Disposal of the old air onditioner
Bef re disp sing an ld air c nditi ner that g es ut f use, please make sure it's in perative and safe. Unplug the air c nditi ner
in rder t av id the risk f child entrapment.
It must be n ticed that air c nditi ner system c ntains refrigerants, which require specialized waste disp sal. The valuable
materials c ntained in a air c nditi ner can be recycled. C ntact y ur l cal waste disp sal center f r pr per disp sal f an ld
air c nditi ner and c ntact y ur l cal auth rity r y ur dealer if y u have any questi n. Please ensure that the pipew rk f y ur

D n t damage any parts f the air c nditi ner that carry refrigerant by piercing r perf rating the air c nditi ner's tubes with
sharp r p inted items, crushing r twisting any tubes, r scraping the c atings ff the surfaces. If the refrigerant spurts ut and
gets int eyes, it may result in seri us eye injuries.
D n t bstruct r c ver the ventilati n grille f the air c nditi ner. D n t put fingers r any ther things int the inlet/ utlet and
swing l uver.
D n t all w children t play with the air c nditi ner. In n case sh uld children be all wed t sit n the utd r unit.
This appliance is n t intended f r use by pers ns (including children) with reducedphysical, sens ry r mental capabilities, r

"HOT KEEP" is perated in the f ll wing cases.
When heating is started:
In rder t prevent bl wing ut f c l wind, the ind r unit fan st pped acc rding t the r m temperature which heating
perati n is started. Wait f r appr x. 2 t 3 minute, and the perati n will be aut matically changed t the rdinary heating

Defr sting perati n (in the heating m de):
When it is liable t fr st, the heating perati n is st pped aut matically f r 5 t 12 minutes nce per appr x. ne h ur,
and defr sting is perated. After defr sting is c mpleted, perati n m de is aut matically changed t rdinary heating
perati n.
When the r m therm stat is actuated:
When r m temperature increases and r m temperature c ntr ller actuates, the fan speed is aut matically changed t
st p under l w temperature c nditi n f ind r heat exchanger. When r m temperature decreases, air c nditi ner
aut matically changes ver t rdinary heating perati n.
Heat pump type warming
With the heat pump type warming, the mechanism f heat pump that c ncentrate heat f utd r air with the help f
refrigerant t warm the ind r space, is utilized.
Defr sting perati n
When a r m is warmed with a heat pump type air c nditi ner, fr st accumulates n the heat exchanger f utd r unit
al ng with the dr p f ind r temperature. Since the accumulated fr st reduces the effect f warming, it is necessery t
aut matically switch the perati n t the defr sting m de. During the defr sting perati n, heating perati n is interrupted.
Atm spheric temperature and warming capacity
Warming capacity f heat pump type air c nditi ner decreases al ng with the dr p f utd r temperature.
When the warming capacity is n t sufficient, it is rec mmended t use an ther heating implement.
Peri d f warm-up
Since the heat pump type air c nditi ner empl ys a meth d t circulate warm winds t warm
the entire space f a r m, it takes time bef re the r m temperature rises.
It is rec mmendable t start the perati n a little earlier in a very c ld m rning.

shooting
list
1. For the indoor failure,only running LED ON remote receiver will indicate.
2. For the outdoor failure,timer LED and running LED will indicate.timer LED of remote receiver stands for ten's lace,and running LED stands for one's
lace.timer LED will flash firstly,2 seconds later,running LED will flash too. Afer that,4 seconds later,they will flash in turns again.Flash times equals to the
failure code of outdoor lus.
20.For exam le,failure code of outdoor is 2,the indoor unit should dis lay 22.As a result,timer LED flashes twice firstly,then running LED flashes twice.
3.To get much more details of outdoor unit failure,Please refer to the the outdoor unit trouble shooting list.
