Water Pump
The 12-volt Sure Flo water pump is located beneath the floor pane! in the wardrobe dircethy behind
the driver scat (TS and TD models). To lift the flocr panel, there arc nwo screws that arc to be
removed. The filter and the inlet connection are visible on Ure top of the water pump. Activate the
water pump using the pump switch at the bottons of the monitor pancl located above the passenger
side entrance door. Please consult your Sure Flo operating manual for complete operating and
maintenance instructions.
Winterizing
1) Drain your fresh water tank. The fresh water tank is located on the driver side in front of the
rear axle (see page 21 for approximate location). Open the drain spigot by turning the top lever
and let the water drain (there may be a small amount of water left in the tank after it is
drained.).
2) Drain your hot water tank. First, relieve pressure inside the hot water tank with the pressure
relief valve located at the top of the hot water tank. Then remove the anode rod at the bottom of
the water heater tank on the outside of the vehicle. The anode rod is a | 1/16” nut. Loosely
reinstall the anode rod after the water heater is drained, this will prevent dust and insects from
entering the heater while in storage.
3) Turn the water heater bypass valves to the winter position. The water heater bypass valves are
located underneath the rear electric sofa bed on the driver side. You can access the by-pass
valves through the rear doors and reaching under the electric sofa bed.
4) The winter position means that the valve handle at the top of water heater on the red line should
be closed and the valve at the bottom of the water heater on the blue line should be closed. The
valve in between where the red and blue lines connect should be open (the valves are closed
when the handle of the valve makes a T with the water line).

Remove the water line from the inlet side of the water pump (this is the clear plastic line going
into the water pump filter.) Connect a siphon hose to the inlet side of the water pump place the
other end in a container RV non-toxic antifreeze. Turn on you’re the pump. This will pump
non-toxic RV antifreeze through all of your fresh water lines.
NOTE: Siphon hose consists of 40” of “2” clear tubing with a fitting to attach to the water pump.
The fitting can be purchased through an RV dealer.
6) Open the kitchen and bathroom faucets one at a time allowing the antifreeze to flow through
both the hot and the cold sides. Be sure to also open the toilet valve and exterior shower faucet.
Turn off the water pump and disconnect the siphon hose, reattach the original fresh water
supply fitting.

7) Pour % cup of RV antifreeze down each drain (kitchen sink, bathroom sink and shower drain).
8) Fully charge your auxiliary coach battery and turn off and remove the red key disconnect. The
red key disconnect is located behind the rear power sofa bed accessed through the two rear
doors on the passenger side.
9) Turn you thermostat to the off position.
10) Turn your propane tank off.
11) Place your fridge door in a slightly open position for air to circulate through the fridge..
It is recommended that you start and run your vehicle and generator once a
month during the winter season.
Winter Use
We recommend that the water system not be used when the outside temperature drops below the
freezing point. You should ensure that your unit is completely winterized by that time. If it is
necessary to use the water system, We sugges! that you bring containers of fresh water with you and
add non-toxic RV antifreeze to the gray and black water holding tanks. NOTE: Keep in mind that
as you add more water to the holding tanks the antifreeze will dilute more than the recommended
amount and may start to freeze earlier at cold temperatures. Do not use the exterior shower.
