This symbol refers to a hazard or unsafe practice which can result in personal
injury or product or property damage.
If Necessary, Get Help
These instructions are all you need for most installation sites and maintenance conditions. If you
require help for a special problem, contact our sales/service outlet or your certified dealer for
additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or maintenance service,
including failure to follow the instructions in this document.
SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.
● Do not supply power to the unit until all wiring and tubing are completed or reconnected and
checked.
● Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram
and these instructions when wiring. Improper connections and inadequate grounding can cause
accidental injury or death.
● Ground the unit following local electrical codes.
● Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible
fire hazard.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend
your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air
conditioner can cut your fingers.
When Installing
● In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to
construct a strong wood or metal frame to provide added support.
● In a Room
Properly insulate any tubing run inside a room to prevent“sweating” that can cause dripping and
water damage to walls and floors.
● In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit.
This prevents water damage and abnormal vibration.
● In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.
● In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
△ Use the flare method for connecting tubing.
△ Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting
them, then tighten the nut with a torque wrench for a leak free connection.
△ Check carefully for leaks before starting the test run.
When Servicing
△ Turn the power OFF at the main power box (mains) before opening the unit to check or repair
electrical parts and wiring.
△ Keep your fingers and clothing away from any moving parts.
△ Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being serviced.
Others
△ Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped
refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.
△ Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in
contact with a stove, gas water heater, electric room heater or other heat source, it can produce
dangerously toxic gas.
NOTE:

position plus 5º.
4-3-8-4 Outdoor fan
The outdoor fan speeds except single speed motor can be changed according to outdoor ambient
temperatures.
3-7-6 4-way valve
State: It is electrified in heating.
Switchover: When initially powered on for heating, the 4-way valve is activated immediately.
In the change from cooling to heating, it needs an interval of 50 seconds for the 4-way valve to
change over from being interrupted to being activated.
3-8 The super function (option)
In cooling mode, when you press the SUPER button by remote control, the unit will operate for 15
minutes with the following setting:
a. The set temperature is 16℃;
b. The fan speed with highest speed;
c. The compressor runs with high frequency.
3-9 Dehumidifying mode
The dehumidifying mode is illustrated as follows:
Dehumidifying area I: Operation at the frequency in the range (30–60Hz) according to Dt (T
ambient-Tset
).
Dt(℃)
f(Hz)

≥2 60
Dehumidifying area II: The compressor stops for 5 minutes and operators for 5 minutes at the lowest
frequency.
Dehumidifying area III: The compressor stops.
3-10 Fan Only Mode Operation
During the appliance run in this mode, the compressor and outdoor fan stop, the indoor fan
operate under the pre-setting of air volume, and the louver swing, and the indoor fan speed same as
the Heating Mode.
5-3. Special Function Fnstruction
Conditions of anti-freezing prohibition of frequency rising:
Condition 1: in the case of anti-freezing frequency decreasing, the temperature of indoor heat exchanger rises to
“anti-freezing frequency decreasing temperature”.
Condition 2: in normal operation, the temperature of indoor heat exchanger reaches “anti-freezing prohibition of
frequency rising temperature”.
Either of the above two conditions is met, the product will enter anti-freezing prohibition of frequency rising state.
Anti-freezing prohibition of frequency rising operation: the compressor is kept at the current frequency, which may
decrease according to situations while cannot rise. The outdoor fan runs.
Condition for the end of anti-freezing prohibition of frequency rising state: when the temperature of indoor heat
exchanger rises to “anti-freezing releasing temperature”, the state of anti-freezing prohibition of frequency rising
is released.
Conditions for defrosting:
A: When the heating compressor consecutively runs for 40 minutes (EEPROM setting value at the current
operating mode);
B:If the ambient temperature minus the temperature of coiled pipe is equal to or higher than six degrees
centigrade (EEPROM setting value in the current operating mode);
C:If the temperature of coiled pipe is equal to or lower than minus two degrees centigrade (EEPROM setting
value in the current operating mode);
If the above three conditions are met simultaneously, defrosting begins.
Defrosting actions:
The compressor stops, and the outdoor fan stops after delay of 30 seconds; in 50 seconds the four-way
valve is power off; and in 10 seconds the compressor starts and runs at “defrosting frequency”.
Conditions for ending defrosting:
Defrosting is over if either of the below conditions is met.
A：The accumulated time of defrosting is longer than 12 minutes (EEPROM setting value in the current
operating mode);
B：If the temperature of coiled pipe is equal to or higher than 14 degrees centigrade (EEPROM setting value
in the current operating mode);
Actions of exiting the defrosting state:
The compressor stops, and 50 seconds later the four-way valve opens, and another 10 seconds later the
compressor and outdoor fan restart and begin normal operation.
