N41X N51X

Owner’s Manual 4

Page 5

For the best cooling performance:

T emperature control system:

- Let air move freely inside the entire food compartment.

- Do not cover the shelves with plastic, paper, etc.

To decrease the amount of ice that collects on the cooling fins:

- Cover all liquids and moist foods.

- Let all hot foods cool before putting them in the refrigerator.

- Do not open the door any longer than necessary.

Flip-up shelf:

The flip-up shelf supplies a space to store tall bottles. To use the flip-up shelf, lift the center of the shelf and fold it up against the inside wall of the refrigerator.

Door Bins:

You may put the door bins [52] of the fresh food compartment in a location that best meets your need (See Art01114). To remove the bins, lift them over the locator and pull them forward. To install the bins, push them onto the locator.

NOTE: Do not wash the door bins in a dishwasher. The door

bins are not dishwasher safe.

Freezer compartment:

The freezer compartment is made to keep pre-frozen food frozen and not to quick freeze food. Keep pre-frozen foods in the freezer compartment.

NOTE: Do not put other items on the ice tray while the water is

freezing. The water freezes more rapidly if the thermostat is at the coldest temperature setting.

Door latch for travel and storage:

During travel, the door latch prevents the door from opening. There are no chains, slides, or any devices that you must engage.

During storage, the door latch prevents the door from completely closing. Use it to prevent odors when the refrigerator is shut down for a long period of time.

To use the door latch for storage (See Art00979):

- Open the door just so the door latch [161] is between the ribs [166] of the latch plate [162].

Although the refrigerator is not frost -free, it is made to limit frost on the cooling fins. At regular intervals, the temperature control system automatically melts most of the frost from the cooling fins. The water from the cooling fins drains into a collection cup that is attached to the back of the refrigerator. The heat of the cooling system evaporates the water from the collection cup.

Operating the Refrigerator Controls

Control panel:

The refrigerator control panel (see Art01562) is above the refrigerator door. A 12 volt DC power supply is necessary for the control functions of the refrigerator to operate. The refrigerator receives DC power from the 12 volt system of the vehicle; either an auxiliary battery, a converter, or the vehicle engine battery.

The ON / OFF button [30] starts and shuts down the refrigerator:

- To turn on the refrigerator, push and release the ON / OFF button.

- To turn off the refrigerator, push the ON / OFF button for two seconds and then release.

The TEMP SET button [32] controls the temperature adjustment of the freezer and the fresh food compartment. The temperature adjustment that you select does not change if the mode of operation of the refrigerator changes.

- Push the TEMP SET button and the temperature setting “19” appears in the center display [33].

- Push and hold the TEMP SET button and the temperature setting changes.

- When the desired temperature setting shows, release the TEMP SET button.

Owner’s Manual 5

Page 6

- The temperature setting shows for ten seconds and then the current operation mode of the refrigerator shows.

- If the air in the propane gas supply lines prevents the burner from ignition on propane gas, the fault code “F” will appear in the center display.

- The number “9” is the coldest temperature setting.

The MODE button [31] controls the operation mode of the refrigerator.

- Push and hold the MODE button and a light bar shows in the center display beside each of the four operating modes of the refrigerator, one at a time.

modes of operation.

- When the light bar shows beside the mode of operation that you choose, release the MODE button to operate the refrigerator in that mode.

Automatic mode operation:

When the refrigerator is in AUTO mode, it automatically uses the most efficient energy source that is available for operation. During operation, if a more efficient energy source becomes available, the refrigerator controls change from the current energy source to the more efficient energy source as follows:

- The first choice is AC operation if 120 volts AC is available to the refrigerator.

- The second choice is propane gas operation if 120 volts AC is not available to the refrigerator.

- The third choice is DC operation (3-way models only) if neither 120 volts AC nor propane gas is available to the refrigerator.

Removing air from the propane gas supply lines:

For safety reasons, the burner is made to ignite on propane gas within a specified amount of time. When starting the refrigerator for the first time, after storage, or after replacing propane gas tank, the propane gas supply lines can have air in them. Due to the air in the gas supply lines, the burner may not ignite on propane gas within the specified amount of time.

To remove the air from the propane gas supply lines:

- Make sure that all of the gas valves are open.

- Push the ON / OFF button to turn the refrigerator on.

- Push and hold the MODE button until the light bar beside LP GAS [36] shows.

- This means that the refrigerator is operating on propane gas.

- Push the MODE button and the refrigerator will start a 30 second trial for ignition.

- During the 30 second trial for ignition, the refrigerator controls open the gas safety valve and the igniter sparks.

- After 30 seconds, the refrigerator controls closes the gas safety valve and the igniter stops sparking.

- When the light bar beside the LP GAS shows and no fault code remains, this means that the refrigerator is operating on propane gas.

- At this time, all of the air is removed from the propane gas supply lines and you may select AUTO mode of operation if you wish.

- Depending on how much air may be in the propane gas supply lines, you may need to repeat the 30 second trial for ignition two or three times.

- If the burner does not ignite on propane gas after two or three attempts, stop and consult your local dealer or an authorized Norcold Service Center.

