3.6 Installation of the Calibration Gas Unit Case
(E7044KF)
3.6.1
Location
3.6.2
Mounting
3-16
The calibration gas unit case is used to store the G7001ZC zero gas cylinders.
The following should be taken into consideration:
(1) Easy access for cylinder replacement
(2) Easy access for checking
(3) Near to the detector and converter as well as the flow setting unit.
(4) The temperature of the case should not exceed 40 C due to rays of the sun or
radiated heat.
(5) No vibration
Mount the calibration gas unit case on a pipe (nominal JIS 50A) as follows:
(1) Prepare a vertical pipe of sufficient strength (nominal JIS 50A: O.D. 60.5 mm) for
mounting the flow setting unit. (The sum of the calibration gas unit case and the
calibration gas cylinder weighs approximately 4.2 kg.)
(2) Mount the unit case on the pipe by tightening the nuts with the U-bolt so that the
metal fitting is firmly attached to the pipe.
