Installation Preparation
Before you begin, make sure that you have all the parts necessary for installation and that you
have selected a suitable location.
Location
When choosing a location, please keep in mind:
 The air conditioner should be placed on a firm, level location in order to minimize noise and
vibration. Your appliance has casters to aid in placement. Use caution when rolling on
carpet and do not attempt to roll the unit over any objects as this may result in the unit
tipping over.
 Never place any obstacles around the air inlet or outlet of the unit.
 Allow at least 20” of space from the wall for efficient performance.
Window Slider Kit Preparation
 Your window slider kit has been designed to fit most standard vertical and horizontal window
applications
 If the window opening is less than the minimum length of the window slider kit, you may trim
the slider panel B. (trim side farthest from exhaust port).
 Slide Panel A inside panel B and adjust to correct width. To secure the panels together, press
the Window Slider Kit ‘Bolt’ into the appropriate slot on the edge of Panel A.

Installation in a Double Hung Sash Window
Step 1: Cut the foam seal to the proper length and attach it to the window sill, and window frame
as shown in the image to the left. Your window kit includes four (4) adhesive backed foam strips
for this step, two that are short and two that are longer.
Step 2: Attach the window slider kit to the window sill. Adjust the length of the window slider kit
according to the width of the window. Use the winder slider “bolt” to secure the slider to the correct
width. Open the window sash and place the window slider kit on the window sill then close the
window sash securely against window slider kit.
Step 3: Cut the foam seal to an appropriate length and seal the open gap between the top window
sash and outer window sash.
Note: If desired, you may choose to attach the adhesive foam seal to the window slider kit instead
of the window sill and frame.
Note: If needed, you may trim the adjustable window kit if the width of the window is less than
26 1/2.”

6
Step 4: If desired, secure the security bracket to the window frame. When installed properly, the
bracket will prevent the window sash from being opened.
Installation in a Sliding Sash Window

the flexible exhaust hose so that you can thread the adapter into place. Rotate the adapter until it
is tightened securely. Repeat this process for Hose Adapter (c) and tighten securely.

8
Step 2: Place unit in location
Roll the unit towards the location where the window kit has been installed. Please ensure that the
unit is at least 20 inches from the wall to ensure proper ventilation.
Step 3: Connect Exhaust Hose to unit
Align the hooks on the Hose Adapter (c) to the Exhaust Air Outlet on the back of the unit. Slide the
hose downward and into place.
Step 4: Connect Exhaust Hose to the window kit.
Push the Window Exhaust Adapter which has been attached to the Exhaust Hose through the
window kit hole and rotate until secure.
After you have installed the exhaust hose and window kit, you can plug in your portable air
conditioner and power on.

9
Do not lengthen the
exhaust hose by adding
additional hoses or
attachments.
Notes About the Exhaust Hose
Your portable air conditioner is designed to exhaust condensate water that is collected from the
air. This water, in either gaseous or droplet form, will be expelled out of the exhaust port of the
unit. Please take this into account when deciding how to vent it.
1. The exhaust hose supplied with the portable air conditioner can be extended up to
approximately 48 inches. However for maximum efficiency, use the shortest length possible.
2. Try to prevent any kinks or bends in the exhaust hose. Kinks or bends may trap exhaust
air which can radiate heat into the room or potentially cause the portable air conditioner to
overheat and shut itself off.
3. The exhaust hose supplied with the portable air conditioner has been specifically designed
for this air conditioner. Do not lengthen the hose by adding additional hoses or attachments.
Do not replace it with any other hose.
The exhaust hose must be installed in accordance with the usage modes:
A. You must install the exhaust hose if the unit is in Cooling Mode.
B. In Dehumidify Mode and Fan Mode, the unit can operate with or without the exhaust hose
attached. If you choose to operate the unit without the exhaust hose in these modes the
air conditioner will be more portable. However, because the exhaust hose removes hot air
and moisture from the room, more cooling will occur in Dehumidify Mode if the exhaust
hose is attached.
Warning: Longer hoses are not recommended.
Note: The exhaust hose may be compressed or extended according to your installation
requirements. However, it is recommended to keep the exhaust hose length at a minimum.

10
Draining the Unit
When the portable air conditioner is in cooling mode, or dehumidify mode, it will remove moisture
from the air. The condensed water from the air will be collected in an internal reservoir and will be
evaporated and exhausted out of the exhaust hose. However, in very humid conditions, the internal
reservoir may fill completely. This causes the air conditioner to turn off to avoid overflowing the
internal reservoir. The fan will continue to operate.
Continuous Drain
During dehumidifying mode, remove the upper drain plug from the back of the unit. Attach a ¾”
hose that can be locally purchased to the continuous drain outlet. Connect the drain hose adapter
to the end of the hose and place the open end of the adapter directly over the drain area.
Manual Drain
During cooling mode, once the water level of the bottom tray reaches capacity the unit will beep
several times and the digital display on the control panel will read “P1” to indicate the water must be
manually drained. Carefully move the unit to a drain location and remove the bottom drain plug and
connect the drain hose to the drain outlet. The portable air conditioner will now drain through the
drain hose. Please note that this unit has no drain pump; all water will drain with gravity only, i.e.,
only “downhill.”
Once the unit is fully drained reinstall the bottom drain plug and restart the machine until the “P1”
symbol disappears. If the error repeats call for service.
