Load Material - Graco E-Flo iQ Operation Manual

Load Material

The following steps are required when you are loading
material in the system for the first time. This procedure
should be performed after the E-Flo iQ system is
installed, flushed, and ready for operation. Refer to the
E-Flo iQ Supply System Installation-Parts manual for
installation. See Related Manuals on page 3.
For additional information about the E-Flo iQ Run
screens, including priming and depressurization, see
Operation on page 38.
NOTE: For an E-Flo iQ system with a Platen Valve (AY)
installed, you need to ensure that the Platen Valve
setting is enabled in the Pump Settings on the ADM
before starting this procedure. See Pump Screen 2 -
Drum Settings on page 27.
NOTE: For Tandem systems, complete all steps in the
following sections on both ram supply units before
performing the steps in Load the Hose and Dispense
Valve:

Prepare the Pump
1. For Tandem Systems, ensure the Ball Valves (S) on
the Tandem Block (R) are closed.
2. Turn on the Disconnect Switch (AZ). If using a
heated system, also turn on the Power Junction Box
switch (AK).
3. Open the Main Air Slider Valve (BA) on the
Integrated Air Control and set the Ram Air
Regulator (BB) to 40 psi (.20 MPa, 2.0 bar).
4. Move the Ram Director Valve (BC) up to raise the
Ram (AA) to its full height.
5. Set the Ram Director Valve (BC) to neutral
(horizontal position).
6. Lubricate the Platen Wiper with grease or another
lubricant compatible with the material being loaded.

7. Place a full pail or drum of material on the Ram (AA)
base and center it under the Platen (AD). Then
remove the drum cover and smooth the surface of
the material with a straightedge.
8. To prevent air from being trapped under the Platen
(AD), scoop fluid from the center of the pail/drum to
the sides to make the surface concave.
9. Adjust the pail/drum to make sure it is aligned with
the Platen (AD).
10. Remove the Platen Bleed Stick to open the Platen
Bleed Port (AH).
NOTE: If a Platen Valve (AY) is installed on the system,
do not connect the Recirculation Hose (ZB) to the Platen
Valve Port until you have completed loading material
through the system.
11. With your hands away from the pail/drum and the
Platen (AD), move the Ram Director Valve (BC)
down to lower the Ram (AA) until the Platen (AD)
rests on the lip of the pail/drum.
12. Return the Ram Director Valve (BC) to the neutral
position.
Load the Platen and Platen Valve
1. For Tandem systems, ensure the Ball Valves (S) on
the Tandem Block (R) are closed.
2. Move the Ram Director Valve (BC) down to lower
the ram until material appears at the Platen Bleed
Port (AH).
3. Return the Ram Director Valve (BC) to the neutral
position.
4. Replace the Platen Bleed Stick that was removed in
step 8 in Prepare the Pump.
