Caution
1. Be sure to turn off the power and stop the supply of air before disassembly. Furthermore, since air may remain inside the actuator, piping, and manifold,
confirm that the air is completely exhausted before performing any work.
2. After assembly and disassembly, air leakage could occur if blocks are not well connected or a thread is not tightly fastened onto the end block. Before
supplying air, make sure that no gaps exist in between blocks and that the valve and block are tightly fastened onto the DIN rail. Also, make sure that air
is not leaking before use.
3. For the SJ3A6 series manifold with vacuum release valve with restrictor, there is no valve lock switch for connecting, so when mounting, tighten the
screws after checking that there are no gaps between valves.

U side
Press the
manifold.
Series
Loosen threads a, which are fixed onto the DIN rail (two
1
locations on one side).
[∗ To replace the DIN rail, also loosen the screws (2 loca-
tions) on the connector block.]
In the direction of the coil, slide the valve where the
2
station is desired to add and the valve lock switch on
each block.
If blocks are removed without completely releasing
the valve lock switch, the connection hook of that
switch could be damaged or deformed.
Install an additional valve or a SUP/EXH block on the DIN
3
rail.
2. Press the manifold in the arrow
direction and mount it on the rail.
A manifold equipped with a valve or a block can be
mounted on the DIN rail. However, a serial connector
block cannot be mounted on the DIN rail when it is con-
nected with another block; the serial connector block
must be mounted separately.

Press the valves and blocks to each other for
connection. Press the valve lock switch in the cylinder
port direction until it does not go any further. Fasten
threads a onto the DIN rail.
After fixing the connector block, fasten the threads on-
to the end block while holding it lightly by hand. This is
necessary to improve sealing.
1. Hook on the rail.
