CAUTION
•
Make sure to keep the drain hose from getting tangled or loosened (on the connection part).
•
Insulate all condensate pipes connected to the indoor unit to prevent condensation formation.
Condensate formation on condensate pipes can lead to property damage and unsafe environment
conditions.
When passing the drain hose through the hole drilled in the wall, make sure to avoid following cases.
CAUTION
•
Since the draining is of natural drain type, install the drain hose in downward direction.
•
If you do not tie the drain hose with a cable tie, leakage may occur
•
Drain pipe may get clogged if there is any foreign substances within the drain pan, so you must remove
any foreign substances after completing the installation.
