Hoʻohana nui ʻia ma luna o nā paipu no ka kānana aila a i ʻole nā wai ʻē aʻe, ka hale kila kalapona a me ka hīnaʻi kānana kila. ʻO ka hana nui o nā mea hana ʻo ia ka wehe ʻana i nā ʻāpana nui (coarse filtration), hoʻomaʻemaʻe i ka wai, a pale i nā mea koʻikoʻi.
Hoʻopili ʻia nā kānana hīnaʻi 2 e nā valves.
ʻOiai e hoʻohana ʻia ana kekahi o ka kānana, hiki ke pani ʻia kekahi no ka hoʻomaʻemaʻe ʻana, ʻo ia hoʻi.
Pono kēia hoʻolālā no nā noi e koi ana i ka kānana mau.
Mea ʻai meaʻai, maʻalahi ke ʻano, maʻalahi e hoʻouka, hana, wehe a mālama. ʻO nā ʻāpana liʻiliʻi liʻiliʻi, haʻahaʻa ka hana a me nā kumukūʻai mālama.
Hoʻokumu ʻia nā kānana mākēneki me nā mea magnetic ikaika a me kahi pale kānana pale. He ʻumi ka nui o ka ikaika adhesive o nā mea magnetic maʻamau a hiki iā lākou ke hoʻopili i nā mea haumia ferromagnetic nui micrometer i kahi hopena kahe wai a i ʻole ke kūlana kahe kiʻekiʻe. Ke hele nā mea haumia ferromagnetic i ka hydraulic medium ma waena o nā apo hao, hoʻopili ʻia lākou i nā apo hao, a laila e loaʻa ai ka hopena kānana.
