1. An Armstrong Liquid Drainer
is recommended to drain
liquid from the air supply line
to the panel.
2. An Armstrong AF-10 filter
with a 5 micro filter should be
installed in the air line going
to the A-panel to reduce the
chance of dirt fouling the
instrumentation regulator.

Install the Control Panel A in
a location that is accessible for
maintenance.
Install the Control Panel A
making sure the shop air is
connected to the automatic
drain on the back of the panel.
Connect the air line from the
bottom of the regulator (out)
on the back of the panel to the
top of the air loaded pressure
reducing valve or control

Open the valve on the drip leg
to allow the liquid drainer to
drain any liquid at the inlet of
Control Panel A.
Open the l/4” ball valve to the
filter and Control Panel A.
Using the Panel Regulator
Knob (R) on the front of the
panel, set the air loading
pressure to the PRV.
Open the valve slowly on the
outlet side of the PRV and
also on the sensing line.
Open the inlet valve to the
PRV slowly to avoid water
hammer and potential
diaphragm damage.
Adjust the air loading pressure
until the desired outlet
pressure is achieved on the
Delivery Pressure Gauge (A).
After the entire system
stabilizes, adjust again if
required.
