05 Major Appliances

Residential Refrigerator

Some coaches contain the optional 110 volt style residential refrigerator (Figure 5-1), which is powered from an outside source, or from the unit’s generator or inverter, which uses a 12 volt battery power supply.

This unit operates as most home refrigerators do.

For further operating and maintenance instructions, refer to the operating booklet found in the Owner’s Information Package.

The inverter must be ON for the residential electric refrigerator to operate, if not connected to shore power, or if the generator is not running.

Ice Maker

Your ice maker (Figure 5-2), is equipped with an automatic shut off. As ice is made, the ice cubes will fill the storage tray, raising the shutoff arm to the OFF position. Do not force the wire shut off arm up or down.

• To turn ON the ice maker, lower the wire shutoff arm.
• To turn OFF the ice maker, lift the wire shutoff arm to the OFF position (arm up) until it clicks.

Microwave Oven

The Allegro Breeze contains a standard convection/microwave (Figure 5-5). All microwave ranges operate on 120 volt AC electrical power, supplied either by the external electrical hookup or by the onboard electrical generator in the motorhome.

Touchpad controls are used for operating the convection microwave (i.e., cooking temperature, mode, power level, and cooking time). For basic operating instructions, care, and maintenance for the proper use of the microwave, refer to the specific manual in the Owner’s Information Package.

Air Filtration Fan

In the motorhome, the “exhaust” or air filtration fan (Figure 5-4) is built into the microwave, and its function is to filter the air and exhaust to the outside.

The filtration fan must be used whenever cooking is performed to filter any airborne cooking residues and heated air.

The air filtration system can be used as supplemental filtration of other odors and gases including tobacco smoke, candle fumes, and related vapors. It contains filters, which can be removed and cleaned or replaced to ensure normal operation. Consult the particular owner’s manual contained in the Owner’s Information Package for more information

 Cook Top 

The Allegro Breeze is equipped with a three-burner cook top (Figure 5-7). To ignite the burner, gently push in and turn the control knob to IGNITE.

Once the burner is lit, maintain the knob in this position for a few seconds to ensure the flame remains ignited. To regulate the flame, turn the knob to the desired cooking flame.

Water Heater

Before the water heater is to be used, fill the fresh water system and purge the water lines to and from the water heater by opening all the hot-water faucets, until water steadily flows from each one and no spurting or hissing sounds are heard.

The water heater ( Figure 5-9), uses either the LP gas system or the 120 volt AC electrical system to operate the heater.

Motorhome models with a washer/dryer unit are supplied with a ten-gallon water heater. Motor Homes without a washer/dryer unit come with a six-gallon water heater.

Proper and safe operation of the water heater requires that all safety information provided in the owner’s manual be read and understood before placing the water heater in service.

Take the time to become familiar with this manual (provided in the Owner’s Information Package).

Water Heater Storage

If the motorhome is to be stored during the winter months, the water heater (Figure 5-9) should be drained to prevent damage caused by freezing water contained in the water heater.

To drain the water heater, first turn OFF all electrical power, turn OFF the LP gas going to the water heater, then turn OFF the water pump. Open both the hot and the cold-water faucets to drain the water lines and open the drain on the water heater to drain the entire system.

When re-activating the water heater after the motorhome is taken out of storage, make sure that the entire water system, including the water heater, has been filled with water and the lines have been purged of any entrapped air before relighting the water heater. Failure to do so might allow the waterheating element to be turned ON before it is immersed in water; thereby, causing the premature failure of the heating element and voiding the warranty.

Pressure Relief Valve

The relief valve (Figure 5-10) for over-pressure and over-temperature conditions is located on the exterior of the water heater. This valve will operate if the water temperature reaches or exceeds 210°F or if the water pressure reaches or exceeds 150 psig.

Since the water system in the motorhome is a closed system when all water valves are shut, the water heating cycle can raise the temperature and, consequently, the pressure, of the water in the water heater; thereby realizing pressure increases approaching 150 psig.

Should this pressure (i.e., 150 psig) be reached, the pressure-relief valve will begin “weeping,” that is, there will be minor dripping or leakage from that valve until the pressure drops below 150 psig, at which time the pressure-relief valve will reseat itself and restrict the water flow. This is normal operation and should not be a cause for alarm. Do not obstruct or block the pressure-relief valve in any way, as this would keep the valve from functioning normally and protecting the hot water system.
