Installation Instructions
(cont'd.)
Top Assembly Rotation
Maxon valves can and should be ordered in a con-
figuration compatible with planned piping, but if open/
shut indicator window is not visible and/or valve orienta-
tion is not proper, the top assembly can be rotated in
90° increments around the valve body centerline axis
by the following procedure:
1. Shut off all electrical power and close off up-
stream manual cock.
2. Remove wiring access cover plate [2] and
disconnect power lead wires. (Tag carefully for later
re-assembly.)
3. Remove conduit and electrical leads.
4. Note physical position of any signal switch
actuator wands on auxiliary signal switches (see
switch arrangement sketch).
5. Unscrew the two body bolts [4] screwed up from
the bottom to 1/4 inch. DO NOT completely re-
move. These bolts secure the valve body [3] to the
valve’s top assembly housing [5].
6. Gently lift the top assembly [5] (not more than
1/4" in height); just enough to break the seal
between the valve body assembly and the rubber
gasket adhering to the bottom of the top housing.
WARNING: LIFTING TOO FAR MAY DISLODGE
SOME SMALL PARTS INSIDE THE TOP
HOUSING, REQUIRING COMPLEX RE-
ASSEMBLY AND RETESTING BY TRAINED
FACTORY PERSONNEL.
