INTRODUCTION General ® The ADVANCE ejectors are expertly engineered and carefully tested to assure yearsof satisfactory operation. They are constructed of the finest materials available for gas service. Correct installation and proper care will ensure best operation. Read instructions carefully and save for future reference. This instruction manual only covers our standard O-Ring ejector (Reference 122.3001). -

2.2.3 Reconnect nozzle and check valve assembly to diffuser. The nozzle may extend through the assembly from either side. A gasket should be on each side. Screw the nozzle into the diffuser HAND TIGHT. (The check valve assembly may be installed in any position.) 2.2.4 Other types of diffuser and ejector installations may be desired for certain applications: The ejector (nozzle and check valve assembly) may be located near the vacuum regulator. -
Page 7: Start-Up
START-UP Vacuum Check The ejector, its water supply and solution lines, must be properly installed and checked before operating the vacuum regulator. Unless the ejector is creating a vacuum, the vacuum regulator will not work. 3.1.1 Disconnect the vacuum tubing from the ejector. 3.1.2 Open the ejector water supply valve. -
Page 8: Shutdown
SHUTDOWN WARNING Before disconnecting or disassembling the ejector, shutdown the system as described below. Failure to do so may result in serious injury or death. Close the gas supply valve at the pressure source(s) to shut off the gas flow. This is normally the gas cylinder and/or container valve(s) supplying the gas dispensing (regulator) system. -
Page 9: Service
SERVICE It is recommended that the Gas Dispensing System be inspected and serviced a minimum of once per year. More frequent service periods may be required due to: 1) the type, quality and quantity of the gas being handled, 2) the complexity of the gas supply system, 3) the quality and quantity of water or process liquid being used to operate the ejector(s), and 4) operation procedures. -
Page 10: Functional Test
Functional Test When the ejector is reassembled, a functional test of the check valve assembly is recommended to check for proper ejector assembly and prevent future flooding of the vacuum regulator. 5.4.1 Do not connect vacuum tubing to vacuum regulator. 5.42 Turn on water supply. - Page 11 Figure 2 - 100 PPD (2 kg/h) Ejector - 11 - 122.6006.9...
