Important Installer and
User Information:
A redundant temperature sensing device has been included in this
ULT freezer. This device is a type“T”thermocouple.
For convenient access, the thermocouple terminates in an
interconnect jack (Figure 1-4) behind the base front cover.
It is strongly recommended that this thermocouple be attached
to a redundant 24 hour 7 day monitoring system with alarm
capabilities. Connecting the sensor to a monitoring and alarm
system separate from the freezer provides the utmost in product
safety, should the integral system fail.

To remove the freezer from the pallet, use a 7/16”wrench to remove
all the bolts securing the shipping bracket to the pallet.
Note: If tipped more than 45°, allow the unit to set upright for 24
hours before start up.
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 o the pallet.
The freezer can be easily pushed to the desired approved location,
as described previously. When the freezer is in position, set the front
caster brakes.
Note: Do not move the freezer with the product load inside.
CHOOSE LOCATION
Locate the freezer on a rm, 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 airow, 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”.

REMOTE ALARM CONTACTS AND
ANALOG OUTPUT
Cardinal Health™ Ultra-Low freezers have remote alarm contacts
and analog output.
See Figure 1-2 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.
They will also trip on high stage, control probe and microboard
failures. Figure 1-7shows the remote contacts in alarm state.
FIGURE 1-7. Remote Alarm Contacts
IMPORTANT USER INFORMATION
CAUTION! Stored product should be protected by a redundant 24
hour/day monitoring system with alarm capability.
An interconnect jack and thermocouple are installed for centralized
monitoring, should on-board system fail.
The analog output function allows the freezer to output signals
representing the temperature of the freezer cabinet.
The factory default setting is 4-20 mA. Refer to Table 1-2 for
output specications.

CALIBRATE MODE
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.
Note: Before making any calibration or adjustments to the unit,
it is imperative that all reference instruments be properly calibrated.
CALIBRATE CONTROL PROBE
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. See Chart 2-1 for more detail.
1. Press the Mode key until the Calibrate indicator lights.
2. Press the right arrow until“CONT T = -XX.X”appears in the
message center.
3. Press up/down arrow to match the display to
calibrated instrument.
4. Press Enter to store calibration.
5. Press the Mode key to return to Run or the right/left arrow to go
to next/previous parameter.
TEMPERATURE STABILIZATION PERIODS
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 ve minutes while in
calibration mode, the system will reset to Run mode.

HIGH STAGE SYSTEM FAILURE ALARM
This condition is created when the high stage compressor and fans
run for 30 minutes and are not capable of cooling the interstage
heat exchanger to the proper temperature. Under this condition,
the high stage compressor and fans will turn o after 30 minutes
and an audible and visual alarm will occur along with the“HS SYST
FAIL”message in the LED message center.
MULTIPLE ALARMS
When multiple alarm conditions occur, active messages are
displayed in the message center one at a time, updating at 5
second intervals. Pressing Silence during multiple alarms causes all
active alarms to be silenced and to ring back in 15 minutes.
MICRO BOARD FAILURE ALARM
An internal communication failure has occurred with the micro
board. During this alarm, the compressor(s) attempt to run
continuously. However, with this type of failure, freezer operation
becomes undependable.
LOST COMMUNICATION
Communication between the micro board and the display
board has been lost. Under this condition, the visual alarm ashes
along with dashes in the temperature display (----).
