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

Isakhiwo Esiyisisekelo Nezisebenzi: I-manifold iqukethe iphayiphi elikhulu lokusabalalisa (elixhunywe nephayiphi lokuhlinzeka) kanye nephayiphi elikhulu lokuqoqwa (elixhunywe nephayiphi lokubuyisela). Ipayiphi elikhulu lokusabalalisa lisabalalisa amanzi ashisayo kumapayiphi okushisa aphansi egumbini ngalinye, kanti iphayiphi elikhulu lokuqoqwa liqoqe amanzi abuyiselwa. Imisebenzi yayo eyinhloko ifaka phakathi ukujolisa, ukujolisa, ukuzinza kwengcindezi, nokusabalalisa ukuhamba ukuze kuqinisekiswe ukuhamba kwamanzi ashisayo ngokulinganayo.

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

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

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

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

Ngaphezu kwalokho, ngokusekelwe ekusebenzeni kokwakhiwa, ihlukaniswe ngezinhlobo 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 ezisezingeni eliphezulu noma ezinhlelweni zokushisa ezizimele.

**Izidingo Zokwakha Nokufaka:** Ukuze kuvinjwe ukuwohloka, i-manifold ivamise ukwenziwa ngezinto ezivimbela ukuwohloka 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 luyi: ipayipi lokuhlinzeka → ivali ye-shut-off → ifilitha → i-manifold → ipayipi lokushisa ngaphansi komhlaba → ikholi → ipayipi lokubuyisela.

**Ukusetshenziswa Nok maintenance:** Ngaphambi kokushisa unyaka nonyaka, ivali ye-vent ye-air 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. ‌
