This refrigerator is made to store fresh and frozen foods and for
making ice.
Total capacity 2.7 cubic feet
Freezer capacity .4 cubic feet
Food compartment capacity 2.3 cubic feet
Leveling:
CAUTION:
off level side-to-side and 6° off level front-to-back (as
looking at the front of the refrigerator). Operating it at
more than these limits can cause damage to the cooling
system and create a risk of personal injury or property
damage. Make sure the vehicle is level before you
operate the refrigerator.
The refrigerator is made to operate within 3°
Food compartment:
Ignite or 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 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.
Installation and Owner’s Manual 4
Page 5
Freezer compartment:
- Put foods that are more likely to freeze on the upper shelf.
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.
Operation during travel:
While the refrigerator should be level when the vehicle is
stopped, performance during travel is not usually effected.
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 [1] is between the ribs
[2] of the latch plate [3].
Ignition and Start Up
The selector switch [2] changes the energy source of the
refrigerator between propane gas (
electric (
The gas safety valve [3] is built into the control panel. As long
as a flame is present, the valve is open and allows propane
gas to flow into the burner. Any loss of flame (empty gas tank,
blow out, etc.) closes the safety valve and stops the flow of gas.
The piezo igniter [4] makes a spark which ignites the flame in
the burner.
The flame meter [5] shows if a flame is present in the burner.
), and OFF ( ).
), AC electric ( ), DC
Ignition - propane gas operation:
1. Open the valve at the gas storage tank.
2. Turn the thermostat to the 5 position.
3. Turn the selector switch to the propane gas position (
4. Push and hold in the safety valve and push in the igniter
several times in rapid succession, for about five seconds:
).
WARNING: Do not hold in the safety valve for more
than 30 seconds. If there is no flame in this time, wait at
least five minutes before you try ignition again. If you
continue to hold in the safety valve, gas will collect in the
burner area. This could cause a fire or explosion and
result in dangerous personal injury or death.

The thermostat [1] (See Art00976) changes the amount of
propane gas that goes to the burner. This acts as the temperature control of the refrigerator. Number 5 is the coldest temperature setting.
NOTE: This is not an automatic gas control. It does not change
the flame from high fire to low fire as do some RV
refrigerators. If the cooling load changes, you must
manually change the gas control to maintain the same
temperature inside the refrigerator.
When the outside air temperature is below 50° F, the refrigerator may have a tendency to freeze food at the colder temperature settings. To reduce the tendency to freeze food:
- Turn the thermostat to a warmer temperature setting.
- When a flame is present and the flame meter moves into
the green area, release the safety valve.
- If the flame meter does not move into the green area, do
this step again.
5. Turn the thermostat to the temperature setting that you wish.
Do a test of the gas safety valve:
With an established flame in GAS mode:
1. Close the manual gas shutoff valve [2] of the refrigerator
(See Art01254].
2. After the flame is extinguished, you should hear a sharp
“click” sound within three minutes.
NOTE: The gas safety valve should close with a sharp “click“
sound.
3. Open the manual gas shutoff valve of the refrigerator.
4. Without pushing in the gas control, push the igniter several
times rapidly in succession. The burner flame should not
ignite. This means that the gas safety valve is working
correctly.
Start up - AC operation:
- Make sure that 120 volts AC is available.
- Keep the refrigerator full.
- Turn the selector switch to the AC position (
- Turn the thermostat to the temperature setting that you
wish.
Installation and Owner’s Manual 5
).
Page 6
Start up - DC operation (3-way models only):
- Make sure that 12 volts DC is available.
- Turn the selector switch to the DC position (
).
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
be in good operating condition.
must be running and the alternator must
- Be aware of any cooling changes that are not because of
weather, loading, or gas control changes. If changes occur,
contact your dealer or service center.
- Make sure the gas supply is propane gas only and not
butane or a butane mixture.
- When in propane gas operation, examine the appearance
of the flame. See “Gas Flame Appearance”.
- Make sure the air flow in the lower intake vent, through the
refrigerator condenser and coils and out the upper exhaust
vent 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 any
combustible materials, especially gasoline and other
flammable vapors and liquids.
