3 START-UP
3.1 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. The ejector should now be in operation and creating a
vacuum.
3.1.3 Put your finger on the vacuum connector opening and feel the vacuum. There should be no
doubt that a vacuum exists. If there is no vacuum, be certain the supply pressure is sufficient
and the nozzle or piping is not plugged. Correct the condition and obtain proper vacuum before
proceeding with vacuum regulator operation. (Reference vacuum regulator instruction manual)
3.1.4 Reconnect the vacuum tubing to the ejector. Leave the ejector running.
