Refer to Technical Data for the accelerator used. Verify that the water supply main control valve is open and all trim valves are in their normal operating position.
If detected, perform maintenance as required or, if necessary, replace the device. Verify that dry valve and trim are adequately heated and protected from freezing and physical damage. Notify the Authority Having Jurisdiction and those in the area affected by the test. Note: Viking Conventional Trim provides a connection for installation of a non-interruptible pressure switch. See Dry Valve Trim Chart. Fully open the main drain located on the base of the dry valve to flush away any accumulation of foreign material.

Main Drain Test Quarterly performance of the Main Drain Test is recommended and may be required by Authorities Having Jurisdiction to verify integrity of the water supply. Record pressure reading from the water supply pressure gauge.
Verify that the dry pipe system is pressurized at or above the minimum pressure recommended in Table 3 for the water supply pressure available. Fully OPEN the main drain located on the base of the dry valve.
When a full flow is developed from the main drain, record the residual pressure from the water supply pressure gauge. Compare test results with previous flow information. If deterioration of the water supply is detected, take appropriate steps to restore adequate water supply.
Verify that normal water supply pressure and system pneumatic pressure have been restored, and that all alarm devices and valves are secured in normal operating position. Notify the Authority Having Jurisdiction that the test is complete.
Quarterly testing of low air alarms is recommended. Close the water supply main control valve supplying the dry valve. If the dry valve being tested is equipped with a Viking accelerator and external anti-flood device installed according to Viking Model E-1 Accelerator Trim Charts, performing steps 6 or 7 of this test will cause the accelerator to operate.

Low Air Alarm Test: a. Gradually open the priming level test valve in the trim of the dry valve to simulate operation of the dry system. Observe and record the pressure at which the low air alarm operates. Close the priming level test valve.
If the dry valve being tested is equipped with a Viking accelerator and external anti-flood device: a. Loosen use the appropriate wrench , and remove the accelerator air gauge to release pressure from the upper chamber of the accelerator.
