1 Introduction
This manual describes installation, use and maintenance of the Snowbird personal ultra freezer.
The Snowbird is a –80 °C freezer primarily designed for direct installation in laboratories, research
departments etc. where easy and quick freezing facilities are required several times a day.
The design allows for installation under standard work tables or laboratory benches.
For additional safety and supervision the freezer may be equipped with CO2backup cooling, extra
temperature sensor and remote alarm via CTS.
2 Safety precautions
Warning
DO NOT touch the internal surfaces of the freezer, frozen products or their packing
with unprotected hands.
Unprotected skin is subject to serious frost injuries.
Wear cryo protective gloves when working in the freezer.
3 Installation

Note
The operating temperature of the freezer compartment is pre-set to –80 °C at the
factory, which is the optimum operating temperature with regards to the
environmental conditions (sound level, power consumption etc). To change this
temperature to e.g. –87 °C follow the instructions in section 7.
The specifications stated in section 10 are obtained at an operating temperature of –80 °C.
Do not install the freezer were it could be exposed to dust or particulate contamination.
The noise level is stated as maximum 45 dB(A). This is valid only during operation of the
compressor, which is approximately 33 % of the time otherwise the freezer is completely silent
during normal operation.
The freezer may be installed as a stand-alone unit or positioned under a work table or laboratory
bench. In both cases the following conditions must be observed:
1 Maximum room temperature of 32 °C.
2 Minimum distance to walls etc. 100 mm.
Position the freezer to avoid direct exposure to sunlight and other sources of heat.
The adjustable feet compensates for any uneven flooring.


Note
The backup battery will only slowly discharge if the main power is disconnected.
Therefore it is recommended that the battery is removed if the freezer is not
operational for long periods.
In order to avoid switching off the freezer unintentionally we recommend to not install a switch
between the mains supply and the freezer.
Connecting the freezer to its own fuse group (minimum ampere) will reduce the risk of power
failure (other instruments cannot then contribute to fuse failure).
Start-up the freezer5.2
When switched ON the 2 Compressors will start, there is a delay between 1st and 2nd Stage
compressors starting.
The display will indicate the actual temperature.
Cooling commences5.3
Ensure that the door is closed!! It will take approximately 2.5 hours to lower the temperature of the
freezer to the pre-set operating temperature.
During the entire cooling down period the actual freezer temperature is shown in the display.
6 Operation
The control system of the Snowbird automatically keeps the temperature of the freezer within a
narrow tolerance range, and if interruptions occurs both acoustic and visual alarms will be
triggered.
Apart from necessary maintenance, the basic instructions for daily use can therefore be confined to
the following statement:
Close the door properly and make sure the freezer is connected to the power supply.

Note
Open doors and power failures are the most frequent causes of "alarm" actuation!

Service mode
To provide restricted access to the system, the programming menu can be password protected.
In order to make changes perform the following procedure step by step.
Press Enter the display “flashes” and shows the code and actual set value.
If you wish to change the value press Up or Down arrow until you have the new value, press Enter
Example: Change of the set point:
1. Press Enter.
2. Press Up or Down till code 1 is displayed.
3. Press Down until –87 is displayed.
4. Press “Enter” to store the new value.
8 Maintenance
Dust filter:
Vacuum cleaning in very dusty rooms once a week under normal conditions at least once a month.
Freezer:
Defrosting as required.
The freezer does not require much maintenance, it is very important however to ensure the
refrigeration capacity of the freezer is maintained by cleaning the radiator grill frequently.
Door sealing:
Wipe and clean the door seals and surfaces of ice crystals as often as possible.
Wipe off condensation and ice crystals on the sealing surface and the free internal surfaces when
the door is open. This will extend the time frequency of conventional defrosting of the freezer.
Battery:
The battery must be replaced once a year. This to be carried out by an authorised service
technician.
CO2:
If the freezer is equipped with CO2back up regularly check the content of CO2 , weighing the flask
or cylinder. Carry out a function test.
How to clean the radiator:

Remove the top front panel. This panel is positioned on the freezer housing with guide pins at
either side, with locating holes on the main body of the cabinet.
Stand in front of the freezer facing it.
Take a firm grip of both sides of the front plate and pull it forwards (towards you) using minimum
force.
As soon as the locating pins are released from the holes, the panel will free of the main cabinet
Avoid drawing the panel too far from the freezer as there is a ribbon cable which connects the
controller to the freezer refrigeration system.
Vacuum-clean the radiator then carefully install the front panel, guide the two locating pins into the
holes and then press back into place.
How to defrost the freezer:
Remove contents from the freezer, switch off the power, allow all the ice to melt, wipe dry, and
switch on the power again.
How to check CO2 weight:
Weigh the CO2flask and compare it with the Tare weight of the flask. A full 180 l flask contains
approx. 22 kg of CO2. One hour’s use is 1-3 kg of CO2 when regulated at -70 C depending on
cabinet volume and type.
Carry out a function test by pressing the test button positioned on the front-side of the battery
charger and observe that CO2is injected into the freezer.
9 Trouble shooting
ALARM is activated - action:
The freezer gives an alarm: A “beep” sounds, and the display shows the alarm code.
Press the alarm signal stops. The red LED will flash, if a new alarm starts the acoustic will
start again.
The display will flash until the fault has been eliminated and the temperature is within limits.
Error Codes:
E6: Power failure.
E5: Pressure switch 1 is OFF.
E4: Pressure Switch 2 is OFF.
E3: Door has been open too long time.
E2: Too high temperature in the freezer.
E1: Too low temperature in the freezer.
