Connecting Fluid and Air
Lines
Follow the instructions in your separate component
manuals to connect air and fluid lines. General guide
lines are provided below.
•
The PrecisionFlo LT fluid module should be installed
on the automation unit or in another appropriate
place, as close as practical to the dispense valve.
•
Connect a fluid line between the fluid module outlet
and the dispense device. Smaller diameter and
shorter fluid lines (hoses) will provide better fluid sys-
tem response.
•
Connect a fluid line to the flow meter fluid inlet or reg-
ulator inlet if your system does not have a flow meter.
•
Air must be clean and dry, between 60-120 psi (0.41
MPa - 4.14 bar). Flush air line before plumbing in air
filter assembly (234967). Plumb in air filter assembly
near air drop site (upstream of fluid plate module).
Adding an air regulator to this line will provide more
consistent dispense valve response times.
•
Connect an air supply line to the 1/4 npt inlet port on
the fluid module(s) air supply inlet.
•
Connect 5/32 in. or 4 mm OD air lines from the appli-
cator's solenoid valve to the applicator. Plug any
unused solenoid ports.
To maximize system performance keep the dis-
pense hose length and ID as small as the application
will allow.
Grounding the Metering Assembly
Grounding the Fluid Metering Assembly
Ground the fluid metering assembly as instructed here
and in the individual component manuals. Make sure the
fluid metering assembly and its components are
installed correctly to ensure proper grounding.
Air and Fluid Hoses
For static dissipation, use only electrically conductive
hoses or ground the applicator / dispense valves.
Metering Module
The PrecisionFlo LT fluid metering assembly is
grounded to the control assembly through proper con-
nection of the electrical cable provided with the metering
module.
Dispense Device
Follow the grounding instructions in the dispense device
documentation.
CAUTION
Route all fluid and air lines carefully. Avoid pinching
and premature wear due to excessive flexing or rub-
bing. Hose life is directly related to how well they are
supported.
WARNING
Read Warnings, page 6.
CAUTION
If power and grounding connections are not done
properly, the equipment will be damaged and the war-
ranty voided.
