Monthly
Check LEDs and display
Check the LEDs and displays are legible on the receiver and transmitter units. Clean
them if necessary.
Three-monthly
Check purge flow rates
Use the flow meters on the purge panel to check the purge flow rates are the same
as at the time of commissioning.
Leak check the purge fittings.
8.5 Alignment / purging flanges
Do not disconnect the pipes from the alignment / purging flanges if there
is a risk to personnel or the environment from exposure to the potentially
hazardous gases contained in the process being monitored.
Failure of the purge will severely damage the optical surfaces of the
Laser 3 Plus.
Test the alignment / purging flanges for leaks at regular intervals as required for the
specific process and installation conditions.
Inspect the pressure of the flange and window purge at regular intervals to ensure it
is higher than that of the process as required for the specific process and installation
conditions.
8.6 Enclosure purge and breather (if fitted)
Check the flow rates of the purge panel at regular intervals to ensure it is operating
correctly.
Inspect the breather (if fitted) at regular intervals to ensure it has not become
blocked or otherwise damaged.
8.7 User replaceable spare parts
There are no user replaceable spare parts.
All Laser 3 Plus returned to Servomex or one of its appointed agents for servicing,
disposal, or any other purpose must be accompanied by a completed
decontamination certificate.
