Installation manual2Caution Ground the air conditioner.Grounding resistance should be according to nationalregulations.Do 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 lightning. Be sure to install an earth leakage breaker.Failure to install an earth leakage breaker may cause electricshocks and fire. Install drain piping according to this installation manual to ensuregood drainage, and insulate the pipe to prevent condensation.Improper drain piping may cause water leakage, and make thefurniture get wet. Install the indoor and outdoor units, power wire and connectingwire at least 1 meter away from televisions or radios to preventimage 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 orfire. 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, causing them to fall out orwater to leak. Where corrosive gas, such as sulphurous 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 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.Provide a logbookIn accordance with the relevant national and international codes, itmay be necessary to provide a logbook with the equipmentcontaining at least- info on maintenance,- repair work,- results of tests,- stand-by periodes,- etc...In Europe, EN378 provides the necessary guidance for this logbook.Before installationPrecautions for R410A The refrigerant requires strict cautions for keeping the systemclean, dry and tight.- Clean and dryForeign materials (including mineral oils or moisture) should beprevented from getting mixed into the system.- TightRead "Precautions on refrigerant piping" on page 6 carefully andfollow these procedures correctly. Since R410A is a mixed refrigerant, the required additionalrefrigerant must be charged in its liquid state. (If the refrigerant isin a state of gas, its composition changes and the system will notwork properly). The connected indoor units must be indoor units designedexclusively for R410A.Installation For installation of the indoor unit(s), refer to the indoor unitinstallation manual. Illustrations show class 125 outdoor unit type. Other types alsofollow this installation manual. This outdoor unit requires the pipe branching kit (optional) whenused as the outdoor unit for the simultaneous operation system.Refer to catalogues for details. Never operate the unit with a damaged or disconnecteddischarge thermistor and suction thermistor, burning of thecompressor may result. Be sure to confirm the model name and the serial no. of theouter (front) plates when attaching/detaching the plates to avoidmistakes. When closing the service panels, take care that the tighteningtorque does not exceed 4.1 N•m.AccessoriesCheck if the following accessories are included with the unitSince maximum working pressure is 4.0 MPa or 40 bar,pipes of larger wall thickness may be required.
