10. MAINTENANCE AND CLEANING
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 con-
nected 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 (e.g. material abrading or damages) and must not rotate with unbalances.
4) The electric power supply cables must not show any damages, material fatigue (e.g.
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 re-
moved.
DANGER TO LIFE!
Disconnect from power supply before starting
maintenance operation!
It is absolutely essential that the fixture is kept clean and that dust, dirt and smoke-fluid
residues must not build up on or within the fixture. Otherwise, the fixture‘s light-output will
be significantly reduced. Regular cleaning will not only ensure the maximum light-output,
but will also allow the fixture to function reliably throughout its life.
Please use a moist, lint-free cloth. Never use alcohol or solvents!
The objective lens will require weekly cleaning as smoke -fluid tends to building up res i-
dues, reducing the light-output very quickly. The cooling-fans should be cleaned monthly.
The gobos may be cleaned with a soft brush. The interior of the fixture should be cleaned
at least annually using a vacuum -cleaner or an air-jet.
The dichroic colour, the gobo-wheel and the internal lenses should be cleaned monthly.
To ensure a proper function of the gobo-wheel, we recommend lubrication in six month
intervals. The quantity of oil must not be excessive in order to avoid that oil runs out when
the gobo-wheel rotates.
There are no serviceable parts inside the device except for the lamp and the fuse. Mainte-
nance and service operations are only to be carried out by authorized dealers.
Please refer to the instructions under "Installing/Replacing the lamp".
