Install an In-Drum Heavy Duty
Back Geared Agitator
1. Determine which size adaptor nut (20) is needed.
The adaptor nuts in the kit are double–sided
meaning that each adaptor nut will cover two
agitator shaft sizes. Select the size you need by
placing the adaptors onto the built in agitator shaft in
the drum. The one you should use is the smallest
one that will fit. There should only be a small
amount of slop between the adaptor nut and the
shaft.
2. Thread the adaptor into the gearbox output shaft (6)
with the side you are going to use pointed down.
Tighten it down using the wrench flats.
3. Place the threaded bung adaptor (34) onto the
gearbox and align the bolt holes.
4. Thread the three bolts (28) into the gear box and
torque to 10 ft-lbs (13.5 N•m).
5. Align the adaptor nut to engage the built–in shaft in
the 55–gallon drum.
6. Slowly screw the unit onto the threads on the center
bung fitting of the 55–gallon drum. Hand tighten to
secure the unit. The unit should not easily unthread
from the drum.
NOTE: To upgrade back-geared agitators with radial
piston air motors for high viscosity (500cP to 3000 cP)
material applications, see Retrofit Kit 25T862 or manual
3A4792.

3. Work the PTFE o-ring (54) onto the siphon tube
retainer (51), and press it into the o-ring groove.
4. Replace the top plug (5) with the siphon tube
retainer (51). Leave the retaining nut (52) on the
siphon tube retainer, but make sure it is not
tightened. Tighten the siphon tube retainer into the
top of the agitator housing with a wrench.
5. Slide the siphon tube (50) down through the retaining
nut (52), siphon tube retainer (51), and agitator shaft
(6) until the siphon tube touches the bottom of the
drum. Raise the siphon tube approximately 1/4 in.
(approximately 6 mm) so that it does not touch the
bottom of the drum. Hold the siphon tube at this
height with one hand, and tighten the retaining nut
with the other hand (hand tight is enough to hold the
siphon tube in place).
NOTICE
Barrel Heights Vary.
Loosen the retaining nut on the siphon tube retainer
before you raise the drum cover. If you do not loosen
the retaining nut, the siphon tube may make contact
with the bottom of the barrel when you lower the drum
cover onto a new barrel, which could damage the
siphon tube or the barrel.

Return Tube Kit 238884
(Accessory)
Return Tube Kit 238884 is available as an accessory. The
kit must be ordered separately. Refer to the sheet (406358)
packed with the kit for installation instructions.
Air Requirements
For continuous use, the 3/4 HP (550 W) agitator air
motor typically requires 3 to 4 cfm (0.09 to 0.12 m3/min)
air supply.
Air Line Accessories
A bleed-type air shutoff valve (SV) is required; it isolates
the air line components for servicing. The air shutoff
valve should be installed in the supply line and can be
used to stop and start the agitator. If the valve is used to
stop and start the agitator, you do not need to set the
agitator speed each time it is used.
Order air shutoff valves by the part numbers listed
below:
110223 1/4” npt(f) x 1/4” npt(f)
110224 3/8” npt(f) x 3/8” npt(f)
113333 3/8” npt(m) x 3/8” npt(f)
Optionally, attach a quick disconnect air line fitting and
coupler. To order the 1/8” npt(m) air line fitting, order part
number 169969. To order the coupler, order part number
208536.
Install an air line filter (AF) to remove harmful dirt and
moisture from the air supply. To order an air line filter,
order part number 106148 (3.8” npt, 20–micron element,
5 oz. Bowl, without gauge).
Downstream from the filter, install an air line lubricator
(AL) for automatic air motor lubrication. Set the
lubricator feed rate at 1 drop of oil per minute for high
speed or continuous duty usage. Do not overfeed oil or
exhaust air may become contaminated. To manually
lubricate the air motor, see Lubricate the Air Motor on
page 11. To order a 3/8” npt air line lubricator, order part
number 214847.

Operation
Find the Proper Agitator Speed
NOTE: Attach ground wire before using agitator.
1. Fill the fluid supply container to about 3–4 inches (75–
100 mm) above the agitator blade.
2. Start the agitator, and gradually increase the speed by
turning the needle valve (14) until a vortex begins to
form in the paint.
3. Reduce the speed slightly, then fill the fluid
container. Use the lowest agitator speed needed for
thorough agitation of the paint. Excessive agitator
speed may cause the paint to foam.
Pressure Relief Procedure
1. Close the bleed-type air shutoff valve (SV) to relieve
pressure to the air motor.
2. Disconnect the air line.
Shutdown
To stop the agitator, close off the air supply with the
needle valve (23) and close the bleed-type shut off
valve (SV), or disconnect the air line coupler.
Moving parts, such as an impeller blade, can cut or
amputate fingers. To reduce the risk of serious injury,
always shut off the agitator and disconnect the air line
before checking or repairing the agitator.
NOTICE
Always maintain moderate agitator speed, which is
approximately 50 rpm of the agitator blades.
Excessive agitator speed may cause vibration,
foaming of fluid, and increased wear on parts. Always
agitate fluid thoroughly before supplying it to the
dispensing equipment. Continue agitating fluid while
the dispensing equipment is being supplied.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
splashing fluid and moving parts, follow the Pressure
Relief Procedure before cleaning, checking, or
servicing the equipment.
NOTICE
Keep the agitator upright. Do not lay it on its side or
upside down, or liquid may flow down the shaft and
into the gear reducer area causing damage.
