5 Start-Up Operation
5.1 Division 1 Y/Z-Purge Start-Up Operation
1. When the air, signal, and power connections are complete, replace and close all access
doors and covers.
2. Turn the Control valve to PURGE. Look at the Flow Meter on the front panel to verify that
the flow rate is 150 SCFH. If not, readjust the Purge Regulator to set the flow to 150 SCFH.
3. If the Flow Meter does not read 150 SCFH, inspect the enclosure for blockage in the purge
gas lines and take appropriate action to clear the blockage. If blockages are not obvious,
verify that the purge air or inert gas is clean and dry.
4. Slowly turn the Control Valve to OPERATE. If the Control Valve is turned rapidly, the ball
in the Flow Meter may start oscillating. Look at the pressure gauge on the front panel to
be certain that the internal pressure is 1.0” of Water Column. If not, reset the adjustment
on the exhaust assembly on the so that the pressure gauge reads 1.0” of Water Column.
5. Slowly turn the Control Valve to PURGE. Make sure that the Flow Meter reads 150 SCFH.
If not, readjust the regulator for 150 SCFH.
6. The size of your enclosure will determine the purge time, unless you purchased a Y/Z-
Purge on a DAISY Enclosure, then follow the purge time stated on the product label. After
purge cycle, slowly turn the control valve to OPERATE.
7. Apply power to the enclosure. The Pressure Good LED should be illuminated green. If not,
check the internal pressure: it should be between 0.4” and 10.0” of Water Column. The
pressure good led must be illuminated green at this time. If it is not, please consult the
factory.
8. If the Pressure Good LED is not illuminated green, the internal pressure is below 0.4”
Water Column and the Alarm is on. Turn power off to the enclosure and repeat steps 2
though 6.
IMPORTANT!
It is the customer's responsibility to
determine the purge time and mark the
enclosure accordingly
