10. ROUTINE MAINTENANCE
The MAX 5000XL requires routine cleaning to keep the test chamber free of excess
sample material. Failure to keep the instrument interior clean reduces its accuracy
and repeatability. Sample material collecting in the test chamber prevents free
movement of the pan support. In addition, sample material collecting on the rim of
the heater shroud prevents the lid from closing completely, causing erratic results.
Material may fall into the system's interior, causing balance problems. Routine
cleaning of the test chamber reduces the likelihood of problems and repairs,
extending the life of the instrument.
10.1. Chamber Interior
The chamber interior should be cleaned when needed to eliminate the buildup of sample
material. To clean debris from the chamber’s
interior:
Switch the main power switch OFF.
Use a vacuum line, portable vacuum
cleaner, or a small paintbrush to remove
debris from the area around the balance
cover and pan support stem.
A compressed air line or canned air is not recommended since
debris migrates into the system's interior and settles in the
electronic components and balance stem.
Do not clean the shroud or heater element with a brush, vacuum,
cleaner liquid, or any object. Use the “Oven Chamber Cleaning”
procedure.
