LED should illuminate YELLOW, indicating that it is purging.
IF THE INDICATOR DOES NOT ILLUMINATE a thorough inspection for leakage of
the unit must be made. Panel gaskets can be checked with a soap solution. If
leaks are not visually apparent, verify that the pressurized air is clean, dry and is
40 PSI at the inlet.
DO NOT ATTEMPT TO OPEN THE ENCLOSURE WHILE IT IS PRESSURIZED!
OPENING PRESSURIZED ENCLOSURE CAN RESULT IN SERIOUS INJURY!
6. If the Pre-installation Test (Section 3) was completed successfully and the same results
were seen up to this point in the procedure, you may skip the remaining steps of this
procedure. If not, continue to Step Error! Reference source not found.
7. Slowly increase air pressure with the regulator until the purge process stops.

8. Remove AC power from the enclosure for a minimum of 30 seconds. Decrease
the pressure reading on the pressure gauge by 5 PSI.
This change may vary slightly on some units; if in later testing the unit fails with

9. Re-apply AC power. The Purge Status LED will illuminate yellow and should purge
for a minimum of 8 minutes. Time will vary according to the flow rate of the air
into the enclosure.
10. After the purge is complete, the Purge Status indicator will illuminate green.
AC power is now applied to the internal electronics to power on the display or PC.
