1 Iindidi ezisibhozo zokutshiza:
Uhlobo lokutshiza lwekholamu erhabaxa;Isitshizi esimile okwefeni;Isitshizi seshawari;
Isitshizi samanzi kwikholamu ebhityileyo;i-perfusion enkulu;isitshizi samanzi semigca emininzi;isitshizi samanzi esisetyhula;ukutshiza amanzi ngokuthe ngqo
2 ukulungiswa kwamahhala komthamo wamanzi
Jikelezisa ukulungelelanisa umthamo wamanzi njengoko uthanda
3 ngokuhambelana noyilo lomzimba womntu
Ngokoyilo lwe-ergonomic, imigca egudileyo, imvakalelo ekhululekile yesandla
Iintloko zemipu ezi-4 ezinemisebenzi emininzi
Intloko yompu yemisebenzi emininzi, jikeleza ukutshiza amanzi ahlukeneyo, lawula ngokukhululekileyo umpu wamanzi
