Agilent 708-DS Dissolution Apparatus
Training Manual
Revision A September 2010
P/N: xx-xxxx
2.1.2. Heater / Circulator Setup
The 708-DS utilizes a water bath to heat and maintain temperature within
the dissolution vessels. The water in the bath is heated and circulated by
a Heater / Circulator (H/C) that is positioned behind the water bath. The
H/C should be installed beneath the back of the vessel plate with the
power outlet facing the rear and legs inserted into the holes of the base
plate.
Figure 2-1. 708-DS Heater / Circulator
NOTE: To prevent damage to the heating elements, the unit should not be powered ON
until the all tubing connections have been verified and the bath has been filled with water.
2.1.3. Communication / Power Cord Installation
Before turning the apparatus ON, the communication cables and power
cords are installed. The 708-DS and its’ accompanying H/C each have a
power cord requiring connection to an outlet of the appropriate voltage.
The H/C communication cable is a 6-pin cable that connects the H/C to
the position marked BATH HEATER on the rear of the apparatus. Also,
the Bath Temperature probe is connected to the BATH TEMP port on the
rear of the 708-DS and the probe is inserted into the hole in the center of
the vessel plate (between the back middle vessel positions).
A unit not equipped with AutoTemp may include an additional External
Vessel Temperature (EVT) Probe. This probe is inserted into the VESSEL
TEMP jack on the rear of the apparatus drive unit. The other end of the
probe is placed in the hole in the left side of the vessel plate toward the
back.
