7.4 Sliding Window Replacement & Manual Adjustment
The sliding window replacement is accomplished by removing the front decorative panel, control center, and window glide
assemblies. The sliding window adjustment may be required due to everyday use over the life of the cabinet. Both the
right and left window glides are adjustable by a set screw and tension screw method. When adjusting the sliding window,
be sure to verify proper micro switch operation. If the sliding window is too loose, the sliding window will not properly
activate the micro switches, thus causing potential operational malfunctions to occur. In addition, the sliding window
retention or ability to slow the rate of fall, if a window counterbalance experiences a fault, is also required to assure proper
window function (see Sliding Window Retention Verification in the Inspection Report).
7.5 Airflow Control System Setup and Calibration
7.5.1 General
The operation of the NU-581 cabinet requires that the setup and calibration procedures be performed in order to
certify or commission the cabinet for usage. The setup and calibration procedures performed ONLY BY THE
CABINET CERTIFIER ensure that cabinet's setpoints are verified and that the airflow monitor sensors are calibrated
to read the correct values. Press MENU to access Calibration/Service parameter.
Entry into the Calibration/Service functions requires a service password for entry. After pressing the
Calibration/Service menu item, a password screen will appear. The default password is “9876”
Once the service password is entered, the Calibration/Service menu will appear.
