HF scientific AccUView Wastewater UV %Transmission Monitor - Manual (Page 10)

1.4 Vapor Purge
The AccUView Wastewater sensor is equipped with a continuous vapor purge system. A
replaceable desiccant pouch in the lower portion of the instrument dries the air. System
heat is used to warm the air. A fan inside the instrument continuously circulates heated dry
air around the optical well and the flow through cuvette. This feature eliminates the need
for a dry purge line.
The AccUView Wastewater Sensor monitors the replaceable desiccant pouch condition
continuously. The LCD display will show
DESC on the lower line in the event that the
desiccant pouch needs replacement. Replacement desiccant pouches are available from HF
scientific or the local representative (Part # 21555R). Refer to section 9.2

1.5 The AccUView Wastewater Panel
All of the main components of the system are mounted on a panel inside the stainless steel
enclosure. There is easy access to all serviceable parts. Please note that all terminations
are within separate enclosures. This modular approach enables replacement or service of a
single module without need to return the entire system. Figure 3 shows all the modules.
