Winnebago Sunstar 2023 APPLIANCES AND SYSTEMS User Manual

APPLIANCES AND SYSTEMS

The appliances installed in your motorhome are manufactured by reputable RV appliance makers and have been tested by independent laboratories to meet all applicable standards and codes set for RV appliances. See Section 2 – Safety and Precautions of this manual for any safety and precautions you need to take regarding the operation of your appliances.

REFRIGERATOR 12V

The refrigerator in your motorhome can operate from either of two energy sources available to the motorhome:

120-Volt AC Electric-through 12V converter power
12-Volt DC Electric

WARNING
Do not let children play inside the motorhome unattended. Unlike your home refrigerator/freezer that one could push open the door from the inside, your motorhome refrigerator has a travel latch and when engaged would trap a child inside resulting in suffocation leading to death or serious injury.

Basic Operation

Switch on the Refrigerator
The refrigerator control ranges from “1”, cold setting, to “7”, coldest setting. When you start up the refrigerator, turn the thermostat to a colder setting. Allow 24 hours for your refrigerator to cool completely before storing food. Then adjust the thermostat by one increment at a time to the desired temperature.

NOTE: The refrigerator will retain temperature more efficiently if food is cold before placing inside.

Further Information
Refer to the manufacturer’s user guide provided in your Info Case for complete operating instructions, safety precautions, and maintenance information.

WARNING
Cover must be in the full open position when any top burner is in operation. After use of top burner(s), let top burner grate cool before replacing top cover.

To Light Range Top Burners
Lift glass range cover.
Depress the desired burner knob and turn counter-clockwise to the ON or LITE position (do NOT attempt to light more than one burner at a time). Turn the SPARK knob, you will hear the igniter “click”.

NOTE: If the burner does not light within about ten seconds or if the flame should go out during cooking, turn the burner off. If gas has accumulated and a strong gas odor is detected, open a window and wait 5 minutes for the gas odor to disappear before relighting the burner. If the appliance has not been operated for a period of time, the surface burner may be difficult to light due to air in the gas line.

To extinguish the burner flame, turn desired burner knob to OFF.

NOTICE

Avoiding Asphyxiation
The following warning label has been located in the cooking area to remind you to provide an adequate supply of fresh air for combustion.

DANGER
Do not use gas cooking appliances for comfort heating. Can lead to carbon monoxide poisoning, which can lead to death or serious injury.

WARNING
Gas cooking appliances need fresh air for safe operation.

Before operating:
Open vents or windows slightly or turn on exhaust fan prior to using cooking appliance. Gas flames consume oxygen, which should be replaced to ensure proper combustion. Improper use can result in death or serious injury.

Unlike homes, the amount of oxygen supply is limited due to the size of the recreational vehicle, and proper ventilation when using the cooking appliances avoids dangers of asphyxiation. It is especially important that cooking appliances not be used for comfort heating, as the danger of asphyxiation is greater when the appliance is used for long periods of time. FAILURE TO COMPLY COULD RESULT IN DEATH OR SERIOUS INJURY.

WARNING
Portable fuel-burning equipment including wood and charcoal grills and stoves, shall not be used inside the recreational vehicle. The use of this equipment inside the recreational vehicle can cause fires or asphyxiation. Failure to comply could result in death or serious injury.

NOTICE
Turn off the range and allow it to cool before closing the range cover. The range cover is made of glass and may shatter when heated.

MICROWAVE OVEN

Refer to the manufacturer’s user guide located inside the appliance for complete operating instructions.

NOTICE
Do not store items in oven. If oven would turn on stored items can ignite resulting in fire and or property damage.

RANGE HOOD

The range hood vent draws cooking odors and airborne grease particles into the filtration grid and either recirculates the air or vents it to the outside of the motorhome, depending on model. A light on the underside of the hood provides illumination for cooking and food preparation.

Further Information
See the manufacturer’s user guide provided in your Info Case for instructions on the replacement of light bulbs and replacement or cleaning of grease filter elements.

NOTE: Some models may be equipped with a Water Pump switch in the water service center on the outside of the motorhome or within the bathroom area for your convenience.

