Installation Guide

🔧 Step 1: Preparation

• Ensure the system is depressurized before installation.
• Confirm the pressure range and connection type match your system.

🔧 Step 2: Mounting the Gauge

• Connect the gauge to the system via the 1/4″ BSP Male back connection.
• Use Teflon tape or pipe sealant to prevent leaks.
• Tighten by hand first, then secure with a wrench without over-tightening.

🔧 Step 3: Checking for Leaks

• Slowly pressurize the system and check for leaks.
• Tighten the connection if needed or apply additional sealant.

Maintenance & Care

🛠 Regular Inspection

• Periodically check for damage, cracks, or signs of leakage.
• Ensure the needle moves smoothly without excessive vibration.

🛠 Cleaning

• Wipe the dial and casing with a soft cloth. Avoid harsh chemicals.
• Remove dust and debris from the connection ports as needed.

🛠 Glycerine Level Check

• Ensure the glycerine fill level is sufficient for stable readings.
• If depleted, consider refilling or replacing the gauge.

🛠 Storage Guidelines

• Store in a cool, dry place away from direct sunlight and corrosive environments.
• Avoid extreme temperature fluctuations to maintain accuracy and longevity.

🛠 Replacement Recommendation

• If the gauge shows inconsistent readings or a stuck needle, replace it for system safety.
• For high-vibration environments, consider a shock-resistant or liquid-filled gauge.
