1. Shintsha isihlungi se-FFU hepa ngokuya ngokuhlanzeka kwendawo ezungezile (izihlungi eziyinhloko ngokuvamile zishintshwa njalo ezinyangeni ezi-1-6, izihlungi ze-hepa ngokuvamile zishintshwa njalo ezinyangeni ezi-6-12; izihlungi ze-hepa azihlanzwa).
2. Kala njalo ukuhlanzeka kwendawo ehlanzekile ehlanzwa yilo mkhiqizo njalo ezinyangeni ezimbili usebenzisa i-particle counter. Uma izinga lokuhlanzeka elilinganisiwe lingahlangabezani nezinga lokuhlanzeka elidingekayo, hlola imbangela (ukuvuza, ukwehluleka kwesihlungi se-hepa, njll.). Uma isihlungi se-hepa sehlulekile, sishintshe ngesisha.
3. I-FFU kufanele ivalwe uma kufakwa isihlungi se-hepa kanye nesihlungi esiyinhloko.
4. Uma ushintsha isihlungi se-hepa kuyunithi yesihlungi se-FFU fan, naka kakhulu ukuqinisekisa ukuthi iphepha lesihlungi liphelele ngesikhathi sokukhipha, ukuhambisa, nokufaka. Ungathinti iphepha lesihlungi ngezandla zakho, okungadala umonakalo.
5. Ngaphambi kokufaka i-FFU, bamba isihlungi esisha se-hepa endaweni ekhanyayo bese usihlola ngokubonakalayo ukuthi asiboni umonakalo obangelwe ukuthuthwa noma ezinye izinto. Uma iphepha lesihlungi linezimbobo, alikwazi ukusetshenziswa.
6. Uma ushintsha isihlungi se-hepa se-FFU, kufanele uqale uphakamise ibhokisi, bese ukhipha isihlungi se-hepa esihlulekile bese usifaka isihlungi esisha se-hepa (qaphela ukuthi uphawu lomcibisholo womoya osihlungini se-hepa kufanele luhambisane nesiqondiso sokugeleza komoya seyunithi yesihlungi se-FFU fan). Ngemva kokuqinisekisa ukuthi uhlaka luvaliwe, buyisela isembozo sebhokisi endaweni yaso.
