1.
When possible, park the RV on level ground and drain the fresh water tank, the tank
(storage) water heater and the hot and cold water lines. Open all low point drains and
the fresh water tank drain. Faucets inside the RV should be opened to relieve pressure
to allow water lines to drain. Refer to
Draining the Fresh Water System
section.
2.
Water filter should be removed for winterizing. See
Water Purification System
section.
Cartridge Water Filter
: Remove the cartridge filter and replace it with a bypass
hose (supplied with your RV).
NOTE: Filters should be replaced at the beginning of the camping season
or if they have been exposed to contaminated water, sanitizer or antifreeze.
3.
Turn the (color) valve handles to the POWER FILL position.
4.
Low point drains should be open to remove water from the lines.
5.
Open all faucets in the RV. If there is an outside shower, attach the shower hose to the
shower, and open shower faucets.
6.
Run the water pump until pump is dry (approximately
15 to 20 seconds). Do not operate pump longer than that
without water, it can damage the pump.
7.
After water is drained from the lines, turn the RED,
BLUE, GREEN and WHITE handles so they are at
45°.
8.
Attach a blowout plug to the City Water Inlet on the util-
ity center panel.
9.
Attach the air hose to the blowout plug. Set the com-
pressor to
30 PSI. Red, Blue, Green and White han-
dles must be set at 45° before applying air pressure 30 PSI Max.
10. Blow air into the utility center (
30 PSI Max
). Water lines should be clear in 5 to 10
minutes.
11.
Turn off air supply, remove air hose and blowout plug.
12. Close low point drains, replace the water heater drain plug.
13. Set the colored valves to the WINTERIZE positions.
Refer to the Utility Center manufacturers User Guide for additional operating information.
Grey Water System and Tank
The grey water system consists of the drain water from the sink and the shower.
Shower drain
The water from the shower will drain directly into the grey water holding tank.
Before applying air pressure to the utility center
,
the (4) colored valves
MUST
be set to 45° or damage may occur to the utility center.
Never apply air pressure to the water system with any of the valves in the
closed position. Air pressure applied to a closed valve, faucet or low point
drain could potentially damage the seals and cause water leaks. If you have
questions, consult your RV dealer. Using RV antifreeze is the preferred meth-
od of winterization.
Recommended air pressure is 30 PSI MAX
.
Exceeding this pressure may
rupture water line couplings and void your warranty.
