Low Pressure Alarm Switch and drain-
age of the pilot line condensate should
be performed quarterly as follows.
1. Close the Diaphragm ChamberSup-
ply Control Valve.
2. Close the Main Control Valve.
3. Open the Main Drain Valve.
4. Drain the dry pilot line condensate
as follows.
a. Close the Gauge Test Valve lo-
cated below the Dry Pilot Line
Pressure Gauge.
b. Remove the 1/4" Plug from the
Gauge Test Valve.
c. Crack Open the Gauge Test
Valve and allow all conden-
sate, if any, to drain out.
d. Close the Gauge Test Valve,
replace the Plug, and then
open the Gauge Test Valve.
5. Open the Inspector’s Test Connec-
tion, and slowly relieve pneumatic
pressure. Verify that the Low pres-
sure Alarm Switch is operational and
that the low pressure set points are
as follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar)
below the minimum pilot line
service pressure requirement
shown in Graph C.
• Fire alarm setting at approxi-
mately 15 psi (1,0 bar) below
the minimum pilot line service
pressure requirement shown
in Graph C.
6. Close the Inspector’s Test Connec-
tion, and allow the Dry Pilot Line to
automatically repressurize.
7. Open the Diaphragm Chamber Sup-
ply Control Valve.
8. Slowly open the Main Control Valve.
Close the Main Drain Valve as soon
as water discharges from the drain
connection. Observe the Automatic
Drain Valve for leaks. If there are
leaks, determine/correct the cause
of the leakage problem. If there are
no leaks, fully open the Main Control
Valve.
