Monitor Components & Icons
This EEZ RV PRDUCTS EezTire E518 Tire Pressure and Temperature Monitoring System (TPMS) is a heavy-
duty versatile system designed to operate on a variety of vehicles. (i.e. Motor Coach, 5th Wheel, Travel
Trailer, Auto, Trailer, Big Rig, Farm and Mining Equipment).
SYSTEM OVERVIEW
The system comes with a monitor that can handle 26 wheels with pressures up to 210 psi. The sensors
are lightweight and do not affect the tire balance and have easy to change replaceable cr1632 batteries.
The system offers a method of dropping either the towing vehicle or the towed vehicle separately. This
allows you to monitor the towing vehicle without a towed or the towed when driving away from the
towing vehicle.
The monitor scrolls automatically through each wheel measuring tire pressure and temperature,
displaying it on the monitor. Alarms can be preset by the operator so visible and audible alarms can
warn the driver of a catastrophic failure (rapid air pressure loss), high or low pressures and high
temperature. The alarms and monitoring are sent wirelessly in real time to the cab allowing the
operator to monitor tires that are out of their vision. The audible alarm eliminates the need to watch
the monitor continually.
Tire Pressure can be displayed in PSI or Bar and temperature in Fahrenheit (F) or Celsius (C). Pressure
alerts can be set to a different pressure setting for each axle, so additional towed trailers or vehicles are
no problem. An optional booster can be purchased from your dealer or at www.eezrvproducts.com if
you have signal loss due to distance, structural or electronic interference.

6
The monitor has a rechargeable Lithium Ion battery. Sensors come with either the Anti-Theft security
feature or Flow-Through feature, and the monitor comes with both an auxiliary charger and a hard wire
cable at no extra charge.
The EEZ RV PRODUCTS Eez Tire E518 TPMS System offers both easy installation and one of the largest
LCD monitors on the market.
GENERAL INFORMATION
A tire professional or your owner’s manual should be used to determine the proper tire pressure for
your vehicle. Recommended operating tire pressures should be set when the ambient temperature is
low or cold.
Dramatic changes in tire pressure can occur because of; increased or decreased ambient temperature,
tire contact surface temperature, wheel and axle loads, sun shining on a side, etc. These and other
conditions should be taken into consideration when setting initial tire operating pressures.
This system cannot warn you of side wall failures; however, it can
supply you with irregular pressures and temperature information that may help to prevent this. If the
monitor is shut off overnight simply switch the monitor back on before departure and your real-time tire
pressures and temperatures will be updated and typically appear on the screen within 5 to 10 minutes.
Even if the monitor is in the sleep mode the system is always monitoring and will alarm should any
pressure settings or temperatures be out of your set parameters.
The Schrader Valve (core - inside the valve stem) should be the correct size, be in good condition and be
able to be depressed fully to allow the release of air to the sensor so it can operate. Some valve stem
extensions may cause inaccurate readings if they do not enable the sensor to work correctly, metal
bodied stems, or T-Valve type is recommended for best performance. Should you have difficulty with a
pressure sensor not working properly, we recommend that you contact a tire professional to ensure that
the tire stem and Schrader Valve are installed and operating properly. If using internal tire sealants or
balancing compounds/beads check with the manufacturer to ensure they are compatible with TPMS
systems or that you have filtered valve cores installed. Over a period, tires may lose pressure naturally,
through the tire itself or for other reasons such as rim leakage, etc. After installing the sensors on a tire
valve stem, it is recommended to perform a soapy water test using 1/4 dish soap and 3/4 water. Spray
the soapy solution on the valve stem and sensor area to ensure the sensor is seated all the way. If air
bubbles are seen in any of these areas, the tire may deflate. The wheel sensors are weatherproof and
can be run in the rain.
Consulted a tire professional if any of these areas prove to be a problem.
Purchasers of this product should not solely rely on this tire pressure monitoring system for safety and
should check the condition and pressure of their vehicle’s tires on a regular basis as described by the
manufacturer of the vehicle or tire manufacturer. Please note, the EEZ RV PRODUCTS EezTire T515/ SP
TPMS System operates on an RF system, as with many RF tire systems this system can occasionally suffer
from interference depending on the location of the system; thus, causing the system to be inaccurate or
not operate at all. Tire pressures and temperatures are not the only things that can affect tire safety; we
suggest daily visual inspections and periodic checks by tire professionals.

