Installation Process
To obtain the benefit of peak performance from the ECO product, it is suggested that you
follow the recommended installation procedure as outlined below:
• Detector Location: Determine the optimum position to place the ECO to maximize its
ability to detect the gas hazard.
•
Physical Installation: Mount the ECO correctly in its selected location.
•
Electrical Installation: Connect the power and other interface wiring.
• Setup Xtralis VSC: Install the free Xtralis VSC configuration software and connect
the PC to ECO USB port. Read and modify the factory default settings, review and
download event logs.
•
Set Date and Time: Set the ECO system date and time to ensure logged events are
correctly time stamped.
• Flow Normalization: Normalize the air flow reading to provide the reference for the flow
fault conditions.
• Gas Sensor Check: Bump test the product using a calibrated sample gas to confirm
proper measurement operation of the gas sensors.
•
System Test: Use the Gas Test function in Xtralis VSC to verify the operation of the
alarms, relays and current outputs.
•
Installation Checklist: Complete and retain the installation checklist.
Air Inlet/Outlet Pipe Connections
The tapered shape of the air inlet/outlet port of the ECO is designed to accept standard
pipes of OD 25mm (ID 21 mm) or BSP ¾ in (OD 1.05 in) and as such provide an air tight
seal without gluing. Connection to pipe networks of other sizes should not be done without
first confirming their compatibility with your Xtralis representative.
Flow Shutoff
Due to the effects of pressure variations across an installation it is recommended that
a suitable shutoff valve is installed immediately before the ECO in the pipe work, i.e.
on the sample inlet side. This will help to prevent ambient pressure differentials caused
by aggressive air conditioning from generating sample flow through the ECO during
calibration when the aspirator is shut off.
During calibration or bump testing no air flow should pass through the ECO detector. The
shut off isolation valve will provide a simple means of accomplishing this.
Notes:
Do not install your ECO detector if there are any signs of shipping damage.
Inform your distributor if there is any visible damage.
Check that the model of the ECO detector is correct as per the design
specifications of the site. Refer to the model number located on the main
product label and ensure that the gas types and ranges are of the correct
specification.
When using VESDA ECO with the VESDA VFT-15 or ICAM IFT-15 detectors a
special adapter is required, part number ECO-FT15.
Installation Instructions
To fix the detector to the pipe work, follow these steps:
1.
Ensure that any glue used in fixing the sample pipes has been given sufficient time to
cure such that any vapours from the glue will not affect the gas detection before fitting
the ECO detector.
2. Remove a straight section from the pipe at the preferred location within the pipe work.
The exact length of pipe to be removed depends on the tolerances of the pipe-work
being used, but as a guide the lengths are approximately:
•
60 mm when installing in a 25 mm OD pipe
• 4 inches (100 mm) when installing in a ¾” BSP pipe
3. Ensure that the cuts on the pipe are perpendicular to the pipe and that there are no
burrs or sharp edges present. If so, trim the pipe to remove them. Ensure the pipe is
free of any debris.
4.
Verify the correct orientation of the ECO detector, in that the flow arrow on the side of
the ECO enclosure is in the same direction as the sample airflow.
5. Insert the detector into the open section of the pipe, ensuring that the pipe entry to the
detector is square and the pipes sit correctly in the tapered air inlet/outlet ports and
provide an air tight seal.
Note:
Do not glue the pipes to the detector. This is not necessary and is an obstacle
to future maintenance.
If the gas test port is not to be permanently connected to a remote gassing
pipe, ensure that the blanking plug supplied with the unit is fitted firmly in place.
Alternatively, if a permanent remote gassing pipe is to be installed, use 6 mm
OD pipe fitted into the gas test port of the ECO at one end and ensure the
opposite end is fitted with a gas tight plug during normal operation.
6. Ensure that the device is oriented such that the status indicators are visible for
inspection purposes.
7.
Ensure that there is sufficient access to the enclosure cover such that it can be
removed and the sensor cartridge accessed.
8.
During calibration no flow should pass through the ECO detector. Installing a shut
off isolation valve in front of the ECO detector and shutting the aspirator off during
calibration will help achieve this result. Ensure that the valve does not restrict the inside
diameter of the sample pipe. Installing a clean out tee in front of the valve to facilitate
routine pipe network cleaning, without having to remove the ECO detector or pipe is
also recommended.
