•
bottom plate;
The condensate pipe should be as short as possible drains in run-off elevation (under way), avoid
•
the drainage pipe up and down, and prevent counter fl ow of the condensate water;
A 1/100 or more gradient should be provided for installation of the horizontal drainage pipe.
•
Moreover, the hose should be fi xed with suspension rods, and the distance between them is 1.0
to 1.5 m.
Distance between the suspension rods of the horizontal drainage pipe:
