The typical installation discussed below is only a guide
for selecting and installing system components and
accessories. Contact your Graco representative or
Graco Technical Assistance for help in designing a
system to suit your particular needs.
This hydraulic-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 71.
Selecting a Location for the Ram and
Hydraulic Power Supply
For information about the dimensions of the ram and
hydraulic power supply, refer to the mounting and
clearance dimension drawings, Figs. 36 and 37 on
pages 72 and 73.
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.
Make sure there is sufficient overhead clear-
ance for the pump and ram when the ram is in
the fully raised position.
If you are installing a vent hood, make sure
there is sufficient horizontal clearance for it.
Make sure the air regulators for the pump and
ram are fully accessible.
Make sure there is easy and safe access to an
appropriate electrical power source. The
National Electrical Code requires 3 feet of
open space in front of the electrical panel.
Locate the hydraulic power supply in an area
that:
– has easy access for servicing and adjust-
ing the hydraulic pressure on the supply
unit
– has sufficient clearance for the hydraulic
lines that you will attach to the pump
– will allow you to easily read the hydraulic
fluid level gauge

Typical Installation
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 72 for more information.
4. If you are installing a vent hood, make sure the
ram is installed near a connection to the factory
ventilation system.
5. Place the hydraulic power supply so there is easy
access for servicing the unit.
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, A Typical Installation, on page 7.
Air and Fluid Hoses
WARNING
FIRE HAZARD
Only use hoses that have a maximum
wattage less than or equal to 1250
watts. Using hoses with higher maximum wattage
could create a runaway temperature condition.
The Therm-O-Flow 55-H unit was designed for use
with single-circuit material hoses that are rated at a
maximum of 1250 watts. For information about using
material hoses with higher wattages, contact your
Graco technical support representative.
When installing a system, make sure:
all air and fluid hoses are properly sized for your
system.
to use only electrically conductive air and fluid
hoses.
