8 Gyroshpere Installation and Service
8.1 Safety Notes
Installation and servicing of the gyrosphere include the handling of mercury.
The mercury together with insulating fluid is contained in a glass phial en-
closed in a protective capsule (Sperry stock no. 36026).
If handled according to the instructions given below, at no point during gyro-
sphere installation or service will the mercury come into contact with the open
air. A potential risk of health injury or environmental pollution through evapora-
tion or spillage of mercury can therefore arise only from improper handling.
After installation of the gyrosphere, store the phial in the protective capsule in
the installation and replacement parts kit.
After removal of the gyrosphere or the exchange of mercury and insulating
fluid, seal the used mercury and insulating fluid in the phial and return it to
Sperry Marine for recycling.
