Volt Dc Demand Pump (Option); Sanitizing And Filling The Potable Water System (Option); No Fresh Water Tank - Jayco COVE 2002 Owner's Manual

12 Volt DC Demand Pump (Option)

When water is desired and you are not hooked up to city water, you need
to turn on 12 volt DC power to start the demand pump. Fig. 4-3 shows a
typical demand pump set up. Depending on your park trailer model, the
demand pump will be located under the bed, in a cupboard, or under the
sink. The switch to operate the pump is located on the monitor panel.
Energy for the pump is supplied by the auxiliary battery or converter.
The pump will self prime when started and provide water for your park
trailer. The pump continues to run until approximately forty pounds of
pressure is achieved and automatically starts again when pressure drops
to twenty pounds. Some cycling in the pump may occur, depending on
the volume of water being released. A check valve is built inside of the
pump to prevent water from flowing into supply tank.
NOTE: The water pump switch should be in the off position when the trailer is left
unattended for any amount of time. If something would happen to the water system,
this will ensure that water damage will be restricted to a small area.

Sanitizing and Filling the Potable Water System (Option)

Potable water systems require periodic maintenance to deliver a consistent flow of fresh water.
Depending on use and the environment the system is subject to, sanitizing is recommended prior to
storing and before using the water system after a period of storage. Systems with new components,
or ones that have been subjected to contamination, should also be disinfected as follows:
1. Use one of the following methods to determine the amount of common household bleach
needed to sanitize the tank.
• Multiply "gallons of tank capacity" by 0.13; the result is the ounces of bleach needed to
sanitize the tank.
• Multiply "liters of tank capacity" by 1.0; the result is the milliliters of bleach needed to
sanitize the tank.
2. Mix the proper amount of bleach into a container of water.
3. Pour the solution (water/bleach) into the tank and fill the tank with potable water.
4. Open all faucets (Hot and Cold) allowing the water to run until the distinct odor of chlorine is
detected.
5. The standard solution must have four (4) hours of contact time to disinfect completely.
Doubling the solution concentration allows for contact time of one (1) hour.
6. When the contact time is completed, drain the tank. Refill with potable water and purge the
plumbing of all sanitizing solution.
If there is a problem of excessive chlorine odor and taste after the sanitizing process, follow the
above procedures using a solution of baking soda (1/2 cup added to one gallon (4 liters) of water per
15 gallons (60 liters) of tank capacity) or vinegar (one quart added to five gallons (20 liters) of water
per 15 gallons (60 liters) of tank capacity.)
Your demand water system is now ready for use.

No Fresh Water Tank

The standard plumbing system on your park trailer does not have a fresh water holding tank. This
design does not need to be sanitized since the water lines will be drained for winterizing and water
will not be allowed to "set" in the system. Refer to the drainage instructions in this manual for
reference to draining your water lines.
