Rear panel
This illustration identifies the main features of the rear panel:
ill 4913
These are the following:
Drain
The drain port is the exit point where sample/dispersant leaves the dispersion unit.
A warning triangle warns that the contents of the tank are drained from this pipe.
The risk depends on the hazardous nature of the dispersants/samples being meas-
ured.
The drain pipe should not exceed 2m in length, must run downwards and should
have no loops or kinks.
Dispersant input port
The dispersant input is the inlet port which is connected to a clean source of dis-
persant. A warning triangle warns that the dispersant may be hazardous, though for
most applications it will be water.
Air purge inlet
If using a particularly aggressive dispersant, this may cause the grease in the pump
motor bearings to leach out. If this may be a problem, the air purge inlet port can be
used to connect an air supply. This will keep fumes away from the bearings. The air
supply must be maintained at all times when aggressive dispersants are used;
Appendix A gives the purge air supply specifications.
