THANK YOU
USER TIPS
Congratulations on your purchase of this Honeywell Portable Air Conditioner.
Regarding the information pertaining to the installation, handling, servicing, cleaning and disposal
of the appliance, please refer to the below paragraph of the manual.
Portable Air Conditioners are ideal for spot cooling. The compressor, condenser and evaporator are
housed in a compact unit. The air is dehumidified and cooled while a flexible Exhaust Hose sends
heat outside. The air conditioner includes a window venting kit.
No permanent installation is needed. The unit is easy to move from room to room and offers a truly
flexible air conditioning solution.
Auto Evaporation System - The unit automatically evaporates the condensate through the Exhaust
Hose. There is no need to empty the drainage tank except in humid conditions. Read and follow the
instructions carefully.
To ensure optimal efficiency of the product, keep doors and windows closed when it is used as an air
conditioner or dehumidifier. If the product is being used with the fan function only, an open window
could improve air circulation.
EN
Important:
Before installing the unit, place it UPRIGHT for 1 hour before use to allow the refrigerant to stabilize.
Manually adjust the air vent located at the top of the unit to adjust the direction of air flow.
Follow installation instructions to set up the unit.
Plug the unit into a properly grounded circuit. DO NOT plug into an extension cord.

Note: After setting the window bracket to the size of your window, please remove it from the window
and follow the instructions below.
To install the window bracket to the window frame, you need to adjust the height or width of the
window bracket by extending the length according to the height or width of the window. When the
length is set, tighten the Adjustable Knobs (preinstalled on the window bracket) to ensure the window
bracket is secured in the desired position. Use one or all three pieces of window bracket as needed.

INSTALLATION (CONTINUED)
4. Connect the window bracket to the window bracket panel adapter. Slide-in the window bracket
panel adapter then rotate clockwise until it is locked in place.
5. Connect the window bracket to the window.
6. The Portable Air Conditioner is now ready to use.

INSTALLATION (CONTINUED)
IMPORTANT: Do not replace or lengthen the Exhaust Hose as this could cause the unit to
malfunction.
The supplied Exhaust Hose has a diameter of 5" (12.7 cm) and can be extended from
12" to 47" (30 cm to 120 cm).
Do not bend (to the extent shown below) the Exhaust Hose. A bent hose will block exhaust air and
cause the unit to malfunction or shut-off.
Make sure the back of the unit is at least 31.5" (80 cm) away from the wall and the minimum air
space from top / front / left / right is 20" (50cm). Do not place the unit in front of curtains or
drapes as this could obstruct the airflow.

WARNING: Any warranties included with this product will be voided if an extra extension hose is
added to the originally provided installation kit or if the installation is performed differently than the
manufacturer's instructions, without proper consultation. Please contact Customer Support for help

USE & OPERATION (CONTINUED)
EN
Heating Mode*
This unit uses HeatPump technology which reverses the air conditioning cooling cycle by
transferring heat from the outside into the room – this is more energy efficient than traditional
electric heaters that generate heat instead of transferring heat into the room. These properties
make this heater ideal for use in autumn or spring when outdoor temperatures are not severely
cold, or as supplemental heating in colder rooms of your home.
•
Fan Mode
For air circulation without air conditioner cooling.
•
Dehumidifying Mode
Air is dehumidified as it passes through the unit, without being in full cooling mode.
If room temperature is higher than 25°C (77°F) fan speed can be adjusted; otherwise fan speed is
preset to LOW.
Note: If the unit will be used mainly as a dehumidifier, do not connect the Exhaust Hoses.
Continuous drainage is then necessary (refer to Continuous Draining for Dehumidifier Mode).
•
When heating mode is selected the indicator light will shine. Heating is activated only when
the ambient temperature is below 25°C (77°F). In this mode, the desired temperature can be
set between 16°C 25°C (61°F - 77°F).
Note: The Exhaust Hoses must vent outside the room when using heating mode.
IMPORTANT: The Heat pump draws moisture from the air which then condenses into the
internal water tank. The unit will pause operation when the tank is full and will restart when
the tank has been emptied. It is recommended to use the heating mode in a room with 50%
humidity or lower. Avoid operating moisture-producing products or appliances such as a
humidifier or a kettle when using the unit in heating mode.
See the "Draining Water Condensation in Heat Mode" section for more information on
draining the water tank.
FUNCTION BUTTONS (CONTINUED)
IMPORTANT: The Dehumidifier mode is used to support moisture reduction but should not
be expected to dehumidify to the same degree as a standard dehumidifier-only appliance. The
built-in dehumidifier automatically adjusts dehumidification based on ambient room temperatures.
It is not possible to adjust to a desired humidity percentage. The front display only shows the
current AND desired temperatures. It does not show humidity levels.

Manual Draining in Cooling, Dehumidifying and Heating* Modes
Water may need to be drained in high humidity areas.
If you find that there is a high volume of condensation and a shallow pan is not enough for your use,
you can use a large pan to drain. Follow the below instructions carefully:
WARNING: For safety reasons, the Portable Air Conditioner must NOT be positioned on a base that is
higher than 1" from the floor. This is only recommended if you have a stable, flat base to position the
Portable Air Conditioner on safely.
Find a flat, stable board that is up to 1" thick. The base
could be a wooden board purchased from your local
hardware store, with a minimum base dimension of 20"
(length) x 17" (width) x 1" (thick).
The base should be large and sturdy enough to fit the
Portable Air Conditioner on top. The air conditioner must
be stable and not rock or move when positioned on this
base and not easy to topple over.
Drain the water from the lower drain plug as needed,
into a larger pan or through a drain tube. If using a drain
tube, you can purchase vinyl tubing which has an outside
diameter of 5/8" and an inside diameter of ½".
Remember the drain tube must be positioned lower than
the drain plug so the water condensation does not
flow backwards back into the air conditioner.
