The front position of auxiliary pipe is

stamped on the installation plate. 

It is used as a position mark when the 

piping is connected.

At a distance equal to the scale 

stamped on the installation plate 

you will find the center of rear piping 

hole. Engage the measure with the 

front holder of scale, and measure the 

distance.

For ø65, shift the center down by 3 

mm, and makle a hole.

The triangular dents (2 places) in the

center are for center positioning. which 

are usable for installing.

The hole in the center upper part has

-shape. After tentatively tightening

the screw, it is possible to ergage the 

installation plate here.
