6. Ní féidir le hardaitheoir an chaidéil uisce a bheith ró-íseal. Seachas sin, is gá comhla geata a shuiteáil ar phíblíne uisce an tobair chun sreabhadh an chaidéil ag an bpointe sreafa rátáilte a rialú chun an mótar a chosc ó ró-ualach agus a dhó mar gheall ar rátaí sreafa móra.
7. Nuair a bhíonn an caidéal uisce ag rith, ba cheart go mbeadh an t-aschur uisce leanúnach agus fiú, ba cheart go mbeadh an sruth cobhsaí (faoi choinníollacha oibre rátáilte, go ginearálta gan níos mó ná 10% den sruth rátáilte), agus níor cheart go mbeadh aon chreathadh nó torann ann. Má tá aon neamhghnáchaíocht ann, ba chóir an meaisín a stopadh chun an chúis a fháil amach agus é a dhíchur.
8. Nuair a shuiteáil tú, tabhair aird ar shocrú na sreinge talún mótair (féach Fíor 2). Nuair is píopa cruach é an píopa uisce, déan é a threorú as clamp an tobair; nuair is píopa plaisteach an píopa uisce, é a threorú ó mharc talún an chaidéil leictreach.
