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 wai o te pūnaha, tāpirihia te kukū o te waipiro etanoru neke atu i te 90%, 95% rānei 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 ko -1.℃, tāpirihia he 5 kg o te waipiro, ko te taupū ārai-huka he -5℃Me aro ki te whakamahinga o te etanoru i tāpirihia ki te pūnaha mō te ārai huka, me aro ki te nui o te wai e kore e 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, -25° C ° He ārai hukapapa C, engari nā te utu nui o te ārai hukapapa, ka piki ake te utu o te haumitanga tuatahi. I te whakamahinga o te ārai hukapapa, me tūpato kia kaua e whakamahia he utu iti, pērā i te ārai hukapapa kua whakaranua ki te methanol, ka waikura ki te paipa, ka nui ake te kino ki te takirere, ki ngā hononga paipa, ki ngā papu, ki ngā wae whakawhiti wera.
