They both contain important informa-tion regarding safety. Be sure to observe all precautions without fail.•Meaning of WARNING and CAUTION noticesWARNING....Failure to follow these instructions properly may result in personal injury or loss of life.CAUTION.....Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances.•The safety marks shown in this manual have the following meanings:Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt.•After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual.WARNING•Ask your dealer or qualified personnel to carry out installation work.Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire.•Install the air conditioner in accordance with the instructions in this installation manual.Improper installation may result in water leakage, electric shocks or fire.•Be sure to use only the specified accessories and parts for installation work.Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.•Install the air conditioner on a foundation strong enough to withstand the weight of the unit.A foundation of insufficient strength may result in the equipment falling and causing injury.•Electrical work must be performed in accordance with relevant local and national regulations and with instructions in this installation manual. Be sure to use a dedicated power supply circuit only.Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire.•Use a cable of suitable length.Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire.•Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal con-nections or wires.Improper connections or securing of wires may result in abnormal heat build-up or fire.•When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires so that the control box lid can be securely fastened.Improper positioning of the control box lid may result in electric shocks, fire or over heating terminals.•If refrigerant gas leaks during installation, ventilate the area immediately.Toxic gas may be produced if the refrigerant comes into contact with fire.•After completing installation, check for refrigerant gas leakage. Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.•When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specified refrigerant (R410A).The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.•During installation, attach the refrigerant piping securely before running the compressor.If the compressor is not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.•During pump-down, stop the compressor before removing the refrigerant piping.If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.•Be sure to earth the air conditioner. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead.Imperfect earthing may result in electric shocks.•Be sure to install an earth leakage breaker.Failure to install an earth leakage breaker may result in electric shocks or fire.CAUTION•Do not install the air conditioner at any place where there is a danger of flammable gas leakage.In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.•While following the instructions in this installation manual, install drain piping to ensure proper drainage and insu-late piping to prevent condensation.Improper drain piping may result in indoor water leakage and property damage.•Tighten the flare nut according to the specified method such as with a torque wrench.If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.AccessoriesChoosing an Installation Site•Before choosing the installation site, obtain user approval.1.Indoor unit.•The indoor unit should be sited in a place where:1)the restrictions on installation specified in the indoor unit installation drawings are met,2)both air intake and exhaust have clear paths met,3)the unit is not in the path of direct sunlight,4)the unit is away from the source of heat or steam,5)there is no source of machine oil vapour (this may shorten indoor unit life),6)cool (warm) air is circulated throughout the room,7)the unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as they may shorten the remote controller range,8)the unit is at least 1 metre away from any television or radio set (unit may cause interference with the picture or sound),9)install at the recommended height (1.8m).2.Wireless remote controller.1)Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly received by the indoor unit (within 7 metres).2)Make the dipswitch settings.

◆采用新型环保冷媒R410A，ODP( 臭氧破坏指数) 为零，不会破坏臭氧层，有利于防止全球气候变暖。
◆所有零部件均符合RoHS 指令，更具环保性。
注：RoHS 指令的全称为《电子电气产品中限制使用某种有害物质》，2003 年2 月13 日由欧盟议会正式公布，2006 年7 月1 日起，投放欧盟市场的新的电子电气设备（豁免条款除外）中不允使用铅、汞、镉、六价铬、多溴联苯（PBB）和多溴二苯醚（PBDE）。
◆在制冷制热均能保持较高的能效比。
年平均COP 值3.5。
◆缩短制冷剂管径。
例如：24HP 机型，气管/ 液管仅为Φ28.6/Φ15.9，而R22 相同机型气管/ 液管为Φ41.3/Φ19.05。
方便配管工作，节省安装空间，节省管材材料费用。
◆智能除霜，更高效制热。
系统高压控制化霜，实现无霜不化。
用高压压力控制化霜的优点是：可以做到“无霜不化”，当在一定工况下，室外空气相对湿度小，基本不结霜，此时机组运行制热效果不受结霜的影响，机组可长时间运行不化霜。
比传统的定时化霜模式节能。
可以延长化霜时间，霜结到一定程度才化，而不是过早化霜或过晚化霜，通过高压值可客观地检测影响室内制热效果的程度。
◆制热范围低至-20℃。
◆长配管设计◆ 5 向接线和配管连接长配管设计冷媒管连接方向二、产品性能与规格1 、产品外形图GMV-R260W2/Na-N2 GMV-R450W3/Na-N1 GMV-R300W2/Na-N2GMV-R560W4/Na-N1 GMV-R860W6/Na-N1GMV-R600W4/Na-N1 GMV-R900W6/Na-N1 2、产品性能参数注：① . 本机组设计执行标准GB/T 18837-2002。
空调R410A制冷剂的工作压力是多少
R410a制冷剂的空调机在制冷模式开机时的低压侧压力表读数是0.6～0.8MPa，高压侧压力表读数是2.2～2.6MPa，在停bai机不运行的状态下，压力表读数0.8～1.1MPa。
R410A新型制冷剂由du两种准共沸混合物组成，主要由氢，氟和碳元素组成，具有稳定、无毒、性能优越的特点。
同时，它不会在没有氯的情况下引起臭氧zhi反应，即不会破坏臭氧层。
扩展资料：
R-410A用途：
R-410A是当今广泛使用的中低温制冷剂，主要用于家用dao空调，中小型商用空调（中小型单元空调，家用中央空调，多联机），移动空调，除湿机，冷冻干燥机，船舶制冷设备，工业制冷及其他制冷设备。
由于R-410A和R22的压力不同，压回缩机使用的油也不同，为了对最初安装R22制冷剂的制冷设备进行售后维护，如有必要，再次添加或更换制答冷剂时，只能添加R22。
通常情况下，不能直接使用R410A代替R22，并且可以通过更换压缩机来替换R410A制冷剂。
