DANGER
•Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
•Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death.
•If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic gas if it comes in contact with Þre. Exposure to this gas could cause severe injury or death.
•After completing the installation work, check that the refrigerant gas does not leak throughout the system.
•Do not install unit in an area where ßammable materials are present due to risk of explosions that can cause serious injury or death.
•Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death by suffocation.
WARNING
•Only qualiÞed personnel must carry out the installation work. Installation must be done in accordance with this installation manual. Improper installation may result in water leakage, electric shock, or Þre.
•When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient space, can lead to oxygen deÞciency.
•Use only speciÞed accessories and parts for installation work. Failure to use speciÞed parts may result in water leakage, electric shocks, Þre, or the unit falling.
•Install the air conditioner on a foundation strong enough that it can withstand the weight of the unit. A foundation of insufÞcient strength may result in the unit falling and causing injuries.
•Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result in the unit falling and causing accidents.
•Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualiÞed personnel according to local, state, and national regulations. An insufÞcient power supply capacity or improper electrical construction may lead to electric shocks or Þre.
•Make sure that all wiring is secured, that speciÞed wires are used, and that no external forces act on the terminal connections or wires. Improper connections or installation may result in Þre.
1 |
English |
•When wiring, position the wires so that the control box cover can be securely fastened. Improper positioning of the control box cover may result in electric shocks, Þre, or the terminals overheating.
•Before touching electrical parts, turn off the unit.
•Be sure to install a ground fault circuit interrupter if one is not already available. This helps prevent electrical shocks or Þre.
•Securely fasten the outdoor unit terminal cover (panel). If the terminal cover/panel is not installed properly, dust or water may enter the outdoor unit causing Þre or electric shock.
•When installing or relocating the system, keep the refrigerant circuit free from substances other than the speciÞed refrigerant (R410A) such as air. Any presence of air or other foreign substance in the refrigerant circuit can cause an abnormal pressure rise or rupture, resulting in injury.
•Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those speciÞed by Daikin are used, Þre or explosion may occur.
CAUTION
•Do not touch the switch with wet Þngers. Touching a switch with wet Þngers can cause electric shock.
•Do not allow children to play on or around the unit to prevent injury.
•Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant ßowing through the refrigerant piping, compressor, and other refrigerant cycle parts.Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.
•Heat exchanger Þns are sharp enough to cut.
To avoid injury wear glove or cover the Þns when working around them.
•Install drain piping to proper drainage. Improper drain piping may result in water leakage and property damage.
•Insulate piping to prevent condensation.
•Be careful when transporting the product.
•Do not turn off the power immediately after stopping operation. Always wait for at least 5 minutes before turning off the power. Otherwise, water leakage may occur.
•Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate.
•Refrigerant R410A in the system must be kept clean, dry, and tight.
(a)Clean and Dry -- Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from getting into the system.
(b)Tight -- R410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce the earthÕs protection again harmful ultraviolet radiation. R410A can contribute to the greenhouse effect if it is released. Therefore take proper measures to check for the tightness of the refrigerant piping installation. Read the chapter Refrigerant Piping Work and follow the procedures.
•Since R410A is a blend, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in a state of gas, its composition can change and the system will not work properly.
•The indoor unit is for R410A. See the catalog for indoor models that can be connected. Normal operation is not possible when connected to other units.
•Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic ßuorescent lamps (inverter or rapid start types). Install the indoor unit far away from ßuorescent lamps as much as possible.
•Indoor units are for indoor installation only. Outdoor units can be installed either outdoors or indoors.
•Do not install the air conditioner in the following locations:
(a)Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in water leakage.
(b)Where corrosive gas, such as sulfurous acid gas, is produced.
Corroding copper pipes or soldered parts may result in refrigerant leakage.
(c)Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and cause the unit to malfunction.
(d)Where ßammable gas may leak, where there is carbon Þber, or ignitable dust suspension in the air, or where volatile ßammables such as thinner or gasoline are handled. Operating the unit in such conditions can cause a Þre.
•Take adequate measures to prevent the outdoor unit from being used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke, or Þre. Instruct the customer to keep the area around the unit clean.
NOTE
•Install the power supply and control wires for the indoor and outdoor units at least 3.5 feet away from televisions or radios to prevent image interference or noise.
Depending on the radio waves, a distance of 3.5 feet may not be sufÞcient to eliminate the noise.
•Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance with the relevant local, state, and national regulations.
•Do not use the following tools that are used with conventional refrigerants: gauge manifold, charge hose, gas leak detector, reverse ßow check valve, refrigerant charge base, vacuum gauge, or refrigerant recovery equipment.
•If the conventional refrigerant and refrigeration oil are mixed in R410A, the refrigerant may deteriorate.

Make sure to use accessories and specified specification parts in the installation work.
4.SELECTION OF INSTALLATION LOCA-
TION
The refrigerant R410A itself is nontoxic, nonßammable and safe. If the refrigerant should leak however, its concentration may exceed the allowable limit depending on room size. Due to this it could be necessary to take measures against leakage. Refer to the chapter ÒCaution for refrigerant leaksÓ.
(1)Select a proper location satisfying the following requirements with approval of the customer.
•Sufficient ventilation is secured.
•Adjacent houses are not annoyed.
•The foundation is strong enough to support the weight and withstand vibrations of the outdoor unit, and the location is safe and allows horizontal installation.
•The outdoor unit is exposed to rain as less as possible.
•The space for installation and servicing is secured around the outdoor unit.
•The indoor/outdoor piping length and wiring length are within the allowable range.
(2)When installing the outdoor unit in a location affected by strong wind, pay special attention to the following items.
•If strong wind whose velocity is 11 mph or more blows to the outdoor unit from the air outlet side, the air flow rate of the outdoor unit is reduced, the outlet air is sucked again (short-circuit), and the following effect may be caused:
•The capacity is deteriorated.
•The adhered frost increases during heating operation.
•The operation is stopped by pressure rise.
•If excessive strong wind continuously blows from the air
outlet side of the outdoor unit, the fan may rotate in the reverse direction at high speed, and lead to damage. Install the outdoor unit in reference to the following figures.
•Position the air outlet side toward the building wall, fence or windbreak screen.
Suction grille
(Secure the space for installation and servicing.)
•Let the air outlet direction face be at right angles to the wind direction.
