Emptying the Waste Hopper
NOTE: You may choose to have a single, shared scrap drum for the feed center and the
booth after filter. In this application, the scrap transfer hose may remain connected to the
scrap drum at all times, allowing you to frequently empty the feed center waste hopper to
keep the powder level down.
1. See Figure 6-1. Secure the waste lid to an empty 55-gallon drum (3).
2. Connect the ground clamp (4) to a true earth ground.
3. Attach a 3/4-in. transfer hose (2) between the transfer pumps (5) and the waste lid.
Use hose clamps on both ends of the transfer hose.
NOTE: Make sure that all unused hose connectors on the waste lid are plugged.
4. Attach the vent hose (1) to the waste lid vent stub. Attach the other end of the vent
hose to the vent stub (6) on the feed center.
5. Touch the WASTE PUMPS START button on the Manual Feed Center Control,
page 1 menu. The fluidizing and flow air will turn on and the powder will be drawn out
of the waste hopper.
NOTE: The normal operating air pressure for the transfer pump is 2.75 bar (40 psi). The
normal fluidizing air pressure is 0.5 bar (8 psi). Adjust the air pressures as needed at the
feed center control panel.
6. When the transfer pump is not drawing any more powder out of the waste hopper,
touch the WASTE PUMPS STOP button.
NOTE: The waste transfer process will automatically stop after several minutes. The
duration of the waste transfer process may be changed on the Feed Center Setup
menu.
