Bundling And Cutting Line - LG LA090HVP Installation Manual

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.
As shown in Figure 38, 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 39).
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 40.

rear piping housing area at the back of the indoor unit (Figure 36
on previous page).
