If installed location has a positive pressure the air-purge system must be used continuously
during installation to prevent process gases from contaminating optical surfaces or over
heating instrument electronics. If the system is shut off for more than momentary
interruptions, the instrument may be damaged. Failure to provide continuous air-purge may
void the warranty.
