3.10. Precautions when Installing a Lift Pipe
•
A lift pipe should be used in situations where a sufficient fall cannot be provided for a standard
condensate drain connection.
•
The installation height of the lift pipe should be less than 850mm. It is recommended to set an
inclination angle 1° - 2° for the lift pipe toward the drainage direction. If the lift pipe and the unit
form a right angle, the height of the lift pipe must be less than 800mm.
