1. Ngokococeko lokusingqongileyo, buyisela isihluzo seyunithi yokucoca fan ye-ffu. Isihluzi sangaphambili siba ziinyanga ezi-1-6, kwaye isihluzo se-hepa siqhelekile kwiinyanga ezi-6-12 kwaye asinakucocwa.
2. Sebenzisa i-particle particle counter ukulinganisa ukucoceka kwendawo ecocekileyo ehlanjululwa yile ffu kanye kwiinyanga ezimbini. Xa ucoceko olulinganisiweyo aluhambelani nococeko olufunekayo, kufuneka ufumane isizathu sokuba kukho ukuvuza, nokuba isihluzo se-hepa asiphumelelanga, njl.
3. Xa utshintsha i-hepa filter kunye ne-primary filter, yeka i-fu.
4. Xa utshintshela i-hepa filter, kufuneka kuhlawulwe ingqalelo ekhethekileyo ukuze kuqinisekiswe ukuba iphepha lokucoca lilungile ngexesha lokukhupha, ukuphatha, ukufakwa kunye nokuthatha, kwaye akuvumelekanga ukuchukumisa iphepha lokucoca ngesandla ukwenza umonakalo.
5. Phambi kokufaka i-FFU, beka isihluzo se-hepa entsha kwindawo eqaqambileyo, kwaye uqaphele ukuba isihluzo se-hepa sonakaliswe ngenxa yothutho kunye nezinye izizathu. Ukuba iphepha lokucoca linemingxuma, alinakusetyenziswa.
6. Xa indawo yokucoca ihepa, ibhokisi kufuneka iphakanyiswe kuqala, emva koko ayiphumelelanga isihluzo sehepa kufuneka sikhutshwe, kwaye isihluzo sehepa entsha kufuneka itshintshwe. Qaphela ukuba uphawu lotolo lokuhamba komoya lwe-hepa lokucoca kufuneka luhambelane necala lokuhamba komoya leyunithi ye-ffu. Qinisekisa ukuba isakhelo sivaliwe kwaye uphinde ubeke isiciko endaweni.
