11. Maintenance and service

Before every usage, check that:
- external cabling is not damaged
- protection glass in front of lamp is not cracked or removed
- protection glass is clean and free from spray fog that
decreases the intensity
Weekly
Check that all IR and UV lamps light up during mobile dryer operation.
Defect IR lamps can cause uneven heat distribution over the surface.
Clean the dryer from dust, which can be a cause of fire, with a damp
cloth. Also, check that all cables are undamaged. A damaged cable
can be a danger to life!
Monthly
Check the gold reflectors. Damaged or extremely dirty reflectors can
over heat the reflector body and/or the cassette. In case of doubt,
please contact the customer service in order to clarify if the gold
coated reflector needs to be changed.
Quarterly
Plan to change the air filter approx. once per year. You will get a
message in the software when it is time to change. When starting up
the dryer you will get an indication on how much of the filter time that
is used.
