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.
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:
Several tubing are disconnected and labeled in 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.
_____

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.

Reconnect the fitting linking the Ozone Destructor to the Exhaust Valve (MV1), at the
bottom of the Ozone Destructor.
_____
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 1.5 bar.
In BioTectors built with a vortex cooler, air should be supplied to the vortex cooler using a
regulator, which is dedicated for the vortex cooler only.
_____
Connect the EXHAUST port with ¼” PFA tube to a safe and well ventilated area or to open
atmosphere. The tube must have no restrictions and it must be placed so that any condensation
and liquid buildup in the tubing is prevented. The max
imum length of ¼” PFA tubing installed in
Exhaust line is 10 meters. If tubing longer than 10 meters is required, the use of a larger ID tubing
or pipe is recommended.
The end of the exhaust tubing should have a slight downward slope and should be located in an
environment so that any condensation or liquid at the outlet of the tubing cannot freeze during
cold weather. See figure 16 in Section
5.4.2 Drain and Exhaust Connections for details.
