a. Choosing the Location
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.
b. Installing the Wall Bumpers
The parts bag, located inside the cabinet, contains the fol-
lowing 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.
c. Installing the Shelves
Install the shelf clips into the shelf pilasters (front and
back) at the desired shelf level. Install the shelves in the cabinet
onto the clips.
NOTE:
On units having the optional 5 inner door option, refer
to the instructions accompanying the inner door kit.
d. RS-232 Communications
The 8600 series freezer has a data communications inter-
face. The factory default setting is RS-232.
The wiring identification for the interface is shown in
Figure 1-7. 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 serial device. Some serial devices may
require a null modem adapter.
Data format:
Baud

Data bits
8 (7 bit ASCII with leading zero)
Start bits

Stop bits
2
Parity

The data transfer sequence is transmitted in the following
format. X refers to numerical temperature data.
(NUL) (-) XXX (SP) C (SP) (OVERTEMP) (SP) (LF) (CR)
(EOT) (SP) (UNDER TEMP)
The words "OVER TEMP" or "UNDER TEMP" are
transmitted when an alarm condition exists along with the tem-
perature. If no alarm condition exists, spaces will be sent. A
total of 20 characters will be sent.
SP - Space
