Updating Application Programming (.S19 file)
An .S19 file can be downloaded to the circuit board with the user interface
software as follows:

Shut engine down.

From any screen, type Alt-D (hold the Alt key and press D at the same time).

An input message at the bottom of the screen will request the password
included with the update software. Contact your GECO distributor for more
information.

Another message will request the pathname of the new .S19 file (example:
c:\geco\9925050.s19).

The new program will then be downloaded to the flash memory.
Fuel Metering/Valve Location Considerations

Access for conduit connection

Space for servicing and repair

Protection from direct exposure to water

Stable mounting surface or bracket; the valve should not be suspended on
plumbing or conduit connections

Avoidance of vibration

Selection of a location that will provide an operating temperature within the
specification range listed in the Components section; avoid the vicinity of
exhaust system components.
Plumbing Considerations

Check the Components section for
valve port fitting sizes, pressure
requirements, and plumbing size.

Thin-wall stainless steel tubing is
recommended.

Flareless stainless steel fittings are
recommended.

A manual shut-off valve must be
installed between the pressure source and
the valve for servicing and troubleshooting
(1/4-turn ball valve).

The tubing should include vibration
isolation loops (“pigtails”); these loops also
facilitate installation and servicing of the
valve.

The valve should be mounted as close
to the injection point as possible; lengthy
plumbing runs are more acceptable on the
higher pressure, inlet side of the valve.
