We recommend you service your VeriVide equipment at least once every 12 months, to ensure it is in the same condition as when it was purchased. The 12 month interval also maintains the parts warranty.
Most international, national and retailer standards require your VeriVide equipment to be serviced before the annual standard audit, to ensure conformance.
However if you reach 2000 hours use of any of the fluorescent lamps within 12 months, you will need to service at this point, to prevent further deterioration in the light quality. Likewise you may wish to service more often if the grey interior is contaminated or dirty.
