1. Preparation: Ensure the heater is turned off, disconnected from power, and completely cooled. Drain the water from the heater.
2. Access: Carefully remove the heater casing and any other components obstructing access to the existing tube bundle.
3. Removal of Old Bundle: Disconnect all plumbing and gas connections as necessary. Unbolt and carefully remove the old tube bundle. Note the orientation for proper installation of the new unit.
4. Inspection: Inspect the heater's combustion chamber and surrounding areas for any debris, corrosion, or damage. Clean as necessary.
5. Installation of New Bundle: Carefully position the new Raypak Tube Bundle (006711F) into the heater. Ensure all gaskets and seals are correctly seated. Secure with appropriate fasteners, tightening them evenly to prevent leaks.
6. Reconnection: Reconnect all plumbing and gas lines. Refill the heater with water and check for leaks before restoring power.
7. Testing: Once reassembled, perform a thorough operational test to ensure proper function and absence of leaks.

5. Operation

The tube bundle is a passive component within the heater's heat exchange system. Its operation is integral to the overall function of the Raypak pool/spa heater. Once installed, the tube bundle facilitates the transfer of heat from the combustion gases to the circulating pool or spa water. Proper installation ensures efficient heat transfer and prevents water or gas leaks.

6. Maintenance

Regular maintenance of your pool heater, including the tube bundle, is crucial for its longevity and efficiency. It is recommended to have your heater inspected annually by a qualified technician.

• Visual Inspection: Periodically inspect the tube bundle for signs of corrosion, scale buildup, or leaks.
• Cleaning: If scale or debris buildup is observed, consult a professional for appropriate cleaning methods. Harsh chemicals can damage the copper tubes.
• Water Chemistry: Maintain proper pool/spa water chemistry to prevent scaling and corrosion, which can significantly impact the tube bundle's lifespan.
• Ventilation: Ensure the heater area has adequate ventilation to prevent issues related to combustion and heat dissipation.

7. Troubleshooting

Issues related to the tube bundle typically manifest as reduced heating efficiency or water leaks. Due to the complexity of pool heater systems, professional diagnosis is always recommended.

• Reduced Heating: If the heater is running but not effectively heating the water, the tube bundle may have scale buildup or internal damage reducing heat transfer.
• Water Leaks: Leaks from the heater's heat exchanger section often indicate a compromised tube bundle. Immediately shut down the heater and consult a technician.
• Unusual Noises: Gurgling or hissing sounds from the heat exchanger could indicate issues with water flow or internal damage.

For any significant operational issues, contact a qualified Raypak service technician.
