Griven GRAPH-i-LINE 20 [25/28] Thermal protection

An internal temperature sensor prevents the unit from overheating. The temperature sensor will limit the current

to leds, protecting their integrity, if the ambient temperature exceeds the one allowed.

To ensure maximum functionality and light output it is recommended to follow these instructions:

7.1 Cleaning the unit

The unit must be cleaned regularly. Cleaning regularity will depend especially on the environment where the unit

will operate: deposits of dust, smokes or other wastes will reduce the light output performances.

• Clean regularly the glass of the unit.

• Be careful when cleaning the components. Operate in a clean, properly illuminated environment.

• Do not use solvents which could damage painted surfaces.

• Remove left particles by a cotton towel dampened with a glass-cleaning liquid or distilled water.

• Remove smoke and other wastes by a cotton towel dampened with isopropyl alcohol.

• Dry out by a clean, soft, non-scratching towel or by compressed air.

7.2 Regular checks

• Check electrical connections, especially the ground wiring and the power supply cable.

• Check that the unit is not damaged mechanically. Replace those components which have got deteriorated.
