Czt Storage Drawers - Maytag Built-in Refrigeration Manual

Fresh Food Interior
( )Elevator Shelf (max 4)
( )Standard Shelf (max 4)
( )A la Carte Drawer (max 2)
( ) Total (max 4 plus the 2 Climate Zone drawers that are always included)
The maximum number of bins in the fresh food door is four. Looking at the chart, if there
are four pickoff bins in the fresh food door, it is not recommended to add a dairy bin.
The maximum number of shelves in the fresh food section is four. If there are two A la
Carte drawer shelves, there should only be two other shelves installed. If there are four
elevator shelves installed the consumer has reached their maximum.
When considering the freezer interior, the recommended number of shelves are in
addition to the two wire baskets that are already included with the base models.
One of the biggest airflow issues would arise from adding too many A la Carte storage
drawers. It is recommended that no more than two A la Carte drawers be installed.

CZT Storage Drawers

The Climate Zone drawers are like having two additional mini-refrigerators in the fresh
food compartment. The temperature of these drawers can be controlled independently of
the fresh food compartment temperature. There are three settings for the top Climate
Zone drawer. The first setting is "Off" or the same temperature as the fresh food
compartment. The second setting is "Citrus" which will maintain a CZT temperature of
38°F while the third setting is "Produce" or 34°F.
The lower CZT drawer adds the setting of "Meat" that will provide temperature control at
31°F.
It is possible to have the CZT set at a higher temperature than the fresh food section. To
maintain the higher temperature, a small foil heater is included. With the combination of
a dedicated temperature monitoring thermistor, an independent damper and a circulation
fan, temperature control in the CZT module will be within one degree of the set
temperature.
Condensation has always been a problem in crisper drawers. This is one of the main
advantages of the Climate Zone drawer over a crisper drawer. The cabinet air does not
flow through the drawer itself. The cooling air flows around the drawer in an outer jacket.
Part of the inner liner is a polymer film. This film is sensitive to humidity levels. If the
humidity inside of the drawer gets excessive, the pores in this film expand and let the
moisture out. This moisture will condense on the evaporator coil and be removed during
defrost. When the humidity levels are in the correct range, the pores in the polymer will
close.
