Quartz Sleeve Cleaning
It is recommended that the quartz sleeve be visually inspected for cleaning once every six months of operation. Even the
slightest layer of material (slim/dirt) coating the outside of the quartz sleeve can have a substantial affect on UV-C light
transmittance through the glass and into the water.
To Clean the Quartz Sleeve (for above water-level installations only):
1. Disconnect power to the UV sterilizer and pool pump at the circuit breaker.
2. Relieve any residual pressure that may remain in the system.
3. Unthread the Black Retaining Nut and gently remove the Quartz Sleeve Assembly and lamp from the UV vessel.
4. Inspect the Quartz Sleeve and clean as needed with a soft, clean cloth.
5. If calcium deposits are present use vinegar or a mixture of water and muriatic acid to dissolve the deposits. If using
muriatic acid a ratio of four parts water to one part acid should suf ce. Always introduce acid to the water and never
introduce the water to the acid.
6. Remove ALL vinegar or acid from the quartz sleeve assembly before reassembling.
Winterizing
Using the Bioshield
®
UV Disinfection Sterilizer in extremely cold temperatures can cause damage to the unit, especially if
the water is allowed to freeze inside the equipment. Please note that damage to the product due to freezing is not covered
under warranty.
Pentair recommends shutting the UV system down when the temperature consistently falls below 40°F (4°C).
1. Drain all water from the UV system.
2. Disassemble the entire unit and carefully clean both the outside and interior of the UV body and components.
3. Once clean and dry, store the UV vessel and power supply in a dry place for the winter.
4. Return the UV system to service when temperatures consistently return to 40°F (4°C) or greater.
Note: Be sure to replace the quartz sleeve gasket/o-ring and perform a leak test prior to operating the equipment.
Muriatic acid is corrosive and can lead to in ammation or burns to body tissue. ALWAYS wear
rubber gloves, safety glasses and an N-95 dust mask when handling acid to prevent serious bodily
injury.
