Fluids are discussed in detail in Section 8.1.
Remove any access hole cover from the bath and check the tank for foreign
matter (dirt, remnant packing material, etc.). Use clean unpolluted fluid. Care-
fully fill the bath through the large square access hole to a level that will allow
for stirring and thermal expansion. The fluid should never exceed a height of
1/2" below the top of the tank. Carefully monitor the bath fluid level as the bath
temperature rises to prevent overflow or splashing. Remove excess fluid if nec-
essary and with caution if the fluid is hot.
Be careful to prevent bath fluid from spilling on the stirring motor while filling.
CAUTION: Under filling may reduce bath performance and may possibly
damage the bath heater.

Probe

Inspect the bath controller probe. This probe should not be bent or damaged in
any way. Reasonable caution should be used in handling this probe as it con-
tains a precision thermistor sensor. If damaged, the probe can be replaced. Con-
tact an Authorized Service Center for assistance.
Insert the probe into the 1/4 inch probe hole at the top left side of the bath lid.
The tip of the probe must be well immersed in the fluid. The probe connector is
plugged into the rear of the bath into the socket labeled "PROBE".

Power

With the bath power switch off, plug the bath into an AC mains outlet of the
appropriate voltage, frequency, and current capacity. Refer to Section 3.1,
Specifications, for power requirement details. Refer to and read the WARNING
at the front of this manual concerning brownout and over voltage protection.
Be sure the stirring motor power cord is plugged into the "STIRRER" socket at
the back of the bath.
