Kua whirihorahia te punaha me te raarangi whakatikatika me te valve hiko hei whakahaere i te punaha hau, me te aukati i nga paanga o te maripi me te pai o nga hua whakaraeraetanga.
A.Control me te whakaaturanga mamati: te whakamaroke i te waa whakarake me te waa taimaha ka taea te whakarite. (Ko te mahi o te tohu raka e whakaratohia ana, ka raka te aukati me te waa i muri i te waahi)
Ka taea te whakarite i te waa o te punaha, 'te hinu ngoikore: 1-999 hēkona ' Int 'Te wa mo te (1-999 hēkona)
B.Plc Mana: Te whakamarumaru me te ngoikore o te waa me te waa mo te wa e whakahaerehia ana e te PLC o waho.
C.NO te mana: Ko te whakamarumaru me te waatea me te waa mo te wa poto e whakahaerehia ana e te mana whakahaere.
Ka whakaratohia te huringa taumata wai. I te mea kaore i te rahi te taumata wai makariri, ka whakatangihia te kaihoroi, ka tuku i te tohu kore. (E whakaatuhia ana te Tari Arotake Mātauranga mēnā kaore i te rahi te taumata o te wai ki roto i te whakaaturanga mamati).
Ko te rama rama tohu tohu tohu e whakaatu ana i te mana o te mana.
Ko te pehanga o te punaha hau 0.4-0.6mpa e taunakitia ana.
Ko te diameter wai taunoa me te diameter haunga φ6
Ko te whakamarumaru o te ngakau whaiaro me te whakakao hinu ka whakamahia me te tauira EVA.
