1-4! WARNING ! CAUTIONOnly qualified personnel must carry out the installationwork. Installation must be done in accordance with thisinstallation manual. Improper installation may result in waterleakage, electric shock, or fire.When installing the unit in a small room, take measures tokeep the refrigerant concentration from exceeding allowablesafety limits. Excessive refrigerant leaks, in the event ofan accident in a closed ambient space, can lead to oxygendeficiency.Use only specified accessories and parts for installationwork. Failure to use specified parts may result in waterleakage, electric shock, fire, or the unit falling.Install the air conditioner or heat pump on a foundationstrong enough to withstand the weight of the unit. Afoundation of insufficient strength may result in the unitfalling and causing injuries.Take into account strong winds, typhoons, or earthquakeswhen installing. Improper installation may result in the unitfalling and causing accidents.Make sure that a separate power supply circuit is provided forthis unit and that all electrical work is carried out by qualifiedpersonnel according to local, state, and national regulations.An insufficient power supply capacity or improper electricalconstruction may lead to electric shock or fire.Make sure that all wiring is secured, that specified wiresare used, and that no external forces act on the terminalconnections or wires. Improper connections or installationmay result in fire.When wiring, position the wires so that the electrical wiringbox cover can be securely fastened. Improper positioning ofthe electrical wiring box cover may result in electric shock,fire, or the terminals overheating.Before touching electrical parts, turn off the unit.It is recommended to install a ground fault circuit interrupterif one is not already available. This helps prevent electricshock or fire.Securely fasten the outdoor unit terminal cover (panel). If theterminal cover/panel is not installed properly, dust or watermay enter the outdoor unit causing fire or electric shock.When installing or relocating the system, keep the refrigerantcircuit free from substances other than the specifiedrefrigerant (R410A) such as air. Any presence of air or otherforeign substance in the refrigerant circuit can cause anabnormal pressure rise or rupture, resulting in injury.Do not change the setting of the protection devices. If thepressure switch, thermal switch, or other protection deviceis shorted and operated forcibly, or parts other than thosespecified by Daikin are used, fire or explosion may occur.•••••••••••••Do not touch the switch with wet fingers. Touching a switchwith wet fingers can cause electric shock.Do not allow children to play on or around the unit toprevent injury.The heat exchanger fins are sharp enough to cut. To avoidinjury wear gloves or cover the fins while working aroundthem.Do not touch the refrigerant pipes during and immediatelyafter operation as the refrigerant pipes may be hot or cold,depending on the condition of the refrigerant flowing throughthe refrigerant piping, compressor, and other refrigerantcycle parts. Your hands may suffer burns or frostbite if youtouch the refrigerant pipes. To avoid injury, give the pipestime to return to normal temperature or, if you must touchthem, be sure to wear proper gloves.Install drain piping to proper drainage. Improper drain pipingmay 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 stoppingoperation. Always wait for at least 5 minutes before turningoff the power. Otherwise, water leakage may occur.Do not use a charging cylinder. Using a charging cylindermay cause the refrigerant to deteriorate.Refrigerant R410A in the system must be kept clean, dry,and tight.(a) Clean and Dry -- Foreign materials (including mineraloils such as SUNISO oil or moisture) should beprevented from getting into the system(b) Tight -- R410A does not contain any chlorine, does notdestroy the ozone layer, and does not reduce the earth’sprotection again harmful ultraviolet radiation. R410Acan contribute to the greenhouse effect if it is released.Therefore, take proper measures to check for thetightness of the refrigerant piping installation. Read thechapter Refrigerant Piping and follow the procedures.Since R410A is a blend, the required additional refrigerantmust be charged in its liquid state. If the refrigerant is chargedin a state of gas, its composition can change and the systemwill not work properly.The indoor unit is for R410A. See the catalog for indoormodels that can be connected. Normal operation is notpossible when connected to other units.••••••••••••SAFETY PRECAUTIONSINSTALLATION MANUALThis manual provides the procedures of installation to ensure a safe and good standard of operation for the air conditioner unit.Special adjustment may be necessary to suit local requirement.Before using your air conditioner, please read this instruction manual carefully and keep it for future reference.This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial use by laypersons.This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental capabilities, or lack ofexperience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsiblefor their safety.Children should be supervised to ensure that they do not play with the appliance.
