Please pay attention to avoid the components where it is connecting to the connecting pipes.
CAUTION
To prevent the refrigerant piping from oxidizing inside when welding, it is necessary to charge nitrogen, or oxide
will chock the circulation system.

7.3 Heat insulation
In order to avoid the release of cold or heat from the connecting pipeline to the external environment during the operation of the equipment,
please take effective insulation measures for the gas pipe and liquid pipe separately
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.