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 qualified 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.
Shut down:
- Turn the selector switch to the OFF position ( ).
Defrosting and Cleaning
Defrosting:
It is normal for frost to collect on the cooling fins inside the
refrigerator. Excess frost decreases the cooling performance of
the refrigerator. Defrost the refrigerator as necessary:
- Turn the selector switch to the OFF position (
- Remove all food from the refrigerator.
NOTE: Defrosting the refrigerator makes excess water inside
the refrigerator.
- Put dry towels (etc.) inside the refrigerator to absorb the
water.
- Put trays of hot water in the freezer until the frost is melted.
- Empty the drip tray.
- Remove the wet towels (etc.) and dry the interior.
- Put the drip tray and all food in the refrigerator.

- The refrigerator cooling system is under pressure. Do not
try to repair or to recharge a defective cooling system.
The cooling system contains sodium chromate. The
breathing of certain chromium compounds can cause
cancer. The cooling system contents can cause severe
skin and eye burns, and can ignite and burn with an
intense flame. Do not bend, drop, weld, move, drill,
puncture, or hit the cooling system.
All gas supply piping and fittings must obey local, state, and
national codes about type and size. These components must
also obey the current NFPA 501C section 2-4, and in Canada,
the current CAN 1-6.10 Standard.
Ventilation Requirement s
CAUTION:
- The rear of the refrigerator has sharp edges and corners.
To prevent cuts or abrasions when working on the
refrigerator, use caution and wear cut resistant gloves.
Certification and Code Requirements
This refrigerator is certified under the latest edition of ANSI
Z21.19 Standards by the American Gas Association for installation in mobile homes or recreational vehicles and is approved by
the Canadian Gas Association.
The installation must obey these standards and this “Installation
Manual” for the NORCOLD limited warranty to be in effect.
Installation must agree with local codes. In the absence of local
codes, the installation must obey these standards:
In the United States:
- National Fuel Gas Code, ANSI Z223.1.
- Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 32-80.
- Standard for Recreational Vehicles, RVIA A119.2 latest
edition.
- For installations which need an electric outlet that is
energized by an external power source, the refrigerator
must be electrically grounded as writen in local or state
codes, the National Electrical code, and ANSI/NFPA 70.
In Canada:
- Current CGA B149.1 and CGA B149.2 Installation code for
Propane Appliances and Equipment.
- Current CSA Z240.4.2 Installation Requirement for Propane
Appliances and Equipment in Recreational Vehicles.
- Current CSA Z240.6.2/C22.2 No. 148 Electrical
Requirement for Recreational Vehicles.
WARNING: The completed installation must:
- Make sure there is sufficient intake of fresh air for
combustion.
- Make sure the living space is completely isolated from
the combustion system of the refrigerator.
- Make sure there is complete and unrestricted ventilation of the flue exhaust which, in gas mode, can
produce carbon monoxide. The breathing of carbon
monoxide fumes can cause dizziness, nausea, or in
extreme cases, death.
- Make sure the refrigerator is completely isolated from
its heat generating components through the correct use
of baffles and panel construction.
Certified installation needs one lower intake vent and one upper
exhaust vent. Install the upper exhaust vent either through the
roof or through the side wall of the vehicle exactly as written in
this manual. Any other installation method voids both the
certification and the factory warranty of the refrigerator.
The bottom of the opening for the lower intake vent, which is
also the service access door, must be even with or immediately
below the floor level. This allows any leaking propane gas to
escape to the outside and not to collect at floor level.
American Gas Association/Canadian Gas Association (AGA/
CGA) certification allows the refrigerator to have zero (0) inch
minimum clearance at the sides, rear, top, and bottom. While
there are no maximum clearances specified for certification, the
following maximum clearances are necessary for correct
refrigeration:
Bottom 0 inch min. 0 inch max.
Each Side 0 inch min 1/8 inch max.
Top 0 inch min. 1/4 inch max.
Rear 0 inch min. 1 inch max.
