Maintenance

Fresh Water Tank Draining

Pumping the water out with the self-contained water
pump can empty the fresh water tank. Simply turn on
the pump switch and open a couple of faucets until the
water will no longer drain out, or use the petcock-type
drain valve located on the freshwater tank pan. Be sure
to watch closely and turn the pump off when the tank
runs dry. Pump damage can occur if the pump runs dry
for more than a few minutes.

Water Heater Draining

All models have a drain plug or petcock on the water
heater. Access is from the exterior. The plug or valve is
usually located in the lower-left corner, viewed as you
face the exterior of the water heater.

Sanitizing

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.
a� Multiply "gallons of tank capacity" by 0.13;
the result is the ounces of bleach needed to
sanitize the tank.
b. 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 correct amount of solution (water/bleach)
into the Fresh Water tank and fill 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 4 hours of contact
time to disinfect completely. Doubling the solution
concentration will allow for contact time of one (1)
hour.
6� When the contact time is completed, drain the tank.
Refill with potable water and flush the plumbing of
all sanitizing solution.
