Overview
Operation Overview
The SaniForce BES evacuates fluids from a 300 gallon
(1135 liter) bag in a plywood box, IBC, or collapsible bin.
The SaniForce BES consists of a frame, two or four
Graco pumps, ram plate with an inflatable seal, ram air
cylinder, and a manual or electronic control panel.
Basic Operation of SaniForce
BES
1. The operator places the bin inside the frame.
2. Using the control panel, the operator lowers the ram
plate on top of the material.
3. The operator aligns and centers the bin with the ram
plate.
4. The operator inflates the ram plate seal, applies
down pressure to the ram plate, and turns on the
pumps.
5. The pumps evacuate the material out of the bin.
6. The operator stops the pumps, deflates the seal,
and raises the ram plate out of the bin.
7. The empty bin is removed, another bin is put in
place, and the SaniForce BES is ready to repeat the
process.

Overview
8311163ZAH
System Components (Manual Control)

Before Installing
Uncrating Equipment
Uncrate the SaniForce BES as follows:
1. Inspect the crate for shipping damage. Contact the
carrier if damaged.
2. Remove plywood sides and top of crate.
3. Check the contents for loose or damaged parts.
4. Compare the packing slip against items inside the
crate. Immediately call your Graco distributor about
any shortages or damage.
5. Remove the band strap holding the cylinder bin to
the frame.
6. Remove and unpack the air cylinder bin and pumps
(if applicable).
NOTE: See your system component manuals to
become familiar with system components and general
operation.
Location
When selecting a location, make sure the location:
• Is close to where the fluid is being delivered to mini-
mize back pressure and maximize flow rate.
• Provides enough room around the equipment for
maintenance.
• Does not interfere with opening the pneumatic con-
trol panel door or frame door (on one or both sides).
If the frame is rotated 180°, the frame door will open
from left to right or from right to left.
• Provides enough room on the right and/or left side
of the SaniForce BES to easily load and unload fluid
bins with a forklift or pallet-jack hand truck.
• Provides easy and safe access to the air supply
shutoff valves and the pneumatic control panel.
Graco recommends a minimum of 3 ft (0.91 m) of
open space in front of the panel.
• Provides enough overhead clearance (11 ft, 3.4 m
recommended) for installing and servicing the air
cylinder and connecting air supply lines to the pneu-
matic control panel.
• Has a flat, level floor.
Moving Frame to Location
• Do not remove the frame from the pallet at this time.
• Use a forklift or hand truck and support devices,
such as a hoist, and have an adequate number of
personnel to move the frame to the installation site.
• Avoid jarring or tilting the frame while moving it.
NOTE:
• Ensure there is an adequate compressed air supply.
Refer to air motor/pump manual for your pump air
consumption. About 250-300 scfm at 100 psi (0.7
MPa, 7 bar) is required to operate the pumps at the
maximum rate.
• Have all component manuals available for specific
component requirements.
• Ensure that all hoses are properly sized and pres-
sure rated for the system.
NOTICE
Moving the SaniForce BES off the pallet without follow-
ing this uncrating procedure will damage equipment.
The frame is shipped with several major components
attached and weighs about 2500 lb. (1134 kg). To
avoid injury and equipment damage, follow
instructions below. Never have one person move or
lift the frame.

Installation
311163ZAH 11
Installation
Anchoring Frame
1. Remove bolts holding the frame (602) to the ship-
ping pallet.
2. To lift the system, use the top joists on the frame
with a forklift. Have an adequate number of person-
nel to lift or move the unit; avoid jarring or tilting it.
3. Remove the pallet and all remaining shipping sup-
ports from underneath the frame.
The four base footings of the frame and the bottom of
the bin must be level on the same surface in order for
the SaniForce BES to operate properly. If necessary,
level the SaniForce BES using sanitary metal shims.
Make sure the frame does not wobble.
Anchor the four foot pads to the floor. To prevent the
frame from being pushed off the floor, the anchor bolts
must be long enough to withstand the 5027 lb. (22.36
kN) of downward force that the air cylinder can exert.
Use the holes in the four base footings as a guide and
drill holes for 1/2 in. (13 mm) bolts. Bolt the frame to the
floor with anchors.
Installing Air Cylinder
NOTE: All models do not use the same parts. Refer to
parts lists for your model, pages 35-45.
1. Using a hoist, lift the air cylinder (4) into position on
top of the frame (602). See FIG. 3.
2. Lower the air cylinder shaft (A) through the center
hole in the frame.
3. Secure the air cylinder (4) to the frame (602) with
the screws (20) and washers (19). See FIG. 4.
4. Install the air motor mounting plate (402), slipping
plate over the top and down the length of air cylinder
(4).

