Pressure-Relief ValveMAJOR APPLIANCES & ACCESSORIESThe relief valve for over-pressure and over-temperature conditions is located on the exterior of the waterheater. This valve will operate if the water temperature reaches or exceeds 210°F or if the water pressurereaches or exceeds 150 psig. Since the water system in the motor home is a closed system when all water valvesare shut, the water-heating cycle can raise the temperature (and, consequently, the pressure) of the water in thewater heater; thereby realizing pressure increases approaching 150 psig.Should this pressure be reached, the pressure-relief valve will begin “weeping,” that is, minor dripping orleakage from that valve until the pressure drops below 150 psig, at which time the pressure-relief valve will reseatitself and restrict the water flow. This is normal operation and should not be a cause for alarm. Do notobstruct or block the pressure-relief valve in any way, as this would keep the valve from functioning normallyand protecting the hot water system.CB Radio System Antenna ConnectionThe Allegro Bay comes equipped with an antenna and coaxial-cable connection (Figure 4-18) to enable theowner to install a Citizens Band (CB) radio of choice and operate itconveniently from the Allegro Bay. The coaxial-cable connection for theradio is found beneath the dashboard on the driver’s side.Accordingly, with an owner-provided CB radio, that radio can be used tocommunicate with other travelers on the road. To use the one’s CB systemof choice, simply follow the directions furnished with the CB radio. (Note:Channel 11 is considered an emergency channel and monitoring this channelmay give one information about road conditions, accidents, and relatedmatters potentially affecting the travels of the motor-home operator).Figure 4-18. CB Antenna SystemTo talk with someone, simply press the “push-to-talk” switch and speak. To listen to any reply, release the“push-to-talk” switch and listen to the speaker. Remember that communications are “one-way,” not “twoway”simultaneously—one must talk, then allow some listening time for others to talk. Consequently, it’s betterto make brief transmissions and allow others to comment; rather than making prolonged speeches and possiblynot having anyone answer.Observe the common courtesies (see the owner’s manual for more details) and acceptable speech. Severalstates have their Highway Patrols monitor the CB frequencies (check for exact channels for each state ofinterest) to learn about highway problems and emergencies. Be aware of these throughout one’s travels, in theevent that they may be needed.Rear-View Camera Monitor SystemThe rear-view monitoring system (Figure 4-19) is provided to aid the driver inbacking and parking the motor home. A camera mounted on the rear of thevehicle feeds a televised view of the rear of the motor home to the monitorlocated in the front near the driver.4-16Figure 4-19. Rear-ViewCamera Monitoring System
