Keep temperature within limits described in product specification
Make sure treated surface will not be shadowed by other objects
Make sure treated surface is dust free
Make sure lamp (UVC source) is clean and free of dust
Make sure distance and irradiance level are fit correctly for a
disinfection purpose. Irradiance decreases with square of distance
(e.g. 2x longer distance results in 4x lower irradiance)
Make sure lamp is replaced by Philips and with frequency in
accordance to lamp specification
Connect luminaire according to manual instruction
Switch on luminaire with all safety measure described in user
manual
