INSTALLATION AND SETUP
2.3.1
INSTALLATION CONSIDERATIONS
Installation of the GB-H-152 depends on the specific application. For a detailed description
of the theory of operation see Section 3.1. Refer to Section 2.3 before attempting installation.
A variety of factors must be considered when determining where to locate the GB-H-152.
Factors include, but are not limited to:
•
the high pressure being generated and associated safety concerns
•
the source of gas supplies (drive air supply and high pressure instrument gas supply)
•
noise
level
•
exhaust of drive air out of the muffler
•
vibration during use
•
access to the unit for operation of the regulators and valve
•
point of use of output pressures
2.3.2
INSTALLATION
To install the GB-H-152, follow the steps below (numerical references refer to Figure 2):
n
Place the GB-H-152 in the desired location.
o
Close both regulators (2) and (6) by rotating the knobs counter-clockwise until no spring
force is felt.
The drive adjust (2) and high pressure adjust (6) regulators have a stop that prevents
continued counter-clockwise rotation.
The drive adjust regulator (2) has a locking mechanism to prevent accidental adjustment.
To unlock, pull the knob up.
p
Close the booster drive shutoff valve (4).
q
Connect shop drive air supply to the 1/4 in. NPT F
DRIVE IN
port using tubing of
appropriate pressure rating.
Maximum input pressure to the booster drive adjust regulator (2) is 1.7 MPa (250 psig).
Pressures above this level may result in a failure that could damage the instrument and/or cause
personal injury. Using connecting tubing rated for working pressures below 1.7 MPa (250 psig) is
not recommended.
r
Connect the test gas supply to the 1/8 in. NPT F
SUPPLY IN
port (6) using tubing of
appropriate pressure rating.
Maximum input pressure to the SUPPLY IN port (5) is 40 MPa (6 000 psig). Pressure above
this level may result in a failure that could damage the instrument and/or cause personal injury.
