s) from the unit, press the release button and slide the hose and connector out.

Window kit Installation
Your window kit has been designed to fit most standard vertical and horizontal windows. However, it may be necessary for you to modify the installation procedures for your window.

NOTE:
If your window opening is smaller than the minimum length of the window slider kit, the window slider kit can be cut to fit the window opening. Never cut into the exhaust and 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.
When using the window slider kit on a window or sliding door, additional security measures may be needed.

1. Open the window approximately 5".
2. Adjust the length of the window slider to the same length and width of the opening of the window. Cut the window slider if necessary to fit the length of your window.
3. Insert the fixture through the back grooved side of the window slider hose cut-out. Line up the fixture with the 4 screw holes and tighten the fixture with 4 screws from the front side of the slider panel. (Fig. 1)
   
4. Fit the window slider kit into the window opening and close the window to secure the window slider kit. For long term installation, you may screw the window kit into your window frame.
5. Move the air conditioner close to the window, extend the hoses to the necessary length, keeping them as short and as straight as possible and attach the other end of each hose to the window slider kit.
6. Align the tab cut-outs of the hose connectors to the tabs on the fixtures and snap the hose connectors to the window slider kit.

OPERATION INSTRUCTIONS

BEFORE USING YOUR APPLIANCE

• Remove the exterior and interior packing
• Before connecting the appliance to the power source, let it stand upright for approximately 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 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 Control until the Cooling 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 61°F / 16°C to 89°F / 32°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 will cool a room faster and will help minimize 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 covered with the included cover and it will function like a single hose unit.

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 Control until the Dehumidifying indicator light comes on. Please note that when switching function mode, there will be an approximately 3 minute transition time. In dehumidifying mode, the exhaust hose is optional and the intake should not be vented. If the exhaust is vented, warm air is exhausted to the outside and cooling may occur. If cooling is not preferred, remove the exhaust hose and allow the warm air from the back to return to the room to avoid cooling. 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. 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 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 exhaust and intake hoses.

HEAT MODE
In this mode, the air conditioner heats the room. To activate this function mode, press the Mode Control button until the HEAT indicator comes on. When the heating mode is set, the compressor will start in approximately 3-5 minutes.
NOTE: In heating mode, cold air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the cold air. If outside temperature is lower than inside temperature, air intake hose should be blocked and unit will take in air from the air filter.

• The temperature setting range of this air conditioner is from 61F to 77F. To set the temperature, press the + or – buttons. Once the set temperature is achieved, the compressor and the fan will stop
  NOTE: This unit uses heat pump from heating and the heating mode does not work when temperature is below 45F.
• To set the fan speed, press the Fan Speed button. In Heating 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.
• Please note that in Heat mode, the unit may need to be drained more often as the self evaporating function is not applicable in this mode.

HEAT PUMP FUNCTION
In Heating mode, the heat pump reverses the cooling sequence and produces heat instead of cooling the indoor environment. The evaporator coil switches function and becomes the condenser coil. The condenser also switches roles to serve as the evaporator, and discharges cold air.

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

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

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.

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
