8 | Maintenance, Cleaning and Repair
42 SkyPanel X Operating Manual
ARRI applies the strictest possible calibration procedures. ARRI uses the best quality materials
available to ensure optimum performance and the longest possible component lifetimes. However,
optical components are subject to wear and tear over the life of the product. They result in gradual
changes in color over many thousands of hours of use. The extent of wear and tear depends heavily
on operating conditions and environment. It is impossible to specify precisely whether and to what
extent performance will be affected.
However, you may eventually need to replace optical components if their characteristics are affected
by wear and tear after an extended period of use and if you require luminaires to perform within very
precise optical and color parameters.
8.2 Cleaning
Regular cleaning is very important for device life and performance. Buildup of dust, dirt, smoke
particles, fog fluid residues, etc. degrades the light output and cooling ability.
Cleaning schedules vary greatly. They depend on the operating environment. It is therefore
impossible to specify precise cleaning intervals for the device.
Cooling fans suck in airborne dust and smoke particles.
Use in aggressive operation environment (e.g. at the seaside, on ships, near salt water, on industrial
plants) may cause corrosion and degrade optical components if not kept clean.
In extreme cases the device needs cleaning after surprisingly few hours of operation.
Environmental factors that may require frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Airborne dust (from stage effects, building structures and fittings or the natural environment at
outdoor locations, for example).
If one or more of these factors is present, inspect the device within its first few hours of operation to
see whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you
to assess cleaning requirements in your particular situation. If in doubt, consult a certified ARRI
service center about a suitable maintenance schedule.
ARRI IP 66 rated devices are designed to resist water and moisture in environments with widely
varying climate, temperature and humidity conditions. If devices are not managed correctly during
installation and service, water and moisture can enter. This causes humidity and condensation
inside the device. Follow the precautions below to avoid this problem.
General
Air, and even water, can be sucked through connectors into the device. A cracked or porous
protective cap or connected cable can allow water into the device. Replace any protective cap or
cable that is not in perfect condition. Make sure that connected cables from the device open into dry
areas (e.g. junction boxes in dry locations).
Cleaning
Do not clean the device with high-pressure water jets. Do not immerse the device. Do not use
cleaning agents that contain solvents, abrasives or caustic agents for cleaning, as they can cause
surface damage to the device. The aluminum housing and front glass can be cleaned with mild
detergents such as those for washing cars.
To clean the housing and front glass:
1. Visually check that the silicone seals and the protective caps for the data and power connectors
are in good condition and in place (except the LEMO connector which does not need a
protective cap as it is IP 69 rated). If any seal or cap shows signs of damage, cracking or loss of
water resistance, stop cleaning the device and contact a certified ARRI service center.
2. If seals are in good condition, rinse off loose dirt with a hose or low-pressure water spray. The IP
66 rating allows clear, cold water jets up to 100 l per minute with a 2.5 mm nozzle in any
direction.
3. Wash the aluminum housing and front glass using warm water with a little mild detergent and a
soft brush or sponge. Do not use abrasive cleaners.
4. Rinse with clean water and wipe dry.