SYSTEM SETUP
This portion is designed to make the set-up of your new EEZ RV PRODUCTS
EezTire E518 TPMS System easier and faster.
Much of the information contained in this manual is found through real life
experience using the system and passed on to hopefully make the utilization
of the system easier for you.
Please read through the guide thoroughly before starting. Complete set-up
should take approximately 20 minutes.
EEZ RV PRODUCTS EezTire E518 SYSTEM
START YOUR SET UP HERE - Step by Step Instructions:
1. Unpack all the components of your TPMS System and ensure it is
complete.
2. Take the number kit from the accessory pack and number all your
sensors as indicated below. (Hint: After affixing the number to the

8
sensor take some clear nail polish and paint over the number. This will
help ensure it stays on in inclement weather conditions.)
3. On the diagram on the last page of this manual assign the
numbered sensors to each tire as they will be put on your rig and
tow vehicle. Also fill in the tire pressures for each axel.
4. Program the alarm parameters using STEP 1 setting your system
alarm parameters.
5. Program each sensor to the monitor using STEP 2 programing
sensors to the monitor.
STEP 1: SETTING YOUR SYSTEMS ALARM
PARAMETERS
Refer to the diagram on the last page of this manual where you wrote
the “HIGH and LOW” pressure for each axel.
1. Next to each axle write down what your tire pressure is by axle and
calculate what your alarm setting will be.
2. High-Pressure setting will be (20% above axle tire pressure).
3. Low-Pressure setting will be (10% below axle tire pressure).

9
Example: Front Axle Tire Pressure is: 100 psi High-Pressure Alarm
Setting will be: 120 psi (100 psi x 1.20 (or 20%) = 120 Low-Pressure
Alarm Setting will be: 90 psi (100 psi x .9 (or 90%) = 90
These are industry standards for the initial set-up. Some adjustment
may be needed on your first trip.
For the temperature, it is recommended leaving it at the factory
default of 158 degrees F.
STEP 2: Choosing Pressure and Temperature
Unit of Measure:
PRESS and HOLD the SET button for 3 seconds until you hear the
beep. You will see PSI flashing on the left side of the screen. Press the
set button again and you can change to BAR by pressing the + or –key
to scroll between the two. When the one you want to use appears in
the screen press and release the SET button. (Pressing and releasing
the SET button in this mode is like saying yes to what the screen is
showing you)
Press the set button again and “F” will be flashing. Press + or –to
change to “c” if you like. The next time that you press the set button
the front axle will be flashing and the words “HIGH PRESSURE”will be
displayed. Follow the instructions below.
STEP 3: Choosing per Axel High and Low
Parameters:

10
Using the set key scroll to your first axel “HIGH’ pressure. Use the plus
or minus to set your HIGH PRESSURE. When you reach your desired
pressure press and release the “SET’ button again and ‘LOW
PRESSURE’ will be displayed. Use the plus or minus keys to set your
low pressure. Press the set button again and the next axel will flash
“HIGH PRESSURE”. Make your adjustments the same way as for the
first axel. Skip any axels that you are not using and just keep hitting
the “SET” button until you get to the axel that you want to set.
When you have finished setting your parameters PRESS and HOLD the
SET button until the monitor beeps and you are back to display mode.
Keep in mind that the monitor will time out in 40 seconds. So, wright
down your settings before you start.
PROGRAMMING SENSORS TO THE MONITOR
METHOD 1 tabletop (this is the easiest way)
1. Using the switch on the left side center of the monitor, push it up to
turn on the monitor. Place the monitor flat on the table in front of
you. Then place your numbered sensors on the table about a foot
away from the monitor.
2. Press and hold the CODE button on the lower right side down for 3
seconds until you hear the beep. At this time, you will see all 26 tires
on the monitor screen, and the right front tire will be flashing. After
programing only, those tires that you program will show on the
monitor. That is tire number 1. Following your diagram on the back of
your Manuel, place the first sensor on the table and push it against
the base of the monitor next to the set button. You will see “FFF FFF”
on the screen. All F's means that that sensor is not programmed yet.
Then press and release the code button one time. The monitor will

11
beep, and a random code will be displayed. Press the plus button to
go to the next tire and do the same and so on.
3. When you have programed the last sensor, press the “CODE”
button down until the monitor sets off the alarm. Then turn off the
monitor then turn it on again to make sure the tires are programed in
the right position.
4. Install your sensors to the valve stems in the order that you
programed them. Give the monitor 5 to 10 minutes to register all the
sensors. Once the sensors are synced you will not have to re-sync
unless you turn off the monitor. You can leave the monitor turned on
by the monitor’s battery power. The monitors internal battery will run
for 60 hours between charges.
NOTE:
If you get an ID LF (low frequency), error code, hit the sensor hard on
the table to wake it up and repeat. If you still get the Id LF repeat,
press the CODE button and release, pause and then press the CODE
button and release again. If it still gives ID LF then check the battery
voltage with a volt meter. The voltage on a fresh battery should be
3.2v. If it is at or below 2.8v replace the battery with a fresh one.
Method 2: AIR ACTIVATION (Most Difficult)
1. Using the switch on the left side center of the monitor push it up
to turn on the monitor.
2. Place the sensors on the tires as numbered on your diagram but
not under air pressure yet.

