ERQ100~140A7V1BInverter condensing unit4PW51321-1Installation manual2■ Make certain that all electrical work is carried out by qualifiedpersonnel according to the local laws and regulations and thisinstallation manual, using a separate circuit.Insufficient capacity of the power supply circuit or improperelectrical construction may lead to electric shocks or fire.■ Make sure that all wiring is secure, using the specified wires andensuring that external forces do not act on the terminalconnections or wires.Incomplete connection or fixing may cause a fire.■ When wiring between the air handling units and control box, andwiring the power supply, form the wires so that the frontsidepanel can be securely fastened.If the frontside panel is not in place, overheat of the terminals,electric shocks or a fire may be caused.■ If refrigerant gas leaks during installation work, ventilate thearea immediately.Toxic gas may be produced if refrigerant gas comes into contactwith fire.■ After completing the installation work, check to make sure thatthere is no leakage of refrigerant gas.Toxic gas may be produced if refrigerant gas leaks into the roomand comes into contact with a source of fire, such as a fanheater, stove or cooker.■ Before touching electric terminal parts, turn off power switch.Caution■ Ground the air conditioner.Grounding resistance should be according to nationalregulationsDo not connect the earth wire to gas or water pipes,lightning conductor or telephone earth wire.Incomplete grounding may cause electric shocks.■ Gas pipe.Ignition or explosion may occur if the gas leaks.■ Water pipe.Hard vinyl tubes are not effective grounds.■ Lightning conductor or telephone ground wire.Electric potential may rise abnormally if struck by a lightningbolt.■ Be sure to install an earth leakage breaker.Failure to install an earth leakage breaker may cause electricshocks or fire.■ Install drain piping according to this installation manual toensure good drainage, and insulate the pipe to preventcondensation.Improper drain piping may cause water leakage, and make thefurniture get wet.■ Install the air handling and outdoor units, power wire andconnecting wire at least 1 meter away from televisions or radiosto prevent image interference or noise.(Depending on the radio waves, a distance of 1 meter may notbe sufficient to eliminate the noise.)■ Do not rinse the outdoor unit.This may cause electric shocks or fire.■ Do not install the air conditioner in places such as the following:■ Where there is mist of mineral oil, oil spray or vapour forexample a kitchen.Plastic parts may deteriorate, and cause them to fall out orwater to leak.■ Where corrosive gas, such as sulfurous acid gas, isproduced.Corrosion of copper pipes or soldered parts may cause therefrigerant to leak.■ Where there is machinery which emits electromagneticwaves.Electromagnetic waves may disturb the control system, andcause malfunction of the equipment.■ Where flammable gases may leak, where carbon fiber orignitable dust is suspended in the air or where volatileflammables, such as thinner or gasoline, are handled.Such gases may cause a fire.■ Where the air contains high levels of salt such as that nearthe ocean.■ Where voltage fluctuates a lot, such as that in factories.■ In vehicles or vessels.■ Where acidic or alkaline vapour is present.■ Do not touch any refrigerant which has leaked out of refrigerantpiping connections.This may result in frostbite.■ Do NOT connect the system to DIII-net devices:This could result in malfunction or breakdown of the totalsystem.2. INTRODUCTION2.1. CombinationThe air handling units can be installed in the following range.■ Always use appropriate air handling units compatible withR410A.To learn which models of air handling units are compatible withR410A, refer to the product catalogs.■ The manufacturer of this outdoor unit has limited responsibilityfor total capacity of the system because performance isdetermined by the total system. The discharge air may fluctuatedepending on selected air handling unit and depending on theinstallation configuration.■ Both air handling unit and digital controller software andhardware are field supply and are to be selected by the installer.Refer to the manual "Option kit for combination of Daikincondensing units with field supplied evaporators" for moredetails.Recommended temperature setting on the field suppliedcontroller is between 16°C and 25°C.
