1. Ngexesha lokusebenza kweimpompo ephantsi kwamanzi, ukuhamba kwamanzi akhoyo, i-voltmeter kunye namanzi kuya kuqwalaselwa rhoqo ukuqinisekisa ukubaimpompo ephantsi kwamanziisebenza phantsi kweemeko zokusebenza ezireyithiweyo.

2. I-valve iya kusetyenziselwa ukulungelelanisa ukuhamba kunye nentloko, kwaye umsebenzi ogqithisayo awuyi kuvunyelwa.
Misa umsebenzi ngoko nangoko phantsi kwayo nayiphi na imiqathango elandelayo:
1) Umsinga udlula ixabiso elilinganisiweyo kwi-voltage elinganisiweyo;
2) Ngaphantsi kwentloko elinganisiweyo, ukuhamba kuphantsi kakhulu kunoko phantsi kweemeko eziqhelekileyo;
3) Ukuxhatshazwa kwe-insulation kungaphantsi kwe-0.5 megohm;
4) Xa umgangatho wamanzi oguquguqukayo uhla kwimpompo yokufunxa;
5) Xa izixhobo zombane kunye neesekethe zingahambelani nemimiselo;
6) Xa impompo yombane inesandi ngokukhawuleza okanye i-vibration enkulu;
7) Xa ukhuseleko lokutshintsha rhoqo luhamba.

3. Jonga rhoqoimpompo ephantsi kwamanzi, khangela izixhobo zombane, ukulinganisa ukunyanzeliswa kwe-insulation rhoqo kwisiqingatha senyanga, kwaye ixabiso lokumelana aliyi kuba ngaphantsi kwe-0.5 megohm.

4. Ixesha ngalinye lokunkcenkceshela kunye nokunkcenkceshela (iiyure ezingama-2500) liya kubonelelwa ngokhuseleko lwesondlo, kwaye iindawo ezibuthathaka ezitshintshiweyo ziya kutshintshwa.
