•
If the extension
drain hose has to pass through a room, be sure to wrap it with in-
sulation
(field-supplied).
• The drain hose should point downward for easy drain. (Fig. 1)
•
If the drain hose provided with the indoor unit is too short, connect it with a field-
supplied drain hose (I). (Fig. 2)
• When connecting
the drain hose to a hard vinyl chloride pipe, be sure to insert it
securely into the pipe. (Fig. 3)
