3.0 INSTALLATION
3.1 Panel Mounting:
Section 8 of this manual shows an outline drawing detailing panel cutout for a standard Hastings CVT Gauge. Install the
meter on the panel using the supplied hardware.
3.2 Gauge Tube Installation:
Situate the gauge tube in a clean, dry vacuum system with the open end pointing down so as to be self-draining should any
vapors condense in it (see Section 6.0). Screw metal tubes into 1/8" female NPT threads using a suitable sealant; Teflon
tape is recommended, or use Hastings Quick Connect O-ring seals for a vacuum tight installation. Do not use Quick
Connect if tube will see pressures greater than ATM.
For information on Hastings Installation Accessories, refer to Product Bulletin #352.
Gauge tube may be operated immediately, but best results will be obtained after the tube has outgassed for approximately 1
hour.
Tubes are temperature compensated, but do respond to rapid transient environmental changes (greater than 5 degree C/
min.) To minimize temperature transients effects please insulate gauge tube with glass wrap or other suitable insulation
wrap.
