EPLACEMENT NSTRUCTIONS
1. Disconnect the icemaker from the power and water supplies.
2. Remove the top, front, and side panels in that order.
3. Recover the refrigerant from the icemaker using appropriate recovery techniques.
4. Drain the water from the evaporator by disconnecting the water feed line at the bottom of the
evaporator.
5. Remove the dispense tray cover and pull the auger assembly out of the evaporator. Set the cover
and assembly aside.
6. Remove the dispense tray assembly by loosening the screw clamp and pulling the tray off of the
evaporator. Retain this assembly for reuse.
7. Remove the insulation from the refrigerant lines at the expansion valve, at the inlet side of the
evaporator and the suction line, and at the outlet side of the evaporator, exposing the solder joints.
If the insulation is dry and undamaged, it can be re-used.
8. Protect the expansion valve from excessive heat by wrapping it with a cold wet rag or a commercial
heat protection product. Heat the joint between the valve and the evaporator inlet until it is hot
enough to separate, and then remove the expansion valve from the evaporator inlet. Separate the
suction line from the evaporator outlet in a similar manner.
9. Heat and remove the refrigerant filter dryer from the liquid line. Do not install the new dryer until
after the new evaporator assembly is installed.
10. Use a 7/16" wrench to un-bolt the base of the evaporator from the gear motor. Gently pry the base
upward and lift the evaporator off of the gear motor. Dispose of the evaporator per the current
warranty procedure.
11. Inspect the gear motor shaft seal for signs of leakage or damage. Replace as required. Lubricate
the shaft seal rubber with a food grade lubricant.
12. Place the new evaporator on the gear motor shaft seal. Carefully rotate the evaporator until the inlet
and outlet tubes are in the same location as they were with the previous evaporator. Apply anti-
seize (Loctite Silver Grade Anti-seize #76764) on the bolt threads, install the lock washer, and bolt
the evaporator to the gear motor.
