PLUMBING
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 under the lavatory cabinet
in the 33' model (accessed by removing the lower shelf
vertical close-out), under the wardrobe in the 30' model
(pull off the small raised panel door held on by pressure
latches below the wardrobe door) and under the bedroom
wardrobe in the 26' (open the lower door).
For normal operation open valves A and C and close valve
B. (Reverse the valves and drain the water heater for
winterization).
