8600 Series _______________________________ Installation and Start-Up
1.3 Operation of the Keypad
The 8600 Series freezer has four basic modes
MODE which allow freezer setup: Run, Settings,
Calibrate and Configuration.
Run is the default mode which the freezer will normally be
in during operation.
Settings is used to enter system set points for freezer oper-
ation.
Calibrate is used to calibrate various system parameters.
Configuration allows for custom setup
of various options.
The chart below shows the selections under each
of the
modes.

1.5 Installing the Freezer
A If tippedmore than 45°, allow the unit to set
• upright
for 24 hours before start up.
To remove the freezer from the pallet, use the 7/16"
wrench to remove all the bolts securing the shipping bracket to
the pallet.
Remove the shipping bracket. Remove the ramp boards
from the pallet and place the slotted end over the ramp brackets
on the pallet. The support blocks on the ramps will be facing
down. Before moving the freezer, make sure the casters are
unlocked and moving freely. Align the caster with the ramp
boards. Use adequate personnel to roll the freezer off the pallet.
The freezer can
be easily pushed to the desired approved
location, described in Section l.5.a.
If necessary, the doors and
lower front panel may be opened to move the unit through tight
openings. When the freezer is in position, set the front caster
brakes.
The freezer must not be moved with the prod-
uct load inside.

8600 Series ______________________________ Installation and Start-Up
a. Choosing the Location
Locate the freezer on a firm, level surface in an area with
an ambient temperature between l8°C and 32°C. Provide ample
room to reach the mains disconnect switch (power switch)
located on the rear
of the freezer.
A Forproper ventilotWn and airflow, a minimum
, clearance of 5" at the rear and top and a clear-
•
ance of 8" on the side of the freezer is required.
Allow adequate space
in the front of the freezer
for door opening.
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 shelfclips 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.

8600 Series _____________________________ Installation and Start-Up
e. Remote Alarm Contacts and Analog Output
The 8600 series freezer has remote alarm contacts and ana-
log output. The remote alarm provides a NO (normally open)
output, a NC (normally closed) output and COM (common).
The contacts will trip on a power outage, high temperature
alarm or low temperature alarm. Figure 1-8 shows the
remote
contacts in alarm state.
The analog output function allows the freezer to output sig-
nals representing the temperature of the freezer cabinet. The
factory default setting is 4-20 mA. Refer to figure 1-9 for out-
put specifica-
tions.

IMPORTANT USER INFORMATION
Caution! Stored product should be
protected by an activated alarm system
capable
of initiating a timely response
24 hours/day. Alarms provide interconnect
for centralized monitoring.
f. Attaching the Power Cord
Insert the power cord into the power inlet module. Place
the retaining bracket (pIn 195763) over the connector. Tighten
retaining screws to secure.

g. Connecting the Unit
to Electrical Power
See the serial tag on the side of the unitfor electrical specifi-
cations or refer to the electrical schematics in this manuaL
The freezer should be operated on a dedicated grounded
service. Check the voltage rating on the serial tag of the unit
and compare it with the outlet voltage. Then, with the power
switch turned off, plug the line cord into the wall outlet.
First, turn on the freezer power switch. Then open the
lower front door by grasping the bottom left comer. Locate the
battery switch and turn
it on. See Figure 1-5. During initial
freezer start-up, the system battery may require charging and
the Low Battery message may appear in the message center.
&Assure the balUry switch is turned on. T1u
, rechargeable batteries require 36hours to charge
• atinitial start-up. A "Low Battery" alarm may
occur untilthe batteries are fully charged. Should
apowerfailure occur during the initial
start-up
period, the electronics will have limited operation.
1.6 Freezer Start-Up
With the freezer properly installed and connected to power,
system set points can be entered. The following set points can
be entered in Settings mode: Control temperature, high temper-
ature alarm set point, low temperature alarm set point, and
(optional) BUS set point. Default settings are shown in the table
below. See Chart
1-1 for more detail.
Control Set Point -80°C
High Temperature Alarm -70°C
Low temperature alarm -90°C
Optional SUS Set Point -60°C
If the setpoint is changed and the low temperature and high
temperature alarms are set 10°from the setpoint, the alarm
setpoints will be adjusted automatically to maintain a dis-
tance of at least 10° from setpoint.
a. Setting the Operating Temperature
All 8600 Series freezers have an operating temperature
range of -50°C to -86°C, depending on ambient temperature.
The freezer is shipped from the factory with a temperature set
point
of -80°C. To change the operating temperature set point:
1. Press the Mode key until the Settings indicator lights.

2. Press the right arrow until "HI ALM :: -XX" is dis-
played in the message center.
3. Press the up or down arrow key until the desired high
temperature alarm set point is displayed.
4. Press Enter to save the setting.
5. Press the Mode key until the Run indicator lights
or
press the right or left arrow to go to the next or previous
parameter.
If no control keys are pressed, the freezer will automatical-
ly return to RUN mode after 5 minutes.
Note: The high alarm setpoint must be set at least 10°C from
the control setpoint.
At initial start-up, the high temperature alarm is disabled
untilthe cabinet reaches setpoint or 12 hours elapse.
c. Setting the Low Temperature Alarm
The low temperature alarm will activate an audible/visual
warning when the freezer chamber temperature has reached or
decrease below the low temperature alarm set point.
To set the low temperature alarm set point:
1. Press the Mode key until the Settings indicator lights.
2. Press the right arrow until "LO ALM :: -XX" is dis-
played
in the message center.
3. Press the up or down arrow key until the desired low
temperature alarm set point is displayed.
4. Press Enter to save the setting.
5. Press the Mode key until the Run indicator lights or
press the right or left arrow to go to the next or previous
parameter.
If no control keys are pressed, the freezer will automatical-
ly return to RUN mode after 5 minutes.
Note: The low alarm setpoint must be set at least IO°Cjrom
the control setpoint.
d. Access Code
An access code of 000 is required to access the Settings,
Calibrate or Configuration modes.
If the access code is not at
the default 000, you can not leave RUN mode without entering
a code. See section 3.1.d for instructions on modifying the
access code.
1.7 Run Mode
The Run mode is the default mode for the freezer. The run
mode will display the cabinet temperature on the temperature
display and 'SYSTEM
OK' on the message center under nor-
mal operating conditions. In addition, the Run mode allows dis-
play
of the following information:
LINE VOLTAGE
COMPENSATED VOLTAGE
HSHX TEMPERATURE (heat exchanger temperature)
This information
is scrolled individually by pressing the
right arrow
key. In each case, the message center returns to
SYSTEM OK in
10 seconds if no keys are pressed.
