FAQ
Q1. Pehea e koho ai ma waena o nā pae wela hana o -20~+70 degere a me -40~+85 degere ?
-20~+70 degere : He kūpono no nā lako hale maʻamau (e laʻa, nā lako hale, nā lako keʻena, nā mana ʻoihana e hana ana ma ka wela lumi).
-40~+85 degere : Pili i nā hiʻohiʻona kaiapuni koʻikoʻi (e laʻa, nā lako kamaʻilio ma waho, nā uila uila, nā ʻōnaehana ʻoihana ʻenehana). E hōʻoia i ka pili ʻana o ka pae wela hana maoli o ka hāmeʻa me kēia kikoʻī.
Q2. He aha ka manawa alakaʻi no ka lawe ʻana?
Lead Time: No nā ʻāpana maʻamau, loaʻa iā mākou ka waiwai a hiki ke hana i ka lawe ʻana i nā lā 1-2. Inā pau ka waihona, ʻo nā kumu hoʻohālike maʻamau e lawe i 1 ~ 2 pule.
