REGULATOR AND HOSE INSTALLATION
1. Secure gas cylinder to a wall, bench or stand with a mounting bracket so it will not
tip over or fall.
2. Be sure both the regulator and cylinder have compatible CGA fittings. Do not
attempt to use an adapter to connect incompatible CGA fittings.
3. Inspect cylinder's and regulator's Standard Compressed Gas Association (CGA)
connections for damage, dirt, dust, oil, or grease. Do not use if either is damaged.
Remove all traces of foreign materials with a clean, lint-free cloth.
4. Attach the regulator to the cylinder and tighten the CGA connection nut counter-
clockwise.
5. Verify that the regulator's valve is closed.
6. Observe the inlet supply pressure gauge, which will verify cylinder pressure.
7. Connect the 3/16" ID tubing with a threaded hose barb (Part No. TB-512) to the hose
barb on the regulator and secure with a cable clamp.
CALIBRATION
1. Use either the automatic or manual calibration procedure described in Part 2,
"Calibration and Alarm Level Selection".
2. When finished close the regulator valve.
CAUTION:
Always attach the detector's water-block filter to the threaded hose barb (TB-
512) with the regulator off, wait for
"bloc",
then open regulator's valve.
Blocking the flow with the regulator's valve open can result in a pressure
surge when the flow is resumed which will damage the detector's pump.
