Ehara te R22 i te hauhautanga taiao, nō reira kāore e taea te kaweake i te pouaka whakamatao wai e whakamahi ana i te R22 ki ngā whenua o Ūropi. Nō reira, he pai ake te whakamahi i te hauhautanga taiao mō te kaweake i te pouaka whakamatao wai. Mō te pouaka whakamatao wai porowhita S&A Teyu, kei te wātea ngā pouaka whakamatao taiao pēnei i te R134A, R410A me te R407C, kia kore ai koe e manukanuka ki te take kaweake.
Mō te hanga, kua whakangaohia e S&A Teyu te neke atu i te kotahi miriona RMB mō ngā taputapu hanga, hei whakarite i te kounga o te raupapa o ngā tukanga mai i ngā wāhanga matua (whakamātao) o te mīhini whakamatao ahumahi ki te whakarewa i te pepa whakarewa; mō te mahi kawe taonga, kua whakatūria e S&A Teyu ngā whare putunga kawe taonga i roto i ngā tāone nui o Haina, ā, kua tino whakaitihia te kino nā te kawe taonga tawhiti, me te whakapai ake i te whai huatanga o te kawe waka; mō te ratonga muri-hoko, ka hipokina e ngā mīhini whakamatao wai S&A Teyu katoa te Inihuarangatia o te Taunahatanga Hua, ā, e rua tau te roa o te wā whakamana hua.
