UV Spares

UV Spares

Model-matched UVC lamps, quartz sleeves, seals and service parts

UVC spares are not interchangeable just because wattage or length appears similar. Lamp bases, electrical ballasts, quartz dimensions, end seals and production generations must match the exact unit.

Record the manufacturer, full model name, wattage, SKU and any serial or production code. Isolate electricity and water before servicing, allow the lamp to cool and follow the manual to protect the fragile quartz and seals.

Identify the exact UVC before selecting a spare

• Use the model label and parts diagram.
• Match lamp base, wattage and electrical type.
• Match quartz length, diameter and end design.
• Renew seals where the manual requires it.
• Leak-test before restoring electrical power.

Our practical view: UV spares must match the exact make, model and wattage. We verify the label and physical part before supplying a lamp, quartz sleeve, seal or connector because a near match may fit badly or be unsafe.

UV Spares Selection and Maintenance Guide

Wattage alone is not a part number

Different UVC systems can use electrically or physically incompatible lamps at the same nominal wattage.

Quartz and seals work as a set

A correct sleeve can still leak if O-rings are wrong, twisted, dirty or compressed incorrectly.

Safe recommissioning needs two checks

Confirm the water side is leak-free before energising the lamp and never operate with covers or interlocks defeated.

UV Spares Frequently Asked Questions

These answers provide general selection and maintenance guidance. Follow the exact UVC manual and never expose eyes or skin to an illuminated UVC lamp.

How do I identify the correct UV spare?

Use the full UVC model, wattage, SKU, serial or generation and the manufacturer parts diagram.

Are UV bulbs interchangeable by wattage?

No. Base, length, ballast and lamp technology must all match.

Should UVC O-rings be replaced during servicing?

Follow the manual; replace damaged, hardened or model-specified seals with the correct part.

Can I use a generic quartz sleeve?

Only when dimensions, material, ends and seals are explicitly confirmed for the exact unit.

Why is my UVC leaking after a bulb change?

Possible causes include a damaged sleeve, displaced or contaminated seal, incorrect assembly or uneven tightening.

Can I test a UV bulb outside the housing?

No. Never expose eyes or skin to an illuminated UVC lamp; use the units safe viewing indicator.

How should I handle a replacement UV lamp?

Isolate power, let it cool, avoid touching the glass with bare fingers where instructed and follow disposal guidance.

How should old UV lamps be disposed of?

Follow local rules and the lamp manufacturers guidance; many lamps require specialist recycling and must not be broken.

Should I keep a spare UV bulb?

It can reduce downtime, but store it safely in original packaging and observe shelf and handling guidance.

Can a dirty quartz sleeve mimic a failed bulb?

Yes. Deposits can block UVC transmission even when the lamp is operating.

Do replacement parts affect the warranty?

Use parts and procedures accepted by the manufacturer and retain proof of service where required.

What should I inspect when the UVC is open?

Check the sleeve, seals, lamp holder, cable, housing and deposits without bypassing safety features.

Can I replace a UVC ballast myself?

Only if the unit design, warranty and electrical competence requirements allow it; otherwise use an authorised service route.

How do I recommission a serviced UVC?

Reassemble to the manual, restore water flow and check for leaks before applying electrical power.

Why should I record the installation date of a lamp?

It provides an accurate operating-age reference for scheduled replacement.
