Inst uctions elating to heating a e applicable only to "HEAT & COOL TYPE"
Heating Pe fo mance
Mic ocompute -cont olled Automatic Def osting
This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors
As a result, the operating performance is reduced as outdoor air temperature drops If you feel that insufficient heating
perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating
appliance
Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time
may be required after first starting the air conditioner until the room is heated
When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the
outdoor unit, resulting in reduced operating performance
In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic
Defrosting function If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly
(for about 7 to 15 minutes)
Clean the ai filte
Pull the filters upward to remove them from the Intake Grill
Clean the air filter: Remove the dust from the filters by vacuum cleaner or washing
them After washing, allow the air filters to dry thoroughly in an area protected from
sunlight
Re-attach the air filters to the Intake Grill Press the two buttons on the filters until
you hear a sound of click
12
Maintenance
When used for extended periods, the unit may accumulate dirt inside, which reduces its performance We recommend
that the unit is inspected regularly, in addition to your own cleaning and care For more information, consult authorized
service personnel
When cleaning the unit's body, do not use water hotter than 40 C, harsh abrasive cleansers, or volatile agents like
benzene or thinner
Do not expose the unit body to liquid insecticides or hairsprays
When shutting down the unit for one month or more, first allow the Fan mode to operate continuously for about half a
day to allow internal parts to dry thoroughly

Followings a e not p oblems
Sound of water flowing is not a problem
Sound of cracking is heard
Smell are generated
During operation, white fog or steam
comes out from the indoor unit
No outlet air or fan speed can't be changed
in dry mode
In cooling operation, unit switches to
blowing operation
Won't start?
In heating operation, water or steam
are blown out of outdoor unit
In heating operation, indoor fan won't stop
even if unit is stopped
During unit operation or at stop, a swishing or gurgling noise may be heard
This noise is generated by refrigerant flowing in the system
Unit will not restart after stop
During unit operation, a cracking noise may be heard
This noise is generated by the casing expanding or shrinking because of
temperature changes
This is because the system circulates smells from the interior air such as
the smell of cigarettes or the painting on the furniture
When unit is running at places like restaurant, etc where dense edible oil
fumes always exist, this will happen
To prevent frost from accumulating on indoor heat exchanger, unit will switch
to blowing operation for a while then resume cooling operation
Though ON/OFF button is set to ON, the unit won't
resume cooling, dry or heating operation in 3 min
after it is stopped, this is because of
3-min-delay protection circuit
Please wait 3 minutes
Unit will reduce fan speed repeatedly and automatically if room temp is
too low in dry operation
This occurs when frost accumulated on the outdoor unit is removed
(during defrosting operation)
After unit stop, indoor fan will go on running until indoor unit cools down
