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.

5. Phambi kokufaka i-FFU, beka isihluzo se-hepa entsha kwindawo eqaqambileyo, kwaye ujonge ukuba isihluzo se-hepa sonakaliswe ngenxa yothutho kunye nezinye izizathu.Ukuba iphepha lokucoca linemingxuma, alinakusetyenziswa.
6. Xa indawo yokucoca i-hepa, ibhokisi kufuneka iphakanyiswe kuqala, emva koko ayiphumelelanga isihluzo se-hepa kufuneka sikhutshwe, kwaye isihluzo se-hepa 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.
