Kwenzeka kakhulu ukuthi amanzi ajikelezayo ku-chiller yamanzi aba yiqhwa ngenxa yezinga lokushisa eliphansi ebusika, okuvimbela isibandisi samanzi singasebenzi ngendlela evamile. Ngokuxazulula le nkinga, abasebenzisi bangakwazi ukwengeza isiqandisi kwisiqandisi samanzi ngokulandela lezi zinyathelo ezingezansi:
1. Faka amanzi afudumele ukuze uncibilikise iqhwa emgwaqeni wamanzi ojikelezayo;2. Ngemva kokuba iqhwa lincibilika, engeza i-anti-freezer ngokulingana.
Kodwa-ke, sicela uqaphele ukuthi i-anti-freezer ayikwazi ukusetshenziswa isikhathi eside, njengoba ingalimaza isiqandisi samanzi ngaphakathi ngenxa yokugqwala kwayo. Ngakho-ke, lapho isimo sezulu siqala ukufudumala futhi amanzi engabandi, kuphakanyiswa ukuthi kukhishwe amanzi ajikelezayo ngesiqandisi futhi uphinde ugcwalise amanzi ahlanzekile noma amanzi acwecwe.
Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
