Maintenance and service
Change the air filter (every year or if it is very dirty):
• Turn the instrument off and disconnect the power cord.
• Remove the fitted square air filter from the bottom of the instrument
and replace the dirty filter mat with a new one.
N O T I C E
Check the condition of your air filter (level of dirt) on a regular basis, as a very
dirty filter mat lengthens the cooling-down phase of the thermostat.
