Hi!
To remove and replace the fluid in your Dwyer 400-5-GAGE, start by ensuring that the gauge is not under pressure and that the pressure source is isolated. You’ll want to handle this process carefully, so make sure you have the replacement fluid that matches the manufacturer’s specifications, along with a syringe or fluid pump for ease of handling. The high-pressure port is typically where you'll add or remove the fluid, but it’s always good to double-check the gauge's manual for specific instructions.
Begin by carefully draining the old fluid; if there’s a dedicated drain port, use that; otherwise, you may need to remove the fill plug to let the old fluid escape. After draining, clean any residues inside the gauge with a cloth. Refill the gauge slowly with new fluid through the appropriate port, using the syringe or pump, and be cautious to avoid air bubbles. If the gauge needs bleeding to remove air, follow the manufacturer’s guidance, which might involve gently tapping the gauge or adjusting the fluid level. Once refilled and bled, reassemble the gauge, reconnect any pressure lines or mounting hardware, and gradually reintroduce pressure to ensure everything is functioning correctly. Finally, clean up any spills and properly dispose of the old fluid. Always refer to your gauge’s manual for any specific details or precautions.
