Refrigerant Piping

Pipe Insulation - continued
— The thickness may need to be increased based on ambient
conditions and local codes.
• Wrap all refrigerant and condensate piping, including field-provided
isolation ball valves and pipe connection kits provided by LG.
• Glue all insulation joints (see Figure 15).
— There should be no air gaps between insulation segments, or
between the insulation segments and the unit case.
— Fit insulation material snugly against refrigeration pipe. There
should be no air space between pipe surface and surrounding
insulation.
• Do not compress the insulation in areas where the piping passes
through pipe hangers, conduit, and/or wall sleeves.
— Protect insulation from compression inside hangers and sup-
ports by wrapping with a second layer.
condensate Piping for Hydro Kit High temperature (K3) only
• The Hydro Kit condensate line connection is designed to be a gravity drain. If a condensate pump is required, it shall be field provided and
installed external to the unit case.
• Slope drain line a minimum of 1/4" per foot of horizontal run away from the unit case. Properly vent the condensate line per industry standard
practices. See Figure 17.
While making pipe connections, be careful to support pipe to avoid placing lateral force on the drain nipple. Internal damage may occur.
• Condensate pipe connection is 1" male pipe thread.
