13. Remove the battery from your trailer and store in a cool dry place where there is
no danger of freezing. It is very important for optimum life of a battery to check it
periodically and to keep it fully charged.

aged by freezing - or might damage the trailer if containers break.
For additional winterizing protection add a non-toxic antifreeze (approved for drinking
water system) to the water lines using the following procedure.
1. Reconnect all lines except the hose to the pump inlet port. Close all drain valves.
2. Turn water heater by-pass valves to the by-pass position. See Shut off Valves expla-
nation in this section.
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 hand
shower spray while holding down in tub.

inlet line.
