Be sure to read before handling.
Refer to pages 29 through 32 for safety instructions and common precautions.

are safe prior to activation.
The non-locking push type (tool required) is
standard, and the slotted locking type (tool required)
is optional.

After confirming that the gasket is installed
correctly, securely tighten the mounting screws
according to the tightening torque shown
below.
1. Loosen the clamp screws until they turn freely. (The screws do
not come out.)
2. Remove the solenoid valve from clamp B by lifting the coil side
of the valve while pushing on the screw top.
If pushing down on the screw is difficult, you can alternately
press down on the valve gently in the area near the manual
override.
1. Push the clamp screws. Clamp A opens. Now insert the end
plate hook of the valve into clamp B from an angle.
2. Push the valve down into place. (When you release the screws,
the valve will be locked into clamp A.)
3. Tighten the clamp screws with a tightening torque of 0.25 to
0.35N⋅m for VQC1000 and 0.5 to 0.7N⋅m for VQC2000.
Do not let foreign matter stick on the seal side of the gasket and
solenoid, as this will cause air leakage.
