Figure 45: Insulating the Piping.
WARNING
Ensure all refrigerant piping is insulated. Any exposed piping will cause burns if touched.
Wrap all refrigerant and condensate piping including field-provided isolation ball valves and flexible pipe connection kits provided by LG. All
pipes must be insulated and each pipe must be separately wrapped. Any exposed piping may generate condensate; sufficiently insulate all
cold surfaces to prevent moisture forming.
Ensure insulation material fits snugly against the refrigeration pipe with no air space between the pipe surface and the surrounding insula-
tion.
Protect insulation inside hangers and supports with a second insulation layer. Ensure insulation on all pipe passing through pipe hangers,
inside conduit, and/or sleeves is not compressed.
Glue all insulation joints with no air gaps. Be sure insulation material fits snugly against the refrigeration pipe with no air space between it
and the pipe. All pipe insulation exposed to the sun and outdoor elements must be properly protected with PVC, aluminum vapor barrier, or
alternatively placed in a weather-resistant enclosure such as a pipe rack with a top cover; and must meet local codes. Pay special attention
to insulating the pipes installed in a ceiling plenum.
