Valve stems pictured may differ from stems packed in kit. Thank you for purchasing Dill TPMS Trailer Kit. Properly inflated tires increase fuel economy, reduce tire wear and increase han- dling. A warning system to notify you of an underinflated tire will help give you time to respond prior to potentially damaging your tire or trailer.

1.0 Setting Up the System 1.1 Transmitter Installation Have a professional tire retailer install the valves with transmitters in the wheels. See section 2 for details. Each transmitter has a unique ID and needs to be installed in the same corresponding position as noted in Figure on page 13.
The display is now in learn mode and will store the cold inflation pres sure of each tire once it receives a signal from it. The process may take up to 8 minutes. If all pressures are not received in 8 minutes, the dis play will shift back to the monitoring mode.

Remove the original antenna from the back of the display unit and replace it with the coaxial wire antenna via display connector. Install the magnet/antenna at the rear of the vehicle, which will give it the nearest proximity to the transmitters. Thus, increasing signal reception between the display/receiver and transmitters.
2.0 Transmitter Installation Before installation into the rim hole, you must assemble the transmitter and valve stem together. 2.1 Unscrew the hex nut and remove the metal washer from the valve stem. 2.2 Place the valve stem onto the transmitter and use the lock washer & screw to hold valve stem against the transmitter body.
2.10 Apply soap suds or commercial leak detection solution on the valve tip, grommet / rim seal. If no leakage is found, install the valve cap. Other wise, re-inspect and resolve leak issue. 2.11 Dynamically balance the wheel before it is put back on the vehicle. FIGURE 5 3.0 System Overview The TPMS trailer kit monitors tire pressure and temperature.

FIGURE 7 The display is preprogramed to provide a warning if the pressure drops 20% below or 30% above the cold inflation pressure. It will also give a high temperature warning if the temperature exceed 176°F. The high temperature warning point is not adjustable. The system is shipped with the baseline (cold inflation) pressure set at 35 psi.
3.3 Normal Monitoring 3.3.1 Stationary State: The transmitter will transmit tire pressure and temperature data to the display at 2-minute intervals. As the data is received, the display will refresh. 3.3.2 Moving State: The inertial switch of transmitter is on when the speed exceeds 16mph.

3.4.3 High Temperature Warning When the temperature in a tire exceeds 176°F, the following will oc- cur: 1. The display will show the temperature of the abnormal tire and the digits will flash. 2. An audible alert warning sound will be heard. 3.

3.7 Tire Rotation Every transmitter has a unique 8 character ID that is associated with a chip in the display. An alpha label is also added to each transmitter and chip as an additional identifier. As tires are moved side to side, the chips are moved to the corresponding position in the display.
