Unpacking the Orion 7070iX TRO Analyzer
Thermo Scientific™Orion™7070iX Total Residual Oxidant
(TRO) Analyzer is assembled, tested and packaged with
great care.
1. Open the box and remove the accessories boxes from
the top, See “Figure 2 - Unpacking the 7070iX TRO
Analyzer”.
2. The shipping box contains the analyzer, LVD safety
manual, quick start guide and user manual usb drive.
3. Place the analyzer at a suitable location until installation
is completed.

Figure 2 - Unpacking the 7070iX TRO Analyzer
Mounting the 7070iX TRO Analyzer
The Orion 7070iX TRO Analyzer should be installed in a
well ventilated location with ambient temperature between
5 °C and 45 °C (41 ° to 113 °F); and relative humidity must
not exceed 85% at 40 °C (104 °F). The area must be free
from dust, corrosive gases, vibration and shocks; sheltered
from direct sunlight, and shielded from dripping water.
1. Use four #10 screws or equivalent for proper support.
2. Refer to “Figure 3 - Dimension drawing of 7070iX
TRO Analyzer for mounting” for dimensions (in mm
and inches).
3. Make sure that the wall you choose can support the
weight of the instrument. (Approximately 20 kg or 44
lbs.)
4. Locate the instrument as close to the sampling point as
possible to ensure complete purging of the sample line
during each cycle.
5. Allow approximately 610 mm (24”) of clearance on the
left side for door swing. Also, allow enough clearance on
the right side for wiring conduit.
6. Locate the Analyzer height such that the display is at
eye level for an operator, also allowing for appropriate
sample and drain connections.
7. Locate the dedicated external power switch or follow
local regulations for power supply.
CAUTION: The equipment exceeding 40 lbs.
should be lifted with the help of two persons
or follow any heavy lifting policies your
employer has put in place.

Plumbing the 7070iX TRO Analyzer
The sample inlet is on the left of the analyzer. The sample
overflow and waste drain connections are made on the
bottom side of the instrument, See “Figure 5 - Plumbing”
The sample inlet and sample overflow fittings on the
bottom of Analyzer require 1/4" OD (6 mm OD)
flexible tubing. Connect the inlet sample Y strainer to
the 1/4" (6 mm) tube through the adapter provided. The
connection to inlet sample Y-strainer is a 1/2" NPT
(13 mm NPT) pipe thread. The waste drain fitting at the
bottom of the Analyzer requires 3/8" OD (10 mm OD)
flexible tubing.

Wiring Power to the 7070iX TRO Analyzer
Instrument power requirements are 100 to 240 V AC,
50/60 Hz nominal. Wiring of the instrument is the
responsibility of the installer, however, Thermo Fisher
Scientific recommends the following:
• All wiring must be made in compliance with current
national, local electric codes and safety regulations
• Due to a close proximity to water, it is recommended
to use separate power circuit with dedicated Class A
GFCI (Ground Fault Circuit Interrupt) circuit breaker/
disconnecting device, with appropriate voltage and
current ratings
• It is recommended to use shielded power cable, with
3 conductors 18 AWG minimum including ground
conductor. The ground conductor wire free length should
be longer than the AC L (hot) and AC Neutral wires
• The Orion 7070iX Total Residual Oxidant Analyzer ground
connection can be made redundant through double
grounding, either by doubling wires or using mounting
hardware to electrically attach the instrument to
grounded substrate. In case of redundancy provided by
mounting hardware, the primary grounding must be done
with at least a 10 AWG dedicated wire conductor
• Use of a grounded conduit for the power cable is
recommended
• For all wiring details of the instrument and sensors, see
“Figure - 6 TRO Analyzer AC Power Wiring”.

Preparing the 7070iX TRO Analyzer for Operation
1. Take 1 box of 7070iX TRO reagent (7070RE) and pull out
the cover of box tab to uncover the blue cap of reagent
spigot.
2. Pull out the blue cap over spigot.
3. Put the reagent box on the the reagent holder with
spigot facing upright.
4. Push and turn the blue reagent adapter in clockwise
direction onto reagent spigot. Make sure the mark of
adapter matches the spigot and securely locked.
5. Turn the box upside down and make sure reagent label
faces the operator and there is no leakage of reagent.
6. Check if all the plumbing and power supply are correctly
connected.
7. Make sure the 3-way valve is pointing towards the
sample inlet.
8. Power on the 7070iX TRO Analyzer, and slowly turn on
the sample water supply from main pipe.
9. Prime the reagent (if needed). Follow the steps:
a. Press menu
b. Select Measurement
c. Select Prime Reagent
d. Prime will stop automatically after approximately 2 min
e. Repeat the prime step again if air was seen in reagent
tubing.
CAUTION: The analyzer is intended for use
only with single-phase power. The analyzer is
not equipped with a power switch, therefore
a circuit breaking device is required such as
a circuit breaker/disconnecting device. The
circuit breaker must conform to local safety
standards and codes. The circuit breaker
must be fitted before the final installation, prior
to connecting AC power to the Analyzer. The
circuit breaker must be in close proximity to
the analyzer and within reach of the user, and
must be marked clearly as the disconnected
device for the analyzer. ALL CONDUCTORS
NEED TO HAVE MINIMUM INSULATION
RATING OF 75 °C.

Operating the 7070iX TRO Analyzer
NOTE: When operating the Analyzer for the first time, it
is advised to place the system in RUN for 2 hours before
using. This will allow the system to flush any contaminates
out of the system that might have entered during
installation.
Instrument Operation Modes
The setup menu allows you to run the Orion 7070iX Total
Residual Oxidant Analyzer in different modes. There are 4
Instrument Operation Modes are available:
• Continuous mode: The TRO Analyzer will run
continuously and readings on the screen will be updated
every 2 seconds.
• Interval mode: The TRO Analyzer will run at user
defined intervals (from 5 minutes to 30 minutes,
adjustable in 1 minute increments). The reading on
the screen will be updated based on the user defined
interval. The TRO analyzer automatically starts running at
the last two minutes of each interval period, reports
• Remote mode: The TRO Analyzer can be remotely
triggered to start and stop measurement through an
input relay. When the analyzer is remotely started
the analyzer will run continuously and update the
measurement results every 2 seconds until remotely
stopped by the user.
• Scheduled Mode: The TRO analyzer can start
measuring automatically at scheduled starting time and
stop the analysis at scheduled stopping time.
To set the operation mode:
• Select Menu > setup > channel 1 > operating
mode
• If you choose interval mode, you can setup the
interval from 5 minutes to 30 minutes, adjustable in
1 minute increments
• If scheduled mode was chosen, use can setup
“Start/Stop” on screen
