1. Whakapakari i te pānga o te whakamarumaru o ngā paipa He mea tino nui te whakamahana i ngā paipa, ka whakamatao ngā paipa wai e kitea ana i te taiao o waho ina heke te pāmahana.
2. Kaua e momotu te waeine, te pūnaha wai pūtake hau papu wera, te wai hei takawaenga mō te whakawhiti wera. Mena he noa, he mahi ārai-huka kei te taputapu, ina iti te pāmahana wai ki tētahi pāmahana, ka tīmata aunoa te taputapu ki te aukati i te hukapapa o ngā taputapu me ngā paipa.
3. Me whakahaere tika te wai whakapūhau, ā, i te wā e whakamahana ana, ka nui te wai whakapūhau ka puta. Mēnā he iti noa te mangere i te tukunga o te wai whakapūhau, ka tukuna te wai whakapūhau ki waho mā te paipa, ka rere ki te whenua. Mēnā kei raro iho i te kore te pāmahana, ka ngāwari te huka o te wai whakapūhau, ā, tera pea ka huka te paipa waikeri, kātahi ka piki ake i te paipa waikeri, ā, ka mutu, ka kore e taea e ngā taputapu te mahi noa.Horoia te wai whakapūkara i ia wā.
4. Tāpirihia te waipiro etanoru ki roto i te wairewa o te pūnaha, tāpirihia te kukū o te neke atu i te 90%, te 95% rānei o te waipiro etanoru hei whakanui ake i ngā āhuatanga ārai-huka. Tāpirihia te tau, i runga i te pāmahana iti rawa o te rohe, pērā i te 100 rita o te kaha wai hei tāpiri i te 1 kg o te waipiro, ko tōna taupū ārai-huka he -1 ℃, tāpirihia te 5 kg o te waipiro ko tōna taupū ārai-huka he -5 ℃. Mō te whakamahinga o te etanoru i tāpirihia ki te pūnaha hei ārai-huka, me aro ki te nui o te wai kaua e neke atu i te 1 neke atu i te 40% o te pūnaha wai katoa.
5. Tāpirihia he ārai huka ki roto i te pūnaha, pērā i te -15°C°C, te -25°C°C te ārai huka, engari nā te nui o te utu o te ārai huka, ka piki ake te utu o te haumitanga tuatahi. I te whakamahinga o te ārai huka, me tūpato kia kaua e whakamahia he ārai huka iti te utu, pērā i te methanol te ranunga, ka waikura ki te paipa, ka pā ki te takirere, ki ngā hononga paipa, ki ngā papu, ki te wae whakawhiti wera ka nui ake te kino.
