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: If A siphon tue is present (i.e., the yliner is mrke with "Liqui filling siphon tthe") Then Chrge with the yliner upright. Mke sure the fiel piping n onnetions re NOT sujete to stress. During tests, NEVER pressurize the prout with pressure higher thn the mximum llowle pressure (s inite on the nmeplte of the unit). A siphon tue is NOT present Chrge with the yliner upsie own. Tke suffiient preutions in se of refrigernt lekge. If refrigernt gs leks, ventilte the re immeitely.

If you wnt to pump own the system, n there is lek 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. ALWAYS 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. Mke sure there is no oxygen in the system.

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 ove. 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. 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.
