Prepare the Refrigerant Piping of the Indoor Unit for Wall-Mounted SystemsUpdated 4 days ago
Introduction
This article explains how to prepare the refrigerant piping of the indoor unit for wall-mounted systems.
The piping "pigtails" pre-attached to the indoor unit can be run in three different methods. Decide which type of configuration is most suitable before continuing.
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)
Configuration Options
Option 1: By default, the refrigerant piping is routed for a left side exit. This method can either use the left side knockout for a side exit or a wall hole can be drilled on the left side of the unit's rear.
Option 2: Routing the refrigerant piping straight through the back of the system will facilitate the connections to the copper pipe extensions intended to be made outside. This is recommended to simplify the process.
Option 3: This method is a right side exit, but is not recommended as it involves a 180° bend of the piping. This increases the risk of kinking or collapsing the lines dramatically. Bend the piping slowly and cautiously.
Notes
- If a side-exit is chosen, there are knock-out panels on either side of the unit that can be cut along the groove to provide a notch for the pipe to exit from. Use a suitable cutter to do this.
- Run the piping in the direction of the wall hole.
- Bind the copper pipes, drain pipe, and power cables together with tape. Ensure that the bundle is exiting at a continuous downward pitch.
- Keep the drain hose at the bottom so that the water can flow freely.
- Do not remove the seal caps from the pipe ends until it is time to connect it, avoiding contaminants from entering.
- If the pipe is bent/pulled too often, it will become still. Don't bend the pipe more than three times at one point. Be careful not to kink any piping.
- When extending the coiled copper pipes, straighten them by unwinding gently.
