PPE a .
7. Verify that the nurse tank hose withdrawal valve
is closed. Hand tighten only. Do not use tools.
8. Verify that any hose valves ( , not shown here)
are also closed. Hand tighten only. Do not use tools.
9. Check for signs that there may be residual NH
3
in
between the Acme plug and the outlet shut-off valve:
• strong ammonia odor
• hissing of escaping gas
• fitting getting cold
• dripping or spraying fluid
If there are any signs of residual NH
3
, leave the plug
in, but loose, until the ammonia has vented, and the
Acme fitting has re-warmed to ambient temperature.
This could take tens of minutes if the cart was
improperly configured during or after filling.
10. Disconnect the outlet end of the hose from the
Acme parking plug, or remove the Acme plug.
Inspect the outlet Acme threads. Clean away any
debris or other contamination.
Refer to Figure 33
11. Route the cart hose along the cart tongue, securing
it to any clamps or caddies provided.
Do not clamp or tie the hose within 3 feet (92 cm) of
the breakaway coupler inlet
.
Allow at least 13 inches (33 cm) slack in the hose
within the first 3 ft. Do not allow excess slack that
could allow the hose to snag or drag on the ground.
12. Bring the hose outlet and applicator inlet
into contact. Hand tighten the swivel collar or shroud
on the hose fitting. Do not use tools. You only need
to adequately compress the gasket in the applicator
inlet.
NH
3
: Dry Run
Before activating the NH
3
delivery, cautious practice is to
make one dry run pass, including a turn in each
direction. This assures that tine depth is set correctly,
hydraulics are working correctly, the nurse tank cart is
tracking without issue, proper slack exists for all hoses
and harnesses, and the meter console is reporting
correct field speed.
