Please fasten the installation stand firmly with bolt or nails. - Page 25 4(A). Checking gas leakage for left piping 1) a. Connect the manifold gauge to the service port of 3-way valve. b. Measure the pressure. 2) a. Keep it for 5-10 minutes. b. Ensure that the pressure indicated on the gauge is the same as that of measured during the first time. Evacuation (vacuum method) is recommended, for model 2.0 HP ~ 3.0 HP with the piping length more than 5 meter.
- Page 26 • If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in step above take the following measure: - If the leak stops when the piping connections are tightened further, continue working from step - If the leak does not stop when the connections are retightened, repair the location of leak.
