Before connecting any Parr Hydrogenation Appara-
tus to an electrical outlet, the user must be certain
that the electrical outlet has an earth ground con-
nection and that the line, load and other character-
istics of the installation do not exceed the following
limits:

ated from a 50 or 60 Hertz power supply without
affecting the apparatus. The frequency ratings are
identifi ed on the data plate of the instrument.
Current: The total current drawn should not exceed
the rating shown on the data plate by more than 10
percent.
