Agitator
To reduce the risk of fire and explosion, always
maintain a minimum of 1 in. (25.4 mm) clearance
between the rotating agitator parts and the
container to prevent sparks from contact.
• If installing a new agitator onto a new tank, follow
steps 1– 2, and 7–15 (models 25C536, 25C537,
25C538).
• If replacing an established agitator, follow steps
1, 3–12, and 14–15 (models 25C539, 25C540,
25C541).
1. Relieve pressure from the system (if
applicable) by following the procedure in the
Pressure Relief Procedure, page
the pressure tank cover from the tank.
2. Unscrew and remove the hex jam nut (49), plug
(P), and o-ring (R) from the tank cover.
3. Remove the upper U-bolt (56).
4. Loosen the two agitator paddle set screws (46)
and remove the agitator paddle (45).
5. On 10 and 15 gallon tanks, remove the lower
U-bolt (56), loosen screws (54), and slide the
baffle (53) off the fluid tube (12).
6. Unscrew and remove the hex jam nut (49),
gasket (50), and agitator from the tank cover.
7. To install the new agitator, place the gasket (50)
on top of the tank cover center hole. Insert the
agitator shaft (47) through the gasket and center
hole.
NOTE: Position the air motor and regulator as
shown in
Typical System, page 5
8. Install the jam nut (49) below the tank cover,
and tighten firmly to assure a seal between the
gasket (50) and tank cover.
9. Install the shaft support (44) onto the shaft
housing (42).
10. Clamp with upper U-bolt (56), clamp (43), lock
washer (41), and nut (55).
Tighten the U-bolt at a position leaving
approximately 0.015 in. (0.006 mm) clearance
gap between the thrust washer and the top of
the shaft support.
11. On the 10 and 15 gallon tanks, place the lower
bearing assembly (66) and (67) on the shaft.

11, and remove
.
12. On the 5 gallon tank, clamp the lower U-bolt
directly to the shaft support (44) (see below).
Slide the baffle (53) over the fluid tube (12) and
position the baffle about 1/2 in. (13 mm) above
the highest point on the agitator paddle (45).
Clamp in place with the lower U-bolt (56), washer
(41), and nut (55).
Misalignment between the shaft and fluid tube
may cause the agitator shaft to bind when
clamping the U-bolt (56) in place. Loosen if
required to allow shaft rotation. The agitator
motor should run at 20 psig (1.4 bar) air pressure
when dry.
13. Align the agitator paddle (45) on the agitator
shaft (47) as follows:
• For 10 and 15 gallon tanks: Align the top of the
paddle hub with the lower mark on the agitator
shaft.
• For 5 gallon tanks: If a 5 gallon pail is to be
placed inside the pressure tank, align the top
of the paddle hub with the upper mark on the
agitator shaft. If a pail is not to be placed inside
the tank, align the top of the hub with the lower
mark on the agitator shaft. After the paddle is
properly aligned, apply low strength sealant to
the two set screws (46) and firmly secure the
paddle.
14. Remove the plug or existing elbow from the air
inlet manifold (5). Install the new elbow (69) into
the pressure tank air inlet manifold.
15. Connect the swivel end of the air hose (70) to
the elbow (69).
