< Condensate Treatment >
Condensate is discharged during heating and defrosting operation. (Rain water is also discharged.)
Note the following.
(1) Choose a place that is well drained or provide a drain ditch.
(2) Do not install the unit over walkways. Condensation may drip on people.
If installing the unit in such a place, provide an additional drain pan.
(3) Do not use a drain adapter in a cold area. The condensate in the drain pipe may freeze resulting in a
cracked pipe.
