the mix hopper. Place the cotter pin in
position in the outlet fitting of the pump.
Figure 152
18. Remove the restrictor cap and the syrup
hole plugs.
19. Return to the freezer with a small amount
of sanitizing solution. With a pail below
the door spout, dip the door spout brush
into the sanitizing solution and brush
clean the syrup ports in the freezer door,
door spout, bottom of the driven spinner
and spinner blade, and syrup line fittings.
Note: To assure sanitary conditions are
maintained, brush clean each item for a total
of 60 seconds, repeatedly dipping the brush in
sanitizing solution.
20. With the syrup port brush, brush each
syrup port hole 10 to 15 times. Dip the
brush in sanitizing solution before
brushing each port.
21. Fill the squeeze bottle with sanitizing
solution. With a pail beneath the door,
insert the tube end of the squeeze bottle
into the syrup port, and squeeze the bottle
firmly. This action will force solution out of
the adjacent port and down around the
spinner. This procedure should be
performed for at least 10 seconds per
port.
22. Install the syrup valves and the restrictor
cap.
Sanitizing - Soft Serve Side
1. Prepare 2.5 gallons (9.5 liters) of McD
Sanitizer (HCS) solution. Use one packet
in 2.5 gallons (9.5 liters) of water (100
PPM).
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 housing, the agitator, the
air/mix pump, pump clip, mix feed tube
and cotter pin.
3. Install the pump assembly at the rear of
the mix hopper. To position the pump on
the drive hub, align the drive hole in the
piston with the drive crank of the drive
shaft. Secure the pump in p lace by
slipping the pump clip over the collar of
the pump, making sure the clip fits into the
grooves in the collar. (See Figure 153.)

4. CAUTION!
Install the pump end of the mix feed
tube and secure with the cotter pin.
Failure to follow this instruction could
result in sanitizer spraying on the
operator.
