Water leaking from
indoor unit into the room.
Water leakage in
outdoor unit.

CAUSE/SOLUTION
Cause: There are a number of possible reasons.
Solution: Check the following:
• The batteries might be low. Change the batteries.
• The remote controller must be within 25 ft. (7.6 m) with no obstructions of the
indoor unit. If remote controller is lost or damaged and needs to be replaced,
contact your qualified service professional for assistance. In the meantime,
use the manual override mode to operate the system.
Cause: While it is normal for the system to generate condensate water in cooling mode,
it is designed to drain this water to the outdoors via a condensate drain tube.
If water is leaking into the room, it may indicate one of the following.
Solution: • The indoor unit is not level right to left. Level indoor unit.
• The condensate drain tube is restricted or plugged. All restrictions must be
removed to allow continuous gravity force drainage.
• If problem persists, contact a qualified service professional for assistance.
Cause: It is normal for outdoor unit to generate condensate water in reverse cycle
heating mode and defrost.
Solution: This is normal. No action is required.
Cause: There are a number of system functions that will prevent the indoor fan from running.
Solution: Check for the following:
• In heating mode, the indoor fan may not start for three minutes if the room
temperature is very low to prevent blowing cold air.
• I n heat mode, if the outdoor temperature is low and humidity is high, the system
may need to defrost for up to 12 minutes before beginning a heating cycle.
• In dry mode, the indoor fan may stop for up to three minutes during the
compressor off delay.
• Otherwise, you should contact a qualified service professional for assistance.
Cause: It is normal for the system to develop condensation or moisture on the
discharge air louvers when cooling warm humid air for a long period of time.
Solution: The condensation or moisture will disappear as the system cools and
dehumidifies the room space.
• Water is leaking in the room
• Liquid is spilled into unit
