Preventive maintenance intervals may vary depending on the frequency
of instrument usage.
Inspect the water bath and tubing for algae or other growth. If algae is
present, change the water and add algaecide. Ensure the algaecide is
compatible with PETG and vinyl plastics.
If necessary, drain the water from the water bath and clean it thoroughly.
Refill the bath and add algaecide.
Ammonia, bleach, alcohol, and other solvents can cause
deterioration of the plastic. Use only cleansers approved for plastic
materials. These can be found in the catalogs of most scientific
supply houses. Additionally, do not use abrasive cleansers that may
scratch the plastic.
1 Remove the top cover.
2 Inspect the spindle drive belt for wear, fraying, and tension.
A small dusting of belt material may be found on the motor plate. This
is normal and not a cause for concern.
3 Check that the spring-loaded belt tensioner is maintaining pressure
on the belt and is not loose.
