Mounting the Unit
The 7xxC Series unit can be mounted with the cylindrical end in either a vertical or horizontal
position. The mounting requirements allow any foreign matter entering the pressure port to fall
away from the sensing diaphragm.
Mounting the Unit in a Vertical Position
Mount a unit with high full scale pressure (greater than or equal to 20 psi) in any position
vertically. If the unit has a low full scale pressure (less than 20 psi) and is used with gases that
contain particulates, mount it in a vertical position with the cylindrical end of the unit pointing
upward, as shown in Figure 3, page 26. Do not install such a unit with the cylindrical end of the
unit pointing downward because particulate impurities may accumulate on the sensing diaphragm
and alter the pressure reading.
