STORAGE AND WINTERIZING (continued)

For additional winterizing protection, add non-toxic antifreeze (approved for drinking

water systems) to your water lines using the following procedure:

1. Reconnect all lines except the hose to the pump inlet port. Close all drain valves

(See Step 3)

*2. Turn bypass valves to bypass position.

3. Attach a length of hose to the pump inlet port. This piece of hose should be long

enough for the free end to be inserted into and reach the bottom of the antifreeze

container.

4. Dilute the antifreeze solution in accordance with the manufacturer’s instructions.

5. Open all water faucets.

6. Insert hose length into the antifreeze container, turn the pump switch on, and run the

water pump until the antifreeze solution ﬁlls all water lines. Flush toilet. Work shower

hand spray while holding down in tub.

7. Shut off the pump and close all faucets.

8. Disconnect the hose length from pump inlet ﬁtting and reconnect water system

inlet line.

*The by-pass valves are located behind the galley cabinet lower door on the Rear Bath

model and under the passenger side lounge on the Mid Bath model.

To access the valves on the Mid Bath model, the recessed panel between the lounge

doors must be removed. Snap the caps off the four screws, remove the screws, and

use the ﬁnger hole in the panel to slide it out.

Turn the water heater valves to by-pass ﬂow position. To by-pass the water heater

for winterizing, close valves A and C and open valve B (See illustration). For normal

operation open valves A and C and close valve B.
