3.6 Installation of the Calibration Gas Unit Case (E7044KF)
The calibration gas unit case is used to store the G7001ZC zero gas cylinders.
3.6.1 Location
The following should be taken into consideration:
1. Easy access for cylinder replacement
2. Easy access for normal operation
3. Close proximity to the detector and converter as well as the flow setting unit.
4. The temperature of the case should not exceed 40°C from exposure to direct sunlight or radiated
heat.
5. Isolated from vibration
3.6.2 Mounting
Mount the calibration gas unit case on a pipe (nominal JIS 50A) as follows:
1. Use 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 U-bolt such that the metal fitting is firmly
attached to the pipe.
