I-manifold, eyaziwa nangokuthi i-distribution manifold, iyingxenye eyinhloko yesistimu yokushisa ngaphansi komhlaba. Ikakhulukazi ixhuma amapayipi amakhulu okuphakelayo nokubuyisela amanzi futhi ihlukanisa amanzi ashisayo kuzo zonke izixhumanisi zokushisa.

Isakhiwo Esiyisisekelo Nezisebenzi: I-manifold iqukethe ipayipi elikhulu lokusabalalisa (elixhunywe nephayiphi yokuhlinzeka) kanye nephayiphi elikhulu lokuqoqwa (elixhunywe nephayiphi yokubuyisela). Ipayipi elikhulu lokusabalalisa lisabalalisa amanzi ashisayo kumapayipi okushisa aphansi egumbini ngalinye, kanti iphayi elikhulu lokuqoqwa liqoqe amanzi abuyayo. Imisebenzi yayo eyinhloko ifaka phakathi ukucindezela, ukunciphisa ucindezelo, ukuzinza kocindezelo, nokusabalalisa ukuhamba ukuze kuqinisekiswe ukuhamba kwamanzi ashisayo okulinganayo.

Izinsiza ngokuvamile zifaka ama-valve ebhola, ama-valve okulawula ukuhamba, izikhala zomoya, kanye nezihlungi, ezisetshenziselwa ukulawula ukuhamba kwamanzi, ukususa umoya, nokuhlunga izinto ezingcolile.

Ukuhlukaniswa Nezici: Ngokusekelwe emsebenzini nasestructure, ama-manifold angahlukaniswa abe izinhlobo ezintathu:

Uhlobo Oluyisisekelo: Luhlinzekwa nge-valve yebhola kanye nesikhala somoya esenziwa ngesandla, sinikeza kuphela ukulawula okuyisisekelo kokuvula/ukuvala ngaphandle kokulawula ukuhamba.

Uhlobo Olujwayelekile: Luthuthukiswe nge-valve yokulawula ukuhamba kanye ne-automatic air vent, evumela ukulungiswa okunembile kwesilinganiso sokuhamba kuzo zonke izixhumanisi; amamodeli athile asekelwa ukulungiswa okuhlakaniphile. **Uhlobo Olusebenza:** Luhlanganisa ukuboniswa kokushisa/nengcindezi, ukuhlanganiswa okuzenzakalelayo, ukukala ukushisa, ukulawula okukhona ezindaweni, kanye nezici zokulawula kude, ezifanele izinhlelo ezisezingeni eliphezulu.

Ngaphezu kwalokho, ngokusekelwe ekusebenzeni kokwakhiwa, ihlukaniswe kube nguMphakathi waseKorea kanye noMphakathi waseYurophu: uMphakathi waseKorea unokwakheka okulula kanye nezindleko eziphansi, ezifanele ukushisa okuyisisekelo ngaphansi komhlaba; uMphakathi waseYurophu unezici eziphelele kakhulu kanye nezinga eliphezulu lokuhlakanipha, ngokuvamile lisetshenziswa ezindlini ezisezingeni eliphezulu noma ezinhlelweni zokushisa ezizimele.

**Izidingo Zokwakha Nokufaka:** Ukuze kuvinjwe ukuvuvukala, i-manifold ivamise ukwenziwa ngezinto ezivimbela ukuvuvukala ezifana ne-copper ehlanzekile noma insimbi engagqwali; insimbi ye-cast kufanele igwenywe. 1. Ngesikhathi sokufaka, kufanele ibekwe ngokuhlangene odongeni noma ebhokisini elikhethekile (njengokwakhiwa kukakhukhunathi). I-manifold kufanele ibe okungenani ngama-30 cm phezulu komhlaba. Kufanele kufakwe ifilitha ekugcineni. Uhlelo lokuxhuma luwukuthi: ipayipi lokuhlinzeka → ivali ye-shut-off → ifilitha → i-manifold → ipayipi lokushisa ngaphansi komhlaba → ikholi → ipayipi lokubuyisela.

**Ukusetshenziswa Nokmaintenance:** Ngaphambi kokushisa unyaka nonyaka, ivali ye-air vent kufanele ivulwe ukuze kususwe umoya emaphaketheni. I-filter kufanele ihlanzwe njalo ukuze kugcinwe amaphakethe ehlanzekile. Uma ingasetshenziswa isikhathi eside, ivolumu yamanzi aphelile ingancishiswa. Ebusika, uma ukushisa kungasetshenziswa, amanzi emaphaketheni kufanele aphume ukuze kugwenywe ukujula nokuphuka. ‌
