Manual Operations And Maintenance 3
Operation mode selection
While two or more indoor units are
simultaneously
operating,
make sure
the modes
do not conflict with
each
other.
The
heat mode
claims precedence over
all other
modes.
If
the
unit intially
started
to
operate
in
HEAT
mode, the
other units
can operate
in
HEAT
mode only. For
example:
If the unit initially
started operates
under
COOL
(or
FAN)
mode, the other units
can
operate
under
any
mode
except HEAT.
If one of the unit
selects HEAT
mode, the other operating units
will
stop operation and
display
”--”
(for units
with
display
window
only)
or the auto and operation
indication light will
flash rapidly,
the defrost
indication light will turn off, and the timer
indication light will
remain
on (for units
without
a
display
window).
Alternatively,
the defrost and
alarm
indication light (if
applicable)
wil light up,
or the operation indication light will
flash
rapidly,
and the timer indication light will turn off
(
for
the floor and
standing
type).

leave
the unit idle for a long time,
perform the following tasks:
1.

the indoor unit and air filter.
2.
Select FAN ONLY
mode and let the indoor fan
run for a time to dry the
inside
of the unit.
3.

supply
and

dispersed
from
the indoor unit.
