The 700 Series freezer has five basic modes which allow freezer setup and
operation. Press the Mode key to scroll through the mode selections.
Up Arrow: Increases or toggles the parameter value.
Enter: Must press Enter key to save to memory all changed
values.
Down Arrow: Decreases or toggles the parameter value.
Silence Key: Press to silence the audible alarm. See Section
4 for alarm ringback times.
Note If tipped more than 45°, allow the unit to set upright for 24 hours
before start up. ▲
To remove the freezer from the pallet, use a 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 the following section. When the freezer is in position, set the
front caster brakes.
Note The freezer must not be moved with the product load inside. ▲
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 freezer. Install
a neoprene cap on each bolt. Refer to Figures 1-3 and 1-4 for the locations
of the pre-tapped holes.
See Figures 1-3 and 1-4 for the location of the remote alarm contacts. The
remote alarm connector is located in the parts bag provided with the
manual. It must be installed if connecting the freezer to an alarm system.
After installing the wiring from the alarm system to the connector, install
the connector to the freezer microboard and secure with the two screws
provided. 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
1-10 shows the remote contacts in alarm state.

Insert the power cord into the power inlet module. Place the retaining
bracket (P/N 195763) over the connector. Tighten retaining screws to
secure.
Note See the serial tag on the side of the unit for electrical specifications 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 corner. Locate the battery switch and turn it to
Standby mode ( ). See Figures 1-3 and 1-4. During initial freezer start-up,
the system battery may require charging and the Low Battery message may
appear in the message center.
Note Assure the battery switch is turned to Standby mode ( ). The
rechargeable batteries require 36 hours to charge at initial start-up. A “Low
Battery” alarm may occur until the batteries are fully charged. Should a
power failure occur during the initial start-up period, the electronics will
have limited operation. ▲

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 temperature alarm set point, low
temperature alarm set point, and (optional) BUS set point. Default settings
are shown below.
Note If the set point is changed and the low temperature and high
temperature alarms are set 10° from the set point, the alarm set points will
be adjusted automatically to maintain a distance of at least 10° from set
point. ▲
The freezer has 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 Set Temperature indicator lights.
2. Press the up/down arrow key until the desired temperature set point is
displayed.
3. Press Enter to save the set point.
4. Press the Mode key until the Run indicator lights for Run mode.
If no keys are pressed, the freezer will automatically return to RUN mode
after 5 minutes.

The high temperature alarm will activate an audible/visual warning when
the freezer chamber temperature has reached or exceeded the high
temperature alarm set point.
To set the high temperature alarm set point:
1. Press the Mode key until the Set High Alarm indicator lights.
2. Press the up or down arrow key until the desired high temperature
alarm set point is displayed.
3. Press Enter to save the setting.
4. Press the Mode key until the Run indicator lights for Run mode
If no control keys are pressed, the freezer will automatically return to RUN
mode after 5 minutes.
Note The high alarm set point must be set at least 5°C from the control
set point. ▲
Note At initial start-up, the high temperature alarm is disabled until the
cabinet reaches set point or 12 hours elapse. ▲
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 Set Low Alarm indicator lights.
2. Press the up or down arrow key until the desired low temperature
alarm set point is displayed.
3. Press Enter to save the setting.
4. Press the Mode key until the Run indicator lights for Run mode
If no control keys are pressed, the freezer will automatically return to RUN

The Run mode is the default mode for the freezer. Run mode displays the
cabinet temperature on the temperature display under normal operating
conditions. In addition, Run mode allows the high stage heat exchange
temperature to be displayed.
This information is scrolled by pressing the up or down arrow keys. The
display will return to the operating temperature in 10 seconds if no keys
are pressed.

Section 2 Calibrate
Once the freezer has stabilized, the control probe may need to be
calibrated. Calibration frequency is dependent on use, ambient conditions
and accuracy required. A good laboratory practice would require at least an
annual calibration check. On new installations, all parameters should be
checked after the stabilization period.
Before making any calibration or adjustments to the unit, it is imperative
that all reference instruments be properly calibrated.
Plug a type T thermocouple reader into the receptacle located inside the
lower door (see Figures 1-4 and 1-6). Compare the control temperature
set point to the temperature of the measuring device.
1. Press the Mode key until the Calibrate indicator lights.
2. Press up/down arrow to match the display to calibrated instrument.
3. Press Enter to store calibration.
4. Press the Mode key to return to Run mode.
Startup - Allow 12 hours for the temperature in the cabinet to stabilize
before proceeding.
Already Operating - Allow at least 2 hours after the display reaches set
point for temperature to stabilize before proceeding.
Note During calibration, the temperature display will not be available. ▲
If no keys are pressed for approximately 5 minutes while in calibration
mode, the system will reset to Run mode.
