Funda nomba ewu munda mua tshiibi tshieba tshia tshiamu tshia nzembu.
2. Malu adi kaayi makane mu lupitadi ne mu nzubu wa kapia: Nzubu miteka pa tshiamu tshimue tshia difila dia biakudia bu mudi lupitadi lua babedi badi ne masama a lufu, nzubu wa dilengeja mâyi anyi nzubu wa kapia itu misangu ya bungi kayiyi ne bua kuenza mudimu ne mashinyi adi enda ashintuluka, nansha mudibi kabiyi bijadikibua mu tshikondo tshia njiwu mikole ya nzembu.
3. Dilongolola dia batterie ya kumpala kua mashika ne ya kapia kumpala kua tshitupa tshieba:
   • Mêba 2 kumpala kua tshikondo tshia dijika dia kapia: Teka tshiamu tshieba tshia luya ku 2 to ne ku 3 degrés Celsius (4 to ne ku 6 degrés Fahrenheit) mashika kupita pa tshibidilu bua kulongolola tshimanu ne bintu bia mu nzubu muebe, pashishe kanga AC OFF minite 10 kumpala kua dîba ku ndekelu bua compresseur kayi wenza mudimu padi tshiamu tshia kujika natshi luya tshiunzuluka.
   • Uwuja muaba udi kauyi ne tshintu mu tshikuku tshiebe ne mu frigo ne milondo ya mayi: Milondo ya plastique miule tente ne bitupa bisatu bia binayi bia mâyi a mu pompi adi ne mashika idi yenza mudimu bu ma batterie a kapia adi avula misangu ibidi dîba dia kulama mashika a mu tshikuku tshiebe ne mu frigo webe.
   • Epuka biamu bia kubandisha nabi bantu minite 15 kumpala kua kuulu ne kuinshi kua dîba dionso: Dijimija dia bujitu dia bintu didi dienzeka pabuipi ne kuulu (:00) anyi kuinshi (:30) wa dîba. Kubuedi nansha kakese mu ascenseur mu tshikondo tshia madimuija a brownout; mona wetu malu a tshimpitshimpi a ascenseur mulombodi pikala mukuatshike.

Dijikija dia lutatu lua tshimpitshimpi: Shi tshiamu katshiena mua kutuadija mudimu kunyima kua dijika dia nzembu¶

Shi nzembu ya nzembu mimane kufika ku 120 volts (anyi 230 volts) ne tshiamu tshia compresseur tshibenga kutuadija anyi tshipuekesha kapepe ka kapia, enza Dikonkonona dia dipingaja dia luya lua bungi edi:

1. Tshiamu tshia munda tshia minite 45 tshidi tshikuba kapia¶

Tshiamu tshionso tshia frigo, tshiamu tshia mashika, ne tshiamu tshia AC tshidi ne bi-metallic thermal overload protector tshiteka pa tshiamu tshia compressor. - Shi tshiamu tshia nzembu tshidi tshiteta bua kutuadija mu tshikondo tshia nzembu ne tshinyanguka pa Locked Rotor Amps, tshitupa tshia munda tshia tshiamu tshia nzembu tshidi mua kufika ku 105 too ne ku 130 degre Celsius (221 to ne 266 degre Fahrenheit) ne tshipatula kapia bitekete bitekete munda mua tshiamu tshia vacuum. Nansha mudi nzembu mimane kupingana, tshiamu tshia thermal overload tshidi tshishala tshiunzulula too ne padi tshiamu tshia motere tshifika ku 65 degrés Celsius (150 degrés Fahrenheit). - Tshia kuenza: Umbusha frigo anyi upuekesha tshiamu tshia AC OFF bua minite 45 too ne ku 60 (kulama biibi bikanga) bua luya lukole luleke kuendakana ne tshibumba tshia compresseur tshifike ku mashika. Panyima pa minite 60, udi mua kutshisangisha kabidi; misangu ya bungi, tshiamu tshia mashika tshidi tshituadija diakamue.

2. Kupingaja GFCI / AFCI ne kutangila tshiamu tshia HVAC tshia pambelu¶

• Tangila bipese bia GFCI ne bipese bia AFCI: Bipese bia dilongolola bidi binyanguka misangu ya bungi Ground Fault Circuit Interruptor (GFCI) mu nzubu ya mashinyi, mu nzubu ya muinshi mua buloba, ne mu bikuku, anyi bipese bia Arc Fault (AFCI). Fina RESET tshishindame pa tshiamu tshionso tshia GFCI, ne ushintulule biamu bia dikosa nabi nzembu too ne ku OFF ne kupingana ku ON.
• Tangila bua se HVAC Dual-Run Capacitor udi mupatuke: Shi tshiamu tshieba tshia mu nzubu tshidi tshienza mudimu bimpa, tshiamu tshieba tshia pambelu tshienza mutoyi, ne nzubu wela kapepe ka luya kunyima kua dijika dia kapepe, bualu budi butamba kuenzeka mbua aluminium Dual-Run Start/Run Capacitor munda mua tshiamu tshia condenser tshia pambelu. Mafuta a nzembu makese adi akolesha mafuta adi munda mua biamu bia tshiamu tshia aluminium, bienza bua mutu wa tshibombi tshia tshiamu tshilue kuulu bu tshibombi tshia soda tshidi tshikole**, ne tshidi tshipangisha tshibombi tshia munda. Muena mudimu wa HVAC udi ne mukanda udi mua kupingaja capacitor mu minite 15.

Nkonko itubu bela misangu ya bungi¶
