6.1 cUtter-griD

The cutter-grid is used to cut cubes from the ice slab formed on the evaporator. It uses low voltage, 12VAC from the transformer,
to heat the wires. Wires are warm to the touch of a hand when not under the load of a slab of ice. The cutter-grid is on only from
the start of a harvest cycle to 35 minutes from the start of the production cycle (see Section 1.1, Operation - Selector Switch in
"ON" Position).
There is no electrical repair for the cutter-grid. It will have to be replaced as an assembly. If mineral deposits have built-up on the
cutter-grid wires or frame, use Ice Maker cleaner to remove these deposits and to improve cutter-grid performance. To electroni-
cally test the cutter-grid:
• Check the resistance at the cutter-grid's plug on the outside terminals (NOTE: The middle terminal is not used). If the resis-
tance between the terminals of the plug is 5.0-5.9 ohms, the cutter-grid is good. At any other resistance readings, it will need
to be replaced.
• Check for continuity between terminals and the cutter-grid's stainless steel frame. If continuity is found, check for wires that
are not on the insulators.
Removing the Cutter-Grid:
1. Remove the escutcheon panel from inside the unit.
2. Unplug the cutter-grid from the receptacle on the side of the liner (see Figure 6.1).
3. Remove the four screws that secure the cutter-grid to the liner (see Figure 6.1).
4. Remove the cutter-grid.
Cutter-grid assembly
Installing the Cutter-Grid:
1. Reinstall the cutter-grid with the four screws.
2. Plug the cutter-grid into the receptacle on the side of the liner. Route the plug wire between the reservoir and liner (see
Figure 6.1). This will keep it away from the path of an ice slab.
3. Reinstall the escutcheon panel. Adjustment to the cutter-grid from the front screws may be necessary to align the escutch-
eon panel.

6.2 reServoir

The reservoir retains the water needed to produce an ice slab. It will hold a maximum of three quarts of water. Anything over
three quarts will be drained in the reservoir's overflow standpipe.
Anytime the reservoir is removed, it should be cleaned with ice Maker cleaner, soap, and warm water. Be sure to rinse the reser-
voir before reinstalling and clear out the drain screen when sanitizing the reservoir.
