I-manifold, eyaziwa nangokuthi i-distribution manifold, iyingxenye eyinhloko yesistimu yokushisa ngaphansi komhlaba. Ikhombisa ikakhulu ukuhlanganisa amaphayiphi amakhulu okuphakelayo 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 iphayi lokuqoqwa liqoqe amanzi abuyayo. Imisebenzi yayo eyinhloko ifaka phakathi ukucindezela, ukunciphisa ukucindezela, ukuzinza kwengcindezi, nokusabalalisa ukuhamba ukuze kuqinisekiswe ukuhamba kwamanzi ashisayo okujwayelekile.

Izinsiza ngokuvamile zifaka phakathi 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-manifold angahlukaniswa abe izinhlobo ezintathu:

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

Uhlobo Olujwayelekile: Luphucuziwe ngevalvu yokulawula ukuhamba kanye ne-automatic air vent, evumela ukulungiswa okunembile kwejubane lokuhamba kuzo zonke izixhumanisi; emamodelini athile asekelwa ukulungiswa okuhlakaniphile. **Uhlobo Lokusebenza:** Luhlanganisa ukukhombisa okushisa/pressure, ukuhlanganiswa okuzenzakalelayo, ukukala ukushisa, ukulawula okushisayo okwenziwe ngendawo, kanye nezici zokulawula kude, ezifanele izinhlelo ezisezingeni eliphezulu.

Ngaphezu kwalokho, ngokusekelwe ekwakhiweni kokusebenza, ihlukaniswe kube nguMoya waseKorea noMoya waseYurophu: uMoya waseKorea unokwakheka okulula kanye nezindleko eziphansi, ezifanele ukushisa okuyisisekelo ngaphansi komhlaba; uMoya waseYurophu unezici eziphelele kakhulu kanye nezinga eliphezulu lokuhlakanipha, ngokuvamile usebenza ezindlini ezisezingeni eliphezulu noma ezinhlelweni zokushisa ezizimele.

**Izidingo Zokwakha Nokufaka:** Ukuze kuvinjwe ukugqwala, i-manifold ivamise ukwenziwa ngezinto ezivimbela ukugqwala ezifana ne-copper ehlanzekile noma insimbi engagqwali; i-cast iron kufanele igwenywe. 1. Ngesikhathi sokufaka, kufanele ibekwe ngokuhlangene odongeni noma ebhokisini elikhethekile (njengokwakhiwa kokupheka). 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-vent ye-air kufanele ivulwe ukuze kukhishwe umoya emaphaketheni. I-filter kufanele ihlanzwe njalo ukuze kugcinwe amaphakethe ehlanzekile. Uma ingasetshenziswa isikhathi eside, ivolumu yamanzi edluliswayo ingancishiswa. Ebusika, uma ukushisa kungasetshenziswa, amanzi emaphaketheni kufanele aphume ukuze kugwenywe ukujula nokuphuka. ‌
