Boom Shut-off Valves
Plumb boom valves with flow-through port as shown. Boom
valves of differing designs may require a “T” fitting. Make
certain to use adequately sized plumbing lines to avoid
ex ces sive pressure drops. DO NOT install the shut-off valves
closer than 12” to the flowmeter.
Locate the boom shut-off harness. The boom wires are color-
coded. (If valves have wires, crimp terminals on those wires.)
Attach the cables to the terminals on the boom valves.
Attach a ground terminal to each valve. If valves operate
backwards, reverse connections. Apply silicone grease to the
ter mi nal connections to help prevent corrosion and insure a
good electrical con nec tion.
IMPORTANT NOTE: See complete wiring diagram on page 8.
NOTE: To configure your system using motorized ball
valves, see Appendix B.
RELIEF SOLENOID
Illustration 10
The relief valve is used to “dump” pressure when your boom
valves are turned off. Whenever all the boom control switches
are turned off, or when HOLD is selected with the master
switch, the relief valve should be open. Use this plumbing
illustration
(See Illustration 10)
as your pattern for proper
installation if your relief valve has a flow-through port.
DO
NOT
install the relief valve closer than 12” to the flowmeter.
With the relief valve installed, locate the violet wire (tied
back on flow/servo cable) and crimp a female terminal on
the violet wire and connect to relief valve terminal. Connect
other terminal on relief valve to ground.
If your relief valve does not have flow-through port, you must
add a “T” fitting.
See Illustration 11.
NOTE: To as sure a good con nec tion and avoid corrosion,
coat electrical connections with sil i cone grease.

Care and Maintenance of your MT-3405 F
CONSOLE
Store the console in a cool dry location if it will not be
used for an extended period of time, such as during the
off-season.
As with any electronic equipment, use care in cleaning
so that water or other liquids do not enter the case.
Thoroughly rinse Flowmeter with clean water, install
plastic shipping plugs and keep from freezing.
PRECAUTIONS
•
The input pressure on the glass-filled nylon
flowmeter FM750 GFN should not exceed 100 PSI
(689 kpa).
•
Do not expose the flowmeter to liquid temperatures
exceeding 130 degrees F (55 degrees C).
•
Some chemicals may damage the PPS turbine or
the nylon body of the flowmeter. If you are in
doubt, contact the chemical manufacturer.
