The following should be taken into consideration when installing the converter:
(1) Readability of the indicated values of oxygen concentration or messages on the
converter display.
Easy and safe access to the converter for operating keys on the panel.
(2) Easy and safe access to the converter for checking and maintenance work.
(3) An ambient temperature of not more than 55 C and little change in temperature
(recommended within 15 C in a day).
(4) The normal ambient humidity (recommended between 40 to 75% RH) and without
any corrosive gases.
(5) No vibration.
(6) Near to the detector.
(7) Not in direct rays of the sun. If the sun shines on the converter, prepare the hood (/
H) or other appropriate sunshade.
The converter can be mounted on a pipe (nominal JIS 50A: O.D. 60.5 mm), a wall or a
panel. The converter can be mounted at an angle to the vertical, however, it is recom-
mended to mount it on a vertical plane.
Mount the converter as follows.
<Pipe Mounting>
(1) Prepare a vertical pipe of sufficient strength (nominal JIS 50A: O.D. 60.5 mm) for
mounting the converter. (Converter weighs approximately 6 kg.)
(2) Mount the converter on the pipe. Fix it firmly on the pipe in the procedure described
in Figure 3.7.
