2.4.2.3 BOOSTER HIGH PRESSURE INSTRUMENT GAS SUPPLY
CONNECTION
Connect a high pressure gas supply to the gas booster high pressure IN port.
The IN port is a 1/4 in. NPT F fitting on the high pressure gas filter. Use a thread
sealer to seal the connection. The high pressure gas supply should not exceed
3 000 psi (200 MPa). See Section 2.3.2.2 for additional information on high
pressure gas supply requirements.
Pressure present at the High Pressure IN port will be present at the high
pressure OUT port. Do not supply pressure to the high pressure IN port unless you
are prepared for an equivalent pressure to be supplied to the high pressure OUT port.
2.4.2.4 BOOSTER HIGH PRESSURE OUTPUT CONNECTION
If the GB-152-AF is part of a PGC-10000-AF Pneumatic Gauge Calibration
System, the booster high pressure
OUT port is connected to a GPC1-10000-AF
Gas Pressure Controller SUPPLY port (see the GPC1-10000-AF Operation and
Maintenance Manual). The GB-152-AF includes an interconnection kit with
fittings necessary to connect the high pressure
OUT port to a GPC1.
To connect the GB-152-AF high pressure OUT port to the GCP1 SUPPLY port ,
proceed as follows:
n
Remove the orange plastic dummy plug from the DH500 fitting in the GB-152
OUT port. Retain the collar that is on the plug.
Remove the orange plastic dummy plug from the DH500 fitting in the
GPC1-10000-AF
SUPPLY port.
Refer to Figure 5. Use the tubing and fittings supplied in the GB-152-AF
interconnections kit (see Table 1):
•
Connect the DH500 2.75 in. (70 mm) nipple to the DH500 elbow.
•
Connect the DH500 6 in. (152 mm) nipple to the DH500 union.
•
Connect the union/6 in. nipple assembly to the open connection on the
elbow/2.75 in nipple assembly.
•
Connect the 2.75 in. nipple end of the just completed assembly to the
GPC1 SUPPLY port.
•
Connect the 60 in. (1524 mm) x 1/8 in. nipple with DH500 tips to the
open connection on the DH500 union of the assembly that is already
connected to the GPC1.
•
Connect the other end of the 60 in. x 1/8 nipple to the high pressure OUT
port of the GB-152-AF.
Test that all fittings tightened before applying pressure.
