[To increase the number of stations from an odd
number (1, 3, 5, 7) to an even number (2, 4, 6, 8)]
(Odd numbered stations have a vacant lead wire for one
station, so additional orders are not required.)
1) Remove the tension bolt.
2) Remove end plate U.
3) Remove the valve assembly from the single unit for manifold
to be added.
4) Remove the switch assembly if there is one. (Be careful not
to drop the O-ring. Refer to .)
5) Remove junction box B (top) using a precision screwdriver.
(Refer to .)
6) Mount the extra connector to junction box B. (Refer to
.) (Engage the recess of the connector and the
protruding part of junction box B. Refer to .)
7) Mount the single unit for manifold to be added to the end sur-
face on the U side.
8) Mount end plate U with tension bolts of the appropriate
length for the number of stations required. (Tightening
torque: 0.75 N·m)
9) Mount junction box B to junction box A.
10) Mount the valve assembly. (Tightening torque: 0.15 N·m)
11) For products with a switch, mount the switch assembly. (Be
careful not to drop the O-ring. Tightening torque: 0.08 to 0.10
N·m)
[To increase the number of stations from an even number
to an odd number or to increase by 2 stations or more]
1) Remove the valve assemblies from all stations. (Remove
from the single units to be added also.)
2) Remove the switch assemblies if there are any. (Be careful
not to drop the O-rings. Refer to .)
3) Remove junction box B (top) from all stations using a precision
screwdriver. (Refer to .) (Remove each junction box B
from the D side.)
4) Remove all connectors mounted to each junction box B. (Be
careful not to break the connector clips.)
5) Remove the tension bolts.
6) Remove the end plate D assembly.
7) Remove the linkage-printed circuit board, and then remove
the connector assembly. (Refer to .)
8) Connect the lead wire assembly. (Refer to .)
9) Remount the connector assembly and linkage-printed circuit
board. (Refer to .)
10) Remove end plate U. (Be careful not to drop the gasket.)
11) Mount the single units for manifold to be added to the end
surface on the U side. (Do not let the gasket get caught.)
12) Mount end plates U and D with tension bolts of the
appropriate length for the number of stations required.
(Tightening torque: 0.75 N·m)
13) Mount the connectors for all stations to each junction box B.
(Refer to .) (Engage the recess of the connector and
the protruding part of junction box B. Refer to .)
14) Mount each junction box B to each junction box A.
Push the wires down and mount each junction box B to each
junction box A starting with the connector station numbers
on the U side. (Refer to .) (Do not let the lead wire get
caught.)
15) Mount the valve assemblies. (Tightening torque: 0.15 N·m)
16) For products with a switch, mount the switch assemblies.
(Be careful not to drop the O-rings. Tightening torque: 0.08
to 0.10 N·m)
