BACK-UP SYSTEM (OPTION)

With the back-up system (CVK-UB4), the freezer prevents the chamber temperature from going up by injecting the liquid CO2 gas when the power supply is disconnected (power failure, disconnection of power cord, breaker OFF) or in the case of failure of freezer itself. The liquid CO2 gas is injected with the activation of solenoid valve energized by battery when the chamber temperature reaches the alarm temperature.

Following shows the procedure for setting the back-up system.

1.Setting of liquid CO2 gas cylinder

By using the joint and pipe enclosed with the back-up system, connect the liquid CO2 gas cylinder to the joint of the back-up system. For this setting, consult with a qualified gas supplier or Sanyo sales agency.

2.After setting the liquid CO2 gas cylinder, operate the freezer until the chamber temperature reaches the required level.

3.Set the temperature of back-up operation at the temperature higher than -70oC. The back-up system is operated continuously if the temperature of back-up operation is set at the temperature lower than -70oC. This means the liquid CO2 gas is consumed very quickly.

4.Switch on the back-up system.

5.Make sure that liquid CO2 gas spouts into the freezer chamber by pressing the back-up test switch.

Note:

ŶThe liquid CO2 gas cylinder loses its cooling capacity at speed when the ambient temperature is over

31oC. Install the liquid CO2 gas cylinder in the cool environment. And the duration of back-up time per one liquid CO2 gas cylinder varies depending on the ambient temperature. Refer to “Installation of back-up system” enclosed with the back-up system for the available back-up time.

ŶThe liquid CO2 gas cylinder should be a siphon type.

ŶUse the pipe encloses with the back-up system for the setting. (The extension of the pipe is not permitted because of cooling capacity.)
