11) Carefully wash the gyrosphere with alco-
hol and dry it with a lint-free cloth.
Caution:
do not use acetone or similar solvents.
12) Rinse the gyrosphere with fresh support-
ing fluid.
Caution:
The recess of the gyrosphere must be kept
absolutely clean and dry. Do not use com-
pressed air to dry the gyrosphere.
13) Take the box containing the phial of mer-
cury and insulating fluid from the installa-
tion and replacement parts kit. Remove
the phial from the box.
Warning:
Spilt mercury will evaporate and give
off poisonous fumes.
Spilt mercury is to be gathered up with
the syringe provided in the installation and
replacement parts kit and sealed in an
empty phial.
14) Open the phial and pour the entire con-
tents into the recess of the gyrosphere.
The mercury is to form a single drop at
the bottom of the recess.
If necessary, take the syringe and can-
nula from the installation kit and gather
the mercury in a single drop by gently
pressing on it with the tip of the cannula.
15) Close the empty phial and put it back in
its box. The phial is to be kept in the in-
stallation kit and will be needed to take
up used mercury and insulating fluid dur-
ing the removal of the gyrosphere.
