1-10 | IPS-4 Dual Bench (UV / IR) Analyzer
The analyzer must be installed and operated in accordance with this
instruction manual. Instrument air or nitrogen may be used as the purge
gas.
Once the analyzer has been located in an area contaminated with
flammable gases or vapors the IPS-4 purge system must be activated
to keep these gases out of the enclosure. For this reason, AC power and
an instrument air supply must be connected to the IPS-4. See “Sys-
tem Start-Up” for instructions on how to initialize the purge system.
If it is not required that the IPS-4 be powered on at this time, switch-
ing the power off at the power source will shut down the analyzer
while maintaining the protective internal pressure. Switching the
power on again will re-activate the IPS-4 if the purge controller is
still in the normal pressurization mode.
For the protection system to operate properly, the cover on the dis-
connect enclosure must be properly installed and the electronics and
oven enclosure doors must be securely shut. All door latches must be
properly tightened with the key.
