ure (leaky valve) ture that appears on the operation monitor on the outdoor unit's multi control board
while operating the indoor unit in question in the FAN mode and the other indoor
units in the cooling mode.
Normally, the LEV is fully closed while the unit is in the FAN mode. If the valve is

lower than the ambient temperature, valve closure failure is suspected. If the
amount of leakage is insignificant, replacement of LEV is unnecessary unless it is
causing a problem.
