Mount the check valve in the valve block, and tighten with a torque of 40 Nm. Place
the four cylinder pins in the corner holes. Place O-rings in the three holes and
grease. To mount the water pipe, you need a steel bar (HYCON special tool No.
9992079). Insert the steel bar through the steel frame and down in the hole at the
bottom of the frame. Then insert the water pipe over the steel bar and push it into
position. Remove the steel bar. Push the water pipe again to make sure that it is
placed correctly at the bottom of the frame.
