WARNING
Ensure all air and power supplies are ISOLATED before commencing
installation.
Do not install these valves in explosive atmospheres.
If these valves are exposed to water or oil droplets, ensure that they
are protected.

Connection/Disconnection of socket to connector (Fig 3)
Connection
Insert a socket complete with lead attached into square hole (marked
+, -) of connector. Push firmly until hook engages. Confirm engage-
ment by lightly pulling the lead.
Disconnection
To disconnect socket and lead assembly from the connector insert a
pin of approximately 1mm diameter into the hole in the connector,
located on the opposite side to the lever. Depress the hook on the
socket and withdraw. If the socket is to be re-used, gently spread the
hook of the socket.

However, if a lubricant is to be used with a rubber seal type, a turbine
oil type #1, (ISO VG32) should be used. Continuous lubrication must
be carried out as the original lubricant will be washed away.

WARNING
(plus) and (minus)
Exercise EXTREME CAUTION when operating a solenoid manual over-
ride as connected equipment will commence operation.
Ensure all safety measures are in place.
Non-locking push type (Fig 8)
1. Push down the manual override button (Orange), until it stops,
using a small-bladed screwdriver.
2. Hold this position for the duration of the check (ON position).
3. Release the button and the override will re-set to the OFF
position.
Slotted locking type (Fig 8)
To lock
1. Insert a small-bladed screwdriver into the slot and push the man-
ual override down until it stops.
2. Turn the override through 90° in the direction of the arrow (ON
position).
3. Remove screwdriver.

WARNING
In this position the manual override is in the locked "ON" position.
To unlock
1. Insert small-bladed screwdriver into the slot of the manual
override.
2. Turn the screwdriver 90° in the reverse direction.
3. Remove the screwdriver, the manual override will re-set to the
"OFF" position.
Piping (Fig 9)
1. Ensure that the pipe is clean of swarf, cutting oil, dust etc.
2. When screwing the pipe of fitting into a port ensure that any
sealant is prevented from entering the valve. When using sealing
tape leave the first 1.5~2 threads free of tape.

Tightening thread portion
When installing fittings etc., tighten thread portion as follows:
1) M3, M5
1 In the case that you use SMC fittings etc., please tighten thread
as follows: First tighten it by hand, then give it an additional 1/4
turn for M3, 1/6 turn for M5 with a wrench. And in the case of
minutia fittings, tighten it by hand, then give it an additional 1/4
turn with wrench. Also universal elbow and universal tee which
have gaskets at two points, give it an additional 1/2 turn with the
Pilot valve
wrench. Note: Excessive tightening may damage the thread por-
tion or deform the gasket to cause air leakage. Also insufficient
tightening may have the thread loosened or cause air leakage.
2 In the case that you use fittings except SMC, please confirm the
instruction by that company.
