Raypak 406/407 Tube Bundle Polymer Kit | 010062F

Raypak 010062F Copper Tube Bundle Kit – For 406A / 407A Heaters with Polymer Headers

The Raypak 010062F is a complete copper heat exchanger tube bundle kit designed for select Raypak 406A and 407A Digital Low NOx pool & spa heaters that use polymer headers. This kit is typically replaced when the existing heat exchanger is leaking, scaled internally, or has restricted flow from corrosion or debris.

Key Features

• Part Number: 010062F
• Type: Copper tube bundle / heat exchanger core (kit)
• Material: Copper
• Designed For: Raypak 406A and 407A heater families with polymer headers
• Purpose: Restores proper heat transfer and water flow through the heater

What’s Included

• Copper tube bundle (heat exchanger core)
• Baffle
• Flange nut kit
• (2) O-ring gaskets

Common Signs You Need a New Tube Bundle

• Water leaking from the heat exchanger/header area
• Reduced heater performance (longer heat-up times)
• Flow-related shutdowns after confirming pump/filter are operating correctly
• Visible internal corrosion, heavy scale, or pinhole leaks

Compatibility Notes

• Polymer header application: This tube bundle is intended for heaters configured with polymer headers.
• Verify by model/serial: Raypak parts can vary by revision—match your heater’s model/serial and parts breakdown before ordering.
• Replace gaskets during install: Always install the included O-rings/gaskets (reusing old seals often causes leaks).

Installation & Maintenance Tips

• Shut off power and gas, relieve system pressure, and allow the heater to cool fully before service.
• Clean mating surfaces and inspect header sealing areas for pitting/warping before installing the new bundle and O-rings.
• Tighten fasteners evenly in a crisscross pattern to prevent pinched seals and leaks.
• Maintain proper water chemistry—aggressive water and low pH are common causes of premature copper heat exchanger failure.
• Keep filters clean and verify proper flow rate; low flow can overheat the exchanger and accelerate damage.
• If you have hard water, monitor calcium hardness and manage scale to protect the heat exchanger from internal buildup.
