Maintenance; Factory Default Settings - Lab.gruppen PLM series Operation Manual

11.2 Maintenance

During normal operation your PLM will provide trouble-free service. The main user maintenance is to
periodically clean the dust filters behind the front grilles. The two grilles can be removed by undoing the
knurled-head screws, and the foam filter elements then withdrawn. They are best cleaned with a hand-held
vacuum cleaner.
If the LCD display needs cleaning, use a soft cloth only. Do NOT use solvent cleaners of any kind as they
may attack the plastic.
In some extreme cases it may be necessary to clean the inside of the PLM. This procedure should only be
carried out by qualified service personnel. This may be necessary if the PLM has had prolonged operation
in an extreme environment such as one where "cracked oil" smoke machines are in use. If you are using
your PLM in such a heavy duty application, it is recommended to have it serviced every 3 years as a purely
preventative measure
