4.1 Idizayini elula nokusetha okungenamsebenzi.
4.2 Umthamo womoya omkhulu kanye nokuhluka okuncane kwezinga lokushisa lomoya.
4.3 Ishubhu yefin yensimbi engenasici kagesi ehlala isikhathi eside.
4.4 Amashubhu e-Steel-aluminium fin anezinga eliphezulu lokushintshisana ngokushisa kahle. I-tube eyisisekelo yenziwe nge-tube engenamthungo 8163, ekwazi ukumelana nengcindezi futhi ihlala isikhathi eside;
4.5 Ivalvu yesitimu kagesi ilawula ukungenisa, ukuvala ngokuzenzakalelayo noma ukuvuleka ngokusekelwe kumazinga okushisa asethiwe, ngaleyo ndlela kuqinisekiswe ukulawulwa kwezinga lokushisa okunembile.
4.6 I-Ventilator ingavikeleki emazingeni okushisa aphezulu kanye nokuswakama okuphezulu, ngesilinganiso sokuvikela se-IP54 kanye nesilinganiso sokufakwa kwe-H-class.
4.7 Ukuhlanganiswa kwesistimu yokususa umswakama nomoya omusha kubangela ukulahlekelwa ukushisa okuncane ngokuphawulekayo ngomshini wokuvuselela ukushisa okulahlwayo.
4.8 Ukugcwalisa ngokuzenzakalelayo umoya omusha.
