Section 7 Analyzer Commissioning and Startup
The check list below must be used to ensure that the installation has been properly carried out. Please
proceed through the check list in the given order, completing the 5 sections below.
Detailed commissioning
and startup procedures are available in a presentation format in the MMC/SD card shipped with the
BioTector. It is recommended to review this document before starting the commissioning and startup
procedures. If the BioTector analyzer is certified for hazardous areas, carefully read the hazardous area
documentation supplied with the analyzer. This documentation contains important information for compliance
with explosion protection regulations. Understanding this information is essential for the safe operation of the
equipment.
For system and personal safety, refer to Section 1 Safety Precautions . Necessary
safety precautions, such as wearing eye protection and gloves, should be taken throughout the
commissioning and startup procedures.

1. INSPECTION and SYSTEM CONNECTIONS:
FMM20 reagent pumps and reagent tubes are filled with deionized water (DIW), and several other
tubing are disconnected and labeled in the BioTector for shipping. Before connecting any tubing,
inspect the analyzer. Remove the three nuts and open the analysis door. Check all the electrical
and tubing connections and confirm that there are no loose connections within the BioTector.
Close the analysis door.
_____
•
Disconnect the PFA tube at the top of the acid TEE. This PFA tube connects the acid
TEE and the base TEE in a loop. Drain the DIW from the TEE connectors and PFA tube
into a suitable container and dispose. Remove the blank fitting, which is located above
the Reactor Valve, from the TEE connector. Reconnect the free end of the previously
disconnected tube to the TEE where the blank fitting was located.
•
Remove the PFA tubing loop, which connects the acid and base ports, located outside
the BioTector. Drain the DIW from the PFA tubing into a suitable container and dispose.
The nuts and ferrules, located on these ports, will be used for the acid and base
connections.
FMM20 reagent pumps, which have a 50µm particle tolerance, and the
reagent tubing, must be kept free from dust and particulates.
•
Reconnect the tube linking the Ozone Generator to the acid TEE, at the TEE.
•
Reconnect the tube linking the Cooler and CO
2
analyzer, at the top of the Cooler.
_____
The tubing of Sample Pump is disconnected and labeled in BioTector for shipping. Reconnect the
Sample Pump tubing.
_____
Check the Swagelok / PFA tube connections and confirm there are no loose connections within
the BioTector.
_____
Confirm the mains supply voltage and the frequency on site match the analyzer requirements.
Remove the cover of the Power and Input/Output Board by sliding the cover from left to right
slightly. Connect the power cable. Install the supplied ferrite by winding the power cable once
around the ferrite, forming a single loop (see figure 1 and table 2 in Section
4.1.1 Analysis
Enclosure ).
_____
Connect the 4-20mA cables. Install the supplied ferrite on the 4-20mA cables by winding the 4-
20mA cables once around the ferrite, forming a single loop.
_____
Connect low voltage wiring (e.g. Fault Relay). _____
Connect the air supply
to the BioTector’s AIR port. See figure 12 in Section
5.3.1 Air Supply
Connection for details. The minimum air supply flow rate is 8.4 m
3
/hour at 1.5 bar. The average
air consumption is less than 5.4 m
3
/hour, and typically 3.6 m
3
/hour during online operation. When
the oxygen concentrator is running, the pressure typically cycles from 1.5 bar to 0.9 bar.
Option A: Instrument air. The set point pressure of the air, supplied from an existing
instrument air supply line, should be 1.5 bar. The recommended air quality
is -20°C dew point, free of water, oil and dust.
Option B: BioTector Compressor. The set point air pressure supplied from BioTector
compressor should be 1.2 bar.
