Installing the Control Assembly Enclosure
WARNING
ELECTROCUTION HAZARD
Installing and servicing this equipment
requires access to parts which could
cause an electric shock or other serious
injury. Have only qualified electricians access the
control assembly enclosure.
Preparing to Install the Enclosure
Before installing the control assembly enclosure:
See component manuals for specific data on com-
ponent requirements. Data presented here pertains
to the PrecisionFlo control assembly only.
Have all system and subassembly documentation
available during installation.
Be sure all accessories are adequately sized and
pressure-rated to meet the system’s requirements.
Use only the Graco PrecisionFlo control assembly
with the PrecisionFlo metering valve.
WARNING
EQUIPMENT MISUSE HAZARD
The PrecisionFlo control assembly
weighs approximately 50 kg (110 lbs),
and should never be moved or lifted by
one person. Use adequate personnel and support
devices when mounting, moving or handling the
control assembly to prevent equipment damage or
personal injury.
Installing the Enclosure
1.
Select a location for the PrecisionFlo control
assembly enclosure. Keep the following in mind:
Allow sufficient space for installing and using the
equipment:
Make sure all fluid lines, cables and hoses
easily reach the components they will be con-
nected to.
Make sure there is sufficient clearance around
the assembly enclosure for running fluid lines
and cables to other components in the cell.
For 918463, make sure the hand-held pendant
reaches to a distance that provides easy ac-
cess for working with the robot and/or dis-
pense device.
Make sure there is easy and safe access to an
appropriate electrical power source. The Na-
tional Electrical Code requires 3 feet (91.4 cm)
of open space in front of the assembly enclo-
sure.
Make sure the control assembly is installed
between 1 foot (30.5 cm) and 4 feet
(121.9 cm) off the floor to provide easy access
for operating panel controls and also for serv-
icing the inside of the enclosure.
2.
Locate and secure the PrecisionFlo control assem-
bly enclosure with four 3/8¨ bolts through the .44”
diameter holes in the mounting flanges.
For 918463, see the mounting hole spacing
shown in Fig. 6.
For 918644, see the mounting hole spacing
shown in Fig. 7.
