INTRODUCTION / TECHNICAL DATA
HOW IT WORKS
The Whynter compact CFC-free, lead-free, and energy efficient 12,000 BTU portable air condi-
tioner, helps you stay cool while working with better environmental standards and reducing ener-
gy 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.

INSTALLATION
WARNING: NEVER OPERATE THE AIR CONDITIONER WITHOUT THE AIR
FILTER
Your Whynter portable air conditioner is equipped with a wash-
able 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. Fol-
low 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 assem-
bled 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 ARC-
122DS 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 (refer to page 8). This warning light indicates that the water condensation needs to be drained using the fol-
lowing procedures:
• Manual drainage (Fig. 2a)
Carefully move the unit to a drain location, remove the bottom drain plug and let the water drain. Replace the
drain plug and plug in unit to resume operation.
• Continuous drainage (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.
• Heat pump drainage (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 during HEAT Mode. Remove the heat 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. NOTE:
The condensate pump will only engage during Heat mode and will not work in any other modes.

duce 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 but-
ton 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 ap-
proximately 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 com-
pressor 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, do not connect the exhaust hose and let the warm air
return to 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 the Dehumidifying mode, the exhaust and intake hoses should not be vented to the outside. If
the warm air is exhausted to the outside, cooling may occur. Additionally, you must manually drain the water from the
unit.
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.
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 connect-
ed 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.

OPERATION INSTRUCTIONS
 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 en-
vironment. 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) de-
lay can be set, enabled and disabled. The timer is adjustable between 1 - 24 hours.

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
COMPRESSOR LOCK OUT
This portable air conditioner is optimized to operate in an ambient temperature of 64°F – 90°F. The compressor cir-
cuit 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.
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
be collected in the reservoir inside the unit. If the reservoir is full, the compressor will stop. To continue the cooling
function, please drain the water. See page 9.
