• The products which cotrolled by
temperature shall not be stored
in the refrigerator.
Do not store articles on the
product.
• Opening or closing the door
may throw down which may
inflict a wound.
Use the rated components on
the replacement.
• Check the correct model, rated
voltage, rated correct, operating
temperature and so on.
On repair, make sure that the wires
such as harness should be bundled
tightly.
• Bundle tightly wires in order not to
be detached by the external force
and then not to be wet.
On repair, remove completely
dust or other things of housing
parts, harness parts, and check
parts.
• Cleaning may prevent the possible
fire by tracking or short
After repair, check the assembled
state of components.
• It must be in the same assembled
state when compared with the
state before disassembly.
Check if there is any trace indicating
the permeation of water.
• If there is that kind of trace, change
related components or do the
necessary treatment such as taping
using the insulating tape.
