Armature and Isoplate
NoTe:
Replacement armatures are normally supplied complete with isoplates from the
factory. The isoplate is available separately should this be the only component requiring
replacement in this subassembly.
Removing the Armature and Isoplate
To remove the armature (1), proceed as follows (see Figure 1):
The unit should be disconnected from the power supply and the cover removed.
1. Drain the reservoir.
2. Carefully cut the cable ties (3) securing the thermocouple leads (4), the microswitch leads (5)
and the reservoir sensor leads (6).
3. Remove the microswitch leads from controller board (7) terminal positions labelled CASSIN
J4-1 and J4-2.
4. Loosen the two screws (8) holding the steam generator bracket (9) to the chassis (10).
5. Disconnect the compression nut (11) holding the steam generator outlet tube (12) to the inlet
probe fitting (13).
6. Disconnect the compression nut (14) holding the solenoid valve inlet tube (15) to the outlet
probe fitting (16).
7. Loosen the two screws (17) that attach the solenoid valve bracket assembly (18) to the
chassis.
8. The probe bracket assembly (19) is held by four cap screws with washers. Remove all screws
(20) with washers using a 9/64-inch ball end Allen key. Note the ground strap (21) attached to
the bottom right of the probe bracket by the cap screw.
9. CAREFULLY bend the thermocouple leads away from the armature.
10. Tilt the unit on its side so that the reservoir and PCB are facing upwards. Remove the four cap
screws with spring lockwashers (22) securing the armature to the chassis using an Allen key:
two at the front on the bottom of the chassis, and two at the rear on the bottom of the chassis.
11. Lower the unit to the flat work surface and lift the armature from the chassis. Be careful not to
damage the thermocouple in the probe bracket assembly
.
