The typical installation discussed below is only a guide
for selecting and installing system components and
accessories. Contact your Graco distributor for help in
designing a system to suit your particular needs.
This air-powered ram extruder forces high viscosity
fluids into the intake valve of the fluid pump. Wiper
rings and other accessory equipment for use with this
ram are listed in the Accessories section on page 54.
Selecting a Location for the Ram
Refer to the Ram Mounting and Clearance Dimensions
drawing (Fig. 14 on page 55) for ram mounting and
clearance dimensions.
When selecting a location for the ram, keep the follow-
ing in mind:
1. There should be sufficient space for installing and
using the equipment.
D
Make sure there is sufficient overhead clear-
ance for the pump and ram when the ram is in
the fully raised position.
D
Make sure the air regulators for the pump and
ram are fully accessible.
2. Make sure that you will be able to level the base of
the ram using metal shims.
3. When you bolt the ram to the floor, the anchors
should be long enough to prevent the unit from
tipping. Refer to the Dimensional Drawing on page
55 for more information.
System Accessories and Modules
Before you install the system you should be familiar
with the parts discussed below. For more information,
refer to Fig. 1, Typical Installation, on page 7.
Air and Fluid Hoses
When installing a system, make sure:
D all air and fluid hoses are properly sized for your
system.
D to use only electrically conductive air and fluid
hoses.

Typical Installation
D to use only Graco approved hoses. Do not remove
the spring guard that is used to help protect the
hose from rupture caused by kinks or bends near
the couplings.
To allow the gun to move more freely, use a short whip
hose between the main fluid hose and the gun.
Air Line Modules
WARNING
PRESSURIZED FLUID HAZARD AND
MOVING PARTS HAZARD
The pump bleed-type master air valve,
(C) in Fig. 1, is required in your system
to relieve air trapped between this valve
and the pump after the pump air regula-
tor is closed. Trapped air can cause the
pump to cycle unexpectedly, which could
result in serious injury, including splashing in the
eyes or on the skin and injury from moving parts.
3-Regulator Air Control Modules (shown in Fig. 1)
The following components are supplied with your
pump:
D Pump Bleed-type Master Air Valve (C) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING above). Be sure the bleed valve is
easily accessible from the pump, and is located
downstream from the air regulator.
D Pump Air Regulator (D) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
D Ram Down Air Regulator (not shown) controls the
air pressure to the ram.
D Ram Up Air Regulator (not shown) controls the air
pressure to the ram.
D Ram Air Supply Hose (H) connects the ram air
regulator to the air manifold.
D Air Manifold (F) divides the main air supply into
separate lines for the pump and ram.