WATER HEATER – GAS –If Equipped

NOTE: Read the Water Heater operating guide provided in your Info Case for complete operating instructions, safety warnings, and maintenance information before operating the Water Heater.

Ensure the Water Heater is filled with water before operating
To fill the Water Heater, turn the Water Pump switch ON and open a hot water faucet anywhere in the motorhome. When water begins to flow steadily from the faucet, the Water Heater is full.

Propane Gas Operation

Your motorhome is equipped with one of the following System Monitor Panels shown below.
Press the Water Heater switch (located on the Systems Monitor Panel) to the ON position.

The Water Heater button is located on the “Home” Screen
-Typical View

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 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 approximately 5 minutes, then turn back on.

Further Information
See the Water Heater manufacturer’s operation manual provided in your Info Case for complete operating instructions, safety warnings, and maintenance information.

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.

Water Heater Exterior Service Access
-Typical View

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
Hot water can escape from tank causing injury. Operate this valve only when the tank water is cold.

To Replace the Air Gap:

Turn off the Water Heater switch and incoming water supply (city water and/or demand pump).
Open a faucet in the motorhome to relieve water pressure.
Pull the handle of the P-T valve straight out and allow water to flow until it stops.
Let the handle of the P-T valve snap shut.
Close the faucet and turn on the water supply before switching the water heater on. Manually operate the pressure temperature
relief valve at least once a year.
NOTE: If your water heater is equipped with the motoraid system, it uses an extension from the engine cooling system to heat water in the water heater while driving. The engine cooling system must also be cold before opening the pressure-temperature relief valve. See “Motor aid Water Heater” for more information.

FURNACE – PROPANE GAS –If Equipped

To Start Up

Open the Propane Gas Tank valve by turning fully “counter-clockwise”.
From the “Home” screen on the monitor panel select the temperature icon to open the climate screen. The temperature of the front and the rear of the motorhome can be adjusted using the up and down arrows to the desired temperature.

Press the temperature icon to access the climate screen.
-Typical View

Use the up and down arrows to adjust the front and the rear of the motorhome to the desired temperature.
-Typical View

The furnace fan should start to blow immediately after setting the thermostat.
After approximately 30 seconds, the furnace burner should light.
The furnace should now cycle off and on automatically as the thermostat demands just like a household furnace.

If heat does not come out of the heat ducts after a minute or so, the burner is not lit. Turn the thermostat off for 3-5 minutes, ensure Propane Gas Tank valve is open and tank is not empty, then repeat Steps 2-4. If the furnace will not light after three attempts, go to “Shut Down” steps and contact your dealer or a local RV service center for repair.

NOTE: If the furnace burner has any residuals of metal protectant or lubricants used during manufacture of the furnace, it may smoke slightly when the furnace is used for the first time and may set off your smoke alarm. We recommend that you provide adequate ventilation when using the furnace for the first time to avoid a nuisance smoke alarm. We do not recommend removing the smoke alarm battery.

To Shut Down

Below the temperature adjustment arrows for the front and the rear, push the “OFF” button on both.
Close propane tank valve if motorhome will be stored for a period of time.

Further Information

Refer to the manufacturer’s user guide provided in your Info Case for further information, including operating precautions, and periodic maintenance. See “Motorhome Maintenance Chart” in Section 11 – Maintenance and Storage for recommended intervals.

DUCTED ROOF AIR CONDITIONING SYSTEM

The furnace thermostat also controls ducted roof air conditioner operation when the Thermostat switch is placed in “Cool” position.
All cooling functions controlling to setpoint have a short cycle protection time delay of three minutes. There will be no delay if the cycle OFF time exceeds three minutes.

NOTE: The ducted roof air conditioning system has ceiling registers that can be closed if necessary to force more cool air toward a specific area of the motorhome or to route cool air away from a specific area. If too many vents are closed, however, it can cause the air conditioner unit to shut down, particularly in high humidity conditions.

Further Information
Refer to the manufacturer’s user guide provided in your Info Case for complete operating instructions.

AIR CONDITIONER FILTER

The washable foam air conditioner filter is located in the ceiling-mounted return A/C grille in the lounge area of the motorhome. It is recommended to check the filter monthly for dirt build-up and cleaned or replaced, as necessary.
