NOTES:
1.
AV1 _ _ _ _ _ _is cFMus approved only for general purpose and non-incendive installations.
2.
AV23 _ _ _ _ _ is cFMus approved only for general purpose and non-incendive applications.
AV27 _ _ _ _ _ is FM/CSA approved for use in explosion-proof or intrinsically safe applications.
3.
High temperature Type AV1 positioners are only available without manifolds or position transmitters; however, gauge
blocks are permitted.
4.
Explosionproof Type AV27 positioners are not available with position transmitters or manifolds.
5.
The Type AV_ _ _ _ _ _N positioner comes with a NEMA 4X housing. To maintain the NEMA 4X classification, the
positioner shall be installed per drawing C258567 and suitable piping shall be attached to the vent opening and vented
in a manner to preclude the entrance of water under pressure, as from a hose. Additionally, the conduit connections shall
be suitable for a NEMA 4X rating.
