Troubleshooting - Dometic ACC3100D Instructions Manual

Allow the solar panels to cool down before cleaning to avoid burns or damage to the solar panels as a
result of excessive temperature differences. Clean the solar panels in the early morning or late afternoon
hours when the sunlight is low and the solar panels are cooler.
NOTICE! Damage hazard
• Do not clean the solar system with a high-pressure cleaner.
• Do not use sharp or hard objects, abrasive cleaning agents or bleach during cleaning as these can
damage the device.
Regularly check live cables for insulation faults, breaks, rodent damage and weathering.
Regularly check that all connections are tight and corrosion free.
Regularly check the surface of the solar panels for cracks and missing or defective components.
For maximum performance keep the solar panels free of dirt and shading, e.g. dust and leaves. Clean the solar
panels with a so, damp cloth or sponge.
Regularly remove accumulated dirt near the solar panels.
Occasionally check the sealing of the roof duct for any damage.
