Locate the freezer on a firm, level surface in an area with an ambient
temperature between 18°C and 32°C. Provide ample room to reach the
mains disconnect switch (power switch) located on the rear of the freezer.
Note For proper ventilation and airflow, a minimum clearance of 5" at the
rear and front and a clearance of 8" on the side of the freezer is required.
Allow adequate space for lid opening. If ambient increases above 36°C,
clearance at the rear of the cabinet must be increased to 8".
The parts bag, located inside the cabinet, contains the following parts.

Install the bolts into the pre-tapped holes on the back of the compressor
section. Install a neoprene cap on each bolt. Refer to Figure 1-2 for the
locations of the pre-tapped holes.
Revco CxF freezers have a data communications interface. The factory
default setting is RS-232.
The wiring identification for the interface is
shown in Figure 1-10. One nine pin, sub
"D" style connector is located on the back
of the freezer. See Figure 1-2 for the
location of the connector on the freezer.
The freezer transmits temperature information every 60 minutes. A
standard DB9 serial extension cable can be used to connect the freezer to a
serial device. Some serial devices may require a null modem adapter.
