strainer reduces the injector operating water pressure. If the pressure drop is
excessive, the injector will not be able to induct the required gas flow. Regular
periodic inspection and cleaning of the strainer will minimize this possibility.
4.9 Installation of Throat and Tailway
The throat and tailway must be assembled as shown on the parts drawing. If
faulty injector action is suspected, inspect the gaskets and O-rings and replace
them if there is any doubt about their condition.

4.11 Maintenance
Maintenance of a Series V-2000 Gas Feeder consists of three periodically
performed operations:
• Periodic Performance Checks to detect the onset of any deteriorating
conditions before their progress leads to serious malfunction.
• Periodic Cleaning to remove contaminants and deposits brought to the
vacuum regulator(s) and control module by the gas flow and to the injector
by the water flow.
• Periodic Preventive Maintenance to disassemble, inspect, clean, and ac-
complish recommended parts replacement. Kits of replacement parts re-
quired for this periodic maintenance are available and are listed in Section
6 - Preventive Maintenance Kits and Spare Parts List.
