5. Swing the caps over the outlet nozzle on both sides of the car and lock in place with a
quarter (¼) turn of the fasteners (you may need to hit the cap with the palm of your hand
for the fasteners to engage the holes).
Railcars with P-4300 Outlets
Use Style B nozzle cap.
• Attach the adapter assembly to this cap with the three socket-head screws provided.
Remove both end caps from the near and the far side of the car bottom on the section to be
unloaded. The filter should be fitted on the far side port with the opening down to prevent
contamination.
• Seat the #2 probe with the male quick-change coupling assembled to it into the adapter and
work the probe through the material, keeping the probe close to the bottom of the railcar
port. Hand-tighten the thumb screw on the nozzle cap when the probe is in as far as
possible. Attach the female quick-change coupler on the flexible material tube to the male
coupler on the probe and begin conveying (see Operation Section for proper car unloading
adjustment).
For complete material removal after most material is emptied, read Final Clean Out
instructions for the P 5400 ACF outlet in the previous section.
Chemo-O-Vac Car (Pullman Standard)
Use Style “B” Nozzle Cap.
1. Attach the adapter assembly with the three socket-head machine screws provided. Install
the #3 (shortest) pick-up probe in the adapter assembly. Fit the filter to the port opposite
the one to be unloaded with the opening down to prevent contamination. Tighten the
thumb screw by hand.
2. Remove the seal and protective cap from the unloading side of the railcar. Work the
probe through the material in the railcar nozzle, keeping it against the baffle. You can
rotate the installed position of the probe connection from the upright position with the
probe against the baffle. Keep the probe against the baffle for proper material pickup.
3. Hand-tighten the thumb screw on the nozzle cap.
4. Attach the female quick-change coupler on the flexible material tube from the system to
the male coupler on the adapter assembly.
5. See Chapter 8 on Page 57 for proper car unloading adjustments.
6. For complete material removal after most material is emptied, read the instructions in the
previous section.
7. Once the compartment is emptied, replace caps and repeat on other compartments.
