General Information
The Typical Installation shown is only a guide for
selecting and installing system components.
Reference letters in the text, for example (A), refer to
the callouts in the figures.
The SDU consists of parts which are stationary and
parts attached to the air cylinder center shafts. The
parts, such as the pump and platen, attached to
the air cylinder center shafts will raise and lower
(move) during normal operation. These moving parts
comprise the ram.
Performing different steps in the operation of the
SDU will require use of the controls located on the
control panel. Refer to the table under the illustration
that corresponds with the control panel installed
on the SDU for the use of those controls. Learn
what each control does before using the SDU in a
production situation.
Choosing a Location for the SDU
1. Choose a location for the SDU so the air controls
are easily accessible. Ensure that there is
enough space overhead for the ram to rise fully
and the control box cover can be opened without
interference. See Dimensions, page 50.
2. Make sure the surface is flat and that the SDU
doesn’t wobble.
NOTE: If the SDU is being located in a permanent
location, use the four holes in the baseplate as a
guide to locate where to drill holes for mounting
hardware.
3. For ease of operation and service, locate the
SDU so the fluid outlet port is easily accessible.
Unpacking the SDU
Before unpacking, examine packing materials for
signs of damage. If damaged, take pictures of the
damage and contact Graco for directions on how to
proceed.
1. Remove packing materials and mounting bolts
from the base.
2. Attach a hoisting strap around the upper end of
each air cylinder, below the crossbar. Ensure
that air hoses or laser sensor are not damaged
by the straps.
3. Use a forklift or overhead hoist to lift the SDU off
the shipping pallet.
NOTE: If using casters on a pneumatic unit,
attach at this time.
4. Place the SDU at the desired location.
5. Permanently mount the electro-pneumatic unit.

Installation
Line Accessories
See Fig. 1.
•Outlet Line Pressure Relief Valve (R): provides a
pressure relief path for the outlet line. Only needed
if a valve is used downstream in the outlet line
•Air line (T): use 1/2 in. ID minimum air line. Larger
ID is better, especially with line runs.
•Air line drain valve (U)
•Air line filter (V): removes harmful dirt and moisture
from compressed air supply.
•Second bleed-type air valve (W): isolates air line
accessories and supply system for servicing.
Locate upstream from all other air line accessories.
Grounding
The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
Before operating the pump, ground the system as
explained below.
•Electro-pneumatic control panel: If installed, it is
grounded through the grounding conductor of the
incoming power wiring.
•Air and fluid hoses: Use only grounded hoses with
a maximum of 500 ft (150 m) combined hose length
to ensure grounding continuity. Check electrical
resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
•Dispense valve: ground through connection to a
properly grounded fluid hose and pump.
•Fluid supply container: Follow local code.
•Solvent containers used when flushing: Follow
local code. Use only conductive metal containers,
placed on a grounded surface. Do not place the
container on a non-conductive surface, such as
paper or cardboard, which interrupts grounding
continuity.
•SDU: Attach the ground cables as shown. Attach
the clamp end of the grounding wire to a true earth
ground.
Check your system electrical continuity after the
initial installation, and then set up a regular schedule
for checking continuity to be sure proper grounding
is maintained. The resistance should not exceed 1
ohm when measured between line ground and any
metal on the system.

B – Ram lock bracket
C – Ram lock collar
3. To disengage the manual lock arm, lift the collar
above the bracket and move the lock arm away
from the bracket and back onto the storage
bracket on the platen support rod so that the
manual lock arm is restrained from undesired
movement.
NOTE:It may be necessary to raise the ram if
the pin of the lock arm is firmly engaged in the
bracket notch.
Install a Platen Inflatable Seal
This procedure assumes that no inflatable seal is
currently installed on the platen and the platen is
attached to the drum unloader assembly. If the platen
is detached from the pump lower, the inflatable seal
can be installed entirely from the top of the platen.
If there is currently a seal installed, to remove the
inflatable seal, read the procedure below to become
familiar with the steps, and then perform in reverse
order.
1. Raise the ram assembly to full height and engage
the ram lock to prevent inadvertent ram lowering.
2. At the rear of the platen, insert the inflation tube
through the access hole in the recessed groove
and ensure that the hose protrudes out of the
hole on the top of the platen.
NOTICE
To prevent damage to the seal or seal air
hose, ensure that the inflation hose is properly
centered in the platen hole.
3. Carefully center the inflation hose in the hole
and press the seal into the platen groove. A
flat is provided on the platen retaining flange to
aid installation. Hold the seal in place and work
around one side of the platen, working the seal
into the platen groove. Repeat on the other side
of the platen.
NOTE: Afood safe lubricant can be used to
assist in sliding the seal over the platen lip, but is
not required.
4. At the front of the platen, work the remainder
of the seal over the platen lip, working to install
the seal into the remaining portion of the platen
groove.
5. Verify that the seal inflation tube is properly
positioned in the hole at the back of the platen.

