5 1 Generl sfety preutions Mke sure refrigernt piping instlltion omplies with pplile legisltion. In Europe, EN378 is the pplile stnr. Mke sure the fiel piping n onnetions re not sujete to stress. WARNING During tests, NEVER pressurize the prout with pressure higher thn the mximum llowle pressure (s inite on the nmeplte of the unit). If A siphon tue is present (i.e., the yliner is mrke with "Liqui filling siphon tthe") A siphon tue is NOT present Then Chrge with the yliner upright. Chrge with the yliner upsie own. WARNING Tke suffiient preutions in se of refrigernt lekge. If refrigernt gs leks, ventilte the re immeitely. Possile risks: Exessive refrigernt onentrtions in lose room n le to oxygen efiieny. Toxi gs my e proue if refrigernt gs omes into ontt with fire. DANGER: RISK OF EXPLOSION Pump own Refrigernt lekge. If you wnt to pump own the system, n there is lekge in the refrigernt iruit: Do NOT use the unit's utomti pump own funtion, with whih you n ollet ll refrigernt from the system into the outoor unit. Possile onsequene: Self-omustion n explosion of the ompressor euse of ir going into the operting ompressor. Use seprte reovery system so tht the unit's ompressor oes NOT hve to operte. WARNING Alwys reover the refrigernt. Do NOT relese them iretly into the environment. Use vuum pump to evute the instlltion. After ll the piping hs een onnete, mke sure there is no gs lek. Use nitrogen to perform gs lek etetion. To voi ompressor rekown, o NOT hrge more thn the speifie mount of refrigernt. When the refrigernt system is to e opene, refrigernt must e trete oring to the pplile legisltion. WARNING Mke sure there is no oxygen in the system. Refrigernt my only e hrge fter performing the lek test n the vuum rying. In se re-hrge is require, refer to the nmeplte of the unit. It sttes the type of refrigernt n neessry mount. The unit is ftory hrge with refrigernt n epening on pipe sizes n pipe lengths some systems require itionl hrging of refrigernt. Only use tools exlusively for the refrigernt type use in the system, this to ensure pressure resistne n prevent foreign mterils from entering into the system. Chrge the liqui refrigernt s follows: Open refrigernt yliners slowly. Chrge the refrigernt in liqui form. Aing it in gs form my prevent norml opertion. CAUTION When the refrigernt hrging proeure is one or when pusing, lose the vlve of the refrigernt tnk immeitely. If the vlve is not lose immeitely, remining pressure might hrge itionl refrigernt. Possile onsequene: Inorret refrigernt mount Brine If pplile. See the instlltion mnul or instller referene guie of your pplition for more informtion.

6 2 Aout the oumenttion Eletril DANGER: RISK OF ELECTROCUTION Turn OFF ll power supply efore removing the swith ox over, onneting eletril wiring or touhing eletril prts. Disonnet the power supply for more thn 1 minute, n mesure the voltge t the terminls of min iruit pitors or eletril omponents efore serviing. The voltge MUST e less thn 50 V DC efore you n touh eletril omponents. For the lotion of the terminls, see the wiring igrm. Do NOT touh eletril omponents with wet hns. Do NOT leve the unit unttene when the servie over is remove. WARNING If NOT ftory instlle, min swith or other mens for isonnetion, hving ontt seprtion in ll poles proviing full isonnetion uner overvoltge tegory III onition, MUST e instlle in the fixe wiring. WARNING ONLY use opper wires. Mke sure the fiel wiring omplies with the pplile legisltion. All fiel wiring must e performe in orne with the wiring igrm supplie with the prout. NEVER squeeze unle les n mke sure they o not ome in ontt with the piping n shrp eges. Mke sure no externl pressure is pplie to the terminl onnetions. Mke sure to instll erth wiring. Do NOT erth the unit to utility pipe, surge sorer, or telephone erth. Inomplete erth my use eletril shok. Mke sure to use eite power iruit. NEVER use power supply shre y nother ppline. Mke sure to instll the require fuses or iruit rekers. Mke sure to instll n erth lekge protetor. Filure to o so my use eletri shok or fire. When instlling the erth lekge protetor, mke sure it is omptile with the inverter (resistnt to high frequeny eletri noise) to voi unneessry opening of the erth lekge protetor. Preutions when lying power wiring: Do not onnet wiring of ifferent thiknesses to the power terminl lok (slk in the power wiring my use norml het). When onneting wiring whih is the sme thikness, o s shown in the figure elow. For wiring, use the esignte power wire n onnet firmly, then seure to prevent outsie pressure eing exerte on the terminl or. Use n pproprite srewriver for tightening the terminl srews. A srewriver with smll he will mge the he n mke proper tightening impossile. Over-tightening the terminl srews my rek them. Instll power les t lest 1 metre wy from televisions or rios to prevent interferene. Depening on the rio wves, istne of 1 metre my not e suffiient. WARNING After finishing the eletril work, onfirm tht eh eletril omponent n terminl insie the eletril omponents ox is onnete seurely. Mke sure ll overs re lose efore strting up the unit. Only pplile if the power supply is three phse, n the ompressor hs n ON/OFF strting metho. If there exists the possiility of reverse phse fter momentry lk out n the power goes on n off while the prout is operting, tth reverse phse protetion iruit lolly.
