Sanyo MDF-C8V service manual Precautions For Safe Operation, with the freezer

PRECAUTIONS FOR SAFE OPERATION

WARNING

Only qualified engineers or service personnel should install this system. The installation by

unqualified personnel may cause electric shock or fire.

Turn off the all switches and disconnect the power supply to the ultra low temperature freezer prior to the attachment of the back-up system in order to prevent electric shock or injury.

Never disassemble, repair, or modify the unit yourself. Any such work carried out by an unauthorized person may result in fire or injury due to a malfunction.

There is a terminal (AC 100V) of the high voltage in the back-up system. Attach the back-up

unit cover before starting the trial operation. The operation without the cover may cause electric shock.

CO2 gas is released when the back-up system is operated. Use this kit in well-ventilated environment as high CO2 density level may cause a deficiency of oxygen.

CAUTION

This manual includes the attachment procedure for CVK-UB4 and CVK-UB4(I) only. For its operation and the operation of a ultra-low temperature freezer, see an instruction manual provided

with the freezer.

Put on the dry gloves to protect the hands at the time of attachment. No gloves may cause cut

of the finger by the edge or corner.

Connect a pipe from a liquid CO2 gas cylinder to this unit correctly. Incorrect connection may cause gas leakage.

Check the gas piping before trial operation to avoid gas leakage.

Stop the operation immediately and review the attachment procedure carefully if there is

something wrong with the back-up system during the trial operation.
