Control and maintenance
Weekly
Check each week that all lamps light up when the
mobile dryer is in operation. A damaged lamp can
cause uneven temperature distribution across the
heated area.
Check also that all wires are entirely undamaged.
A damaged wire can result in danger to life!
Monthly
Check the gold reflectors. Damaged or very dirty
gold reflectors can harm the reflector body and/or
the cassette.
Quarterly
At least once per quarter, the air filter should be
replaced. If its outer surface becomes very dirty at
an earlier stage, the filter must be changed imme-
diately.
