1. Kuseŵezeska vyakukhumbikwa vya chilengiwa.
a) Kutentha: 5-40 digiri .
b) Chinyezi chakukolerana: Kuchepa panji kufanana na 85% .
c) Nkhongono ya kupereka magesi: AC220V ± 10%.
d) Palije kugwedezeka kwakukhora na mphepo za dzimbiri kuzungulira .
2. Kufunyapo kwa mphepo yakuzizima.
a) Mujalire chipata na kukhozga chikhodzodzo mu malo ghake, kujara vavu ya ndopa (kuti chibowo icho chili pa pulagi ya labala na chibowo pa vavu ya ndopa vikapotoloka 90℃), julani vavu ya vacuum (kuzungulira 90 degreeclockswise), nyengo yakwamba iyo mukugwiliskira ntchito vavu ya vacuum yingaŵa yakukhora kuti musinthe, mungakakamizga kusintha.
b) Gwiliskirani nchito chitoliro cha kulumikizgana kwa vacuum (mkati mwa mukati: Φ16mm msinkhu wa khoma: 10mm) kuti mulumikizge pampu ya vacuum (dimenti yakunja: Φ16mm) na pampu ya vacuum (2XZ-2 mtundu, mtundu wa diameter yakunja Φ16mm) na chinthu cha mwamwaŵi (6090 na 6210 mtundu walumikizgika). Ŵikani pa nkhongono ya mpope ya vacuum na kwamba kupopa, para vacuum gauge yafika -0.1Mpa, kujara vacuum valve dankha ndipo pamanyuma pake kuzimya nkhongono ya pampu ya vacuum kuti pampu ya vacuum yileke kusefukira mu chipinda chakugwilira ntchito (Model 6090 na 6210 mulije vacuum valve, ntheura mungazimika nkhongono ya vacuum pa panel) pa nyengo iyi, bokosi lili mu vacuum state{12}}
