28Figure 9 – Condensate Piping NOTE: Blow water into the condensate collector to remove any foreign matter that may blockthe line.NOTES:1. Condensate line must be pitched at least 1/4" per foot to properly drain. If this cannot be done, or a very long length of condensate hose isused, you must increase the condensate line to a minimum of 1” ID and place a tee in the line after the condensate neutralizer to properlyreduce vacuum lock in the drain line.2. Plastic pipe should be the only material used for the condensate line. Steel, brass, copper, or other materials will be subject to corrosion ordeterioration.3. NEVER install condensate lines outside. It is very important that the condensate line is not exposed to freezing temperatures or any type ofblockage. Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.4. Support of the condensate line may be necessary to avoid blockage of the condensate flow.LP- 429 REV. 6.6.13