Set the controls to automatic mode operation:

- Push the ON / OFF button to turn the refrigerator on.

- Push and hold the MODE button until the light bar shows beside AUTO [34] and then release.

- If 120 volts AC is available to the refrigerator:

- The light bar beside AC [35] also shows in the center display.

- After ten seconds, the light bar beside AC goes off and only the light bar beside AUTO remains.

- This means that the refrigerator is operating on AC electric.

- If 120 volts AC is not available to the refrigerator:

- The light bar beside AC also shows in the center display.

- After a few seconds, the light bar beside AC goes off and the light bar beside LP GAS shows.

- After 10 seconds, the light bar beside LP GAS goes off and only the light bar beside AUTO remains.

- This means that the refrigerator is operating on propane gas.

Backup operating system:

This refrigerator has a backup operating system. The backup operating system allows the refigerator to continue to cool if the temperature sensor of the refrigerator should fail.

If this failure occurs:

- The refrigerator automatically changes to the backup operating system.

- When you push the TEMP SET button, the temperature setting flashes in the center display for ten seconds.

- After the temperature setting flashes, the mode of operation appears in the center dispaly.

- The backup operating system can overfreeze or thaw the contents of the freezer and the fresh food compartment.

Keep in mind the following electrical precautions for DC operation of the refrigerator:

- Good battery condition is necessary for correct DC operation.

- The capacity of the battery charging system must be more than what is necessary for the refrigerator and other DC appliances.

- While the vehicle engine is running, make sure the voltage of the DC power supply leads at the refrigerator is more than 11.5 VDC.

DC Operation Guidelines (3-way models only)

- Make sure the temperatures of the freezer and the fresh food compartment are satisfactory.

NOTE: If you open the door(s) too often, the tempera-

- Have the refrigerator serviced by your dealer or an Norcold authorized Service Center as soon as possible.

tures inside the freezer and fresh food compartment do not become stable. Allow the refrigerator to operate for about one hour after each adjustment change before you examine the contents. The number “9” is the coldest temperature setting.

- If the temperature is too warm, push and hold the TEMP SET button to raise the temperature setting by one number.

- If the temperature is too cold, push and hold the TEMP SET button to lower the temperature setting by one number.

DC Operation Precautions (3-way models only)

For the refrigerator to operate correctly on DC power, the battery must be maintained in a fully charged condition.

For the battery to be fully charged at all times during refrigerator operation on DC, the vehicle engine battery charging system must be in good operating condition.

must be running and the

DC operation is intended only to maintain the temperature of the refrigerator and its contents when they are already cool.

The DC operation is not intended for the initial start up and cooling of the refrigerator. Always use either the AC operation or propane gas operation to initially start up and cool the refrigerator. The refrigerator must be cooled and the temperature must be steady before you operate the refrigerator on DC.

Keep in mind the following guidelines for DC operation of the refrigerator:

- Use DC operation of the refrigerator while the vehicle is in transit.

- Do not use DC operation until the refrigerator and its contents are completely cooled.

- Only use DC operation if the vehicle battery and battery charging system are in good operating condition.

Effects of High Altitude on Prop ane Gas Operation

When you operate the refrigerator on propane gas at altitudes higher than 5500 feet above sea level:

- You may experience reduced cooling performance of the refrigerator.

Refrigerator Care Checklist

- Put the drain hose into a half-gallon or larger container to capture water.

Your refrigerator will give you years of trouble free service if you do these simple checks every three to six months:

- Keep the food compartment and the freezer clean. See “Cleaning”.

- Defrost the refrigerator as necessary. See “Defrosting”.

- Make sure the door seals correctly. See “Door Sealing“.

- Be aware of any cooling changes that are not because of weather, loading, or gas control changes. If changes occur, contact your dealer or an authorized Norcold Service Center.

- Make sure the gas supply is propane gas only and not butane or a butane mixture.

Defrosting

The cooling fins of the refrigerator operate at below freezing temperature and will naturally form frost from humidity, which is always present in the air. The humidity inside the refrigerator increases:

- with higher outside temperature and humidity.

- with the storage of non-sealed fresh foods or warm foods.

- with the amount of time that the door(s) are open.

- with any air leakage into the refrigerator.

It is normal for frost to collect inside the freezer. Excess frost decreases the cooling performance of the refrigerator. Defrost the refrigerator and freezer as necessary:

- Remove all food from the refrigerator.

- Turn the refrigerator OFF.

NOTE: Defrosting the refrigerator makes excess water inside

the refrigerator.

- Remove the drain hose from the drip cup at the rear of the refrigerator.

- Put dry towels (etc.) inside the refrigerator and freezer to absorb melted frost.

CAUTION: High temperatures can cause the inside

surfaces of the refrigerator to warp or melt. Do not use pans of HOT water, a hair dryer, or any other high temperature devices to defrost the refrigerator. Do not use any hard or sharp objects to remove frost. Damage to the interior of the refrigerator can occur.

- To increase the speed of defrosting, put pans of WARM water in the refrigerator and freezer.
