The following steps and diagram indicate the location of the
connection points required to measure the manifold pressure.
The manifold pressure may be measured using a U-Tube Manometer
or a Differential Pressure Gauge. The diagram shows the connection
of both measuring devices. Only ONE DEVICE IS REQUIRED to
measure the manifold pressure.
Remove the plug. Install the appropriate barbed fitting and connect
the pressure side line from the U-Tube Manometer or Differential
Pressure Gauge.
