Dismantling the inverter (see fig. 8)

A) Ensure that the power supply cable is disconnected from the mains..
B) Unscrew the 12 screws located at the four corners of the two blak plastic shells.
C) Slide out firstly the upper shell and then the lower shell.
D) Unscrew the two screws located below the wording "Technology TIG 165 "on the inverter side panel (13 , 14).
E) Slide out the casing by gently pulling it upwards.
F)

Once you have completed the repair, proceed in reverse order to re-fit the casing and the shells, ensuring that the fold on the

upper part of the shell is fitted inside the frame and the lower part of the side walls is fitted outside the frame.

The instruments with codes can be supplied by TELWIN. Sale price on request.
