Built-In Use & Care
Vacation Time
For extended vacations, shut off power to the built-in unit.
Empty the unit and block the doors open slightly. A one-
inch space will let fresh air in to keep the interior dry and
fresh. Upon return, the water filter should be discarded
and replaced with a new filter before start up.
For short vacations, remove all perishable items. Shut off
the ice maker and empty the ice container. Do not change
the electronic control settings.
If your religious observances require turning off the lights
and ice maker, refer to Sabbath mode on page 15.
Be sure to block doors open when the unit is not in
service to avoid the buildup of moisture, which could
attack metal interior surfaces.
