Drain Water Treatment
Drain water is discharged during heating and defrosting operation. (Rain water is also discharged.)
Pay attention to the followings.
(1) Choose a place where well drainage is available, or provide a drain ditch.
(2) Do not install the unit over the walkways. Condensation water may fall on people.
In case of installing the unit in such a place, provide the additional drain pan.
(3) When drain piping is necessary for the outdoor unit, use the drain boss set (Optional, DC-01Q).
Do not use drain boss and drain pan kit in the cold area. The drain water in the drain pipe may be
frozen and then the drain pipe may crack.
