3. If the product has Y-tubes, shut off the gates at all of
the Y-tubes.
4. Turn on the air fan and let it run. Use the
“SPLIT AIR -” softkey
a
to reduce the regulated air
pressure to a low value, 1 inch water pressure
or less - this diverts most of the air to the bulk seed
delivery system.
Reduce fan speed as necessary to obtain a low
meter pressurization.
Clean out meters with fan running. Work from one side of
the implement name to the other.
Meter Clean-Out
When planting is completed, it is commonly the case that
some seed remains. There may be seed in the hoppers,
hose lines, and meters.
The product includes an 817-811C container for meter
clean-out, stored in a spring-loaded holder at the right
rear of the air manifold. The container can hold all the
seed in the meter and inlet (up to a closed slide gate).
The container can be converted into a true funnel for
complete system clean-out.
The hoppers are connected to the rows with clamped
hose, and are not intended to be routinely unlatched
and tipped for clean-out.
Funnel Conversion
Materials and tools needed:
•
a length of 1
1
/
2
inch I.D. hose
•
a worm drive clamp with a working diameter of
approximately 1
1
/
2
to 2
1
/
4
inch
•
a hacksaw
b
with fine-toothed blade
Trim the sump from the funnel. Slide the hose fully
onto the funnel tip. Secure with clamp (do not
-over-tighten clamp, the funnel wall be crushed).
The choice of complete system clean-out process
depends on whether you are using the 817-811C as a
container or funnel.
a. The “FILL METER” function can divert all the air to seed delivery, but only does so for a short period of time (~90 seconds).
