Warnings:

• Always disconnect power before performing any work on the UV system.
• Always shut-off water flow and release water pressure before servicing.
• Regularly inspect your UV system to ensure that the power indicators are on and no alarms are present.
• Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum performance.
• Always drain the chamber when closing a seasonal home or leaving the unit in an area subject to freezing temperatures.

Aquafine #250449-DS20 Replacement Lamp Customer Questions & Answers

No customer questions have been submitted for this. Have a question? Ask it above.

It is critical that only genuine Trojan Aquafine brand original equipment lamps be used in your Aquafine system. It has come to our attention that a number of Chinese manufacturers are making knock-off replica UV lamps. While they may physically fit in an Aquafine system, they are NOT compatible. Testing of a wide range of these lamps has shown that many do not provide a safe UV dose or offer protection for the stated lamp life, and in some cases have even caused the failure of the ballast/controller and melting of the lamp harness.

The use of Non-Genuine lamps will void safety certifications (UL, CSA etc.) and damage other system components such as connectors, lamp plugs and ballasts leading to even higher operations and maintenance costs and increased maintenance. We only sell Genuine OEM replacement parts.
