Built-In Use & Care 18 Ice Maker Operation The ice maker in your Sub-Zero freezer is fully automatic and has been tested at the factory. To start making ice, activate the ICE MAKER key pad on the control panel. IMPORTANT NOTE: The ice maker system will continue to operate even if the ice container is not in place. When removing the ice container for an extended period, deactivate the ice maker by pressing the ICE MAKER key pad on the control panel. ICE PRODUCTION The automatic ice maker is designed to produce enough ice for normal family use. The timing of ice making cycles will vary depending on load conditions, door openings and room temperature. On average, you can expect a cycle of ice (eight cubes per cycle) every two hours until the container is full. The ice maker operates on water pressure of 35 psi (2.8 bar) to 120 psi (8.2 bar). In some cases, a reverse osmosis water filter system may not be able to maintain the minimum pressure. IMPORTANT NOTE: If ice is not used regularly it tends to fuse together. To avoid this, empty and replace the ice in the container as needed. MAX ICE FEATURE The max ice feature increases the rate of ice production for times where you need more ice than normal. The increased ice production will last for 24 hours, at which time it will return to the normal production level. You can expect about a 40% increase in ice production when this feature is turned on. To initiate the max ice feature, press the MAX ICE key pad on the control panel. The indicator will be visible in the control panel display. Refer to the illustration below. To turn off the max ice feature, simply press the MAX ICE key pad again and the unit will return to normal ice production. MAX ICE KEY PAD Max ice key pad.
