tightened too much, the silencer may be damaged.
Please follow the procedures below for mounting.
When the body (case) is made of resin
Hold the tip of the main body (side without thread) and screw in.
At the point where the thread begins to feel tight, use a wrench
on the hexagonal flats to tighten an additional 1/4 turn.
Tighten securely by hand for AN103-01.
For BC element
Hold the tip of the main body (side without thread) with fingers
and screw in tightly.
Do not hold the part of sintered metal with a wrench, etc. to
tighten.
When the main body is made of metal (Except BC
element) [Series 25]
Within the recommended tightening torque shown in the chart
below, use a wrench on the hexagonal flats and tighten.
Tightening by using a pipe wrench or pliers may cause
damage to the silencer. This method is not recommended.

Make sure to verify the operating conditions of the actuator at
least once a day.
