(1) Tautuhi kī: whakamahia mō te whakawhiti i waenganui i te mahi noa me te tautuhinga pāmahana. Pēhia te kī tautuhinga, ka whiti te ngongo matihiko ka uru ki te ahuatanga o te whakamahana (he mea motuhake te whakamahana me te pouaka whakamahana, kaua e tiritiri i te uara tautuhinga pāmahana kotahi). I tenei wa, pehia te paatene ki runga, ki raro ranei hei tautuhi i te pāmahana kia hiahia koe ki te uara pāmahana. Patohia ano te taviri tautuhinga, ka mutu te hiko o te ngongo matihiko, tiakina te pāmahana tautuhinga ka hoki ki te mahi noa. I roto i te ahua o te pāmahana, me te kore e pehi i tetahi taviri mo te 5 hēkona, ka tiakina aunoa e te thermostat te pāmahana kua whakaritea o naianei ka hoki ki te ahua rere.
(2) Patene ki runga: whakamahia hei whakanui ake i te pāmahana kua whakaritea
I roto i te ahua tautuhinga, pehia tenei paatene kia kotahi ki te whakarite i te pāmahana kia piki ake ma te 1 ℃. Purihia tenei patene hei whakanui tonu i te pāmahana tae noa ki te tepe o runga o te whakamahana, te pāmahana whakamatao ranei (he rereke te whakamahana i te tepe o runga o te pāmahana whakamatao).
(3) Patene Raro: whakamahia hei whakaheke i te pāmahana kua whakaritea
I roto i te ahua tautuhinga, pehia tenei paatene kia kotahi ki te tautuhi i te pāmahana kia whakahekehia e te 1 ℃. Purihia tenei patene ka taea te whakaheke haere tonu te pāmahana tae noa ki te tepe o raro o te whakamahana me te whakamahana whakamahana (he rereke te whakamahana i te tepe o raro o te pāmahana whakamatao).

Aratau mahi
Refrigeration: Ina ko te ≥ te pāmahana whakahaere i te pāmahana +1 ℃, whakakāhia te hiko kawenga; i te wa e ≤ te pāmahana whakahaere -1 ℃, whakawetohia te tuku hiko. E 3 meneti te roa ki te hiko i ia wa ka weto te miihini.
Te whakawera: Ina ko te ≥ te pāmahana whakahaere i te pāmahana +1 ℃, tapahia te tuku mana kawenga; i te wa e ≤ te mana whakahaere i te pāmahana -1 ℃, whakahurihia te hiko o te kawenga.

Paemahana Awhe:-35 ~ 55 ℃.
