====Commercial Water Hookup====

When facilities are available, the Commercial Water hookup can be used to supply all coach water system requirements. In this manner, the coach water tank and pump system are automatically bypassed by the supply line check valve and water pressure is developed by the external connection. Water inlet pressure is regulated to 40-psi by a valve which is part of the combination city (commercial) water fill, check valve, and regulator shown in figure 5-1.

[[File:1989 WB 40 Figure 5-4 Water Purifier.png|right|frameless]]

The major components of the potable water distribution system are the bacteriostatic water purifier , water tank(s) , water pump , air accumulator , water heater, piping and fixtures . The air accumulator and water pump are shown in figure 5-3; the water purifier and water tank drain valve are shown in figure 5-4. Water Pump The water pump, figure 5-3 , is equipped with a factory-calibrated pressure control switch which is preset to turn the pump on when the system pressure falls below 20 psi; and turn the pump off when the pressure reaches 35 psi. If the pump has been out of service for a period of time , it is advisable to open a faucet before turning the _pump on. When water flows steadily from the opened faucet , close faucet and observe that pump shuts off when system becomes pressurized . (it may also be necessary to bleed the air from the other faucets as well.) When the potable water supply tank(s) level is low, or empty , shut the pump off to prevent possible damage to the pump motor. In addition to integral motor overload protection, the pump mechanism · is also protected from jamming by the presence of an in line filter (pump guard) between the pump and the supply tank .

==== Water Purifier ====

====Water Purifier====

The bacteriostatic water purifier, figure 5-4, filters and purifies the potable water supply to eliminate tastes , odors and coloration produced by chlorine, rust, insecticides , detergents , sediment and other foreign objects . Satisfactory elimination of water-borne disease-carrying bacteria is accomplished by a hygienic filter bed which consists of silver ions absorbed on sponge silver metal which is deposited in a finely divided form on granular activated carbon of high surface area. An added benefit is that even though the coach is not used for some time, bacteria will not grow in the water distribution system. Each time the filtered water supply is used for drinking or cooking purposes, run the tap for a few seconds to clean out the line prior to using the water. This is particularly important if the water tap is not used on a daily basis. If the water supply has not been in use for extended periods, allow the water to flow for a minute or two before use.

==== Purifier Replacement ====

====Purifier Replacement====

Depending upon the condition of the municipal water used, the filter media will normally process 75,000 gallons of water before the purifier will need to be replaced. For the majority of "Wanderers " this means there will be at least five years of useful life. The only practical way to determine when replacement is required is to go by the sense of taste. If a faint taste of chlorine is detected , it is time for a change. Even when there is a noticeable taste the bacteria stopping proper ties have not been compromised.

===LPG Tank and Controls===

===LPG Tank and Controls===

The LPG supply tank is located in a curbside compartment as shown in figure 6-1 . LPG system controls include a main gas service valve, two stage pressure regulator , filler connection with Auto Stop {80%) fill valve, 20% vapor (stop filling when liquid appears) valve, and the pressure relief valve. Down stream of the pressure regulator is a solenoid operated shut off valve.  

The LPG supply tank is located in a curbside compartment as shown in figure 6-1 . LPG system controls include a main gas service valve, two stage pressure regulator , filler connection with Auto Stop {80%) fill valve, 20% vapor (stop filling when liquid appears) valve, and the pressure relief valve. Down stream of the pressure regulator is a solenoid operated shut off valve.  

'''Warning''' When coach is to be stored in a confined area, turn off the LPG at the main tank shutoff valve (figure 6-1 ).

Most gas appliances are intermittently operated.  However, operation during cold weather conditions does cause a heavy use of the gas furnaces. Extensive oven usage also consumes a great deal of fuel. The amount of LPG consumption depends on the total use and manner of use of these appliances. Note that each gallon (4 ¼)lbs of LPG fuel produces approximately 91,500 BTU's of heat energy. The LPG tank used in your coach will furnish over 3 million BTU's. For your guidance in estimating your anticipated fuel consumption, the following is a listing of typical appliance consumption ratings when the appliance is operated for one hour:

|Furnaces (3)

A flexible hose from the two stage pressure regulator connects to tubing which carries the LP gas to the electrical solenoid shutoff valve, and manifold to individual appliances. The solenoid valve is actuated by either a high pressure condition (caused by a defective regulator), or by the remote LP leak detector , located below the refrigerator door. Tank level can be monitored at the Systems Monitor panel. To read the digital display , press the Propane Tank button .  

Warning LP gas containers shall not be placed or stored inside the vehicle. LP gas containers are equipped with safety devices which relieve excessive pressure by discharg ing gas to the atmosphere.

 

 

# Open Window. This warning label has been located in the cooking area to remind you to provide an adequate supply of fresh air for combustion. Unlike homes, the amount of oxygen supply is limited due to the size of the recreational vehicle , and proper ventilation when using the cooking appliance(s) will avoid dangers of asphyxiation. It is especially important that cooking appliances not be used for comfort heating as the danger of asphyxiation is greater when the appliance is used for long periods of time. A warning label has been located near the LP gas container. This label reads.  '''Do not fill container(s) to more than 80 percent of capacity.'''  Overfilling the LP gas container can result in uncontrolled gas flow which can cause fire or explosion. A properly filled container will contain approx - imately 80 percent of its volume as liquid LP gas.

 

Warning Portable fuel-burning equipment, including wood and charcoal grills and stoves, shall not be used inside the recreational vehicle. The use of this equipment inside the recreational vehicle may cause fires or asphyxiation.

 

Warning Do not bring or store LP gas containers, gasoline or other flammable liquids inside the vehicle because a fire or explosion may result. The following label has been placed in the vehicle near the range area: If You Smell Gas:

 

# Do not touch electrical switches.

# Shut off the gas supply at the tank valve(s) or gas supply connection.

# Have the gas system checked and leakage source corrected before using again.

 

LP gas regulators must always be installed with the diaphragm vent facing downward. This will minimize any chances of vent blockage which could result in excessive gas pressure causing fire or explosion.
