M'malo ofulumira a zomangamanga zamalonda ndi kasamalidwe ka malo, nthawi ndi kudalirika ndizofunikira ndalama. Apa ndi pamenemavavu a mpira othamangawala. Kapangidwe kake ndi koyenera kwambiri pakuyika kwakukulu, monga mahotela, zipatala, ndi maofesi, komwe madzi osasunthika komanso magwiridwe antchito a HVAC sangakambirane.
Phindu lalikulu ndi liwiro la kukhazikitsa. Wogwira ntchito m'modzi atha kuteteza kulumikizana koyenera kwa atolankhani mumasekondi, kufulumizitsa kwambiri nthawi ya polojekiti poyerekeza ndi ulusi kapena kusaka. Liwiro ili silisokoneza khalidwe; mafupa ndi amphamvu, kugonjetsedwa ndi kukokera kunja, ndi chitetezo ku nkhawa matenthedwe kuti zingakhudze olowa soldered. Kukonzekera kumakonzedwanso. Pomwe thupi la valavu limamangiriridwa kosatha, makina osinthika amtundu wa cartridge amalola kutumikiridwa mosavuta popanda kudula chitoliro. Kwa oyang'anira malo, izi zikutanthauza kuchepa pang'ono panthawi yokonza. Potchula ma valve okonzanso kapena kumanga kwatsopano, kusankhamavavu a mpira othamangaimapereka yankho lotsimikizira zamtsogolo lomwe limalinganiza kuchita bwino kwanthawi yayitali ndi ntchito yayitali, yopanda mavuto.
