MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
In order to shut off one or more sections of the boom, switch one or more
unneeded boom distribution valves
B
to off position. The constant
pressure device ensures that the pressure does not increase in the
sections which are still operating.
In case of electrical failure it is still possible to manually overide all
functions of the operating unit. To operate manually, disconnect the
multiplug from the ESC control box first and operate the handles by hand.
It is possible to change pressure, turn boom sections on or off, or shut off
the complete control unit manually.
IMPORTANT:
When the sprayer is stored, the EC control box and the
multiplug must be protected against moisture and dirt. A plastic bag
may be used to protect the multiplug. Store the control box in a
clean dry place.
6.9 Agitation Adjustment (Agitation nozzles only)
Agitation is necessary to keep the solution in your tank properly mixed.
Consult your chemical
supplier for the recom-
mended amount of
agitation.
In general, maximum
agitation is required but
some products tend to
foam easily. To reduce
foaming in some in-
stances
anti-foaming agents
may be added to the
tank (Refer to chemical
label). When running
low liquid levels in the tank, agitation may be reduced to facilitate pump
priming and avoid pressure fluctuations. Make sure that you have ad-
justed the agitation properly before sprayer calibration.
Turning the Agitation Valve A clockwise will reduce the agitation flow.
Turning the valve counter clockwise will increase the agitation flow.
