The water heater switches are typically located on the monitor panel. Refer to the Monitor
Panel section for function details.
When your RV is new.
At the beginning and end of each season.
When the water system becomes contaminated or every three months of use.
1. Level the recreation vehicle and drain the fresh water system (see Draining the Fresh
Water System).
2. Water heater power switches should be turned OFF (12V gas and 120V electric at the
command center). Gas valve at the water heater should be turned OFF.
3. Bypass the tank (storage) water heater (if so equipped). See photos above, or for a 3
valve bypass; set the water heater bypass valves to BYPASS (middle valve ON supply
valves OFF). Water heater power should be OFF, gas valve to water heater should be
OFF also.
4. Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite
solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of
solution for every 15 gallons of tank capacity. This will result in a residual chlorine
concentration of 50 ppm in the water system.
If a 100 ppm concentration is required, use ½ cup of household bleach with one gallon of
water to prepare the chlorine solution. One gallon of the solution should be used for each
15 gallons of tank capacity.
5. Put the sanitizer into the fresh water tank by pouring the solution into the gravity ll
inlet on the outside of the RV.
6. Finish lling the fresh water tank by pouring fresh water into the gravity ll inlet. A
pressurized water source can be used, but the hose will not screw on to the gravity ll
inlet, use a funnel or hold the hose up to the inlet.
7. When the water tank is full (check moni-
tor panel for tank levels). Remove the
hose from the inlet and the water source.
Turn the water pump ON.
8. Make sure the water tank shuto valve (at
the pump) is turned ON. Siphon valve (at
the pump) should be turned OFF (Fig. 1).
9. Open the hot water line on all the faucets
(kitchen, lavatory, shower and outside
shower) until water begins to ow con-
tinuously and a chlorine smell is notice-
able. Water will not ow until a xture is
opened inside the RV.
Fresh water tank sizes vary by model; contact your dealer
or Customer Service for your specic tank size.
