Umyalelo woFakelo
1. Nceda uqinisekise yonke imilinganiselo enjengemingxunya yemingxunya kunye nemigama yokugrumba kwiFig. 1 kuyahlangatyezwana nayo ngaphambi kokufaka ihenjisi.
2. Nceda uqinisekise ukuba umgama phakathi kwepaneli yomnyango kunye nekhabhathi yi-6mm ngaphambi kokufaka isitya sesiseko. Iihenjisi kunye nomphetho womnyango kufuneka ungqinelane. (Ikhiwane. 2)

Ukuqwalaselwa kofakelo
Ubuchule bokufaka iihenjisi ezimbini nangaphezulu
1. Tshixa zonke iihenjisi kwiipleyiti ezisisiseko (Ikhiwane. 3).
2. tyhala ingalo yehenjisi 1 no-4 phantsi (umzobo 4) de kuvakale isandi 'sokucofa' ukulungisa umnyango.
3. Cinezela ingalo 2 kunye no-3 ukugqibezela ufakelo.

Ukuba ubukhulu bepaneli yomnyango bukhulu kune-24mm
1. Nceda ukhulule ihinji (ngokwewotshi) ukuya kubuninzi bayo (Ikhiwane. 5).
2. Tshixa zonke iihenjisi kwiipleyiti ezisisiseko (Ikhiwane. 3).
3. Tyhala ihenjisi yengalo 1 no-4 phantsi (Ikhiwane. 4) kude kuvakale isandi esithi “cofa” ukulungisa umnyango.
Cofa kwihenjisi yengalo yesi-2 neyesi-3 de kuvakale isandi esithi “cofa”.
5. Lungisa ihenjisi yehenjisi kwindawo yayo efanelekileyo.
6.Ukuhlisa ipaneli yomnyango: ukhulule ihenjisi (ngokwewotshi) ukuya kubuninzi obunokubakho (Ikhiwane. 6) kwaye uvule zonke iingalo zehenjisi ukuhlangula ipaneli yomnyango.
