Page 4: General Information
1. GENERAL INFORMATION 1.1 Use of the Manual This manual covers installation of the nVent RAYCHEM TraceTek Fast Fuel Sensor (FFS) for hydrocarbon fuel leak detection in commercial and industrial applications. The manual covers general area preparation and sensor installation, wiring details, testing and periodic maintenance for the FFS only. -
Page 5: Storage
1.2 Storage • Store the FFS in a clean dry place in its shipping box until ready for installation. • Storage temperatures may not exceed –40°C (–40°F) to 85°C (185°F). • Protect the FFS from mechanical damage. 1.3 Safety Guidelines The safety and reliability of any fuel leak monitoring system depends on the quality of the products selected and the manner in which they are installed and maintained. -

– 250 mm version, 1 ft, 3 ft or 10 ft lead, with or without a metal connector • nVent RAYCHEM TraceTek Probe Tester – To confirm FFS functionality before installation. • Probe Tester Operating Instructions (H58496) •... - Page 7 If the Probe Tester indicates the FFS is in alarm, clean the FFS with Isopropyl Alcohol according to the Care and Cleaning Instructions (H58307). Once the FFS has been cleaned, retest it with the Probe Tester to ensure it is operational. If the FFS does not reset after this procedure, contact your local nVent representative to obtain a replacement unit.

Page 8: General Installation Instructions
3. GENERAL INSTALLATION INSTRUCTIONS 3.1 Installation Orientation The FFS is designed to be mounted upright with the leader cable coming out of the top. This positions the sensor as close to the floor or fuel location as possible and minimizes the amount of fuel required to trigger an alarm. - Page 9 water and the water level may vary due to rain or other sources. The longer 250 mm sensor length will remain effective for larger variations in water level than the 100 mm device. 3.9" (100 mm) 1.0" Active region (25 mm) 5.7"...

Page 10: Positioning The Ffs
• End termination options include a water tight connector compatible with other nVent RAYCHEM TraceTek cables or simple pig-tailed leads. The connectors have the advantage of straightforward connection in the field and a water- sealed interface when assembled in accordance with the manufacturer’s recommendations. -
Page 11: Application Specific Installation Instructions
The FFS body should be secured to the mounting bracket via zip ties or some other removable retention mechanism. It may be desirable to move the FFS out of the way during equipment maintenance, either to protect it from damage or prevent a false alarm due to fuel spilled during maintenance activities. - Page 12 • If the diesel generator is not recessed, then it is recommended that a weir be constructed around the generator to contain any leaked fuel. The FFS should then be mounted within the weir to ensure contact with any leaked fuel.

Page 13: Fuel Filters And Valves
4.2 Fuel Filters and Valves Fuel Filters, Valves and other points at which pipes interface or connect represent the highest probability of becoming a leak point. A weir should be built around the potential leak point or equipment to contain any leaked fuel. •... -
Page 14: Fuel Storage Tank Overflow Protection
Warning: The FFS can be damaged if immersed in water and the water freezes. The sensor must be removed from the water prior to freezing (i.e. by draining the area or moving the sensor) or heating measures must be taken to prevent the water from freezing. - Page 15 Warning: The FFS can be damaged if immersed in water and the water freezes. The sensor must be removed from the water prior to freezing (i.e. by draining the area or moving the sensor) or heating measures must be taken to prevent the water from freezing.

Page 16: High Dirt And Wind Environments
4.5 High Dirt and Wind Environments For applications in which the FFS is subjected to high winds and potentially abrasive materials like sand, the Extreme Environmental Cover is recommended. The cover blocks blown dust and debris from abrasively damaging the Fuel Sensor material but allows leaked fuel to flow up from the bottom and through the holes in the cover to reach the sensor. -
Page 17: Commissioning Section
Environmental Cover (EEC) onto the FFS are provided in the EEC Installation Instructions (H58519). 5. COMMISSIONING SECTION Once installed, both the FFS and the nVent RAYCHEM TraceTek Leak Detection System should be tested to confirm an alarm will be generated at the point of user interface. - Page 18 5.1.1 Functional Testing – FFS in System Where possible, functional testing of the FFS with it connected in the full nVent RAYCHEM TraceTek system is preferred as this will validate functionality of the system in addition to that of the FFS.
- Page 19 a. TS12 – Audible alarm will sound and the appropriate circuit listing on the touch screen display will turn red. b. TTDM-128 – Audible alarm will sound, the Leak LED on the front panel will light and a leak notification will be displayed on the LCD text display for the appropriate circuit.
- Page 20 b. If applicable, verify that no alarms exist at the master controller (TS12 or TTDM-128). c. If applicable, verify that any third party systems are not indicating an alarm. 2. Remove the FFS from its mounting bracket and unscrew the metal connector. It will be necessary to remove the shrink tube seal which should have been applied over the connectors.

RAYCHEM TraceTek controller, connect the FFS to the controller, and follow steps 1) through 8) shown on pages 18-19 Section 5.1.1. 2. Connect the FFS to the Probe Tester. a. If the LEDs on the Probe Tester do not flash, proceed to Step 3. -
Page 22: Cleaning
6.1 Cleaning Cleaning Instructions for the FFS are provided in the FFS Care and Cleaning Instructions (H58307). This process is used during both maintenance and to reset the FFS if it has been in contact with hydrocarbons from a real leak. 6.2 Functional Testing Functional testing may be performed with the FFS in place or separately using the Probe Tester. - Page 23 To functionally test the FFS with the Probe Tester, use the following procedure: 1. Remove the FFS from its mounting bracket and unscrew the metal connector. It will be necessary to remove the shrink tube seal which should have been applied over the connectors.
