I-manifold, eyaziwa nangokuthi i-distribution manifold, iyingxenye eyinhloko yesistimu yokushisa ngaphansi komhlaba. Ixhunywe ikakhulukazi kumapayipi amakhulu okuphakela nokubuyisela amanzi futhi ihlukanisa amanzi ashisayo kuzo zonke izixhumanisi zokushisa.

Uhlaka Oluyisisekelo Nezisebenzi: I-manifold iqukethe ipayipi elikhulu lokusabalalisa (elixhunywe kupayipi lokuhlinzeka) kanye nephepha elikhulu lokuqoqwa (elixhunywe kupayipi lokubuyisela). Ipayipi elikhulu lokusabalalisa lisabalalisa amanzi ashisayo kumapayipi okushisa aphansi egumbini ngalinye, kanti ipayipi elikhulu lokuqoqwa liqoqe amanzi abuyayo. Imisebenzi yayo eyinhloko ifaka phakathi ukucindezela, ukunciphisa ucindezelo, ukuzinza kocindezelo, nokusabalalisa ukuhamba ukuze kuqinisekiswe ukuhamba kwamanzi ashisayo okujwayelekile.

Izinsiza ngokuvamile zifaka ama-valve ebhola, ama-valve okulawula ukuhamba, izikhala zomoya, nezihlungi, ezisetshenziselwa ukulawula ukuhamba kwamanzi, ukususa umoya, nokuhlungela 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 okwenziwe ngezifunda, kanye nezici zokulawula kude, ezifanele izinhlelo eziphezulu.

Ngaphezu kwalokho, ngokusekelwe ekusebenzeni kokwakhiwa, ihlukaniswe ibe yizinguqulo zaseKorea nezaseYurophu: inguqulo yaseKorea inezakhiwo ezilula nezindleko eziphansi, ezifanele ukushisa okuyisisekelo ngaphansi komhlaba; inguqulo yaseYurophu inezici eziphelele kakhulu kanye nezinga eliphezulu lokuhlakanipha, ivamise ukusetshenziswa ezindlini eziphezulu noma ezinhlelweni zokushisa ezizimele.

**Izidingo Zokwakha Nokufaka:** Ukuze kuvinjwe ukugqwala, i-manifold ivamise ukwenziwa ngezinto ezivimbela ukugqwala ezifana ne-copper ehlanzekile noma insimbi engagqwali; insimbi yokuphonsa kufanele igwenywe. 1. Ngesikhathi sokufaka, kufanele ibekwe ngokuhlangene odongeni noma ebhokisini elikhethekile (njengokwakhiwa kokupheka). I-manifold kufanele ibe okungenani ama-30 cm phezulu komhlaba. Kufanele kufakwe ifilitha ekugcineni. Uhlelo lokuxhuma luyindlela elandelayo: ipayipi lokuhlinzeka → ivaliwe → ifilitha → i-manifold → ipayipi lokushisa ngaphansi komhlaba → ikholi → ipayipi lokubuyisela.

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