Installation
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
Parts Drawing.
If you supply your own accessories, be sure they are
adequately sized and pressure-rated to meet the
system’s requirements.
Contact your Graco distributor for assistance in de-
signing a system to suit your particular needs.
Pump Location and Set-Up
1.
Place the unit on a hard, level surface. Check that
the unit is level in all directions. Refer to Dimen-
sions on page 28 to ensure that there is sufficient
overhead clearance for the pump when the ram is
fully raised. Leave room on both sides so the air
regulators will be easily accessible.
2.
Read the section System Components and
Accessories on page 9. Connect an air supply
hose to the 1/4 npt(f) main air inlet fitting (57). See
Fig. 2.
3.
Unpack the wiper plate (P). Back out the screws
(302) so they will clear the pump intake housing
(11). Raise the ram by setting the ram director
valve switch (36) to the UP position and increasing
the setting of the ram air regulator (27b).
4.
Place the wiper plate (P) on a 2 in. thick x 4 in.
wide block of wood. Center the wiper plate and the
wood block on the base, under the pump intake
housing (11).
5.
Set the ram air regulator (27b) to zero. Set the ram
director valve switch (36) to the DOWN position.
As the ram unit slowly falls, guide the pump intake
housing (11) into the wiper plate (P).
6.
Set the ram air regulator (27b) to 0.07 MPa, 0.7
bar (10 psi). Push down on the pump to install the
wiper plate (P) onto the intake housing (11). Se-
cure the wiper plate to the pump with the two
screws (302).
7.
Connect the 660 mm (26 in.) air line tube (76) from
the connector (37) at the air assist valve (18) to
the connector (310) at the wiper plate (P). Refer to
Connecting and Disconnecting Tubes.
Connecting and Disconnecting Tubes
Connection
1.
Grasp the tube, then slowly push it straight into the
fitting until it stops.
2.
Be sure that the tube is securely connected, and
will not pull out when air pressure is applied. To
check, pull back gently on the tube to ensure that it
will not pull out.
Disconnection
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
1.
Relieve the pressure.
2.
Push evenly on the fitting’s red release button.
3.
While holding the release button in, pull the tube
out of the fitting.
4.
To reuse the tubing, cut off the previously connec-
tion portion at 90
_
, being careful not to damage
the outer diameter of the tube. Use of a tube cutter
is recommended. The fitting will leak if the tubing is
not cut at 90
