1.Fitting of the Mounting Plate and Positioning of the wall Hole

When the mounting plate is first fixed

1.Carry out, based on the neighboring pillars or lintels, a proper leveling for the plate to be fixed against the wall, then temporarily fasten the plate with one steel nail.

2.Make sure once more the proper level of the plate, by hanging a thread with a weight from the central top of the plate, then fasten securely the plate with the attachment steel nail.

3.Find the wall hole location A using a measuring tape

70mm

A=155mm

When the mounting plate is fixed side bar and lintel

Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten

the plate to the fixed mounting bar.

Refer to the previous article, " When the mounting plate is first fixed ", for the position of wall hole.

2.Making a Hole on the Wall and Fitting the Piping Hole Cover

Make a hole of 70 mm in diameter, slightly descending to outside the wall.

Install piping hole cover and seal it off with putty after installation
