Isiqandisi sidlala indima ebalulekile enqubweni yesiqandisi yokubuyisela kabusha isiqandisi samanzi. Isiqandisi samanje esilungele imvelo sihlanganisa u-R134A, u-R410A no-R407C. Uma abasebenzisi benesidingo esikhethekile mayelana nesiqandisi, bangaxhumana nomhlinzeki we-chiller ngokufanele.
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.