12
4. Press and hold the “CODE” button on the lower right side down for
3 seconds until you hear the beep. At this time, you will see all 26 tires
on the monitor screen and the right front (#1 passenger side) tire
should be flashing.
Place the monitor within 3 inches of the sensor and screw the sensor
all the way on. Wait a few seconds and the monitor will beep and a
random code will be displayed. If it does not press and release the
“CODE” once. Once coded press the plus button to go to the next tire
(#2 drivers’ side) and repeat the steps. Use the plus key to go to the
next tire and repeat, skipping any tire that is not on your rig.
YOUR SYSTEM IS NOW SET-UP AND READY
FOR USE
If you have problems, see trouble shooting starting on page 27.
MONITOR DISPLAY IN OPERATING MODE:
After the sensors have all been programmed and the system is in
operating mode the display will automatically scroll through each
monitored tire one by one. The tire being transmitted will flash on the
screen, and the pressure and temperature for that wheel will be
displayed on the monitor. When the monitor is initially turned on it
may take up to 5 to 10 minutes for the monitor and sensors to sync up
before the pressure and temperature will show up on the monitor.
Wait for all the tires to read before driving
After this time if you see one sensor is still not transmitting the
pressure and temperature you may want to delete the sensor from
the monitor and reprogram. On an initial set up, if the tire still fails to

13
indicate a pressure and temperature remove the sensor and back the
Schrader Valve (valve core) out approximately 1/8 to 1/4 turn and
reinstall the sensor. This will ensure there is sufficient contact and air
pressure to the sensor.
NOTES and RECOMMENDATIONS:
There will be an audible single “chirp,” and the tire will flash if the
monitor has not received a reading from that tire after 30 minutes. If
you are still receiving PSI and Temp readings from the sensors, then
the chirp is an indication of low battery on that sensor. You can also
manually scroll through the tires one by one by pressing the + or -
button. If you manually select a tire the monitor will show its readings
for 10 seconds. The monitor comes equipped with a light sensor; the
backlight will typically come on if the vehicle is in motion and the light
level is low enough. You may also wave your hand in front of the
monitor to manually activate the backlight or by pressing any button.
It can be turned off by pressing the + button for 3 seconds. The light
sensor is located on the lower left of the monitor, just left of the
“LINK” button. The monitor comes with a built-in motion sensor; it
will go to sleep (energy saver mode) if there is no movement of the
vehicle detected for approximately 15 minutes and wake up when it
detects movement. It is recommended that the monitor is shut off
when the system is not in use, or you are staying in the vehicle
overnight. When external power is applied to the monitor it will
override the manual on/off switch on the left side. If you hard wire
your system charger to a “keyed” switch the system will go off when
the keyed power is turned off. If you are using the auxiliary charging
cord, you will have to unplug the charger manually. You will get a
longer service life from your monitor’s internal battery, if you

14
disconnect the external power source and allow the battery to
deplete through normal operations every couple weeks naturally.
Factory Defaults
The factory default settings are as follows:
High Pressure (175 PSI),
Low Pressure (35 PSI),
Temperature (158 degrees).
RESTORE PARAMETERS to FACTORY
DEFAULTS:
Turn off the monitor; press the SET button and activate the monitor at
the same time. The RED light will flash, and factory settings will be
restored.
Pressure Unit: PSI High Pressure: 175 psi (12.1 BAR) Low Pressure: 100

MONITOR INSTALLATION
Your system comes with three mounting options: a plastic tower with
suction cup mount for window or dash, low profile mount for dash,
low profile triangle mount for dash. Some people prefer to use
Velcro or the small bean bags used

15
for cell phones on their dash.
1. mount it onto the windscreen or left side window using the
suction cup provided ensuring you do not obstruct the driver’s vision
of the road. 2. Plug the power adapter into the cigarette lighter or
auxiliary power outlet and connect the power cable to the monitor.
Ensure the pin is aligned straight when inserting it into the right side
of the monitor. When hard wiring it is recommended using a “keyed”
power source.
Metal Triangle Mount Bracket If the bracket is needed, please follow
the instructions below. Be sure not to obstruct the driver’s vision
when the monitor is installed.
SENSOR INSTALLATION
1. Remove the tire valve cap and mount the corresponding sensor on
the valve stem using the wrench provided.
2. wrench provided.
3. Simply screw the wrench clockwise.
NOTES:
1. If you have trouble getting the wrench into the location, you can
unscrew the two halves of the
Anti-Theft housing keeping the bottom part of the housing in place on
the sensor and screw the
sensor onto the valve stem by hand. Once the sensor is in place, pull
the lower part of the housing
up and screw the top half of the Anti-Theft housing onto it. The Anti-
Theft housing will now spin
when turned on the sensor. The reverse can be done to remove if
necessary.
2. If you do not need the Anti-Theft function, you may remove the
Anti-Theft cover by just

