12.3 Assembling the equipment:

In case castor oil had been removed from the oil
chamber:
Pour a fresh quantity of castor oil in up to about
5 mm below the upper edge of the cylinder (at
the beginning of the depression).
Insert both of the silicone seals.
Turn the conical seal inside out and dampen the
stud with some castor oil then screw it into the
guide tube.
Unfold the conical seal back to its original shape,
position the spring on the piston and insert the
guide tube into the piston.
Mount the measuring cell and position it flush
along the edges of the cylinder.
Place the heat casing at the centre of the lower
silicone seal.
Fit the circular grommet and, with the help of a
ruler placed on the heat casing, position it paral-
lel to the cylinder (see Fig. 9, the semicircular
holes should then be below the valve openings).
Fig. 9: Positioning the circular grommet
Place the valve plate at the centre and position it
parallel to the end plate.
Fit the M8×40 screws with new copper gasket
washers and loosely screw them in.
Tighten the screws. Take care to ensure that there
is uniform pressure on the circular grommet (if
the pressure is too high, the grommet makes a
greyish mark on the transparent acrylic, whereas
if the pressure is lower the surface looks milky).
12.4 Recommissioning:
Degas the hydraulic fluid and pour the oil into
the equipment (see chapter 10).
Position the safety valve (see chapter 10).
Conduct a fresh volume calibration (see chap-
ter 6).
