Fill the bath tank with an appropriate liquid. For operation at moderate bath
temperatures, clean distilled water works well. Carefully pour the fluid into the
bath tank through the large rectangular access hole above the tank avoiding
spilling any fluid. The fluid must not exceed a height of 3/4 inch below the bottom
of the bath lid.
The control probe must be inserted through the lid into the bath and plugged into
the socket at the back of the bath.