16
unscrewing the two halves. Mount the inner sensor on the valve
directly.
DELETING SENSOR ID
1. In operating mode, press and hold the CODE button for 3 seconds,
and ID code are displayed. Press the + or - button to select the
desired tire.
2. Press and hold the SET button for 3 seconds. A double-beep sound
will be issued, and you will see FFF FFF after the sensor code is
deleted successfully. Use the + or –key to go to the next tire that you
want to delete. To return to operating mode, press and hold the
“CODE” button for 3 seconds until you hear a beep.
OTHER FUNCTIONS
Typical Scrolling Display During normal operation, the monitor scrolls
through and shows the tires one by one for approximately 6 seconds.
A single audible chirp will be issued if the monitor does not receive
one of the sensors data for more than 30 minutes. You can manually
scroll through and select the tire by pressing the + or –button.
Backlight and Motion Sensor
The monitor has a built-in light and motion sensor. The backlight
turns on when it detects the vehicle is in motion and when it is dark
enough or you may wave your hand in front of the monitor to activate
it. Press any button on the monitor to turn on the backlight manually.
To turn it off manually press and hold the + button for 3 seconds.

17
hold the + button for 3 seconds. The monitor will enter sleep mode to
conserve battery life if the motion sensor does not detect motion for
15 minutes. It will come back to operating mode when it detects the
vehicle is moving again or other motion.
Temporarily Remove Towing Vehicle or
Towed/Trailer Image from Screen
To drop the image of the towing vehicle from the screen press and
release the LINK and + key at the same time. To display it back on the
screen press and release the LINK and + key at the same time again.
(This will allow you to use the system in your towed when not
connected to the coach.) To drop the image of the towed
vehicle/trailer from the screen press and release the LINK and - key at
the same time. To display it back on the screen press and release the
LINK and - key at the same time again.
Charging the Monitor
The lithium-ion battery inside the monitor, when fully charged can
run for up to 60 hours between charges. When the battery symbol
bars are gone, a recharge is required.
OUT OF PARAMETER ALERTS

18
The system cycles from tire to tire every 6 seconds. If there is a
meaningful change in pressure or temperature in this cycle it will
transmit it to the monitor. If not, it will maintain the reading and
transmit a full update every 5 minutes. This is to conserve the sensor
battery. If any reading goes out of the real-time alert; you will notice
three things:
1. An audible alarm.
2. The red light on the lower right side will flash.
3. The corresponding tire on the monitor will flash, and a text
message of what is wrong will appear on the screen.
Press any button on the display and the alarm will stop. However, the
red light will not be turned off until the correct pressure, and
temperature settings are restored to within range.
Replacing Anti-Theft Sensor Battery
When you here the low battery tweet sound coming from the monitor
it is time to replace the battery.
Replace with a CR1632 battery, which operates at -40°F to 176°F.
These can be purchased at many hardware stores, Radio Shack or
large Walmart
on-line at either eBay, Amazon.com or on our site
www.eezrvproducts.com.
NOTE: If a sensor stops transmitting the first thing you want to
check is the sensor battery. When you open the sensor note
the thin black wire, it is the sensors antenna. Do not break it.
Broken antenna wire caused by replacing battery is not
covered under warrantee. Remove the battery and check it

19
with a voltmeter, it should read 3.2V. Anything below 2.8V
should be replaced.
Use the supplied wrench to
remove the sensor.

20
When you open the sensor note the thin black wire, it is the sensors
antenna. Do not break it. Broken antenna wire caused by replacing
battery is not covered under warrantee.
Remove the cover and remove the sensor from the
anti-theft housing.
Use the wrench to hold the inner sensor and remove the upper
portion of the sensor housing.
Take the battery out.
Replace a new CR1632 battery cell, ensure the positive + is facing
upwards. Note the illustration above. Depending on how long the
battery was low you may have to reprogram the sensor.
Check that the water-proof rubber seal is in its proper position. Screw
the sensor cap back on. Reinstall the anti-theft housing.
Flow Through Sensor Battery replacement
When you hear the low battery tweet, the next time you park the
vehicle watch the monitor. Every time the monitor comes to that
sensor the monitor will tweet.
Install CR1632 battery which operates at -40°F to 176°F. These can be
purchased at many hardware stores, Home Depot or large Walmart’s
on-line at eBay, Amazon.com or on our site www.eezrvproducts.com.
Use the hex/Allen wrench provided to remove the anti-theft screw
and take of the sensor. Then use a small Philips screw driver to take
the cap marked “EasyTire” off. Under the cap is the battery. Remove
it and replace it with a new CR1632 battery. Depending on how long
the battery was low you may have to reprogram the sensor.
