To Replace the Evaporator:
(Assuming all the steps for removal of the thrust
bearing, breaker, auger, and water seal have been
performed.)
1. Shut the hand valves in the liquid and suction
lines to the evaporator being serviced; then
discharge the refrigerant.
2. Unsweat the refrigerant connections:
a) At the thermostatic expansion valve outlet.
CAUTION
Heat sink the TXV body when unsweating or
resweating the adjacent tubing.
b) At the suction line at the joint about 3" from the
evaporator.
3. Remove the
evaporator.
4. Unsweat the drier
from the liquid line.
5. After installing a
new water seal in the
new evaporator (see
"To Replace the
Water Seal") sweat in
the new evaporator at
the old connections.
6. Install an new drier
in the liquid line.
7. Evacuate the
system until
dehydrated, then
weigh in the
nameplate charge.
Check for leaks.
8. Install auger,
breaker, breaker
bearing assembly,
and ice discharge
chute in reverse order
of disassembly. See
"To Reassemble
Evaporator and Auger"
To Reassemble the Evaporator and Auger
1. After the gearmotor has been inspected, fasten
the evaporator to the gear motor, torque the bolts
to 110 inch pounds.
2. Lower the auger into the evaporator barrel,
slightly turning it to match up with the drive end.
Do Not Drop Into the Evaporator.
3. Complete the reassembly by reversing the
disassembly for the breaker & thrust bearing
assembly.
