CHANGING COLORS
1. Run the pump in REVERSE to empty the tube of color.
2. Remove pump tube from pump head.
3. Remove poly-tubing from process machine and coil entire tube onto top of drum. Do not
disconnect any other fittings. Tape up the open end of the poly-tubing to prevent dripping of
color.
4. Bring in next color drum and repeat Steps 5 through 8 of "Start Up Procedure".
PICKUP ASSEMBLY
An inexpensive pickup assembly is fitted to the drum of color to be used. If one pump is going to
run more than one color, each color drum should be equipped with its own pickup assembly. Each
pickup assembly consists of several components. All are connected together and should never be
disassembled except in the case of a tube blockage caused by contaminants in the liquid color.
The lance and threaded adaptor are installed directly into the lid of the drum. The other end of the
tubing assembly is connected to the feed throat of the process machine.
A common source of problems comes from contaminants, such as plastic pellets entering the
liquid. When opening a new drum or replacing an empty one, be certain that no openings are left
uncovered where contaminants could accidentally enter the liquid.
Tubing assemblies for 30 and 55 gallon drums are fitted with a High Capacity Filter that reduces
the possibility of plastic pellets clogging the pump tube. It is easily cleaned by back flushing with
water.
If a pickup assembly is available for every color, operators should never need to come in contact
with the liquid color except when replacing an empty drum. The REVERSE switch allows the
operator to momentarily run the pump in reverse to drain liquid from the tube assembly back into
the liquid container. Since there is no cleanup required for a color change and no color is
discarded or lost, a considerable amount of coloring is saved over a period of time.
