• Because the condensed water is gathered in ponding box and is piped out of room. Do not put
anything else in the box.
• Connect the indoor unit first, then the outdoor unit. (TS 4xx)
CAUTION
• Be careful not to let the drain hose slack.
• Heat insulate both of the auxiliary piping.
• Be sure that the drain hose is located at the lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the unit.
