^ The suction pipes should be cleaned
through with water.
^ Place the suction pipes in a container of
hot water (40 - 50°C).
^ Then use the dispenser calibration system
to operate each pump until the dispensing
system is thoroughly flushed through.
^ After reconnecting all parts check all
connections, hoses, dispensers and seals
for leakages.
