• BioShield system equipped with an 80-watt UV lamp

We recommend checking the model number listed on your BioShield system before ordering.

Function of the quartz sleeve

The quartz sleeve is installed around the UV lamp inside the BioShield system.

It notably:

• Protect the lamp from direct contact with water
• Allow ultraviolet light to pass through
• Maintain the watertight seal of the lamp compartment
• Facilitate removal and maintenance of the UV lamp
• Help ensure the proper operation of the BioShield system

Mineral deposits and dirt accumulated on the quartz can reduce the passage of UV light. The sleeve must therefore be inspected and cleaned periodically.

When should the quartz sleeve be replaced?

Replacement may be necessary when:

• The sleeve is cracked or broken
• The quartz is scratched or damaged
• The deposits can no longer be removed
• Water infiltration is observed around the lamp
• The sleeve was damaged during maintenance
• The BioShield system requires refurbishment

A cracked sleeve must not be reinstalled in the system.

Installation and handling

Quartz is a fragile material that must be handled with care.

Before installation:

1. Completely disconnect the system from the electrical power supply.
2. Stop the circulation pump.
3. Close the necessary valves.
4. Depressurize and drain the BioShield system.
5. Carefully remove the UV lamp.
6. Inspect the seals and retaining components.
7. Install the new sleeve according to Pentair instructions.
8. Check for leaks before powering the system back on.

Professional installation is recommended to prevent breaking the sleeve or damaging the UV lamp.

Maintenance tips

• Handle the sleeve with clean hands or gloves
• Avoid impacts and twisting
• Clean the quartz with a suitable product
• Do not use a wire brush
• Inspect the seals every time the system is disassembled
• Replace damaged or hardened seals
• Check for cracks before reinstalling
• Never power on the system without adequate circulation
