The C7024E has notch and arrow indicators (see Fig. 7)
on the faceplate to facilitate mounting in positions other
than those shown in Fig. 6. The notch and arrow must be
vertically aligned with the notch in the up position and the
arrow pointing downward. The C7024F must be mounted
with the conduit opening located approximately 45 de-
grees below the horizontal (see Fig. 7).
IMPORTANT: The notch and arrow on the C7024E
faceplate must be aligned in a vertical plane with
the notch up and the arrow pointing downward.
The C7024F housing must be mounted with the conduit
opening approximately 45° below horizontal (see Fig. 7).

To mount a C7024E (see Fig. 8):
1. The mounting flange is in two pieces. Loosen, but
do not remove, the three screws holding the flange
together.
2. Slightly rotate the detector so the slots in the back
section of the mounting flange clear the screws in the
front section, then separate the two sections.
3. Screw the front section of the mounting flange
onto the sight pipe, reducer, or other fitting.
4. Fit the slots in the back section of the mounting
flange (with the detector) over the three screws in the
front section, and rotate the detector so that the screws
hold the flange together.
5. Securely tighten the screws.
To mount a C7024F with explosion-proof housing
(see Fig. 9):
1. Unscrew the collar on the pipe union and remove
the coupling section. The collar and coupling are in two
pieces; do not separate them.
2. Screw the coupling onto the sight pipe, reducer, or
other fitting.
3. Mount the rest of the pipe union (with the detec-
tor) on the coupling and securely tighten the collar.
