REFRIGERANT PIPING CONNECTIONS
Bundling and Cutting Line
Piping and cabling must be insulated and bundled together correctly for safety and usage. Follow proper methods and procedures as outlined
here and on the next pages to ensure installation and piping are correctly installed.
Insulation material
As shown in Figure 64, the connection pipe, along with the indoor
unit pipe are fully encased in insulation material.
1. Bind together the two pipes, using vinyl tape. Make sure there
are no gaps during the binding.
2. Be sure the tube cutting line is placed upward (Figure 65).
3. Verify that rear piping house section is wrapped with vinyl tape.
• Use a narrow type of vinyl tape for this step.
4. Continue to wrap the Indoor unit pipe as connected to the outdoor
connection pipe as shown in Figure 66.
