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 (normal operation), CAL (calibration) and CONFIG
(configuration).
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 between the three operational modes of
the instrument: CAL, CONFIG, 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 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 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
2.0 Safety
This manual contains basic instructions that must be followed during the commissioning,
operation, care and maintenance of the instrument. The safety protection provided by this
equipment may be impaired if it is commissioned and/or used in a manner not described in
this manual. Consequently, all responsible personnel must read this manual prior to
working with this instrument.
In certain instances Notes, or helpful hints, have been highlighted to give further
clarification to the instructions. Refer to the Table of Contents to easily find specific
topics and to learn about unfamiliar terms.

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 ease of service there should be about
20 cm (8”) free area above the instrument; this will ensure enough room for calibration
and cuvette maintenance. Choose a location that is easily accessible for operation and
service and ensure that the front display rests at eye level. The overall mounting
dimensions of the instrument are shown in Figure 3. The recommended mounting screws
are M6 (¼”) for the instrument enclosure and M4 (3/16”) for the field terminal box. The
AccUView is designed to have the field terminal box cradled under the sensor portion of
the instrument. It is recommended that the field terminal box be mounted first, and then
the rest of the instrument be mounted on top. The template included on the last page of
this manual may be used to establish mounting-hole locations.
It is critical that the instrument be mounted as close as possible to the sampling point to
ensure a quick response time (within 2-3 meters (6-10 ft) of the sampling point).

3.2 Plumbing
The recommended plumbing for the instrument is shown in Figure 4. The instrument is
designed to require very little head pressure to operate; around 6.9kPa (1 PSI). Flow
requirements are 100ml/min. – 1 liter/min. (0.026-0.26Gal/min). The integral flow
regulator will limit flow to around 1 liter/min. The pressure regulator will allow for a
maximum pressure of 1380kPa (200 PSI.). The maximum allowable fluid temperature is
50°C (122°F).
Figure 4: Recommended Plumbing for the Instrument
The instrument is equipped to be plumbed using 4.75 mm (3/16”) ID, 8 mm (5/16”) OD
flexible tubing. Opaque tubing should be used if the tubing will be exposed to sunlight, to
prevent algae growth.
In figure 4, there are two operator controlled flow adjustment devices shown. The one on
the input side is a shutoff clamp used during cuvette maintenance. The other device,
located on the output side of the flow cell, is a backpressure valve. Backpressure may be
required to prevent air from coming out of solution, which may be observed as tiny air
bubbles.

3.2.1 Pressurized Systems: A standard feature of the AccUView is a pressure regulator.
The regulator is rated for use up to 1380 kPa (200 PSI) and will lower the pressure down
to a pressure more suitable for use in the AccUView. If inlet pressures can exceed 325 kPa
(47 PSI) use appropriate tubing to connect to the AccUView. The integral flow regulator
will limit the flow to 1 liter per minute.
3.2.2 Drain Vent: The AccUView has been fitted with a drain vent in the “OUT”
bulkhead fitting. This fitting allows for atmospheric equalization, thus helping to alleviate
bubble formation in the cuvette. Refer to Figure 4.
Upon initial flow minor leakage may occur through the drain vent. This will subside once
normal flow is established.
For some high pressure systems, where the vent hole continuously leaks, a 6:32 seal screw
is provided which should be inserted into the vent hole and tightened.
Note: The drain water from this instrument should NEVER be reintroduced back into the
incoming water stream. This water MUST be directed to a convenient drain.
3.3 Electrical Connections
All of the electrical connections to the instrument are made through the field terminal box,
which should be located directly under the sensor portion of the instrument. The
connections are labeled within the terminal box and are self-descriptive (see Figure 5).
Please follow all local and government recommendations and methods for installation of
electrical connections to and between the instrument and other peripheral devices.
Plugs are inserted into the alarm and 4-20mA/RS-485 cable bulkheads when shipped, to
ensure a watertight seal. These plugs should be removed and discarded when cabling to
either of these connections.
The power cable bulkhead will accept cable diameters from 5.8mm (.230 in.) up to 10 mm
(.395 in.). All terminals are designed to accept wires in the range of 14-28 AWG. All
wires should be stripped to a length of 6 mm (¼”). A strain relief strap is provided to
reduce tension on the power terminals.
It is the user’s responsibility to assure that the watertight seal is maintained after the
terminal box has been wired for operation. If any of the bulkheads are not tightened
properly around a cable or plug, the ratings of the instrument will be jeopardized and there
is a possibility of creating a shock hazard.
Note: Only qualified electricians should be allowed to perform the installation of the
instrument as it involves a line voltage that could endanger life.
