Cleaning and maintenance
The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a skilled
person once a year.
The following points have to be considered during the inspection:
1). All screws used for installing the devices or parts of the device have to be tightly connected and must not
be corroded.
2).There must not be any deformations on housings, fixations and installation spots(ceiling,
suspension,trussing).
3).Mechanically moved parts like axles,eyes and others must not show any traces of wearing(eg: material
abrading or damages)and must not rotate with unbalances.
4).The electric power supply cables must not show any damages,material fatigue(eg: porous cables) or
sediments. Further instructions depending on the installation spot and usage have to be adhered by a skilled
installer and any safety problems have to be removed.
We recommend a frequent cleaning of the device. Please use a moist, lint-free cloth. Never use alcohol or
solvents!
The cooling-fan should be cleaned monthly.
The interior of the fixture should be cleaned at least annually using a vacuum-cleaner or an air-jet.
There are no serviceable parts inside the device. Maintenance and service operations are only to be carried out
by authorized dealers.
