Owner’s Manual 4

Operating the Refrigerator Controls

Food compartment:

Start up the refrigerator and let it cool for eight hours before loading with food. If the refrigerator does not start to cool down after about

two hours, contact your dealer or a Norcold authorized service center.

For the best cooling performance:

- 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 forms on the cooling ns:

- Cover all liquids and moist foods.

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

- Do not open the door any longer than necessary.

Ventilation fan:

The refrigerator has a thermostat controlled ventilation fan to move air across the refrigerator cooling system. The fan runs when the

interior temperature of the vehicle is 85° F. or higher.

When leaving the vehicle unattended, it is advisable to leave windows or the roof vents open to help keep the vehicle’s interior

temperature less than 85° F. These temperatures allow the refrigerator to operate efciently, minimize fan operation, and limit the

current draw from the battery.

Controls:

The refrigerator control panel is located above the refrigerator door (See Art02429). Unlike refrigerators with electric controls, this

refrigerator will operate on one energy source, independently of the others.

Gas safety valve ..............................................................91

Thermostat .......................................................................96

Flame indicator ..............................................................217

Selector switch ...............................................................207

The gas safety valve [91] is controlled by a thermocouple that is

located in the burner ame. As long as a ame is present, the

safety valve is open and allows propane gas to ow to the burner.

Any loss of ame (empty gas tank, blow out, etc.) closes the safety

valve and stops the ow of propane gas. During ignition of propane

gas operation, you must hold in the gas safety valve until a ame is

present at the burner.

The thermostat [96] controls the temperature inside the refrigerator during operation in both propane gas and AC modes. You can

change the refrigerator temperature to the desired setting by putting the gas control at any position between “START” and “5”. Position

“5” is the coldest temperature setting.

The selector switch [207] changes the energy source of the refrigerator between propane gas (

), AC electric ( ), DC electric

(

), and OFF ( ).

Art02429

Owner’s Manual 5

The refrigerator has an electronic ignition. When you turn the selector switch to propane gas (

), the electronic ignition begins ignition

by sparking at the burner. The sparking continues until the propane gas has ignited and the thermocouple senses that a ame is

present.

The ame indicator light [217] illuminates when a ame is present at the burner and indicates that the refrigerator is operating on

propane gas.

Ignition - propane gas operation:

During warm and humid weather conditions, operate the refrigerator in either AC mode or DC mode for a minimum of

ve minutes before you try to start up the refrigerator in propane gas mode.

1. Open the valve at the propane gas storage tank.

2. Turn the thermostat to the “START” position.

3. Turn the selector switch to propane gas (

4. Push and hold in the gas safety valve.

- Hold in the gas safety valve until the ame meter illuminates.

- Continue to hold in the gas safety valve for about 15 seconds only.

- Do not hold in the gas safety valve for more than 30 seconds.

Do not hold the gas control in for more than 30 seconds. If there is no ame in this time, wait at

least ve minutes before you try ignition again. If you continue to hold the gas control in, gas will

collect in the burner area. This could cause a re or an explosion and result in dangerous personal

injury or death.

- If the ame meter does not illuminate, release the gas safety valve and turn the selector switch to OFF (

- Wait ve minutes and do Steps 3 and 4 again.

5. Turn the thermostat to the desired temperature setting.

Do a test of the gas safety valve:

With an established ame in propane gas mode:

1. Close the manual gas shutoff valve of the refrigerator.

2. After the ame is extinguished, you should hear a sharp “click” sound within three minutes.

The gas safety valve should close with a sharp “click“ sound.

3. Open the manual gas shutoff valve of the refrigerator.

4. Turn the selector switch to propane gas (

5. Do not push in the gas safety valve. The burner ame should not ignite. This means that the gas safety valve is working correctly.

Start up - AC mode operation:

- Turn the selector switch to AC electric ( )

- Turn the thermostat to the “5” position.

- Allow the refrigerator to operate at this setting for 6- 8 hours before changing to the desired temperature setting.

