Insulate Pipes - LG Multi V Installation Manual

Install Refrigerant Pipe Insulation
Figure 19 shows typical pipe insulation. Insulate all field provided refrigerant pipes and cold surfaces according to these guidelines:
• Insulate all cold surfaces sufficiently to prevent moisture from forming on the surface. All pipes must be insulated and each pipe must
be wrapped separately.
• Use field-provided 1/2" thick (or more) closed cell insulation. The thickness may need to be increased based on ambient conditions
and local codes.
• All refrigerant a condensate piping including field-provided isolation ball valves and flexible pipe connection kits provided by LG should
be wrapped.
• All insulation joints should be glued with no air gaps between insulation segments and between insulation segments and the unit case.
Insulation material shall fit snugly against the refrigeration pipe with no air space between the pipe surface and the surrounding insula-
tion. See Figure 19.
• All pipe passing through pipe hangers, inside conduit, and/or sleeves must not be compressed. Protect insulation inside hangers and
supports with a second layer.
