shuts down the fixture. The fixture will not function normally again until the temperature has fallen to a

Maintaining IP66 protection
The fixture is supplied as a sealed unit. It may be opened for the purposes of changing effects
modules or installing power and data cables by a qualified technician in a dry, dust-free environment.
Condensation and pressure relief valve
A valve with a gas-permeable membrane in the base of the product equalizes pressure by allowing air
to pass through it when the product heats up and cools down, but at the same time it acts as a barrier
to water in liquid form. This valve requires maintenance – see 'Pressure relief valve' on page 75 for
details.
Under certain conditions, condensation may become visible under optical components. This is normal
and harmless. The fixture gradually expels condensation via its pressure relief valve.
