1. Faka endaweni ye-FFU i-hepa filter ngokococeko lokusingqongileyo (izihluzi eziphambili zitshintshwa rhoqo emva kweenyanga ezi-1-6, izihluzi ze-hepa zitshintshwa rhoqo emva kweenyanga ezi-6-12; izihluzo ze-hepa azihlambeki).
2. Ukulinganisa rhoqo ukucoceka kwendawo ecocekileyo ehlanjululwayo ngulo mveliso rhoqo emva kweenyanga ezimbini usebenzisa i-particle counter. Ukuba umgangatho wokucoceka olinganisiweyo awuhambisani nenqanaba lococeko olufunekayo, phanda isizathu (ukuvuza, ukungaphumeleli kwe-hepa filter, njl.). Ukuba isihluzo se-hepa asiphumelelanga, yibuyisele ngesitsha.
3. I-FFU kufuneka ivalwe xa kutshintshwa i-hepa filter kunye ne-primary filter.
4. Xa utshintsha isihluzo se-hepa kwiyunithi yokucoca fan ye-FFU, nikela ingqalelo ekhethekileyo ekuqinisekiseni ukuba iphepha lokucoca lilungile ngexesha lokukhutshwa, ukuthuthwa kunye nokufakwa. Ungalichukumisi iphepha lokucoca ngezandla zakho, ezinokubangela umonakalo.
5. Ngaphambi kokufaka i-FFU, bamba i-hepa filter entsha kwindawo eqaqambileyo kwaye uyihlole ngokubonakalayo umonakalo owenziwe kuthutho okanye ezinye izinto. Ukuba iphepha lokucoca linemingxuma, alinakusetyenziswa.
6. Xa ubuyisela icebo lokucoca i-hepa ye-FFU, kufuneka uqale uphakamise ibhokisi, emva koko ukhuphe isihluzo se-hepa esingaphumelelanga kwaye usibuyisele kwisihluzo se-hepa entsha (qaphela ukuba uphawu lotolo lokuhamba komoya kwisihluzo se-hepa kufuneka luhambelane nolwalathiso lokuhamba komoya lweyunithi yokucoca fan ye-FFU). Emva kokuqinisekisa ukuba isakhelo sitywinwe, buyisela isigqubuthelo sebhokisi endaweni.
