Indoor Unit Condensate Drain Hose Installation
Refer to the diagrams below and follow proper installation and the position of the drain hose along the refrigerant piping installation path to avoid
leaks. After the drain hose is set in place, always follow with leak / pressure testing and deep evacuation procedures of the refrigerant piping to be
sure all refrigerant piping is properly installed. Re-check and retest as necessary.
• Wall-mounted indoor units have a factory-provided flexible pipe (27/32” O.D./ 5/8” I.D.) to drain condensate water. The flexible pipe connects
to field-provided drain pipe. Use materials that comply with local codes for drain pipe and insulation.
• Remove the drain plug on left or right side depending on the piping installation. Insert the drain hose on the left side when left side piping is
used; install the drain hose on the right side when right side piping is used.
• Drain hose is routed from the indoor unit through the structure (wall) to the outdoor. It must slope at an angle where it is higher at the indoor
unit and lower toward the outdoor area, thereby letting gravity push any condensation down and out.
• The drain hose might need to be extended so that condensate can be properly routed away. Connect the flexible drain pipe with a round
clamp. If the flexible drain pipe is not installed properly, water will leak from the connection.
• Install the flexible drain pipe as straight as possible; sharp angles will cause the pipe to deteriorate and will crack over time.
• Insert the drain hose >2 inches so it won’t pull out of the field-supplied drain pipe.
•
Avoid piping the drain hose as shown in the diagrams in the figure on the next page. These methods are incorrect and can cause leaks
at the indoor unit site.
