Step 1. Close the System Main Control Valve (2).
Step 2. Close the Diaphragm Supply Valve (5) and Air Supply Valve (27).
Step 3. Open the Main Drain Valve (4), System Drain Valve (23), and all auxiliary drains in the system. Close the
auxiliary drain valves and the System Drain Valve (23) after water ceases to discharge. Leave the Main Drain
Valve (4) open.
At this time make certain that the Pressure Gauge Valves and the Alarm Control Valve (OP 1), as applicable,
are open.
Do not open the Inspector’s Test Connection and auxiliary drains if resetting after a system test; otherwise,
system air pressure will be relieved unnecessarily.
Step 4. Depress the plunger of the Automatic Drain Valve (3) to verify that it is open.
Step 5. Clean the Diaphragm Supply Strainer (13) by removing the clean-out plug and strainer basket. The Dia-
phragm Supply Strainer (13) may be flushed out by momentarily opening the Diaphragm Supply Valve (5).
Step 6. Inspect for and clear all ice plugs where system piping has been exposed to freezing conditions and
when there has been a flow of water into the system.
