Note: Replacing the bearing needs a fitting tool. If it is not available, replace the whole
extruding head.
AUGER
9) Lift out the auger. Check the top and bottom areas in contact with the bearings. If the
surface is scratched or pitted, replace the auger. Check the blade edge of the auger. If it
is scratched or worn where it has contacted the evaporator, replace it.
EVAPORATOR
Note: Skip the following steps 10) through 15) when the evaporator does not need
replacement.
10) Recover the refrigerant and store it in a proper container, if required by an applicable law
(See "2. [b] REFRIGERANT RECOVERY").
Always install a new drier every time the sealed refrigeration system is opened. Do not
replace the drier until after all other repair or replacement has been made.
11) Remove the bulb of the expansion valve.
12) Disconnect the brazing connections of the expansion valve and the copper tube - low
side from the evaporator, using brazing equipment.
Always protect the valve body by using a damp cloth to prevent the valve from
overheating. Do not braze with the valve body exceeding 120°C.
13) Disconnect the hoses from the evaporator.
14) Remove the four socket head cap screws securing the evaporator with the housing.
15) Lift off the evaporator.
HOUSING AND MECHANICAL SEAL
16) The mechanical seal consists of two parts. One part rotates with the auger, the other is
static and is fitted into a top recess in the housing. If the contact surfaces of these two
parts become worn or scratched, the mechanical seal may leak water and should be
replaced.
17) Remove the O-ring on the top outer edge of the housing.
