1.0 Overview & Orientation

The AccUView Wastewater process transmission monitor allows for the UV transmission
measurement of process water on-line. The sensor features a low pressure lamp operating
at 254 nm. The unit includes a sampling pump capable of drawing water from 3.6m (12
feet) down. The entire unit is enclosed in a weather resistant stainless steel enclosure.

A unique feature of the instrument is the ultrasonic cleaning. Refer to section 8.1 for more
information.

Remove the instrument from the packing carton. Carefully inspect all items to ensure that
no visible damage has occurred during shipment. If the items received do not match the
order, please immediately contact the local distributor or the HF scientific Customer
Service department.

1.2 The Display

Figure 1 illustrates all the items that can appear on the display. The upper row of the
display (1) is used for reporting the %T levels and to provide user guidance in the
customer setting routine. The lower row of the display (2) is used to communicate error
messages and provide user guidance. All error messages will be added to a queue along
with the units (%T). The display has two icons (3) that are used to indicate the use of
access code and offset mode. In addition, mode arrows (4) are used to indicate the current
instrument operating mode; AUTO (automatic operation), CAL (calibration) and CONFIG
(configurations).

Figure 1 – Display used in the instrument.

All items used on the display are shown in this figure

1.3 The Touch Pad

Figure 2 illustrates the touch pad. The touch pad has four buttons: MODE/EXIT, ↵, t,

and u. The MODE/EXIT button is used to cycle among the four operational modes of

the instrument: CAL, CONFIG, SVC and AUTO (Measurement) mode. The ↵ button
enters the option (or mode that is highlighted or chosen. The tand u buttons are used to

change settings.

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 Replacing or

Installing the Desiccant Pouch.

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.

3.0 Installation and Commissioning

Prior to use for the first time, the supplied desiccant pouch will need to be installed. Refer
to section 9.2 Replacing or Installing the Desiccant Pouch.

3.1 Mounting & Site Selection

The instrument is designed for wall mounting. For rail mounting, contact HF scientific.
Choose a location that is easily accessible for operation and service. Ensure that the front
display rests at eye level. Please note that the enclosure has tool access door, allow ample
room for this door to fully open. The overall mounting dimensions of the instrument are
shown in Figure 4. The recommended mounting screws are M6 (¼”) for the instrument
enclosure.
