Do the heat insulation to the pipes of gas side and liquid side separately. The
temperature of the pipes of gas side and liquid side when cooling, for avoiding
condensation please do the heat insulation fully.
1) The gas side pipe should use closed cell foamed insulation material, which the fire‐
retardant is B1 grade and the heat resistance over 120 ℃.
2) When the external diameter of copper pipe≤Φ12.7mm, the thickness of the
insulating layer at least more than 15mm; When the external diameter of copper
pipe≥Φ15.9mm, the thickness of the insulating layer at least more than 20mm.
3) Please use attached heat‐insulating materials do the heat insulation without
clearance for the connecting parts of the indoor unit pipes.
