WARNINGS
1. BEFORE CONNECTING/DISCONNECTING PRESSURE COUPLINGS,
RELEASE THE PRESSURE AND VENT THE PIPES.
2. ONLY USE CORRECTLY RATED PRESSURE PIPES AND FITTINGS.
2.4.1 Procedure (Figure 2-1)
Make sure that the supply source complies with the specification.
Make sure the supply pressure is isolated from the supply source pipe. It
is recommended that an isolation valve and a 40 micron filter are fitted
between the supply pressure and the instrument as shown below.
Connect the supply pressure to the source port, fitting a bonded seal
between the pressure union and the port. All ports use a G 1/8 thread,
except the
reference port (M5). Make sure that each coupling is tight.
Fit the outlet pipe to either the front or rear outlet port, using a bonded seal.
Fit a blanking plug and bonded seal to the unused port.
