PLUMBING SYSTEMS
generator must be operating, or the chassis
engine must be running (such as when driving
down the road). These three sources can prevent
excessive discharge of the house battery.
NOTE: The holding tank heater pads are electri-
cal resistance type heating elements.
These types of heating elements typically
use large amounts of current while oper-
ating. If the tank heaters are used with-
out a recharging source, it will drain the
house batteries in a relatively short
period. Typically, the batteries would not
support overnight heating without a
supplemental charging source.
Holding Tank Level Indicators
The holding tanks may be monitored on the
wall mounted monitor center.
Press the “Levels Test” switch to check the
level in each tank.
See Section 8 - Appliances for further infor-
mation on the monitor panel.
WATER LINE & TANK DRAIN VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the follow-
ing illustration.
Drain valve locations are listed on the follow-
ing pages.
Water System Winterization Valve
Your coach is equipped with a manually
operated water line winterization system for
your convenience in winterizing fresh water
lines.
The system features a diverter valve and suc-
tion tube in-line between the tank and water
pump to draw non-toxic RV water system anti-
freeze into the water lines. This feature is located
near the water pump and drain valves. See page
7-5 for location in your coach.
To Fill Lines with RV Water Line Antifreeze
·
Turn water heater by-pass valve to BY-PASS
position.
·
Remove and save the protective cap from the
end of the suction tube.
·
Insert the end of the tube into a container of
RV antifreeze solution.
·
Turn the diverter valve handle so that it points
toward the suction tube.
·
Turn a water pump switch on.
·
Open each cold water faucet handle in the
coach one at a time until antifreeze solution
just begins to flow from the faucet, then
close.
When Done Adding RV Antifreeze:
·
Turn water pump switch off.
·
Turn the diverter valve handle so it points
toward the water line to the pump as shown in
the photo. This will stop the flow from the
suction tube and revert the tank line flow to
the pump.
·
Replace the protective cap onto the end of
the suction tube to keep out insects and debris
when not in use.
