gradient smooth and straight, avoid intersecting with other pipelines. The height of the
clamp fixing the pipe hanger frame shall be adjustable and fixed from the outer of thermal
insulation.
3).Distance between hanger frames:

Each standpipe shall have two hanger frames at least.
4). The gradient of condensate pipe shall be over 1% and the gradient of main pipe shall not
be less than 0.3%, while there shall be no overhanging slope.
5). When connecting the 3-way section of condensate pipe, the 2-way straight section on
3-way pipe shall be on the same gradient. The two ends of 2-way section shall not have different
gradient. See the schematics below:

6). Confluence toward the horizontal pipe shall be best from the upper. Back flow is easy to
occur if from the lengthwise direction.
7Do not tie the condensate pipe and refrigerant pipe together.
8) To ensure smooth drainage of condensate, a vent hole shall be set at the highest point of
drainage pipe.
9) Carry out water flow test and full water test after the pipe connection is completed. On one
hand, check if the drainage is smooth; on another hand, check the piping system for any
leakage.
