Advantage
The sight glass adopts a separate structure of sight glass and valve seat, which is easy and convenient to disassemble. The lens is made of low-temperature and explosion-proof tempered glass, and the outer ring is precisely gold-plated for high safety. The welding and screw joints adopt an explosion-proof crimping structure design, with clear tightening feedback to ensure safer operation.
The welding joint adopts high-frequency welding technology, with the current highly concentrated in the welding area. The heating speed is fast and the heat affected zone is small, which is not easy to cause changes in component performance. The weld structure and performance are excellent, and the welding surface penetration is uniform and aesthetically pleasing.

Instruction
Install the sight glass into the refrigerant line. Observe the sight glass during operation to check if the flow and the condition of the refrigerant are normal or not. Green means no high moisture in refrigerant. Yellow means the moisture content is too high in refrigerant.

NOTE
Before installation, it is necessary to turn off the power supply of the refrigeration equipment, release the pressure inside the system, and ensure safe operation.
