Carrier 794 - Manual (Page 28)

24 Models 750, 751, 754, 774, 794 Operating Procedures
Repeat steps 1 through 7 for the other side of the
freezer on Models 754, 774 and 794.
Disassembly
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Step 1
Remove the handscrews, freezer door(s), beater(s),
scraper blades, and drive shaft(s) from the freezing
cylinder(s). Take these parts to the sink for cleaning.
Step 2
Remove the front drip tray and the splash shield.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution (ex-
ample: Kay-5r). USE WARM WATER AND FOLLOW
THE MANUFACTURER’S SPECIFICATIONS. If
another approved cleaner is used, dilute it according
to the label instructions. (IMPORTANT: Follow the
label directions. Too STRONG of a solution can cause
parts damage, while too MILD of a solution will not pro-
vide adequate cleaning.) Make sure all brushes pro-
vided with the freezer are available for brush cleaning.
Step 2
Remove the seal(s) from the drive shaft(s).
Step 3
From the freezer door(s) remove:
S gasket(s)
S front bearing(s)
S pivot pin(s)
S adjustable draw handle(s)
S design cap(s)
S draw valve(s)
S prime plug(s)
Remove all o-rings.
Note: To remove o-rings, use a single service towel to
grasp the o-ring. Apply pressure in an upward direction
until the o-ring pops out of its groove. With the other
hand, push the top of the o-ring forward and it will roll
out of the groove and can be easily removed. If there
is more than one o-ring to be removed, always remove
the rear o-ring first. This will allow the o-ring to slide
over the forward rings without falling into the open
grooves.
Step 4
Remove the o-rings from the air tube(s) and air
orifice(s).
Step 5
Return to the freezer with a small amount of cleaning
solution. Brush clean the rear shell bearing(s) at the
back of the freezing cylinder(s) with the black bristle
brush.

Step 6
Remove the rear drip pan(s) and take to the sink for
cleaning.
Note: If the drip pan is filled with an excessive amount
of mix, refer to the Troubleshooting Guide.
Step 7
Thoroughly brush clean all disassembled parts in the
cleaning solution making sure all lubricant and mix film
is removed. Take particular care to brush clean the
draw valve core(s) in the freezer door. Place all the
cleaned parts on a clean, dry surface to air dry
overnight.
Step 8
Wipe clean all exterior surfaces of the freezer.
