CLEANING MIX LINES
The mix lines must be cleaned and sanitized whenever
changing mix or whenever the freezer is off for an
extended period of time – such as overnight, or nonbusiness
days. The mix lines are sufficiently cleaned and sanitized
when cleaning and sanitizing the pump and freezer as an
assembly.
Once every 2 weeks, if required, perform the following
steps:
A. Mix 2 gallons of milkstone remover solution according
to the directions on the container and pump through
the mix line.
B. Cut a piece of sponge slightly larger than the inside
diameter of the mix line. Place the sponge inside the
mix line and force through with tap water pressure. A
garden hose repair end clamped to the mix line works
well for this purpose.
