(a) 6.2.1 IZIMALI ZEZInzwa ZETEMPELA
Lapho sinquma indawo yokufaka inzwa yokushisa, kufanele sinakeindawo yepayipi.Khona-ke indawo yepayipi kufanele ihlanzeke ngaphambi kokufaka inzwa yokushisasebenzisa amabhande ukulungisa inzwa yezinga lokushisa.
(b) 6.2.2 IFAKE IZInzwa ZETHEMSHA
Inzwa yokushisa yokufaka ithintana ngokuqondile noketshezi olulinganiselwe, ngakho ukunemba kwayongaphezulu.Sinezindlela ezimbili zokufaka inzwa yokushisa yokufaka.
1. Ukufakwa nge-valve yebhola
Ngempahla yepayipi ephathwayo, shisela i-valve yebhola epayipini ngqo.Okokusebenza kwamapayipi angaphatheki,okokuqala ngokushisela ihupho (Imvamisa impahla iyinsimbi ye-carbon) epayipini, bese ivula i-valve yebhola yokushiselaihuphu.Ngemva kokushisela i-valve yebhola, vula imbobo efanelekile.Gcoba odongeni lwamapayipi ngokuhambisana ne-imiyalelo ehlinzekwe ngomshini wokubhola, ekuqaleni, sicela ukhethe indawo yokuthepha kancane ukuzebhoboza imbobo, bese ukhetha indawo yokuthepha okusheshayo. 
Ngemva kokubhoboza imbobo, xhuma inzwa yokushisa yokufaka, lungisa ukujula kokufaka, beseLungisa.
2. Ukufaka epayipini ngqo
Gcoba imbobo efanele epayipini ngokuqondile, xhuma inzwa yokushisa yokufaka, lungisaukujula kokufakwa, bese ukukulungisa.
