Typical Installation
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 70.
NOTE: For more information about converting the ram
from air to hydraulic operation, contact your Graco dis-
tributor.
Selecting a Location for the Ram
Refer to the Ram Mounting and Clearance Dimensions
drawing (Fig. 43 on page 73) 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.
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.
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
73 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.
System Accessories and Modules
Before you install the system you should be familiar
with the parts discussed in the subsequent para-
graphs.
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 maxi-
mum wattage could create a failure in
the electrical circuit.
The Therm–O–Flow 55 unit was designed for use with
single–circuit material hoses that are rated at a maxi-
mum of 1250 watts. For information about using
material hoses with higher wattages, contact your
Graco distributor.
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.
