NOTE:
•
Use
the sleep mode when you
are
going
to
bed.lf
this
mode is used
in
the day,the capacity is reduced since the
ambient
temperature
is
too
high.(COOL MODE).
•
During the operation
of
cooling,the room temperature will
be
raised gradually by 2'C(4
'F)
higher than the setting
after
the
machine begins to operate in the sleeping mode.
•
During
the operation of heating mode,the room temRerature
will
be dropped gradually 5'C(9'F) lower than the
setting after the
machine
begins to operate in
the
sleeping mode.
e
REPLACEMENT OF BATTERIES
•
When the signal from
the remote
controller becomes
weak
and the
indoor
unit can not receive it
properly;or
the indications
on
the
display
screen becomes blurred,please
slide
the back cover and replace with
two
new
batteries.
•
The positive and negative poles
must
match the installation positions.
•
New
batteries
of the
same
type
have
to be
used for replacement.
•
If
the
remote controller
is
not to
be
used
for
long
time,
take
out
the
batteries
so
as to prevent
the leakage
of
the
electrolyte
from damaging
the
controller.

Basic principles and performances
0
The machines absorb heat from
the
outdoor air and transfer it
indoors
so as to heat the
room air.
The heating
capabilities
through this principle
of
heat
pump
go up/down
with
the
increase/decrease of the temperatures
of
the outdoor
air.
0
It
only needs a
fairly
short time
for
such
hot
air circulation system
to
raise
the
room temperature.
0
When the outdoor air temperature is very
low,
the system
can
be
used together with other heating devices.
But good ventilation should
be
maintained
to
ensure safety and prevent
accidents.
e
Defrosting
When
the
outdoor
air temperature
is
very low and humidity is very high, frosting
will
occur to the heat exchanger of
the
outdoor
unit,
which
has
negative
impacts upon the efficiency of the heating
performance.
In such
case,
the
automatic
defrosting
function will
come into
play.
The
heating operation will be stopped
for
5-10
minutes to
do
the
defrosting.
0
The fans of both
the
outdoor
and
indoor
units
are stopped.
0
During the
defrosting,
the
outdoor
unit
might
generate
some
steam. It is
caused
by fast
defrosting,
which
is
not a performance
failure.
0
Upon
the
completion
of the defrosting process,
the
heating
operation is
resumed.

OPERATION TIPS
1.Set a suitable room temperature ;excessively
low
room
temperature is not good for your health and
wastes
e lectricity. Avoid frequent setting of the temperature
.
2.During cooling ,avoid direct sun.Keep curtains and blinds
c losed
,
Close doors and windows to keep the cool air in
the
room
.
3.Avoid generating heat or using of heating appliances
while the air conditioner
in cooling
mode
.
4.Make sure that the air flap is positioned properly :
horizontal flow in coo ling and downward vertical f low
for
heating.
5.Keep the room temperature uniform by adjusting the
left/right
vertical
air blades.
6. Position the air
flap
and the left/right air blades in such
a manner as to prevent your body from being exposed
directly to air drafts.
7 .During prolonged operation, ventilate the room
occasionally by opening a window
from time
to t ime.
8. In
a power fai lure, the
microprocessor memory
is reta
ined
.When
restarted,
operation
will
be
resumed
in
the
last
mode of operation.
However,
if the timer was used ,the
unit
will be
turned
off by the timer on
ly
if the remote
co
ntrol is aimed at
the
unit.Otherwise
the
power failure
will cause
the timer data to be erased from the
microprocessor
memory.
9.After turn ing on,allow more
than
3 minu tes for cooling
,
heating or dry operation to start
10.When
DRY mode
is
used,make sure that the room
temperature is between
20.
C/68 .Fand 2TC/81
·F.When
used out of this range
,
the unit may protect itself and
become inoperative.
