1. Introduction
The Raypak 017960F Protek Shield-Kit is a critical component designed to protect your Raypak digital gas pool heater's heat exchanger from corrosion. This innovative module functions as a sacrificial anode, attracting and absorbing corrosive elements that would otherwise degrade the heater's internal components. Regular replacement of the Protek Shield-Kit helps extend the lifespan of your pool heater, particularly in environments with chlorinated or saltwater.
2. Safety Information
Always prioritize safety when working with pool equipment. Read and understand all instructions before proceeding with installation or maintenance. If you are unsure about any step, consult a qualified pool technician.
- Ensure the pool heater is turned off and disconnected from all power sources before beginning any work.
- Allow the heater to cool down completely before handling any components.
- Wear appropriate personal protective equipment, such as gloves and eye protection.
- Keep children and pets away from the work area.
- Dispose of old components responsibly according to local regulations.

Verify that all components are present and undamaged before installation.

Image Description: This image displays the complete Raypak 017960F Protek Shield-Kit. On the right is the main shield unit, a clear cylindrical component with a threaded end. To the left, a black electrical wire is shown, coiled, with a yellow-insulated ring terminal at each end. A black O-ring is also visible, positioned within the coil of the wire.
The Raypak 017960F Protek Shield-Kit typically includes:
- 1 x Protek Shield Unit (clear cylindrical component)
- 1 x Grounding Wire with Ring Terminals
- 1 x O-ring
4. Setup and Installation
The Protek Shield-Kit is designed for straightforward replacement in compatible Raypak digital gas heaters. Installation typically takes a few minutes.
- Preparation: Ensure the heater is powered off and cooled. Locate the existing Protek Shield unit on your Raypak heater.
- Removal of Old Unit: Carefully unscrew and remove the old Protek Shield unit. Note the condition of the old unit; significant erosion indicates it was performing its function. Disconnect the grounding wire if it is attached to the old unit.
- O-ring Installation: Apply a small amount of silicone-based lubricant to the new O-ring. Place the O-ring onto the new Protek Shield unit. This helps ensure a watertight seal and easier installation.
- New Unit Installation: Carefully thread the new Protek Shield unit into its receptacle on the heater. Ensure it engages properly to avoid cross-threading. If resistance is met, remove, inspect the threads, and reattempt. Some users have reported needing to slightly adjust the lead-in thread of the new unit if it struggles to catch the female thread.
- Grounding Wire Connection: Connect the provided grounding wire (or reuse the existing one if in good condition) to the new Protek Shield unit and the designated grounding point on the heater. Ensure a secure connection.
- Leak Check: Once installed, restore power to the heater and check for any leaks around the newly installed shield unit.
Note: A strap wrench may be useful for removing stubborn old units.
5. Operating Instructions
The Raypak Protek Shield-Kit operates passively once installed. Its function is to continuously protect the heat exchanger from galvanic corrosion by acting as a sacrificial anode. No user interaction is required during its operation.
6. Maintenance
For optimal protection and to ensure the longevity of your pool heater, it is recommended to inspect and replace the Raypak Protek Shield-Kit annually. The shield unit will gradually erode over time as it performs its protective function. A visibly eroded shield indicates it has been working effectively and requires replacement.
- Annual Inspection: During routine pool heater maintenance, visually inspect the Protek Shield unit for signs of erosion.
- Replacement: Replace the unit if it shows significant wear or annually, whichever comes first. Refer to the "Setup and Installation" section for replacement steps.
