Maintenance and service

Weekly
Check that all IR lamps light up during mobile dryer opera-
tion. 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 reflec-
tors 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.
Yearly
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.
