1. 3 Set the warning indicator of the temperature i setting knob of the back up system at the temperature higher than 70 C The back up system is operated continuously if the warning indicator is set at the temperature lower than 70 C This means the liquid CO gas is consumed very quickly 4 Switch on the back up system 5 Make sure that liquid CO gas spouts into the freezer chamber by pressing the back up test switch Note The liquid CO gas cylinder loses its cooling capacity at speed when the ambient temperature is over 31 C Install the liquid CO gas cylinder in the cool environment And the duration of back up time per one liquid CO gas cylinder varies depending on the ambient temperature Refer to Installation of back up system enclosed with the freezer for the available back up time The liquid CO gas cylinder should be a siphon type Use the pipe encloses with the freezer for the setting The extension of the pipe is not permitted because of cooling capacity 30 SPECIFICATIONS Name Model External dimensions Internal dimensions Effective capacity Exterior Interior Door Insulation Compressor Motor for compressor High stage side 1100 W Low stage side 1100 W Condenser Evaporator Refrigerant Power source Temperature controller Microprocessor control system Setting range 20 to 95 C 1 C graduation Temperature display Alarm Battery Voltage booster A2. The freezer is in the direct sunlight There is any heating source near the freezer A rubber cap and insulation for the access port are not set correctly You put too many unfrozen articles into the freezer compartment Too much frost is accumulated in the chamber The alarm test key does not function when the power switch of the freezer is OFF a When only the buzzer or only the alarm is actuated by the alarm test key the unactuated part is out of order and must be replaced The freezer is not installed on the sturdy floor There is anything touching the frame The freezer is not leveled with the leveling feet It is the immediately after starting of refrigeration The freezer causes larger noise when the chamber temperature is high because of large load The noise gets smaller along with chamber temperature The cooling is poor Alarm test key cannot actuate the alarm a The liquid CO cylinder is empty The valve of the liquid CO cylinder is not opened a The ambient temperature is too high In this case move the liquid CO cylinder to a cool location Inquire at liquid CO suppliers about cylinder check adjustment installation or move CO back up test switch does not operate normally when the back up system is provided Note If the malfunction is not eliminated after checking the above items or the malfunction
