Connect the Drain Hose for Wall-Mounted SystemsUpdated 4 days ago
Introduction
This article explains how to connect the drain hose for wall-mounted systems.
The indoor unit has two drain connections on the left and right sides. Either one can be utilized. One side will have a hose connected, while the other is plugged. 
By default, the drain hose is attached to the left-hand side of the unit (left when facing the back of the unit).
This article is for the following systems:
- Diamante Essenza (WYT-17)
- Diamante Pro (WYT-20)
- Quantum Ultra (WYT-24)
- Quantum Hyperformance (WYT-25)
- Quantum Fresh (WYT-FA)
Steps
Follow these steps to connect the drain hose for wall-mounted systems:
- Attach the drain hose on the same side that the refrigerant piping exits the unit from, ensuring proper drainage.
- Attach any drain hose extensions (sold separately) to the end of the drain hose.
- Wrap the connection point of the drain hose firmly with Teflon tape to create a good seal and prevent leaks.
- For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation.
- Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows away from the unit smoothly.
Notes
- Do not kink the drain hose.
- Do not create a water trap (siphon).
- Do not put the end of the drain hose in water or in a container that will collect water.
