z
If operations are continued for a long time with the air condi-
tioner set to the lowest temperature and minimum air flow,
there is danger that the receiver drier may freeze.
z If it freezes and no cold air comes out, stop using the cool-
ing, and set to a higher temperature and the maximum air
flow. Run for a short time under these conditions, then
return.
