II. Pipe Installation for the Condensate Water
System
1. Pipes
Generally, U-PVC water supply pipes bonded with special glue are adopted as condensate water
pipes. PP-R, PP-C, and hot galvanized steel pipes can also be adopted. Aluminium plastic compound
pipes cannot be used.
2. Requirements on Installation
2.1 Determine the direction and elevation of a condensate water pipe before installing it. Avoid
overlapping it with other pipes to ensure straight inclination. The clamp of the pipe hanger is fixed
outside the insulation layer. The height of the clamp can be adjusted.
2.2 Distance between Hangers

There are at least two hangers for each vertical pipe.
2.3 The inclination degree of the condensate water pipe must be above 1% and that of the main pipe
cannot be lower than 0.3%. Adverse slopes are not allowed.
2.4 When connecting three-way pipes, the two-way straight pipes must be laid on the same slope, as
shown in the following figures.
2.5 The condensate water pipe cannot be tied with the refrigerant pipe.
2.6 A ventilation hole must be provided on the top of the drain pipe to ensure smoother discharge of
condensate water.
