Models 750, 751, 754, 774, 794 Operating Procedures
Section 6 Operating Procedures
The Model 751 has been selected to illustrate the
step-by-step operating procedures for all models
contained in this manual. These models, for all
practical purposes of operation, are the s ame.
Each unit stores mix in a hopper. The mix then flows
by gravity through an air tube down into the f reezing
cylinder. They all have 3.4 quart (3.2 liter) capacity
freezing cylinders. The Models 750, 751, 754, and 774
have 20 quart (18.9 liter) mix hoppers. The Model 794
has 14 quart (13.2 liter) mix hoppers.
Duplicate the following procedures, where they apply,
for the second freezing cylinder on Models 754, 774,
and 794.
We begin our instructions at the point where we enter
the store in the morning and find the parts
disassembled and laid out to air dry from the previous
night’s cleaning.
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation to
serve y our f irst portion.
If you are disassembling the machine f or the first time
or need information to get to this starting point in our
instructions, turn to page 24, “Disassembly”, and start
there.
Prior to Set-Up (Model 774)
Step 1
Remove the two stainless syrup jars with topping
pumps from the syrup rail. Check the water level in the
heated syrup topping well. Make sure the water isfilled
to the indicating mark on the bottom of the well. The
heated rail s hould have 32 oz. (946.2 ml) of water .
Step 2
Place the heater switch in the ON position.
Note: This heating process will take approximately
2-1/2 hours to reach temperature. The water level in
the topping wells must be checked at least once daily.
Step 3
Prepare apail of anapproved 100 PPM sanitizing solu-
tion (example: Kay-5r). USE WARM WATER AND
FOLLOW THE MANUFACTURER’S SPECIFI-
CATIONS. S anitize the topping pumps by placing the
entire pump a ssembly in the pail of sanitizing solution.
Pump the solution through the assembly to thoroughly
sanitize the pump.
Step 4
Remove the two topping pumps. Fill each stainless
syrup jar with topping. Replace the topping pumps in
the syrup jars.
Assembly
Note: When lubricating parts, use an appr oved f ood
grade lubricant (example: Taylor Lube).
MAKE SURE P OWER SWITCH IS IN THE
“OFF ” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Step 1
Install the dr ive shaft. Lubricate the groove and shaft
portion that comes in contact with the bearing o n the
beater drive shaft. Slide the seal over the shaft and
groove until it snaps into place. DO NOT lubricate the
hex end of the drive shaft. Fill the inside portion of the
seal with 1/4” more lubricant and lubricate the flat side
of the seal that fits onto the r ear shell bearing.
