ALWAYS FLUSH THE SYSTEM BEFORE INSTALLING THE ACV200!

Special note for MAINLINE INSTALLATION, always install a manual shutoff valve beneath the

ACV200! See the illustration. The reason for this recommendation is to avoid having to shut off

the mainline and drain off the pressure before the ACV200 can be unplugged and reinstalled.

Make special note to all people that service the ACV200 that the manual valve must be left in

the open position during operation in order for the ACV200 to function.

CAUTION! Pipeline debris will tend to migrate to the ACV200 Air Control Valve on start of a

new system. Occasionally debris will get caught at the seal and cause it to leak.

RECOMMENDATIONS:

· Use Teon tape on the connection thread. Do not use

pipe dope.

· Provide draining for the ACV200 in freezing weather.

· The Seal was redesigned in November 2015 to resist

pump lubricants. Seal upgrade kit #10630 is available for

units manufactured before this date.

· *The ACV200 has a built in turbulence suppression feature

to help stabilize the oat. For best performance locate the

ACV200 in the pipeline where the air is separated from

the water and the air can freely vent out.

· Be sure to mount the ACV200 in the upright position

because the oat must be free to pull the seal downward

to release air.

· Refer to the Nelson “ACV200 AIR CONTROL VALVES

Technical Application Guide” document for detailed

information about the best practices and use of the

ACV200 in irrigation systems.

*For valves having plastic base manufactured prior to 2007 there is a base service kit available so that the turbulence

suppression feature can be installed. The service kit numbers are 11144-001 for NPT and 11144-002 for BSP thread.

The turbulence suppression feature is not available for the brass base version of the ACV200B.
