• 1 × UV57LAMP — Replacement UV Lamp
• 1 × UV57SLEEVE — Replacement UV Sleeve
• 2 × O-rings
• 1 × 20PP10 — 20 Micron Poly Pleated Water Filter Cartridge
• 1 × 1PS10 — 1 Micron Polyspun Water Filter Cartridge

Everything is supplied together as a Genuine Davey service kit.

Compatible Davey Systems

The 57-SERVKIT-RN suits:

• Davey KUV57A
• Davey UV57 with prefiltration

Always check the model of your existing Davey system before ordering to confirm compatibility.

Why Choose the Complete Service Kit?

A UV water treatment system relies on both effective prefiltration and UV treatment.

The two sediment filters progressively remove suspended particles before the water reaches the UV chamber, while the lamp and sleeve form the key service components of the UV treatment stage.

The 57-SERVKIT-RN allows you to replace these components together as part of a complete system service.

Complete Service in One Kit

The kit provides the filtration sequence:

20 Micron Poly Pleated → 1 Micron Polyspun → UV Treatment

along with the replacement UV sleeve and O-rings.

Genuine Davey Components

The 57-SERVKIT-RN is a Genuine Davey service kit, providing matched replacement components for compatible Davey KUV57A and UV57 systems.

Filtration + UV Maintenance

This is more than just a replacement UV lamp.

The kit refreshes both the prefiltration and UV treatment components, making routine maintenance easier and removing the need to purchase each service component separately.

How the Filtration Stages Work

Stage 1 — 20PP10 20 Micron Poly Pleated Filter

The 20PP10 20 micron poly pleated cartridge provides the first stage of filtration.

It captures larger suspended sediment and particles before the water reaches the finer second-stage filter.

The pleated media provides a large filtration surface area, making it well suited to first-stage sediment filtration.

Stage 2 — 1PS10 1 Micron Polyspun Filter

Water then passes through the 1PS10 1 micron polyspun cartridge.

This provides finer sediment filtration, capturing smaller suspended particles that pass through the first-stage cartridge.

Together, the two cartridges provide progressive filtration:

20 Micron Pleated → 1 Micron Polyspun

This prepares the water before it reaches the UV treatment stage.

UV Treatment Stage

After prefiltration, the water passes through the UV treatment stage.

The UV57LAMP produces ultraviolet light inside the UV chamber, while the UV57SLEEVE separates the lamp from the water while allowing the UV light to pass through.

Replacing the lamp and sleeve as part of a complete service helps keep the UV stage properly maintained.

Installation

The 57-SERVKIT-RN contains components for both the filtration and UV sections of the system.

A typical service involves:

1. Turn off power to the UV system.
2. Isolate the water supply.
3. Release pressure from the filtration system.
4. Remove the existing filter cartridges.
5. Clean the filter housings as required.
6. Install the new 20PP10 20 micron pleated cartridge in the appropriate first-stage housing.
7. Install the new 1PS10 1 micron polyspun cartridge in the appropriate second-stage housing.
8. Carefully remove the existing UV lamp.
9. Remove the existing UV sleeve as required.
10. Install the new UV57SLEEVE and supplied O-rings.
11. Carefully install the new UV57LAMP.
12. Reassemble the system.
13. Slowly restore the water supply.
14. Check thoroughly for leaks.
15. Restore power and confirm correct system operation.

Follow the servicing procedure for your specific Davey system when installing the kit.

UV Lamp & Sleeve Handling

Take care when handling the replacement UV components.

Avoid touching the glass surface of the UV lamp with bare fingers. Oils and contaminants from your skin can remain on the lamp surface.

The UV sleeve is also fragile and should be handled carefully during removal and installation.

Ensure the supplied O-rings are correctly seated during reassembly to maintain a proper seal.

Why Replace the UV Sleeve?

The UV sleeve separates the lamp from the water while allowing ultraviolet light to pass into the treatment chamber.

Over time, deposits and fouling can build up on the sleeve and interfere with UV transmission.

The 57-SERVKIT-RN includes a new UV57SLEEVE, allowing the lamp and sleeve to be refreshed together as part of the same service.

Why Replace the Filters at the Same Time?

Effective prefiltration helps prepare the water before it enters the UV chamber.

The included filters provide progressive sediment filtration:

20PP10 — 20 Micron Poly Pleated

followed by:

1PS10 — 1 Micron Polyspun

The first cartridge captures larger suspended particles before the second cartridge provides finer 1 micron filtration.

Replacing both cartridges during UV servicing gives the filtration and UV stages a complete refresh at the same time.
