5.Removal and Replacement of Mechanical Seal and Lower Housing 5a. Mechanical Seal

1)Move the control switch to the "DRAIN" position and drain all of the water from the evaporator.

2)After the water has stopped draining, move the control switch to the "OFF" position, then turn off the power supply. Remove the front and top panels, then move the power switch to the "OFF" position.

3)Remove the front cover of the storage bin. Remove spout B, then remove spout A. See Fig. 1.

4)Remove the apron panel, then remove the left side panel.

5)Remove the extruding head heater and the allen head cap screws securing the extruding head.

6)Using the cutter, lift out the auger assembly, then remove the evaporator bracket.

7)The mechanical seal consists of two parts. One moves along with the auger, and the other is fixed on the lower housing. If the contact surfaces of these two parts are worn, cracked, or scratched, the mechanical seal may cause water leaks and should be replaced.

8)Remove the allen head cap screws securing the evaporator to the lower housing.

9)Raise the evaporator up to access the lower housing.

10)Remove the mechanical seal from the housing. If only replacing the mechanical seal, proceed to step 13.

CAUTION

To help prevent water leaks, be careful not to damage the surfaces of the O‑ring or mechanical seal.

11)Remove the O-ring and the bolts securing the housing to the gear motor and remove the housing from the gear motor. If inspection of the upper bearing inside the extruding head (see "V.D.1. Upper Bearing Wear Check") indicates that it is out of tolerance, replace both it and the bearing inside the lower housing.

Note: Replacing the bearing requires a bearing press adaptor. If one is not available, replace the whole extruding head and housing.

12)Install the O-ring and mount the lower housing on the gear motor.

13)Install the lower part of the mechanical seal on the lower housing.

14)Lower the evaporator down and secure it to the lower housing.

15)Install the auger assembly with the upper part of the mechanical seal attached.

16)Replace the evaporator bracket in its correct position.

17)Replace spout A, spout B, and the front cover of the storage bin in their correct positions.
