TROUBLESHOOTING GUIDE
Unit leaks water
Possible cause
Solution
Unit is not level
Unit should be level in wall to prevent leaking
Drain line clogged or kinked
Check drain line to make sure water can flow freely
Drain is clogged, preventing water from escaping
1. Disconnect exterior drain line and clear it out; run provided
drain line brush through the drain port and into the interior
drain line.
2. Open access port and, using a flashlight, check drain line
for blockage; drop a pan tab into the drip tray to prevent
further blockages.
Drain line does not have a downward slope
Fix drain line so there is a downward slope from the drain port
to the discharge location
Coil is iced, causing the drip tray to freeze and water to
overflow
Melt ice with blow drier. Soak up water with a towel.
