3. FULL DRAIN FLUSH
In some hard water areas, white ice and scaling can be caused. In such case, install a
filter or softener, and change the flush mode from “partial drain flush” to “full drain flush”
according to the following instructions.
Full drain flush – After a freeze cycle ends, the unit drains all the remaining water in the
tank and refills the tank in the next freeze cycle.
Partial drain flush (default setting) – After a freeze cycle ends, the unit leaves the
remaining water in the tank and adds some water to fill the tank in the next freeze cycle.
1) Remove the screw located on the front of the water tank. Move the tank drain pipe to
the drain position (see Fig. 10). Secure the tank drain pipe with the screw.
