3. Setup and Installation
Proper installation is crucial for accurate readings and safe operation. Ensure the gauge is securely connected to the pressure source.
- Inspect the Gauge: Before installation, visually inspect the gauge for any signs of damage.
- Prepare Connection Point: Ensure the pressure connection point is clean and free of debris.
- Connect the Gauge: The DPG Series features a 1/4" NPT 304SS Stainless Steel connection. Carefully thread the gauge into the pressure port. Use appropriate sealing tape or compound if necessary, ensuring it does not obstruct the pressure port.
- Tighten Securely: Hand-tighten the gauge first, then use a wrench to tighten it securely. Do not overtighten, as this can damage the threads or the gauge.
- Verify Orientation: Ensure the gauge display is oriented for easy viewing.
