A small amount of dew can be caused by temperature differences depending on the local weather and is totally normal, as is a small amount of water leakage. To prevent or minimise this, some steps can be taken. Read on to learn how.

If the leakage is severe, a technician's inspection is likely required.

Note: Water may drip from the pipes of the outdoor unit, as condensation could develop when the ambient temperature or humidity changes significantly. This is normal.

Dew is on the Blade or IDU


Causes	Resolutions
The cooling set temperature is low.	Increase the temperature. It is generally recommended to set it to 26°C.
The ambient air humidity is high (continuous inflow of outside air).	Run 'Dry mode' for 3-4 hours, then switch to the Cooling mode (check the inflow of external air/humidity).
The indoor unit fan speed is low.	Set the cooling fan speed to 'Med' or 'High'.
The blade angle is incorrectly adjusted.	Adjust the blade angle. You can adjust the airflow direction up and down with the Vertical air swing button.

Causes of Water Leakage in the Indoor Unit of the AC

There are a number of reasons water leakage may occur in the indoor unit of the AC. The unit may not be levelled and so is causing a flow issue and leakage, the drain hose may be facing above the indoor unit, be bent, or is submerged in water, rainwater may flow through the pipe to the perforated hole, or the drain hole may be clogged.

Check out the tips below to resolve these issues:

1 Use a level to ensure the AC unit is mounted correctly and sitting flat.

2 Check that the drain hose is pointed downward (to prevent reverse flow).

3 Ensure the drain hose is straight and not bent to prevent reverse flow.

The end of the drain hose is NOT to be placed underwater, so check that this isn't the case.

4 Look for damage. If you find damage on the drain hose, reinforce the damaged area with insulation tape.

5 Prevent rainwater from entering by finishing the perforated holes with putty or silicone.

Water Leakage in the Outdoor Unit of the Air Conditioner

In case of water in the outdoor unit piping connection and service valve:

When the air conditioner is operated, the pipe may become cold, and dew may form on the bottom of the pipe connection and the outdoor unit.

This is normal, and is due to the temperature difference with the heat outside.
