  • Fan ModeHoneywell Portable Air Conditioner - Fan Mode
    For air circulation without air conditioner cooling.
  • Heating ModeHoneywell Portable Air Conditioner - Heater
    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.
    When heating mode is selected the indicator light will shine. In this mode, the desired temperature can be set between 16°C – 32°C (60°F – 90°F).
    Note: The 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.

  • Sleep ModeHoneywell Portable Air Conditioner - Sleep Mode
    When the Sleep Mode is activated in Air Conditioning mode, the set temperature will increase by 1°F or 1°C after the first hour of cooling and will increase a further 1°F or 1°C  after the second hour of cooling. The unit will maintain this temperature for 5 hours. The set temperature will then reduce by 1°F or 1°C on the seventh hour and reduce a  further 1°F or 1°C on the tenth hour. Sleep mode will then deactivate automatically.

In Heating Mode*, the set temperature will reduce by 2°F or 2°C after the first hour of heating and will reduce a further 2°F or 2°C after the second hour of heating. The unit maintains heating at this temperature for 5 hours. Then, the set temperature will increase 2°F or 2°C at the seventh hour and will increase a further 2°F or 2°C on the tenth hour.

When there is excess water condensation inside the unit, the air conditioner stops running and shows a warning light (the WATER FULL indicator illuminates with a red light).  This indicates that the water condensation needs to be drained using the following procedures:

Manual Draining in Cooling, Heating* and Dehumidifying Modes
Water may need to be drained in high humidity areas.

  1. Unplug the unit from the power source.
  2. Place a shallow pan under the lower rubber drain plug.
    See diagram.
  3. Remove the rubber drain plug.
  4. Water will drain out and collect in the shallow pan.
  5. After the water is drained, replace the rubber drain plug.
  6. You can now turn on the unit.

Honeywell Portable Air Conditioner - ModesIf 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:

  1. 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).
  2. 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.
  3. 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 backward back into the air conditioner.Honeywell Portable Air Conditioner - drain

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.

Continuous Draining for Dehumidifier Mode While using the unit in dehumidifier mode, continuous drainage is recommended.

  1. Unplug the unit from power source.
  2. Remove the upper/ lower rubber drain plug.
    Some residual water may spill so please have a pan to collect the water.
  3. Connect the drain tube (included) to the upper or lower drain (whichever is more convenient for your space).
    See diagram.
  4. The water can be continuously drained through the drain tube into a floor drain or bucket.
  5. Replace the drain plug.
  6. You can now turn on the unit.
    Honeywell Portable Air Conditioner - Dehumidifier Mode

IMPORTANT: It is NOT recommended to connect the drain hose for continuous drainage while the unit is switched ON in air conditioning cooling mode. Doing so can reduce the cooling efficiency of the Portable Air Conditioner. Only drain the water condensation when the unit is switched off. Continuous drainage is only suitable when the unit is set up in Dehumidifier mode.

IMPORTANT: The water cannot be drained using the continuous drain option in heating* mode. In Heating mode, the internal water tank collects condensation faster and may require more frequent emptying of the tank in more humid rooms. It is recommended to use the heating mode in a room with 50 % humidity or lower. Avoid operating moisture-creating products or appliances such as a humidifier or a kettle when using the unit in heating mode.


The following troubleshooting guide addresses the most common problems. If problems persist, call customer support. Unplug and disconnect the appliance from the power source before attempting to troubleshoot.

Can I use the unit in a window?

No, the unit is not designed for use in a window.

Can I use the unit in an RV?

Yes, the unit can be used in an RV. However, you need to ensure that the power cord is long enough to reach an outside outlet.

Is it OK to use extension cords with this unit?

Yes, you can use extension cords with this unit. However, you need to ensure that the cord is rated for outdoor use and is grounded. You should also make sure that it is UL listed and has a 3-prong plug.

How do I clean my portable air conditioner?

You should take care of your portable air conditioner by cleaning it regularly. To clean your portable air conditioner, unplug it from the power source and wipe it down with a soft cloth. If there are any hard-to-reach areas, you can remove the front grille and wipe those areas down as well. You should also clean your filter once every month or so (depending on how often you use your portable air conditioner). To do this, unplug your portable air conditioner from its power source and remove the front grille. Then, remove your filter and replace it with a new one. Finally, plug your portable air conditioner back into its power source and turn it on as normal.

What are some of the ways I can lower my energy costs when using my portable air conditioner?

You can lower your energy costs when using your portable air conditioner by keeping your home’s doors and windows closed while you’re using it. This will help keep cool air inside of your home instead of letting it escape outside of your home through open doors and windows. You can also lower your energy costs by setting your portable air conditioner to run on low instead of high when cooling down a room or area of your home that’s already cool or comfortable (like an empty bedroom). Another way to lower your energy costs is to set up a programmable thermostat that allows you to set different temperatures for different times of day (for example, you could have the temperature set at 75 degrees during the day and at 70 degrees at night). This will allow you to save money on energy costs because you won’t have to run your portable air conditioner as often if you’re only cooling down rooms that are already cool or comfortable (like an empty bedroom).

How do I reset my Honeywell portable air conditioner?

Switch the Portable Air Conditioner OFF and carefully remove filters from the unit and clean. Replace filters and press the Filter Reset button, the Filter Reset light will turn off and the operation time will be cleared.

Why is my Honeywell air conditioner not working?

Your Honeywell thermostat may fail to turn your AC on at times. The easiest way to fix it is to reset your thermostat. Other common methods include replacing your batteries, checking your wiring, and cleaning the air filter associated with your Honeywell Thermostat.

Why does my portable AC keep filling up with water?

The unit is designed to collect the moisture from the air in the room. If the room has a high humidity level, the unit will work harder to cool the air thus collecting more water.

Why is my Honeywell portable air conditioner leaking water?

A loose drain cap or plug won’t hold water in, and will start to leak out water from your unit as it cannot sufficiently keep your AC unit water tight. Check your drain cap for any drips, and tighten or fasten the plug as much as you can to keep it from leaking water out of your portable air conditioning units.

What is wrong with my portable air conditioner?

The most common cause of a portable AC not cooling a room is lack of adequate airflow. If the air filter is dirty or clogged, there may not be enough air flowing over the evaporator coils and the coils can become too cold and frost over. This restricts airflow and a portable AC won’t cool the room.

Why does my air conditioner turns off after about 15 minutes?

If there’s something wrong with your air conditioner that makes it shut off after just 15 minutes, it’s usually one of these issues: Unit is overheating: This often means there is simply a buildup of grime inside the compressor unit, but it could also mean there’s a refrigerant leak or another problem.

How do I know if my AC coil is dirty?

3 Warning Signs of Dirty Evaporator Coils
Poor cooling. If your home doesn’t feel cool enough no matter how long the air conditioner has been running, this is one of the most noticeable signs that your evaporator coil is dirty.
Frozen coil.
Longer AC runtimes.