NOTICE

WARNING

Owner’s Manual 6

Start up - DC mode operation:

- Turn the selector switch to DC electric ( ).

The refrigerator receives its DC power from the 12 volt system of the vehicle; either the vehicle engine battery or an auxiliary (house)

battery. The 12 volt system of the vehicle supplies DC power not only to the refrigerator but also to any other DC appliances of the

vehicle. When operating on DC, the refrigerator has a high current draw and can cause a rapid battery discharge.

DC operation precautions:

This refrigerator is made to operate on DC power while your vehicle is “in transit” and AC power or propane gas sources are not

available. Operate the refrigerator on DC power only when the vehicle engine is running.

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 must be running and the battery

charging system must be in good operating condition.

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, have a qualied service technician make sure the voltage of the DC power supply leads at the

refrigerator is more than 11.5 VDC.

DC operation guidelines:

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.

Shut down:

- Turn the selector switch to OFF ( ).

Effects of High Altitude on Propane Gas Operation

When you operate the refrigerator on propane gas at altitudes higher than 4000 feet above sea level:

- You may experience reduced cooling performance of the refrigerator.

- You may experience burner outages.

To avoid these possible problems, Norcold recommends that you operate the refrigerator on AC or DC when at altitudes higher than

4000 feet above sea level. An optional high altitude vent kit is available through your dealer for propane gas operation at altitudes of up

to 10,000 feet above sea level.

Owner’s Manual 7

Refrigerator Care Checklist

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 thermostat changes. If changes occur, contact your

dealer or service center.

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

- When in propane gas operation, examine the appearance of the ame. See “Gas Flame Inspection”.

- Make sure the air ow through the refrigerator coils and condenser is not blocked or decreased.

- Make sure the area behind the refrigerator is clear. Do not use the area behind the refrigerator for storage of anything, especially

gasoline and other ammable vapors and liquids.

A gas absorption refrigerator is not designed to operate in freezing temperatures. If the refrigerator is not equipped for low temperature

operation, and if the cooling system of the refrigerator is exposed to temperatures of 32° F. or lower for an extended period of time,

the refrigerator operation may be disrupted. The refrigerator operation will resume when the cooling system of the refrigerator warms

sufciently.

If the refrigerator is equipped for low temperature operation, the refrigerator will operate in temperatures down to 0° F.

Disrupted operation of the refrigerator, due to extended exposure to temperatures of 32° F. or lower, and any costs incurred to warm the

cooling system of the refrigerator are not covered by the Norcold limited warranty. Please contact your local RV dealer for information

about how to resume refrigerator operation or about how to equip your refrigerator for operation in freezing temperatures.

Do not change the installation or the venting of your refrigerator. Refrigerator failures, which are the result of changes to either the

refrigerator installation or to the venting, are not covered by the Norcold limited warranty.

Effects of Freezing Temperatures on Refrigerator Operation

Defrosting

The cooling ns 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 is open.

- with any air leakage into the refrigerator.

It is normal for frost to collect inside the refrigerator. Excess frost decreases the cooling performance of the refrigerator. Defrost the

refrigerator as necessary:

- Remove all food from the refrigerator.

- Turn the refrigerator OFF.

Owner’s Manual 8

A good time to clean the refrigerator is just after you defrost it. To avoid food odors, clean the inside of the refrigerator as often as

necessary:

- Remove all food from the refrigerator.

Do not use abrasive cleaners, chemicals, or scouring pads because they can damage the interior of the refrigerator.

- Wash the interior with a solution of dish detergent and warm water.

- Rinse with a solution of baking soda and clean water.

- Dry with clean cloth.

- Put all food in the refrigerator.

Cleaning

Door Sealing

If the door does not seal correctly, excess frost will collect inside the refrigerator. Make sure the door seals correctly:

- Close the door on a piece of paper that is about the size of a dollar bill (See Art00980).

- Gently pull the paper.

- You should feel a slight drag between the door gasket and the cabinet.

- Do this on all four sides of the door.

- If you do not feel drag on the paper, the door gasket is not sealing correctly.

