Installation Instructions

1. Prepare Tank Wall: Mark and cut a hole to the required diameter for the connector.

2. Position Flanged Connector: Insert the connector through the hole from the inside of the tank. Ensure that the supplied sealing washer is in place on the flange side.

3. Secure with Backnut: From the outside of the tank, thread the backnut onto the connector and tighten firmly to compress the seal.

4. Attach Pipework: Connect pipework to the outlet side using compression fittings or soldering, depending on system requirements.

5. Check for Leaks: Fill the tank and check all joints and seals under pressure.

Tip: Always flush the system before final installation to remove debris that could damage the sealing washer or internal pipework.

Maintenance Advice

• Inspect Annually: Check the seal and surrounding area for any signs of weeping, scaling, or corrosion.

• Replace Washer as Needed: If the seal shows wear or cracking, replace the washer to maintain water-tight performance.

• Tighten Backnut If Necessary: Over time, the backnut may loosen due to temperature changes or movement. Re-tighten gently if needed.
