4.0 Care and Cleaning
The T-Stat LLC should provide years of uninterrupted service. Minimal preventive maintenance is
required. However; it is important to make sure that the T-Stat is kept free of dust. A dusty T-Stat will
not allow air to circulate properly around the built-in temperature sensor effecting proper operation of
the unit.
Ensure temperature
probe in this air tunnel
is free of dirt and dust.
