Indoor Unit Condensate Drain Hose Installation

Refer to the diagrams 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.

Indoor units have a choice of drain hose connection locations: left side or right

side. The drain hose must be installed on one of the connection locations, and

depends on indoor unit location, refrigerant piping path, application, and code

requirements.

1. Remove the drain cap from the hole where the drain hose will be connected.

2. Block the unused drain hole with the drain cap. Verify that the cap is tightly

inserted.

3. There are two methods for attaching the drain hose to the indoor unit, depend-

ing on the indoor unit model, the drain hose, and application requirements:

• Type One: Firmly install the drain hose onto the indoor unit drain hose con-

nection.

• Type Two: Firmly install the drain hose onto the indoor unit drain hose connec-

tion, securing the hose with a screw where indicated.

4. Route the drain hose from the indoor unit, through the structure (wall), and to

the outside. 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.
