Note: Recommended panel hole diameter: 0.78 inch (19.8 mm).
Note: The AP3625 (except 1
1
/
8
inch surface mount models) and AP4625 series valves have
five available handle designs, one standard and four optional. The option designators are
included at the end of the model number, such as AP3625SM 2PW FV4 FV4 BB with the
“BB” specifying the option. The standard handle does not require a designator. The other
four are BB, TN, LT and FK. The 1
1
/
8
inch surface mount AP3625 valves have the FA
handle standard and are designated with an “FA” at the end of the model number (e.g.,
AP3625S 2P FA). The FA and FK handles are identical.
A. Required Tools and Equipment
• 1/8 inch hex bit and 50 in·lbf (5.6 Nm) torque wrench. Optionally a 1/8 inch hex key may be
used if an appropriate torque wrench cannot be obtained.
• 5/64 inch hex bit and 20 in·lbf (2.3 Nm) torque wrench. Optionally a 5/64 inch hex key may
be used if an appropriate torque wrench cannot be obtained.
• 1 inch wrench (open end or adjustable).
B. Handle Removal (Refer to Figure 1)
1. Remove the valve from the double plastic bag.
2. Close the valve by turning the handle fully clockwise.
Note: Remember the orientation of the handle in the “closed” position so that it may be re-
oriented in the same position during re-assembly.
3. Use a 1/8 inch hex key to loosen the pointer (#1) (used in standard or “BB” handles only) and
both set screws (#2) a couple of turns.
Note: Be careful not to rotate the stem (#3) counter-clockwise. If the stem accidentally
rotates, re-tighten both set screws and start from the step B.2. again.
4. Lift up the handle assembly to remove it from the valve.
5. Use a 5/64 inch hex key to loosen both set screws (#4).
6. Lift up the indicator plate (#5) to remove it from the valve.
C. Panel Mount (Refer to Figure 1)
1. Remove the panel mount nut (#6) from the unit.
2. Place the valve through the panel hole, position the valve as desired, connect the valve into
piping system and replace the panel mount nut onto the unit.
3. Using a 1 inch wrench, tighten the panel mount nut firmly against the panel.
D. Handle Replacement (Refer to Figure 1)
1. Place the indicator plate (#5) on top of the cap (#7).
2. Place the handle assembly on top of the stem (#3).
Note: Ensure the pin on the bottom of the handle assembly fits into the quarter-circular slot
on the top of the indicator plate.
3. Turn the handle clockwise until it drags the indicator plate. Then, continue rotating clockwise
until the handle is oriented in the proper closed position.
