4.11.7
Cleaning 3/4" Fixed Throat Injector (Anti-Syphon) (See Dwg. 25.200.002.020)
The check valve prevents water from the injector from being drawn back by the
vacuum prevailing at shutdown into the control unit and toward the vacuum
regulator during the OFF period.
In continuous or nearly continuous operation, this valve is actuated very little,
and the recommended annual check is principally to assure cleanliness. In auto-
matic start-stop operation, the check valve can accumulate thousands of open-
ing and closing cycles in six months or less and wear becomes a consideration
in addition to clean surfaces. For either interval the procedure is as follows:
• Cleaning Injector Unit Diaphragm Backcheck.
a. Shut off injector operating water.
b. Take steps to prevent water flowing back toward the injector from the
point of application.
c. Unscrew gas line tubing nut and remove tubing.
d. Unscrew injector body union nut (10).
