AIR INTAKE PORT

When a door is closed and opened soon, a door does not
sometimes open this product.
The warm air which went into the chamber is cooled down rapidly,
and this is because air inside the chamber contracted.
When a door is closed and opened soon, a door is easy to open
with the following process.
1. Turn the cap of the left side counterclockwise about two laps.
(That can be removed completely)
2. Put the air into the chamber from about twenty seconds, and
open a door.
3. Close a cap if a door opens.
A door may not open in the above method when there are frost and ice in the air intake port. In that case,
open a cap, and investigate the matter whether there is no frost inside the air intake port. Remove frost
inside the air intake port in "the air intake port cleaning stick" of the accessories when there is frost.
Clean a air intake port every month even when there is no frost inside the air intake port. Refer to page
24.
WARNING
For removing the frost of the air intake port, do not use a tool with sharp edge such as a knife or a screw
driver.
Replace the cap when the air intake port is not used. Improper replacement may cause rise of chamber
temperature or condensation around the air intake port.
