4. Setup and Installation

Follow these steps for proper installation of the Tivora EWD 330 drain valve.

1. Verify Compatibility: Before installation, ensure the drain valve is compatible with your system. Check the part numbers (EWD330, 1622855181, 2901146551, EWD330M) against your existing equipment.
2. Depressurize System: Ensure the compressed air system is completely depressurized and isolated from power before proceeding.
3. Mounting: Mount the drain valve in a suitable location, typically at the lowest point of the condensate collection vessel (e.g., air receiver, filter, dryer). Ensure it is installed vertically with the drain outlet facing downwards.
4. Connect Condensate Lines: Connect the condensate inlet from your system to the "IN" port(s) of the drain valve. Connect a suitable drain line to the outlet port for safe disposal of condensate. Ensure all connections are tight to prevent leaks.
