Safety precautions
All customers designing and manufacturing a device which uses CKD products have the
responsibility to, and are expected to, manufacture a device that is safe by checking that the safety of
the system operated by the following components is secured: the device mechanism, the gas
combustion equipment circuit, and the electrical control that controls these components
It is important to select, operate, handle, and maintain CKD products appropriately to ensure that
each CKD product is used safely
Please observe all warnings and precautions for each CKD product to ensure the safety of not only
the CKD products but also your device containing CKD products
