Sanitizing - Shake Side
Step 1
Prepare a 2- 1/2 gallon (9.5 liter) pail of cleaning/sanit-
izing solution with an active chlorine concentrate of
100 - 200 PPM (parts per million). USE WARM WA-
TER AND FOLLOW THE MANUFACTURER’S SPE-
CIFICATIONS.
Step 2
Pour the sanitizing solution over all parts in the bottom
of the mix hopper and allow it to flow into the freezing
cylinder.
Note: You have just sanitized the mix hopper and
parts; therefore, be sure your hands are clean and
sanitized before going on in these instructions.
While the solution is flowing into the freezing cylinder,
take particular care to brush clean the mix level
sensing probes, the mix hopper, mix inlet hole, the
outside of the agitator drive shaft housing, the agitator ,
the air/mix pump, pump clip, mix feed tube and cotter
pin.
Step 3
Prepare another pail of the sanitizing solution, per in-
structions in Step 1.
Step 4
Install the pump assembly at the rear of the mix
hopper. To position the pump on the drive hub, align
the drive slot in the piston with the drive crank of the
drive shaft. Secure the pump in place by slipping the
pump clip over the collar of the pump, making sure the
clip fits into the grooves in the collar.
