SECTION 4
APPLIANCES & SYSTEMS
4-10
Class A
The energy management system (EMS) will
shut down the electric water heater element while
the microwave oven is being used to avoid an
overload condition. It will turn it back on when
the microwave shuts off.
This does not normally present a problem in
providing hot water since microwave use is
typically brief and the water heater is well
insulated.
If this does present a problem for your water
heating needs, you may wish to switch to propane
gas operation to continue water heating function
while the microwave is being used.
For Propane Gas Operation
Press the Water Heater switch on the Monitor
Panel. The “Pilot Out” light will glow for about
10-15 seconds, then it will go out. The “Heater
On” indicator will remain lit. If the “Pilot Out”
light comes on during propane operation, it
means that the burner has gone into “lockout”
mode and must be restarted. If this happens, turn
the Water Heater switch off for about 5 minutes,
then turn it back on. See the water heater user’s
guide in your InfoCase for further information.
For Quick Recovery Operation
(Dual)
Turn on both Water Heater switches; the gas
one on the monitor panel and the electric one.
This will help reheat the water heater tank more
quickly than a single source would alone. Use
this mode when you are using a larger than nor-
mal volume of hot water.
To Turn Water Heater Off
1. Turn switch on monitor panel to Off position.
2. Turn electric water heater switch off.
3. Turn off propane gas supply (if not to be used
for extended period).
4. Drain water heater tank if the coach is to be
stored or water heater will be Off during
freezing temperatures. (See Draining and
Storage Instructions in
Water Heater
Operation Manual
in your InfoCase.)
PRESSURE-TEMPERATURE
RELIEF VALVE
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Normally there is an air gap at the top of the
water heater tank which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to “weep”
until the air gap is manually replaced.
CAUTION
Operate This Valve Only When The Water
Heater And Engine Cooling System Are
Cold!