Keep hands and fingers away from the platen,
pump fluid inlet, and lip of the fluid container when
raising or lowering the ram to reduce risk of serious
injury from moving parts.
NOTICE
To prevent pinching or damaging the seal during
drum insertion, only inflate the seal when the top
lip of the platen is at, or below, the top edge of the
drum.
To prevent the seal from restricting smooth
movement of the platen within the drum, only
inflate the seal until it makes contact around the
perimeter of the drum.
1. For Exposed Control Panel:
a. Connect pump outlet fittings and hose (not
supplied).
NOTE: Be sure all components are
adequately sized and pressure rated to meet
the system’s requirements.
b. Using the ram director valve, lower the platen
into the drum until it contacts the product in
the drum.
c. If system is equipped with an inflatable seal
and the platen is located far enough into
the drum to properly inflate the seal, inflate
it now. If the platen is not far enough into
the drum for seal inflation, wait until enough
product has been evacuated to lower the
level of the platen in the drum before inflating.
d. Move the air motor slider valve to the 1
(open) position. Observe that the pump
begins to operate. Adjust air motor air
pressure as needed.
e. Move the ram director valve to the down
position. Observe that the ram lowers
as product is evacuated. Adjust ram air
pressure as needed.
f. If using an inflatable seal and it has not yet
beeninflatedandtheplatenhasloweredfar
enough into the drum, inflate it now.
g. Using the pressure settings for the various
functions, fine tune the pressures as needed.
NOTE: Increase air pressure to the ram if the
pump does not prime properly with heavier
fluids. Decrease air pressure if material is
forced out around the platen seal.
2. For Enclosed Pneumatic Control Panel:
a. Connect pump outlet fittings and hose (not
supplied).
NOTE: Be sure all components are
adequately sized and pressure rated to meet
the system’s requirements.
b. Using the ram position control switch, lower
the platen into the drum until it contacts the
product in the drum.
c. If system is equipped with an inflatable seal
and the platen is located far enough into
the drum to properly inflate the seal, inflate
it now. If the platen is not far enough into
the drum for seal inflation, wait until enough
product has been evacuated to lower the
level of the platen in the drum before inflating.
d. Move the air motor control switch to the run
position. Observe that the pump begins to
operate. Adjust air motor air pressure as
needed.
e. Move the ram position control switch to the
down position. Observe that the ram lowers
as product is evacuated. Adjust ram air
pressure as needed.
f. If using an inflatable seal and it has not yet
beeninflatedandtheplatenhasloweredfar
enough into the drum, inflate it now.
g. Using the pressure settings for the various
functions, fine tune the pressures as needed.
NOTE: Increase air pressure to the ram if the
pump does not prime properly with heavier
fluids. Decrease air pressure if material is
forced out around the platen seal.

3. For Electro-pneumatic Control Panel:
a. Connect pump outlet fittings and hose (not
supplied).
NOTE: Be sure all components are
adequately sized and pressure rated to meet
the system’s requirements.
b. Be sure the pump is set to pause. Set the
ram down air pressure to 10 psi (0.06 MPa,
0.6 bar).
c. Touch ram jog icon and lower the ram until it
just contacts the product.
d. If the ram plate is inside the drum, inflate the
seal.
NOTE: To prevent damage to the seal, use
the lowest seal pressure that still allows the
seal to contact the inside surfaces of the
drum.
e. Start the pump at the slow (turtle) speed
setting until the pump is primed. If necessary,
adjust the pump pressure.
f. Touch ram down icon.
g. Using the pressure settings for the various
functions, fine tune the pressures as needed.
NOTE: Increase air pressure to the ram if the
pump does not prime properly with heavier
fluids. Decrease air pressure if material is
forced out around the platen seal.
