HOSES, PIPES, TUBES AND FITTINGS
The hoses, pipes, tubes, and fittings used in your LP system are designed to withstand pressures far
exceeding those of the LP system. However, because environment and time can both contribute to the
deterioration of these components, they must be inspected for wear at regular intervals. Be sure to inspect the
hose before each season and when having the tank refilled. Look for signs of deterioration such as cracks or
loss of flexibility. When replacing the hose or other LP components, make sure to always replace them with
components of the same type and rating (check with your dealer).
Fittings are used to connect the various system components to each other. The P.O.L. fitting at the end of the
LP supply hose is made of brass so that pipe sealants are not necessary to prevent leaking. It also has a
left-handed thread, which means that it is turned clockwise to remove, and counter-clockwise to tighten. The
P.O.L. fitting has been designed to help restrict the flow of LP gas in the event of a regulator failure, or hose
malfunction.
LP GAS LEAK DETECTION SYSTEM
HOW TO OPERATE
Your LP Gas Leak Detector is powered at all times when the battery is connected. If your coach is equipped
with a master cutoff switch, the detector will be turned off when this switch is turned OFF. When the
detector is powered by connecting the battery or turning ON the master cutoff switch, the green indicator will
light. After 60 seconds, the detector will begin monitoring the air in your coach for combustible vapors. The
propane you use to cook, refrigerate, and heat is combustible. Should a leak occur, your Pre-Tell 1 will
produce a pulsating alert sound when the gas reaches the detector. This alert will continue to sound until the
gas has dissipated or until the reset button is pressed.
When the alert sounds, open all doors and major
windows to air out the coach and turn the gas off at the tank. Do not reenter the coach until the alert
stops sounding. If the alert sounds a second time after the gas is turned back on, leave the gas off and
have a qualified LP Gas Dealer or RV Service Center make the necessary repairs.
The reset button only
stops the alert from sounding for 60 seconds. This device is intended for detection of LP Gas ONLY.
HOW TO TEST
The detector must be operating for at least 60 seconds before it can be tested. Expose the detector to gas*
and observe that the alert sounder will begin to alarm. The alert will continue to sound until:
1. The gas mixture at the detector returns to a safe level.
2. The reset button is pressed. If the reset button is pressed, the detector cannot be retested for at least
60 seconds.