• The output hose(s) (supplied by others) should
already be installed, with riggings and supports, and
ready for connection to the 2 in. tri-clamp (412, sup-
plied on some systems). See FIG. 5.
• Make sure the output hose(s) are sized and pres-
sure-rated for the system. Use only electrically con-
ductive hoses with spring guards on both ends.
• The fluid hoses must move freely, without kinking,
when the pumps move up and down.

Grounding
Pump: use the ground wire and clamp (supplied). There
are two styles of grounding connections on pump air
motors.
If you have ground screw shown in FIG. 6, you need
to order part no. 222011 ground wire, ring terminal, and
clamp assembly (Y). To install 222011, remove the
ground screw (Z) and insert it through the eye of ring ter-
minal (X), then tighten ground screw back into air motor
as shown in FIG. 6. Connect the other end of the wire to
a true earth ground.
If you have ground screw shown in FIG. 7, loosen the
grounding lug locknut (W) and washer (X). Insert one
end of the ground wire (Y) into the slot in lug (Z) and
tighten the locknut securely. Connect the other end of
the wire to a true earth ground. Order 237569 ground
wire and clamp assembly.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity. Check the electri-
cal resistance of your air and fluid hoses. If the total
resistance to ground exceeds 29 megohms, replace the
hose immediately.
Air compressor: follow manufacturer’s recommenda-
tions.
Dispense valve: ground through connection to a prop-
erly grounded fluid hose and pump.
Fluid supply container: follow your local code.
Solvent pails used when flushing: follow your local
code. Use only conductive, metal pails, placed on a
grounded surface. Do not place the pail on a noncon-
ductive surface, such as paper or cardboard, which
interrupts grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold a metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the gun/valve.
Checking Resistance
Have a qualified electrician check the resistance
between each pump and true earth ground. Resistance
must be less than 0.25 ohms. If the resistance is
greater, a different ground site may be required. Do not
operate the system until you correct the problem.
Prepare the Operator
Anyone operating the equipment must be trained to
safely operate all system components and properly han-
dle fluids used. Operators must read all instruction man-
uals, tags, and labels before operating equipment.
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.

Pressure Relief Procedure
1. To turn off the pumps move pump switch to OFF.
2. Shut off the air to the pumps by closing the
bleed-type air shutoff valve on the pumps’ air supply
line, or disconnect the air line.
3. Open all system fluid drain valves that are down-
stream of the pumps.
Initial Startup
This procedure takes you through the settings, adjust-
ments, and other steps that must be completed before
the system is ready for daily operation.
1. Fill all the pumps packing nut/wet cups 1/3 full with a
compatible lubricant if applicable. Refer to your
pump manual for details. Do not use Graco Throat
Seal Lubricant with a sanitary application.
2. Turn on the air to the pneumatic control panel.
3. Turn SEAL INFLATE to OFF.
4. Open the air shutoff valves for the pneumatic con-
trols and pumps.
5. Open the pneumatic control panel door. Check for
air leaks.
6. The equipment was tested with water. Flush the
system before loading material. See page 28.
7. Follow Loading the Bin procedure, page 18.
8. Set the ram down air regulator to 30 psi (207 kPa,
2.1 bar). Adjust as needed.
9. Adjust the pump regulator as needed.
NOTE: Pump cavitation occurs when the pump cylinder
does not fully load with material on the up stroke and an
air pocket forms in the material after the pump change-
over. If pump cavitation occurs, increase the ram down
air pressure.
10. Adjust the seal vacuum pump air regulator to 15 psi
(103 kPa, 1.0 bar).
11. Deflate the seal.
12. Press the RAM UP button. If the ram does not raise,
increase the ram up air regulator pressure.
13. Verify the seal is completely deflated after the ram
plate exits the bin. If it is not, deflate the seal.
14. When adjustments are complete, close the pneu-
matic control panel door.
15. Follow Unloading the Bin procedure, page 18.
16. The system is now ready for standard operation.
See page 17.
Setting Air Pressures
Each system function has an associated air pressure.
Air pressure regulators are located on the pneumatic
control panel. Set initial air pressures as shown in the
table below. Make adjustments as needed during opera-
tion. See FIG. 9.
*A pressure relief regulator is required when a control
system other than a Graco control panel is used.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from injection, splashing or moving parts. Relieve
pressure when you stop pumping and before
cleaning, checking, or servicing equipment.
When raising or lowering the ram plate, keep hands
and body away from ram plate and bin lip.
