Turn off external switches and circuit breakers when working with the top cover (or front
door) of the product open.
• Purge not only inside of IR800G/IR810G but all measuring gas lines with zero gas

6.1 Daily check and maintenance procedures
n
Periodic maintenance
The front window should be kept clean to ensure clear visibility of the screen and proper
operation of the touch panel. If dirty, wipe clean with a soft damp cloth or soft tissue. For more
stubborn stains, use a mild detergent.
Ensure that the case remains watertight against water and vapor. Make sure the sealing area is
clean and properly fitted when opening the front door to remove the cable gland and put it back in
place.
CAUTION
Never use strong chemicals or solvents. If the window is heavily soiled or scratched, parts may
have to be replaced. Please consult Yokogawa for service.
