7 Maintenance
The total pressure gauge and controller TPG 300 requires no
maintenance. For maintenance of the gauges, refer to the re-
spective documents [4] ... [10].
Turn the unit off and remove all cables (the mains cable
last) before doing any of the work described below.
For cleaning the outside of the unit, a slightly humid cloth will
usually do. Do not use under any circumstances an aggressive or
scouring leaning agent. No water must get into the unit! Before
putting the unit into operation again, allow it to dry thoroughly.
In a very dusty environment, the dust inside the unit
should be periodically removed. Carefully remove the dust
with dry compressed air.
