4.2.1 Tools
Tools might vary based on different installation surfaces.

Cement.
Percussion drill, drill No.16 and No. 32, marking pen, tape measure, spirit level, plumb bob (for
calibrating the levelness of the passage), hammer, wrench, angle grinder or cutting machine,
and screwdriver.

Marble and ceramic.
Because marble and ceramic grounds are fragile, use the pistol drill to drill a hole first, apply
cooling water, and then keep drilling until the hole is deep enough. Remove the dust inside the
hole with water, and then use the percussion drill for the dimensions you need.
4.2.2 Wiring

Check if the labels on the cables are clear. If not, make them clear.

AC power cables and communication cables cannot be on the same pipe.

PVC pipes should be buried under the ground for more than 150 mm to avoid damage from
expansion bolts. The pipe above the ground should be longer than 50 mm to keep water out.

The PVC pipes must be able to go through the cable entry of the installation base.
