Section 2
Installation and Start-Up
Locate the refrigerator on a level surface in an area of 23°C, ±5° ambient
temperature fluctuation.
Allow eight (8) inches of clearance above the cabinet and three (3) inches
of clearance at the back and sides of the refrigerator. This space is necessary
to allow adequate airflow around the refrigeration system.
For better cabinet stability when the drawers are extended, adjust the
leveling feet so that the front of the cabinet is about 1/4” higher in the
front.
The Performance Alarm/Monitor (Figure 2-2) is a standard feature on
Blood Bank Refrigerators. Operating procedures for the monitor are
located in Section 3 of this manual.
To assure continued monitoring during a power outage or if the
refrigerator is intentionally unplugged, a back-up battery is on the printed
circuit board (part number 400116). Refer to Figure 2-4.
Note This battery is shipped in the Performance Alarm/ Monitor and must
be connected before connecting the unit to AC power. ▲
