- Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up-and-down
slope to prevent reversal flow.
- During drain piping connection, be careful
not to exert extra force on the drain port on
the indoor unit.
- The outside diameter of the drain connection
on the indoor unit is 32 mm.
- Be sure to execute heat insulation on the
drain piping.
- Install the drain raising pipes at a right
angle to the indoor unit and no more than
300 mm from the unit.
