Installation Process
If the indicators are not the correct color, recheck the input pressure
and flow to be sure the pressure is in the appropriate range.
If the inlet pressure and flow is correct, but the indicator colors are not
correct, contact technical support.
9. Move the lever on the MiniPurge panel to the Purge Off position.
10. Open (turn counter-clockwise) the leakage compensation valve on
the front of the purge system until the alarm/pressurized indicator
turns green. Then slowly close (turn clockwise) the leakage
compensation valve until the alarm/pressurized indicator turns red.
Note the pressure on the gauge just before the indicator turns red and
compare it to the minimum pressure specification on the purge system
label. The pressure should be at or above the minimum pressure listed
in the specification.
11. Open (turn counter-clockwise) the leakage compensation valve
until the relief valve on the side of the enclosure opens.
The system purging indicator will turn yellow and stay on. You will
hear the valve open and gas flowing through the valve.
12. Check the pressure gauge or water manometer to be sure that the
relief valve opened at or below the maximum pressure indicated on
the system purge label.
Tolerances of 2 mbarg, 0.8 in H
2
O, and 200 Pa are acceptable. If the
purge system is not operating within these tolerance specifications,
contact Thermo Fisher Scientific technical support.
