1. Safety Considerations
IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and operating standards. As the installer or service
person, it is an important part of your job to install or service the system, so it operates safely and
efficiently.
For safe installation and trouble-free operation, you must:
●Carefully read this instruction booklet before beginning.
●Follow each installation or repair step exactly as shown.
●Observe all local, state, and national electrical codes.
●Pay close attention to all warning and caution notices given in this manual.
This symbol refers to a hazard or unsafe practice which can result in severe
personal injury or death.
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

3
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:
The figure 、 size and parameter of the product may not be identical with the service manual, please
take the actual product as the standard.

4. Installation Instruction
To prevent abnormal heat generation and the possibility of fire, do not place
obstacles, enclosures and grilles in front of or surrounding the air conditioner in a
way that may clock air flow. And, more than 1 meter away from any antenna or power lines or connecting
wires used for TV, radio, telephone, security system, or intercom. Electrical noise from any of these
sources may affect operation.
4-1. Installation Place and Condition
Indoor unit
Avoid:
△direct sunlight.
△nearby heat sources that may affect performance of the unit.
△areas where leakage of flammable gas may be expected.
△places where large amounts of oil mist exist.
Do:
△Select an appropriate position from which every corner of the room can be uniformly cooled.

10
△Select a location that will hold the weight of the unit.
△Select a location where tubing and drain hose have the shortest run to the outside. (See a)
△Allow room for operation and maintenance as well as unrestricted air flow around the unit. (See b)
△Install the unit within the maximum elevation difference (H) above or below the outdoor unit and
within a total tubing length (L) from the outdoor unit as detailed (See table 1 and c)

* If total tubing length becomes 7.5 to 15 m (max.), charge additional refrigerant as the table1 for
reference. And no additional compressor oil is necessary.
Outdoor unit
Avoid:
△Heat sources, exhaust fans, etc.
△Damp, humid or uneven locations.
DO:
△Choose a place as cool as possible.
△Choose a place that is well ventilated.
△Allow enough room around the unit for air intake or exhaust and possible maintenance. (see a1,
b1 & c1)
△Provide a solid base (level concrete pad, concrete block, 10 × 40 cm beams or equal), a minimum
of 10 cm above ground level to reduce humidity and protect the unit against possible water damage

11
and decreased service life.
△Install cushion rubber under unit’s feet to reduce vibration and noise.
△Use lug bolts or equal to bolt down unit, reducing vibration and noise.

4-4. Air Purging and Leakage Test
1. Connect charging hose of manifold valve to charge end of low pressure valve (both high/low
pressure valves must be tightly shut).
2. Connect joint of charging hose to vacuum pump.
3. Fully open the handle of Lo manifold valve.
4. Open the vacuum pump to evacuate. At the beginning, slightly loosen joint nut of low pressure
valve to check if there is air coming inside. (If noise of vacuum pump has been changed, the reading
of multimeter is 0) Then tighten the nut.
5. Keep evacuating for more than 15mins and make sure the reading of multi-meter is -1.0 X105 pa
(-76cmHg).
6. Check the vacuum with the gage manifold valve, then close the gage manifold valve, and stop the
vacuum pump.
7. Leave it for one or two minutes. Make sure the pointer of the gage manifold valve remains in the
same position.
8. Remove the gage manifold valve quickly from the service port of the stop valve.
After refrigerant pipes are connected and evacuated, fully open all stop valves on gas and liquid pipe
sides.
9. Opening without fully opening lowers the performance and cause dangerous.
10. Tighten the cap to the service port to obtain the initial status.
11. Retighten the cap

If the unit has I feel function, when the I feel function is set by the remote control, the room
temperature will depend on the remote control and it will be detected by the sensor of the remote
control. Normally the remote control will automatically transmits a signal at an interval of 10
minutes（only for H1 remote control, it is 9 minutes）, but if the room temperature changed exceed
1℃in a short period of time, the remote control will transmits a signal within 2 minutes. If the indoor
unit has not received a remote signal within 30 minutes, the room temperature will depend on the
room temperature sensor of indoor unit.
