1. He mea hou a kūpono hoʻi i ka hoʻolālā ʻana o ka valve butterfly ventilation, kū hoʻokahi i ke ʻano, māmā i ke kaumaha a wikiwiki hoʻi i ka wehe ʻana a me ka pani ʻana.
2. Loaʻa i ka valve butterfly ka maikaʻi o ka manawa hana liʻiliʻi, ka hana maʻalahi a me ka mālama hana akamai.
3. Ke hoʻohana nei i nā mea kūpono e hālāwai me nā mahana like ʻole o ka media haʻahaʻa, waena a kiʻekiʻe a me nā media corrosive.
4. ʻAʻohe lāʻau hoʻohui, bolts, a me nā mea ʻē aʻe, ka hana hilinaʻi, ke ola lawelawe lōʻihi, ʻaʻole i hoʻopilikia ʻia e ke ala kahe o ka media.
