SITRANS LU SAM – INSTRUCTION MANUAL

7ML19985CF02

Maintenance

The SITRANS LU SAM requires no maintenance. However, a program of periodic checks 
is recommended. This should include regular inspection, general cleaning and good 
housekeeping practices. 

The enclosure and circuit boards should be cleaned only when power is disconnected at 
the main breaker, using a vacuum and clean, dry paint brush. Check all electrical 
terminals for corrosion and arcing.
