Replacement of cylinder port fittings
The cylinder port fittings are of a cassette type for easy replacement
(except for VQ0000). The fittings are blocked by a clip inserted from
the top of the valve. Remove the clip with a screwdriver to remove fit-
tings. To replace, insert the fitting assembly until it strikes against the
inside wall and then re-insert the clip to the specified position.
Disconnection
Push down on the collet flange, hold down, and withdraw the tube.

Lamp and surge voltage suppressor (Fig 7)
All solenoid valves are equipped with lamp and surge protection as a
standard feature. The indicators are positioned on one end of the
valve, for both single and double solenoid types. The colours of the
indicator lamps match the colours of the manual override buttons.

Removal of a Valve (Fig 5b)
1. Disconnect electrical connector. (See above.)
2. Slacken lower tie bolt 2~3 turns. Remove the upper tie bolt
and retain. Separate the valves either side of the valve to be
removed approximately 2mm. Lift the valve to be changed off the
manifold, in the direction of the arrow .
Replacing a valve (Fig 5b)
Reverse the above procedure to replace a valve.
