〈
Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed
86ºF or RH80 %, reinforce the refrigerant insulation. (13/16” or thicker) Condensation may form on
the surface of the insulating material.

〈
Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not
possible if the types of refrigerant are not the same.
