How to Increase Manifold Bases (Series SY9000 only)
When a type 43 manifold base is added, tension bolts as well as manifold block assembly will be required. Order the tension bolt suitable for the
stations after a station was increased (decreased), since the length of a tension bolt differs by the number of stations. (For changing the number
of stations for a type 43P manifold, wiring unit for the stations and lead assembly will be required.)
By replacing manifold block fitting assemblies or the threaded port block assembly of a type 43(P) manifold, the port size of the A and B ports can
be changed. To replace these parts, remove the clip with a flat head screwdriver after the valve has been removed. Insert the fitting assemblies or
threaded port block assembly, and then reinsert the clip so that it does not protrude from the manifold block.
Fitting Assembly Part No.
Note 1) Be careful to avoid damage or contamination of O-rings, as this can cause air leakage.
Note 2) Although replacing One-touch fittings of P, R port is also possible, use caution to the cases, etc. in which solenoid

How to Replace A, B Port Fitting Assembly
Loosen the tension bolts connecting the manifold base, and pull out both of 2 tension bolts.
(When equipped with a DIN rail, loosen one DIN rail holding screw on either U side or D side.)
Separate the blocks at the location where station expansion is desired.
Mount additional manifold block assembly.
Press block-to-block so that there’s no gap. After connection, insert a tension bold for desired stations and then tighten it.

3. By adding wiring unit assembly to type 43 manifold, it can be changed to type 43P manifold, too.

valves are often used at the same time by using the smaller sized fittings than the standard size (ø12). Because there
may not be able to supply or exhaust air sufficiently in comparison with the valve performances. Besides, although
fittings used for A, B port are the same, it is not possible to use the threaded type port block assembly.
