Operating Procedures
Models 345, 346, and 355 contain two 7 qt. (6.6 L)
freezing cylinders. Model 349 contains four 7 qt. (6.6 L)
freezing cylinders.
CAUTION! This machine is pressurized when
in operation. The control switch, located on the top side
of the control box must be in the OFF position until the
machine is completely assembled. No part should ever
be removed from the machine while it is in operation. No
parts should be removed until the control switch has
been turned to the OFF position and all pressure has
been relieved at the draw handle.
The syrup flow controls combine the two ingredients of
soda water and syrup, and send this combination to the
mix hoppers. As product is drawn, new product from the
hopper will flow through a mix feed tube down into the
freezing cylinder. The mix hopper is supplied with 20 lb.
of CO
2
gas for dispensing the finished product.
We begin our instructions at the point where the parts are
disassembled and laid out to air-dry.
The following procedures will show you how to assemble
the parts into the freezer, sanitize them, and prime the
freezer with fresh product.
Duplicate the following procedures, where they apply, for
the remaining freezing cylinder(s).
If you are disassembling the machine for the first time or
need information to get to this starting point in our
instructions,
(See Disassembly on page 6-12.)
Assembly
WARNING! Make sure the power switch is in
the OFF position. Failure to follow this instruction may
result in severe personal injury from hazardous moving
parts.
Note: When lubricating parts, use an approved
food-grade lubricant (example: Taylor Lube HP).
1. Slide the O-ring into the first groove on the driveshaft.
Lubricate the groove, O-ring, the area where the boot
seal snaps onto the driveshaft, and the shaft portion
that comes in contact with the bearing on the beater
driveshaft. Do not lubricate the hex end of the
driveshaft.
Slide the seal over the shaft and groove until it snaps
into place. Pinch the boot seal and fill the inside
portion of the seal with 1/4 in. more lubricant.
Figure 6-1
2. Insert the driveshaft into the freezing cylinder (hex
end first) and into the rear shell bearing, until the seal
fits securely over the rear shell bearing. Make sure
the driveshaft fits into the drive coupling without
binding.
