CARE AND CLEANING
WATER DRAINAGE
This product has a self-evaporative system. The condensing water will be recycled to cool the condenser. This can not only improve cooling efficiency, but also save energy for you.
Using the Upper Drain Port (Dry Mode Only)
- This can be used when you need dehumidification in high humidity.
- Under the Cool or Fan mode, there’s no need of using the upper drain port.
- During DRY(dehumidifying) mode, remove the drain plug and the exhaust hose from the back of the unit.
- Install a drain hose (12mm [1/2"] inside diameter) and place the open end of the hose at a suitable drain location or outdoors.

Using the Bottom Drain Port
When the internal water collection tank is full , the LED display will show FL and the air conditioner will turn off until the tank is emptied.

- Unplug the air conditioner, disconnect the exhaust hose from the back, and move the air conditioner to a suitable drain location or outdoors. You may also place a pan under the drain that will hold up to 2 pints of water.
- Remove the drain cap from the drain outlet.
- Once the water collection tank is drained, reinstall the drain cap, making sure it is on securely.
- Place the air conditioner in the desired location, reconnect the exhaust hose, and plug in the air conditioner.
CLEANING THE CASE
Wipe the case with a slightly damp cloth, then wipe dry with a dry cloth or towel.

- To prevent damage to the finish, do not use gasoline, benzene, thinner, etc., or any abrasive cleansers to clean the air conditioner; they may damage the finish.
- Never pour water onto or into the air conditioner. It could damage internal components and create a shock and fire hazard.
CLEANING THE AIR FILTER
The air filter should be cleaned every two weeks; depending on indoor air quality, more frequent cleaning may be needed. A dirty air filter will decrease airflow and reduce efficiency.
Do not operate the air conditioner without the air filter in place.

- Pull out the air filter by the handle.
- Use a vacuum cleaner to clean the filter. If the filter is heavily soiled, it can be washed in warm water using a mild detergent. Do not use harsh cleaners or very hot water. Do not wash in a dishwasher.
- Allow the filter to dry completely before reinstalling.
- Reinsert the filter.
STORING THE AIR CONDITIONER
If the air conditioner will not be used for an extened period of time:
- To drain the water collection tank completely, leave the bottom drain cap off long enough to allow any residual water to drain out. Once the tank is completely drained and no more water flows out, reinstall the cap.
- Remove and clean the filter, allow it to dry completely, then reinstall it.
- Remove the batteries from the remote.
- Store the air conditioner in a cool, dry location, away from direct sunlight, extreme temperatures, and excessive dust.
Before using the air conditioner again:
- Make sure the filter and drain cap are in place
- Check the power cord to make sure it is in good condition, with no cracks or damage.
- Place new batteries in the remote.
- Install the air conditioner as described in the Installation Instructions.
