Genuine Davey MC-SERVKIT-RN UV Service Kit – Lamp, Sleeve & Filters

Keep your Davey Microlene UV water treatment system serviced with the Genuine Davey MC-SERVKIT-RN UV Service Kit.

This complete maintenance kit brings together the key replacement components required for a routine service, including the UV lamp, quartz sleeve, O-rings and two replacement water filter cartridges.

Rather than purchasing the UV and filtration components separately, the MC-SERVKIT-RN provides a convenient all-in-one service kit specifically matched to compatible Davey systems.

What's Included

The MC-SERVKIT-RN includes:

• 1 × MC-HOLP — UV replacement lamp
• 1 × MC-HOSL — UV sleeve
• 2 × O-rings — for the lamp/sleeve assembly
• 1 × 20PP20 — 20 Micron Poly Pleated Water Filter Cartridge
• 1 × 1PS20 — 1 Micron Polyspun Water Filter Cartridge

Everything is supplied together as a Genuine Davey service kit.

Compatible Davey Systems

The MC-SERVKIT-RN suits:

• MCS
• MCXS
• AQS-S
• AQS-XS
• AQS-S-KT
• AQS-SXS-KT

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 more than just the UV lamp.

The filtration stages prepare the water before UV treatment, while the lamp and sleeve work together in the UV chamber.

The MC-SERVKIT-RN allows these key service components to be replaced together, helping keep the complete filtration and UV treatment process maintained.

Complete Service in One Kit

Instead of identifying and ordering each service component separately, you receive the matched:

20 Micron Pleated → 1 Micron Polyspun → UV Treatment

along with the replacement UV sleeve and O-rings.

Genuine Davey Components

The MC-SERVKIT-RN is a Genuine Davey service kit, providing the correct matched replacement components for compatible Davey systems.

Filtration + UV Maintenance

This isn't simply a replacement lamp.

The kit services both the water filtration stages and UV treatment components, making it a practical choice for scheduled system maintenance.

How the Filtration Stages Work

Stage 1 — 20PP20 20 Micron Poly Pleated Filter

The first filtration stage uses the 20PP20 20 micron poly pleated cartridge.

This stage captures larger suspended sediment and particles before the water moves into the finer filtration stage.

Pleated media provides a large filtration surface area for effective sediment capture.

Stage 2 — 1PS20 1 Micron Polyspun Filter

Water then passes through the 1PS20 1 micron polyspun cartridge.

The finer 1 micron filtration captures smaller suspended particles that pass through the first-stage pleated 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 filtration, the UV system provides the microbiological treatment stage.

The MC-HOLP replacement UV lamp sits inside the UV chamber and works with the MC-HOSL sleeve.

The quartz sleeve creates a barrier between the lamp and the water while allowing UV light to pass through into the treatment chamber.

Replacing the lamp and sleeve as part of the service helps ensure the UV stage is properly maintained.

Installation

The MC-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 20PP20 20 micron pleated cartridge in the appropriate first-stage housing.
7. Install the new 1PS20 1 micron polyspun cartridge in the appropriate second-stage housing.
8. Carefully remove the existing UV lamp.
9. Remove the existing sleeve as required.
10. Install the new MC-HOSL sleeve and supplied O-rings.
11. Carefully install the new MC-HOLP UV lamp.
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 sleeve should also be handled carefully, as it is a fragile component.

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

Why Replace the Sleeve?

The UV sleeve plays an important role in the treatment system.

It separates the UV lamp from the water while allowing UV light to pass through into the treatment chamber.

Over time, deposits or fouling can build up on a sleeve and reduce UV transmission. Replacing the sleeve during a major service provides a fresh, clean surface for the UV treatment stage.

The MC-SERVKIT-RN includes a new MC-HOSL sleeve, allowing both the lamp and sleeve to be serviced together.

Why Replace the Filters at the Same Time?

The sediment filters are an important part of the overall treatment process.

Suspended particles can affect water clarity before it reaches the UV chamber. The included filters progressively remove sediment using:

20PP20 — 20 Micron Pleated

followed by:

1PS20 — 1 Micron Polyspun

Replacing these cartridges while servicing the UV components gives the system a complete filtration and UV refresh.
