holes on the installation board.
Drill four holes of 12mm, 45~50mm deep at the selected
positions on the ceiling. Then embed the expansible hooks .
Face the concave side of the installation hooks toward the
expansible hooks. Determine the length of the installation
hooks from the height of ceiling, then cut off the unnecessary

evenly, to ensure the balance of the body.
If the drainpipe is awry, leakage will be caused by the
malfunction of the water-level switch.
Adjust the position to ensure the gaps between the body and
the four sides of ceiling are even. The body's lower part
should sink into the ceiling for 10~12 mm (refer to Fig. 4-9).
