Beamz MHL1912 User Manual page 7

The buildup of dust, dirt and other airborne particles will reduce the unit's light output. It will also prevent the unit from cooling correctly, and this will
reduce the unit's lifetime. The rate of dirt buildup will vary depending on environmental factors such as airborne dust, use of smoke machines, airflow
from ventilation systems, etc. The unit's cooling fans will accelerate buildup, and any smoke particles that are present in the atmosphere will increase the
tendency for dirt to clog.
To get the best performance and lifetime from the unit, inspect it regularly and clean it as soon as you see signs of dirt buildup.
Assess the operating environment each time you begin to use the unit. In dusty or smoky conditions, inspect the unit after a few hours and check it
frequently the unit may attract dirt faster than you expect. Draw up a cleaning schedule that will make sure that dirt is removed before it can build up.
Use the following guidelines:
• Disconnect the unit from power and allow it to cool completely before cleaning.
• Do not use solvents, abrasives or any other aggressive product to clean the unit.
• Vacuum or use low-pressure compressed air to remove dust and loose particles from surfaces and air vents. Prevent the blades of cooling fans
from turning before you aim a vacuum or air jet at the fan, or you may spin the fan too fast and damage it.
• Clean glass components by wiping gently with a soft, clean, lint-free cloth moistened with a weak detergent solution. Put the solution on the cloth
and not on the surface to be cleaned. Avoid rubbing glass surfaces.
• Dry the unit with a soft, clean, lint-free cloth or low-pressure compressed air before reapplying power.

from any angle (second code digit). That is why this unit can also be used out‐ doors. Events units are generally only designed for temporary use however
(event lighting) and not for permanent use outdoors. The specified protection class does not make a statement about the weather resistance of the units
(resistance to changing ambient conditions as well as against the effects of sunlight and UV rays). The seals and screw connections of the units must be
checked regularly to ensure a fault-free operation.
This unit is virtually maintenance-free, but you should check the unit regularly for mechanical and electrical aspects.
Assess the operating environment and establish an inspection and cleaning schedule that follows the guidelines below:
• Disconnect the unit from the power supply and allow it to cool completely before inspecting and cleaning.
• Check that the screws and bolts used to install the unit are securely tightened and free from corrosion.
• Check the housing, fixing points and installation points, they must not show any signs of deformation, wear or fatigue.
• Check the mechanically moving parts, these must not show any signs of wear or fatigue.
Check the electrical power and signal cables, they must not show any damage or fatigue.
•
Do not use solvents, abrasives or other aggressive products to clean the unit.
