3.3 Installation of ZA8F Flow Setting Unit
3.3.1 Location
The following should be taken into consideration:
(1) Easy access to the unit for checking and maintenance work.
(2) Near to the detector and the converter for operating keys on the panel.
(3) No corrosive gas.
(4) An ambient temperature of not more than 55
ЊC and little changes of temperature.
(5) No vibration.
(6) Little exposure to rays of the sun or rain.
3.3.2 Mounting of ZA8F Flow Setting Unit
The flow setting unit can be mounted either on a pipe (nominal JIS 50A) or on a wall. It
should be positioned vertically so that the flowmeter works correctly.
<Pipe Mounting>
(1) Prepare a vertical pipe of sufficient strength (nominal JIS 50A: O.D. 60.5 mm) for
mounting the flow setting unit. (The unit weighs approximately 2 to 3.5 kg.)
(2) Mount the flow setting unit on the pipe by tightening the nuts with the U-bolt so that
the metal fitting is firmly attached to the pipe.
