Warranty

The output of a UV system is essentially determined by the optical components in the system, the UV lamp and the reflectors. IST METZ has always been aware of the key role of these components, and therefore focusses on consequent in-house development and production. Only by doing so can we meet the high demands of our customers.

In the case of IST UV lamps the high technical standard of the products is achieved by craftsmanship in connection with extensive quality controls. Therefore IST Metz is able to offer outstanding warranties on these product.

These warranty conditions apply on condition that the following requirements/duties of the customer are met: 

• Proper storage of the IST UV lamps
• Correct installation and commissioning of the IST UV unit
• Regular maintenance of the IST UV unit in accordance with the operating manual
• Regular cleaning of the IST UV lamps in accordance with the operating manual
• A reduction in drying power caused by external dirt accumulation is not recognised as a reason for rejection
• A reduction in the UV radiant power to 75% of the original value in the UV range in question during the warranty period is not recognised as a reason for rejection
• Before installation of a new UV lamp, the FLC contacts must be examined and must be in good condition

WARRANTY CONDITIONS

Mercury vapour lamps must not be disposed of in bulky or residual waste, as mercury can be released into the environment during incineration or landfill. Instead, they should be handed over to specialised recycling facilities that safely collect and recycle the mercury. As 99.8 % of mercury can be recycled, the actual consumption is minimal, provided the lamps are disposed of properly. Used UV lamps can be returned to IST METZ GmbH & Co. KG for disposal. 

Excimer lamps from eta plus do not contain any hazardous substances, in particular no mercury, and can therefore be disposed of with household waste. Nevertheless, eta plus asks you to return used lamps for analysis and product improvement.

We also offer the disposal of third-party lamps for a fee. For enquiries, please send an e-mail to parts@ist-uv.com