These clearances plus the lower and upper vents cause the
natural air draft that is necessary for good refrigeration. Cooler
air comes in through the lower intake vent, goes up around the
refrigerator coils where it removes the excess heat from the
refrigerator components, and goes out through the upper
exhaust vent. If this air flow is blocked or decreased, the
refrigerator will not cool correctly.
Each NORCOLD model is certified by AGA and CGA for correct
ventilation.
- When installed, the refrigerator must be electrically
grounded as written in the local or state codes, and the
Canadian Electrical Code C22.2. Parts 1 and 2.

DC Operation 12 volts DC voltage
(3-way models only) (11.5 volts min. - 15.4 volts max.)
Current Draw 12 Amps at 12 Volts DC
This refrigerator operates on both AC and DC electrical
sources. Operation out of these limits may damage the
refrigerator’s electrical circuit parts and will void the warranty.
Connect the 120 volts AC supply:
WARNING:
grounded three-prong receptacle. Do not remove the
round ground prong from the power cord. Do not use a
two-prong adapter or an extension cord. Operation of the
refrigerator without correct ground can cause dangerous
electrical shock or death if you are touching the metal
parts of the refrigerator.
Put the AC power cord into a grounded three-prong receptacle:
- Make sure the receptacle is positioned within easy reach of
the lower intake vent.
- Make sure the power cord does not touch the burner cover,
the flue pipe, or any hot component that could damage the
insulation of the power cord.
Connect the 12 volts DC supply (3-way models only):
As the distance from the vehicle battery to the refrigerator
increases, the correct AWG wire size and fuse size also
increases. If the wire size is too small for the distance, a
voltage drop occurs. The voltage drop decreases the output of
the system heater and causes decreased cooling performance.
WARNING: A circuit overload can result if the wires and/
or fuses are not the correct size. Refer to your local
codes or the applicable RVIA Standards for the correct
wire and fuse sizes.
1. For the best performance, Norcold recommends that you
use the following wire and fuse sizes:
- Measure the distance from the vehicle battery to the
refrigerator:
(108 volts min. - 132 volts max.)
1.5 Amps at 120 Volts AC
14 Amps at 14 Volts DC
Connect the AC power cord only to a
- If the distance is 0 - 20 feet, use #12 AWG min. wire
size and a 20 amp max. fuse.
- If the distance is over 20 feet, use #10 AWG min. wire
size and a 30 amp max. fuse.
The wire connections must be clean, tight and free of
corrosion. If any of these items are not correct:
- A voltage drop to the refrigerator will occur.
- The voltage drop will reduce the cooling performance of the
refrigerator.
The terminals for connecting the DC power supply are marked
positive (+) and negative (-) on the terminal block of the refrigerator. Make sure that:
- Each DC power supply wire is attached to the correct
polarity terminal.
- The chassis or the vehicle frame is not used as one of the
conductors.
- The DC power supply wires including the fuses are routed
directly from the battery to the refrigerator.
2. Connect the D.C. power supply wires:
- Attach a 1/4 inch Quick Connect terminal to each DC power
supply wire.
- Push each power wire onto the terminal block [1] at the rear
of the refrigerator (See Art00975).
- Make sure each DC power supply wire is on the correct
polarity terminal.

use a 3/8” SAE (UNF5/8 -18) female flare fitting as the
connection to the refrigerator.
- Put the gas supply line up through the floor of the enclosure
and in a manner to prevent vibration and abrasion.
- Make sure the hole through the floor is large enough to
allow clearance for the gas supply line.
- Put a weather resistant seal (grommet, sealant, etc.)
around the gas supply line where it goes through the floor
to prevent vibration and abrasion.
- Attach the gas supply line to the bulkhead fiting [2] of the
refrigerator (See Art01254).
Examine the gas supply system for leaks:
WARNING: 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, fire.
Use a solution of liquid detergent and water to examine the gas
supply line and all gas connections for leaks.
If you use compressed air for the test:
- The pressure at the manual shut off valve of the refrigerator
must not be more than 1/2 psig (14 inches Water Column).
