Master power switch
The main power switch must be turned on for the system to operate properly.
Temperature display and indicator light
The display screen shows the actual temperature in the storage cabinet;
When the snow flake light is lit on the display, the feed solenoid valve is activated and the
injection is in process.
When the “ ” light is lit on the display, the man power switch is in off mode.
ERR on the display indicates a sensor failure.
,
System battery switch
The system‘s battery switch must be turned on. During a power outage, the battery can
then supply the power to run the backup system.
Standby test key
The test key is to allow a temporary activation of the solenoid valve. This is to ensure the
flow of cryogen is available to the freezer when called by the controller.
Indicator light for ‘Low Carbon Dioxide’
When the indicator is turned on, the pressure in the carbon dioxide tank is lower than 35 bar.
The tank must be replaced to ensure a proper cooling is available from the backup system.
Indicator light for ‘Low Battery’
When the indicator is turned on, the battery power is low and it needs to be charged.
Connect the AC power to a power outlet to charge the system.
Indicator light for ‘Battery Charging’
When the indicator light is on, it indicates the battery is being charged;

Temperature adjustment
1Initial status of power on
When installation of a backup system is completed, plug in the power cord to a power supply.
Turn on the main power switch and the battery charge switch. The backup system is in the
standby state. All control parameters are the same as from the last power down. The display
shows the current freezer temperature. The default factory setting for the temperature
control is -70 .
2. Adjustment for temperature settings and parameters
Three buttons, set, up arrow and down arrow, are used to make an adjustment of the
temperature setting and parameters.
In normal mode:
Press and hold Set for 1 second and more. The flashing display will show the set temperature
value. Press Up or Down arrow to adjust the set point temperature. Press Set again to save
the change. The temperature range is -40 ℃to -99 ℃.
Press and hold Set button for more than 3 seconds to access the parameter menu. Press Set
button again, control parameter Rd appears. Use Up or Down arrow to adjust the value from
1 to 10℃. Press and hold the Set button for 3 seconds to save the new parameter. The Rd
parameter represents the temperature differential that the controller operates the injection
solenoid valve. When the actual freezer temperature warms up backup temperature setting
plus the differential, the controller will activate the injection solenoid valve. Coolant will be
injected to the freezer, attempting to bring the temperature down. When the actual
temperature reaches the set point in the backup system, the injection will stop. The cycle will
repeat until the freezer temperature becomes colder than the set point in the backup system.
3. If a backup system is not used and disconnected off a freezer, make sure to turn off the
main switch and the battery charge switch. Otherwise, the drained battery may not be
chargeable again.

A backup system should be cleaned regularly. For safety, disconnect its power before
cleaning. Use a soft cloth and mild detergent solution for cleaning if necessary. Use a
dry cloth to dry it off after cleaning.
Never use a strong solution such as organic chemicals, boiling water, detergent, acid or
a hardwire brush to clean the equipment. Do not use a water hose to flush the system.
If the system is out of service for a while and it needs to be cleaned, follow the
instruction above.
The equipment should be inspected by qualified personnel on a regular basis. Should
there be any issues, consult with the factory or your representative.
1.Power up the ULT freezer. Let it run to the set freezer temperature.
2.Turn on the main power switch and the battery charge switch on the
backup system.
3.Start the test procedure. Set the backup system’s set point temperature
10 C colder than the actual freezer temperature. The backup system will
start injecting coolant into the freezer. Open the freezer door, the injection
should stop. Close the door, the injection will continue as long as the backup
system’s set temperature is not satisfied. The door switch directly controls
the action of injection solenoid valve for safety reason. A Preventive
Maintenance procedure should always include checking the contact integrity
and the function of the door switch.
4.When the freezer is at stable temperature, set the backup system’s set point
temperature 10℃warmer than the freezer temperature to avoid unnecessary
coolant injection. A user should decide the set point value based on the critical
nature of the stored products. For a CO2 backup system, the system will inject
continuously if the set point is lower than -75℃.
5.If the freezer is turned off, unplug the door switch harness from the back of the
backup system. This will stop any unnecessary coolant injection while the
battery is charged.
6.Keep the backup system connected to a power supply. If the battery runs the
system for a long period of time, the battery may not be rechargeable.
7.The consumption rate of LCO2 and LN2 depends on the size of the freezer
and product load. The average consumption rate is between 2 and 4 kg/hr.

Meaning of crossed out wheeled dustbin:
Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities.
Contact your local government for information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into
the groundwater and get into the food chain, damaging your health and well-being.
When replacing old appliances with new ones, the retailer is legally obligated to take back your
old appliance for disposals at least free of charge.
