Connection of high/low pressure common pipe
1. For the high/low pressure common pipe, connect both master outside unit and slave outside units to the pipe by
using elbows.
2. For cutting the pipe, connect the high/low pressure common pipe after removing burrs, dusts and foreign
material within the pipe. Otherwise, the product may not operate due to sludge within the pipe.
3. For the working part leakage test, apply the nitrogen gas pressure of 3.8MPa (38.7kgf/cm
2
).
4. The vacuum criteria is to maintain the vacuum level to less than 5 Torr 1 hour after reaching 5 Torr. (Execute
the vacuum work again when it is below the criteria.)
5. Open the valve with the hexagon wrench.