- Contact your dealer or Norcold authorized service center.

Defrosting the refrigerator makes excess water inside the refrigerator.

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

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.

- Remove the wet towels (etc.) and dry the interior.

- Start up the refrigerator.

- Allow the refrigerator to cool down.

- Return all food to the refrigerator.

- Using a wrench, assemble the orice assembly to the burner.

- Assemble the are nut to the orice assembly.

- Tighten the are nut by hand.

- Hold the orice assembly securely and, using a wrench, tighten the are nut 1/4 revolution only.

- Examine the burner box gasket.

- Replace if necessary.

- Attach the burner box to the refrigerator.

- Using a leak test solution, examine the refrigerator ttings for leaks.

- Install the refrigerator.

- Using a leak test solution, examine the propane gas supply lines for leaks at the manual shut off valve.

Remove the Refrigerator

A dealer or Norcold authorized service center must do this procedure.

The rear of the refrigerator has sharp edges and corners. To prevent cuts or abrasions when working on

the refrigerator, be careful and wear cut resistant gloves.

1. Close the valve at the propane gas tank(s).

To avoid possible gas leaks, always use two wrenches to tighten or loosen the gas supply line connections

of the refrigerator.

2. Remove the screws which attach the front of the refrigerator to the enclosure.

3. Move the refrigerator forward enough to disconnect the propane gas supply line from the manual shut off valve, located on top of the

refrigerator.

4. Remove the AC power cord from the receptacle.

5. Remove the DC wiring from the refrigerator.

- Mark the DC wires so you can put them back in the correct location.

6. Remove the exible intake and exhaust pipes from the vent terminal housing.

7. Remove the refrigerator from the enclosure.

CAUTION

NOTICE

WARNING

Owner’s Manual 12

Reinstall the Refrigerator

The rear of the refrigerator has sharp edges and corners. To prevent cuts or abrasions when working on

the refrigerator, be careful and wear cut resistant gloves.

Make sure that the connections of the exible intake and exhaust pipes are completely sealed. Make sure

that the “O” ring seals are not damaged. If the seals are not complete, exhaust fumes can be present in

the living area of the vehicle. The breathing of exhaust fumes can cause dizziness, nausea, or in extreme

cases, death.

1. Attach the exible intake and exhaust pipes to the vent terminal housing.

2. Attach the DC connections to the terminal block.

3. Put the AC power cord into the receptacle.

4. Connect the propane gas supply line to manual shut off valve of the refrigerator.

To avoid possible gas leaks, always use two wrenches to tighten or loosen the propane gas supply line

connections of the refrigerator.

5. Push the refrigerator into the enclosure.

6. Install the screws which attach the front of the refrigerator to the enclosure.

7. Open the valve at the propane gas tank(s).

Do not allow the leak detecting solution to touch the electrical components. Many liquids are electrically

conductive and can cause a shock hazard, electrical shorts, and in some cases, re.

8. Using a leak test solution, examine the propane gas supply lines for leaks.

Refrigeration Failure

If the refrigerator does not cool, it does not mean that the cooling system is defective. Other items which effect the refrigerator

operation may be the cause of the problem.

If you notice a loss of cooling, do a check for a failure of either the electric or propane gas controls as follows:

- Change the energy source of the refrigerator.

- If the refrigerator is operating on propane gas, change it to electric operation.

- If the refrigerator is operating on electric, change it to propane gas operation.

- Operate the refrigerator for several hours.

- Make sure the refrigerator is level within 3° side-to-side and 6° front-to-back.

- Make sure the controls are in the correct position for the energy source in use.

- Make sure the gas pressure is 11 inches Water Column (10.5 inch Water Column min. - 11.5 inch Water Column max.) and the

voltage is 120 volts AC (108 volts min. - 132 volts max.) (on model 323 only, 12 volts DC, 10.5 volts min. - 15.4 volts max.)

- Make sure the air ow through the refrigerator cooling system is not blocked or decreased.

- If no cooling occurs after about eight hours, contact your dealer or a Norcold authorized service center.
