Installing the Carbon Filter
Your portable air conditioner ships with a pre-filter and an activated carbon filter. The carbon filter
will help remove contaminates and odors from the air. It is recommended you replace the carbon
filter every three to six months, or as needed. It is necessary to clean the pre-filter periodically.

1. Pull the handle on the pre-filter straight up.
2. Separate the filter frame from the pre-filter.
3. Place the activated carbon filter on the pre-filter.
4. Reattach the filter frame.
5. Insert the assembled pre-filter into the back of the unit.
Caution: Never operate the air conditioner without the pre-filter attached.

Window Kit Installation Instructions
Preparations for Installing the Window Kit
You must vent your portable air conditioner when running it in cooling mode. Your unit includes a
window exhaust kit that can be used to vent the unit out of a window.
Before you begin, make sure you have all the parts necessary for installation.
Window Kit Parts list:
If you have multiple windows, choose one that is near an electrical outlet that will be able to
provide sufficient power to your unit. See the power requirements listed on the product label
printed on the side, or on the back of your portable air conditioner.
Your window kit can be installed on a horizontal or vertical sliding window as shown in the
following images:
Follow the instructions on the next pages to install the window kit.
Note: You may need to contact your electrician if your room’s circuit is not able to power your
unit.

5
Installing the Grated Adapter
1. Insert the round grated adapter through the back grooved side of the window kit plate into the
hole.
2. Secure the grated adapter by fastening the screws from the flat side of the window kit plate to
the holes on the grated adapter.

6
Installing the Window Plates
3. Open your window and place the window kit on the window sill with the grooved side facing
outward. Then slide the window kit plate out to fit the width of the window. You can use
screws to secure the window kit plate and keep it from sliding.
4. Lower the window to secure the window kit in place. You may need to use duct tape to better
secure the window kit.
Caution: Secure your window with window locks. Please contact your dealer to purchase window
locks.

7
Attaching the Duct Connectors to the Exhaust Hose
5. Attach the connectors to the hose:
A. Extend the ends of the exhaust hose
B. Thread the duct connector on by turning it clockwise until it stops.
6. Roll the unit towards the window kit. Leave at least 20 inches between the unit and the wall.
Connecting the Duct Connector to the Unit
7. Align the slots on the duct connector to the tabs and snap it into the back of the unit.

8
Connecting the Duct Connector to the Grated Adapter
8. Align the slots on the duct connector to the tabs on the grated adapter and snap the duct
connector into place.
After you have installed the exhaust hose and the window kit, you can plug in your portable air
conditioner and start using it.
Control Panel Overview

9
Using the Control Panel
Power:
Use the Power button to turn the portable air conditioner on and off.
By default when you first use the power button, the unit will begin to operate in cooling mode.
The unit will remember the last used mode / settings if you shut it down and restart it.
Auto-Restart: If power to the unit is interrupted, the air conditioner will restart itself in its last
used mode / settings once power is restored. The compressor will restart after three (3)
minutes.
Cooling Mode:
Cooling mode cools and dehumidifies the air. If the ambient temperature drops below the
temperature you selected, the compressor turns off and the unit functions with the fan only.
When the temperature rises above the temperature you selected, the compressor turns on
again.
To operate the unit in cooling mode:
1. Make sure the power cord is plugged into a power outlet.
2. Press the Power button.
3. Press the Mode button until the LED indicator next to “Cooling” lights up.
4. Select the fan speed by using the Speed button.
5. Set the thermostat by using the Up and Down buttons. The thermostat is adjustable
between 61°F - 89°F in one degree increments.

10
Dehumidifying Mode:
During the Dehumidifying mode, the unit will condense water out of the air and exhaust it
through the exhaust hose. The ambient temperature in the room will probably drop by a few
degrees while using the Dehumidifying mode.
To operate the unit in dehumidifying mode:
1. Make sure the power cord is plugged into a power outlet.
2. Press the Power button.
3. Press the Mode button until the LED indicator next to “Dehumidify” lights up.
Heat Mode:
Your air conditioner can work as a heat pump. It must be vented so that it can expel the cold
air out of the exhaust.
To operate the unit in heat mode:
1. Make sure the power cord is plugged into a power outlet.
2. Press the Power button.
3. Press the Mode button until the LED indicator next to “Fan” lights up red.
Fan Only Mode
Fan Only mode is used to circulate the air in your room. No temperature setting is needed.
To operate the unit in Fan Only mode:
1. Make sure the power cord is plugged into a power outlet.
2. Press the Power button.
3. Press the Mode button until the LED indicator next to “Fan Only” lights up.

Medium, or Low settings will light up.
Note: Fan Only mode does not require that the exhaust hose be attached.
Notes: If the room temperature is below 77° F, the fan will always run on low speed while in the
Dehumidifying mode. If you do not use the exhaust hose in Dehumidifying mode, you must
manually drain the water from the unit. Additionally, the ambient temperature in the room will
probably rise by a few degrees if you do not use the exhaust hose. You will not be able to change
the thermostat temperature while in Dehumidifying Mode.

Energy Saving Guide
Read and follow the guide below to get the best performance and efficiency from your portable
air conditioner:
Do not cover the air outlet (exhaust) while the unit is in use.
Do not place the unit in front of curtains or drapes as they may obstruct the air intake.
Minimize the length of the exhaust hose.
Make sure the exhaust hose is as straight as possible and avoid kinks or bends.
Keep curtains, blinds, or drapes closed during the sunniest part of the day.
Use the timer to operate the unit before it is needed. For example, set the timer to turn the
unit on in cooling mode for 3 or more hours to cool the room before you arrive. You may want
to operate the unit all day if you live in a warmer climate.
Minimize the heat sources (direct sunlight, computers, servers, people, etc.) in the room.
Close all windows and doors.
Use the unit in a contained room. For example, a room with four walls and a ceiling, instead of
a partitioned studio, or warehouse.
Make sure the unit is on a level surface.
Minimize the amount of humidity in the room. For example, run the unit as a dehumidifier.
To prolong the compressor's life, please wait at least 3 minutes before turning the unit back
on after shutting it off.
Inspect and clean the pre-filters regularly.
Inspect and replace the activated carbon filters regularly.
Perform routine maintenance.
Caution: Use only AAA batteries. Remove the batteries if the remote control will not be used for
one month or longer. Do not attempt to recharge batteries that are not designed to be recharged.
All batteries should be replaced at the same time. Do not mix old and new batteries. Do not
dispose of batteries in a fire as they may explode.
