How the ADV works The Spirax-Monnier ADV trap consists of:
- A poppet valve. - A direct acting solenoid. - Twin solid state variable timers, with LED status indication. - Plug connector. - Brass valve body.
With the correct power supply connected, and the system pressurized, the timers can be set: - The 'On' timer ( 1 ) controls the discharge period (0.5 to 10 seconds). - The 'Off' timer ( 2 ) determines the frequency of discharge (0.5 to 45 minutes).

- Site conditions (quantity of condensate to be discharged, and amount and type of contamination) will determine the timer setting. - The LED indicates which timer circuit is live ( 3 and 4 ). Operation of the 'test' facility will energise the 'On' timer circuit, opening the discharge valve.The valve will remain open as long as the test button is depressed. This action also resets the 'Off' timer to its start position. The condensate can be discharged to atmosphere ( 5 ) or piped away to a suitable container.
Installation note On systems with high levels of solid particulate contamination, it is recommended that a strainer (Spirax Sarco Fig 12 Brass) be fitted immediately upstream of the ADV. To simplify routine maintenance and cleaning, a self-venting isolating ball valve should be installed, before the ADV (Spirax-Monnier venting ball valve). All connections should be made with 0.4/1.5 mm² 3 core wire of a rating to suit the supply voltage. The unit should be installed with the timer and solenoid sections vertical and the main brass valve body horizontal. The valve body can be rotated horizontally through 360° relative to the solenoid, for ease of installation. Note: the direction of flow arrow on the valve body. Recommended fuse protection 1 amp.
