Features
This air conditioner is equipped with cooling, heating and drying functions. Details on these functions are
provided below; refer to these descriptions when using the air conditioner.
•
Microprocessor Controlled Operation
The interior compartment of the remote
control unit contains several features to
facilitate automatic operation, easy logically
displayed for easy use.
•
Simple One-touch Wireless Remote Control
The remote control unit has several features to
facilitate automatic operation.
•
24-Hour ON or OFF Timer
This timer can be set to automatically turn the
unit on or off at any time within a 24 hour
period.
•
1-Hour OFF Timer
This timer can be set to automatically turn off
the unit at any time after one hour.
•
Night Setback
Pressing this button changes the setting of the
room temperature thermostat, allowing you to
set the temperature at whatever level that you
find comfortable.
•
Automatic and 3-step Fan Speed
Auto/High/Medium/Low
•
Air Sweep Control
This function moves a flap up and down in the
air outlet, directing air in a sweeping motion
around the room and providing comfort in
every corner.
•
Automatic Switching between Cooling and
Heating
This unit automatically switches between
cooling operation and heating operation
according to the difference between the room
temperature and the temperature setting.
•
Hot Start Heating System
Right from the start, the air is warm and
comfortable. This system prevents any cold
blasts at the beginning while the heat pump is
warming up, or even defrosting.
•
Automatic Restart Function for Power Failure
Even when power failure occurs, preset
programmed operation can be reactivated
once power resumes.
•
Anti-Mold Filter
This unit is equipped with an anti-mold filter
that inhibits the growth of mold and bacteria.
CAUTION
•
Optional Air Clean Filter
An air filter that uses activated charcoal to
eliminate unpleasant odors and clean the air is
available (sold separately).
If the outdoor temperture is extreamly low, it is recommended
to use another heating appliance:
When the outdoor temperature falls to around 5°F, the compressor stops.
However, indoor fan continues to operate even after the compressor has
been stopped. In this case, to prevent room from freezing, use another
heating appliance.

Installation Location
•
We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the Installation
Instructions provided with the unit.
•
Before installation, check that the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
•
Do not install this air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.
•
Do not install the air conditioner where excessively high heatgenerating objects are placed.
Avoid: To protect the air conditioner from heavy corrosion, avoid installing the
outdoor unit where salty sea water can splash directly onto it or in
sulphurous air near a spa.
Electrical Requirements
1. All wiring must conform to the local electrical codes. Consult your
dealer or a qualified electrician for details.
2. Each unit must be properly grounded with a ground (or earth) wire or
through the supply wiring.
3. Wiring must be done by a qualified electrician.
CAUTION
Safety Instructions
•
Read this Instruction Manual carefully before using this air conditioner.
If you still have any difficulties or problems, consult your dealer for
help.
•
This air conditioner is designed to give you comfortable room
conditions. Use this only for its intended purpose as described in this
Instruction Manual.
•
Never use or store gasoline or other flammable vapor or liquid near
the air conditioner – it is very dangerous.
•
This air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you use
gas or oil heating appliances in the same room, which
consume a lot of oxygen from the air. Otherwise there is a risk of
suffocation in an extreme case.
•
Do not turn the air conditioner on and off from the power mains
switch. Use the ON/OFF operation button.
•
Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.
•
Do not let children play with the air conditioner.
•
Do not cool the room too much if babies or invalids are present.

TIMER
•
Once the room temperature reaches the level that was set, the unit
repeats the cycle of turning on and off automatically.
•
During DRY operation, the fan speed is automatically set to LOW or
VERY LOW; the fan speed then switches back and forth between
LOW (for 20 seconds) and VERY LOW (for 10 seconds).
•
“DRY” operation is not possible if the indoor temperature is 59°For
less.
•
Because this air conditioner heats a room by drawing in the heat of
the outside air (heat pump system), the heating efficiency will fall off
when the outdoor temperature is very low. If sufficient heat cannot
be obtained with this air conditioner, use another heating appliance
in conjunction with it.
•
When the outdoor temperature is low, frost or ice may form on the
heat exchanger coil, reducing heating performance. When this
happens, a microcomputer defrosting system operates. At the same
time, the fan on the indoor unit stops and the STANDBY lamp
remains lit until defrosting is completed. Heating operation restarts
after several minutes. (This interval will vary slightly depending
upon the outdoor temperature and the way in which frost forms).
•
For several minutes after the start of heating operation, the indoor
fan will not start running until the indoor heat exchanger coil has
warmed up sufficiently. This is because the COLD DRAFT
PREVENTION SYSTEM is operating. During this period, the
STANDBY lamp remains lit.
•
The STANDBY lamp also remains lit during defrosting or when the
compressor has been turned off by the thermostat when the system
is in the heating mode.
•
Upon completion of defrosting and when the compressor is turned
on again, for heating operation, the STANDBY lamp will go off
automatically.

Adjusting the Airflow Direction
1. Horizontal The horizontal airflow can be adjusted by moving the vertical vanes with your
hands to the left or right.
CAUTION When the humidity is high, the vertical vanes should be in the front
position during the cooling or dehumidifying operation. If the vertical vanes
are positioned all the way to the right or left, condensation may begin
to form around the air vent and drip down.
