Replacing components on an installed appliance

ESV have foreseen the circumstances where an original component found in a certified appliance would no longer be available and have drafted the following that takes into account these situations.

Any replacement component must be as per the original (like for like) or a non original replacement component must provide equal or better safety than the original.

Conditions to consider are:

The original Certification or acceptance of an appliance may be compromised if a replacement safety component is not verified as having an equivalent or better safety performance.

The installer of the replacement component must check with the manufacturer of the appliance or the replacement component manufacturer/supplier for suitability in the application.

Where the manufacturer of the replacement component has provided a list of suitable applications where the component can be used and a fault transpires with the replacement component or the appliance in the application that is attributed to the replacement component the responsibility for any consequence will remain with the manufacturer of the replacement component.

For a Type B appliance the replacement of a safety related component that is not a direct “like for like replacement requires you make a submission to ESV.
