Tank AlertUltrasonic Liquid Level MonitorInstallation InstructionsTankAlert monitors and displays liquid levels and gives an alert when the level drops below 5% of tank height. There are 2 product types (1) Transmitter (no display - 2 versions as in diagrams above) + Receiver and (2) Transmitter with Visual display (allows user to view liquid level at tank) + Receiver; please follow the installation instructions for the correct type.Fuel & Tank Types Preparing the Tank1a) To avoid error, the TankAlert transmitter must sit in a vertical position on top of the tank and have a direct line of sight to the liquid level in the tank, through to the bottom without any interference from e.g. window configurations or tank braces.b) Install the supplied metal adapter into the pre-drilled 2” NPT opening on the top of the tank. Apply pipe sealant on the adapter thread and tighten appropriately. For basement tanks, temporarily place a rag/cover over the adapter to minimize fuel odors until transmitter is synchronized. Tanks with 1½” and 1¼” NPT openings or European style double-wall tanks require adapters. Do not use an extension pipe when mounting the adapter; this can cause inaccurate measurement and malfunction. c) Installation Help: Avoid tank braces and tank windows.Setting the Switches onthe Receiver3Activate the switch (located at back of receiver) numbers that correlate to your tank size (see chart at Step 9 overleaf) by using a screwdriver or ballpoint pen to move the switches upwards to the ON position. Activating switch 1 (the audible ring feature), enables a bleep to indicate a low-level reading (< 5% liquid warning). Matching Receiver and Transmitter for both visual and no-display types.4You can now link/match the receiver to the transmitter, through getting a unique code for your tank (this need only be done once, at installation). • Plug receiver into a convenient electrical socket and switch on.• The display screen on the front of the receiver will show a flashing top bar as shown in diagram (opposite) for up to 2 minutes indicating that the transmitter can be matched to the receiver during this time. • Hold the transmitter (left side) against the receiver’s right side so that the black dots on each are aligned (for 20 seconds). This allows the unique code to be transferred. During the matching process, you will hear an audible beep from the receiver to indicate matching is in progress. The number of bars will increase on the receiver display until all 10 bars are flashing and an audible beep occurs: this indicates that the unique code has been transferred. The setup is now complete for the no-display type only; the transmitter is now ready to read and transmit liquid levels and must be placed on the tank immediately (Step 6).• If matching visual (LCD display) transmitter, you MUST continue to hold the two units together and proceed to the next stage of the matching process (Step 5 across).Additional Matching Step To Calibrate Visual Transmitter to Tank Height(TankAlert Visual ONLY)5When using TankAlert Visual, the visual transmitter must also be calibrated to the tank dimensions. so that liquid levels can be read at the tank as well as in your home.To do this, you MUST continue to hold the transmitter and receiver together (via the black dots) after the ten bars are showing on the receiver (post Step 4). Continue to hold the black dots together until the visual transmitter screen goes blank. A nozzle icon will flash in 10 seconds, indicating that the transmitter is in ‘tank height setting’ mode. Continue to hold as the black bars increase until the number of black bars, according to the table below, increases to match the height of the tank measured at step 2.When the number of bars indicates the correct tank height, immediately separate the transmitter and the receiver.Define Tank Height2Accurately measure the height of your tank from the liquid outlet at the bottom of your tank to the bottom of the TankAlert ultrasonic monitor. TankAlert measures the level of usable liquid in the tank in 10 graduations of the tank height. Correct tank height measurement is critical for accurate liquid level display.Wait for a double flash of the red light on the visual transmitter to indicate that the tank height setting has been stored in the transmitter. The transmitter can now be placed on the tank.There may be one bar more or less displayed on the visual transmitter display compared to the receiver display when operational. This is due to the smaller number of tank height settings that may be selected with the transmitter screen bars compared with the receiver switches. The bars in both displays will accurately reflect the level in the tank. Note: if the number of bars displayed overruns the height setting table (below), continue to hold the black dots together until the screen returns to blank and the nozzle flashes; re-start the process again until the correct number of bars appear. 7 7 73Tank Height(Inches/mm)31/800 39/1000 43/1100 47/1200 51/1300 55/1400 67/1700 79/2000 91/2300 102/2600102/2600 to 116/3000Contents of PackA ReceiverB Transmitter (Visual or no display)C Mounting AdapterD ScrewsE Weather SealACD EBPosition Tank ona Level Surface Fill PointBottom of Tank1000mmTankAlert can be used on all standard steel tanks.

Power Failure or Receiver Moved In the event of a power failure or the receiver being switched off, the receiver display screen will show a top bar flashing for 2 minutes when power is restored. The screen will then turn blank until the unique signal is located (there is no need to repeat the ‘black dot’ matching instruction). This could take up to 1 hour.Troubleshooting8The 10-level bar graph represents the level of liquid in your tank. The number of bars illuminated denotes the level of liquid in the tank. You will get 2 re-fill warnings as shown in the diagrams below. (a) Full: Note: It may take 1 hour to get the first accurate reading post installation. (b) Early Warning (2-bars): (c) Almost Empty (1-bar). Fitting Transmitter6For tanks with pre-drilled 32mm hole:• Remove cap from pre-drilled hole and insert transmitter, ensuring the weather seal is securely in place and that transmitter sits vertically.• Tighten on to the tank with 2 stainless steel self-tapping screws provided. Do not use longer screws or over tighten.For tanks with a 2”, 1½” or 1¼” BSP/NPT gauge aperture (60mm/48mm/42mm)• Unscrew any caps from hole; fit adapter provided by screwing into gauge socket.• Fit TankAlert to adapter on the tank; ensure weather seal is in place.• Tighten on the tank using the screws supplied. Do not over tighten. NOTE: Mounting Adapter supplied must only be used.tekelekgroup.comFullEarly WarningAlmost Emptyb. No Transmission Signal Flashing triangle, no bars, indicates no signal being received. This starts approximately 12 hours from the last received good signal. Re-site the receiver closer to the transmitter and wait for a few hours.c. No Ultrasonic Echo Flashing triangle, middle bar only. Check that the transmitter is fitted vertically on tank, with no interference from a tank wall, corrugation or window. If matching is not completed in the 2-minute interval on plugging in the receiver for the first time – then turn off the receiver at the power point and then turn it on again to initiate a new matching interval.d. Low Battery Signal: Constantly Flashing Warning Light. 1. Remove transmitter from the tank and take it into a clean, dry environment. 2. The battery can be accessed by removing 4 self-tapping screws from the base of the unit. 3. Remove the old battery noting the orientation (+ mark facing upwards) and replace with a new battery (3V-CR2450) 4. Re-assemble, ensuring the O-Ring is undamaged and secured in position. 5. Place the transmitter on the tank. No need to re-match.
