11. Maintenance and Cleaning
The following points have to be considered during the inspection:
1. All screws 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
the housing, color lenses, fixations and installation spots (ceiling, suspension,
trussing). 3. Mechanically moved parts must not show any traces of wearing and
must not rotate with unbalances. 4. The electric power supply cables must not
show any damage, material fatigue 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.
In order to make the lights in good condition and extend the life time, we suggest a
regular cleaning to the lights. 1) Clean the inside and outside lens each week to
avoid the weakness of the lights due to accumulation of dust. 2) Clean the fan
each week. 3) A detailed electric check by approved electrical engineer each
three month, make sure that the circuit contacts are in good condition, prevent
the poor contact of circuit from overheating.
We recommend a frequent cleaning of the device. Please use a moist, lint- free
cloth. Never use alcohol or solvents. There are no serviceable parts inside the
device. Please refer to the instructions under “Installation instructions”. Should you
need any spare parts, please order genuine parts from your local dealer.
