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 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 DEHUMIDIFYING or FAN only
mode, no exhaust is required.
1. Pull out about 6” of one end of the hoses.
2. Attach the hose connectors to the hoses by turning clockwise.
3. Align the slots on the hose connector to the tabs on the air intake / outlet and snap the
hose to the unit.
EXHAUST
INTAKE
4. Only extend the exhaust hoses to the necessary length. We do not recommend
extending the exhaust hose more than 9' long. Additional 4’ exhaust hose sold
separately.
* If you are interested in purchasing optional accessories, please contact
info@whynter.com for retail sales information.

Window kit 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 dehumidifying and fan-only
mode, no exhaust is required.
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 less than the mentioned minimum length of the window slider
kit, cut the slide bar with hole to fit window opening. Never cut out the hole on the window slide
bar.
NOTE: W hen using the window kit on a window or sliding door it will cause the
window or sliding door not to be properly closed and locked. Additional security
measurements may be needed.
1. Open window approximately 5”.
2. Adjust the length of the window bars to the same length and width of the opening of the window.
Cut the window piece if necessary to fit the length of your window.
3. Insert the fixtures through the back grooved side of the
window slide bar with holes. Line
up the 4 holes and tighten the fixtures with 4 screws from
the front. Fig 1.
4. Close the window on the window slide bars. For long
term installation, you may screw the window kit into your
window frame.
5. Move the unit to the window, extend the hoses and
attach the other end of the hoses to the window slide
bar.
6. Align the slots on the hose connectors to the tabs on
the fixtures and snap the hoses to the window slide
bar.

designed to do the following.

Open channel structure provides optimal airflow efficiency.

Antimicrobial agent helps inhibit the growth of mold and mildew.

Micro-structured and electrostatically charged media traps and retains particles.
WARNING: NEVER OPERATE THE AIR CONDITIONER WITHOUT THE PRE-FILTER

OPERATION INSTRUCTIONS
 BEFORE USING YOUR PORTABLE AIR CONDITIONER
 Remove the exterior and interior packaging.
 Before connecting the unit 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 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 this function
mode, press the Mode Control button until the
indicator comes on. When the 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 of this air conditioner is from 61°F to 89°F. 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. Once the set temperature is achieved, the fan runs continuously.
 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 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 button until the
indicator 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 air exhaust hose 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 Control button until the
indicator comes
on. In this function mode, the temperature cannot be set. Subsequently, set the desired
fan speed by pressing the Fan Speed button. Fan Only mode requires that the exhaust
hose be removed.
NOTE: The unit does not need to be vented in Fan Only mode.
12 | P a g e
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 SW ITCH 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. W hen 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. W hen 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.
1.
Turn off the unit.
2.
Position a flat container or dish under the drain plug.
3.
Remove the drain plug and the condensed water will drain out automatically.
4.
Once all the condensed water is drained, replace the drain plug into the drain firmly.
13 | P a g e
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.
INSTALLING BATTERIES
 Only use two AAA 1.5V Batteries in the remote control.
 Always change both batteries at the same time.
To insert the batteries, open the flap on the back of the remote control by sliding if off. Strictly
adhere to the polarity signs on the bottom of the battery housing, close the flap once the batteries
have been inserted.
