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 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 ame. See “Gas Flame Appearance”.
- Make sure the air ow in the lower intake vent, through the refrigerator coils and condenser, 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 anything, especially
gasoline and other ammable vapors and liquids.
Temperature Control System
Although the refrigerator is not frost -free, it is made to limit frost on the cooling ns. At regular intervals, the temperature control
system automatically melts most of the frost from the cooling ns. The water from the cooling ns 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.
E󰀨ects of High Altitude on Propane 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.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that you operate the refrigerator on AC when at altitudes higher than 5500 feet
above sea level.
E󰀨ects of Freezing Temperatures on Refrigerator Operation
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
su󰀩ciently.
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.
Refrigerator Care Checklist

Installation and Owner’s Manual 9
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(s) are open.
- with any air leakage into the refrigerator.
Although the refrigerator is not frost -free, it is made to limit frost on the cooling ns. At regular intervals, the temperature control system
automatically melts most of the frost from the cooling ns. The water from the cooling ns 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.
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.
Defrosting the refrigerator makes excess water inside the refrigerator.
- Remove the drain hose from the drip cup at the rear of the refrigerator.
- Put the drain hose into a half-gallon or larger container to capture water.
- Put dry towels (etc.) inside the refrigerator and freezer 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, 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.
- Remove the wet towels (etc.) and dry the interior.
- Remove the drain hose from the large container and put the drain hose back into the drip cup.
- Remove the large container from the enclosure.
- Start up the refrigerator.
- Allow the refrigerator to cool down.
- Return all food to the refrigerator.
NOTICE
CAUTION

NOTICE
Defrosting
Cleaning
A good time to clean the refrigerator is just after you defrost it. Clean the inside of the refrigerator as often as necessary to avoid food
odors:
- 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 mild cleaner or a solution of liquid 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.

WARNING
!
CAUTION
!
- This refrigerator is not approved for use as a free standing refrigerator. It is equipped for the use of propane gas only and
cannot be changed to use any other fuels (natural gas, butane, etc.).
- Incorrect installation, adjustment, alteration, or maintenance of this refrigerator can cause personal injury, property
damage, or both.
- Obey the instructions in this manual to install intake and exhaust vents.
- Do not install the refrigerator directly on carpet. Put the refrigerator on a metal or wood panel that extends the full width
and depth of the refrigerator.
- Do not allow anything to touch the refrigerator cooling system.
- Propane gas can ignite and cause an explosion that can result in property damage, personal injury, or death. Do not
smoke or create sparks. Do not use an open ame to examine the propane gas supply line for leaks. Always use two
wrenches to tighten or loosen the propane gas supply line connections.
- Make sure the electrical installation obeys all applicable codes. See “Certication and Code Requirements” section.
- Do not bypass or change the refrigerator’s electrical components or features.
- Do not spray liquids near electrical outlets, connections, or the refrigerator components. Many liquids are electrically
conductive and can cause a shock hazard, electrical shorts, and in some cases re.
- 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 ame. Do not
bend, drop, weld, move, drill, puncture, or hit the cooling system.
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.
WARNING

Installation and Owner’s Manual 17
Certication and Code Requirements
This refrigerator is certied by CSA International as meeting the
latest edition of ANSI Z21.19 / CSA 1.4 standards for installation
in mobile homes or recreational vehicles.
The refrigerator must be installed in accordance with this
“Installation Manual” in order for the Norcold limited warranty
to be in e󰀨ect. In addition, the installation must conform to the
following, as applicable:
In the United States and Canada:
- Local codes, or in the absence of local codes, the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, the Natural Gas and Propane installation Code, CSA B149.1, ANSI A119.2 Recreational
Vehicles Code, and CSA Z240 RV Series, Recreational Vehicles.
- A manufactured home (mobile home) installation must conform with the Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280 [formerly the Federal Standard for Mobile Home Construction and Safety, Title 24 (part 280), and the
current CSA Z240.4, Gas-equipped Recreational Vehicles and Mobile Housing.
- If an external power source is utilized, the appliance, when installed, must be electrically grounded in accordance with local codes
or, in the absence of local codes, the National Electrical code, and ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2.
Parts 1 and 2.
All propane gas supply piping and ttings must obey local, state, and national codes about type and size. These components must also
obey the current NFPA 1192 section 2-4, and in Canada with the current CAN 1-6.10 Standard.
Art01290
Ventilation Requirements
The completed installation must:
- Make sure there is su󰀩cient 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 ue 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 ba󰀪es
and panel construction.
Certied installation needs one lower intake vent and one upper exhaust vent. Install the vents exactly as written in this manual. Any
other installation method voids both the certication 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
oor level. This allows any leaking propane gas to escape to the outside and not to collect at oor level.
CSA International certication allows the refrigerator to have zero (0) inch minimum clearance at the sides, rear, top, and bottom. While
there are no maximum clearances specied for certication, the following maximum clearances are necessary for correct refrigerator
performance:
Bottom 0 inch min. 0 inch max.
Each Side 0 inch min 1/2 inch max.
Top 0 inch min. 1/4 inch max.
Rear 0 inch min. 1 inch max.
WARNING
!

Installation and Owner’s Manual 18
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 vent, goes up around the refrigerator coils where it removes the excess heat from the refrigerator components, and
goes out through the upper vent. If this air ow is blocked or decreased, the refrigerator will not cool correctly.
Each NORCOLD model is certied by CSA International for correct ventilation. Install only the certied vents that are listed in this
manual.

- The oor must be metal or a wood panel and extend the full width and depth of the
enclosure.
- The oor must be able to support the weight of the refrigerator and its contents.
- The Minimum distance between the bottom of the enclosure and the oor is 12mm.
(N4141Only)
3. Make sure there are no adjacent heat sources such as a furnace vent, a hot
water heater vent, etc.
4. If there is more than 1/2 inch between either side of the refrigerator and the
inside of the enclosure:
- Fill the space with berglass insulation or add a ba󰀪e to eliminate the excess
clearance.
- Make sure that the batt-type insulation extends from the enclosure face, to the
combustion seal at the rear of the refrigerator cabinet.
- Securely attach the batt-type insulation to the enclosure so that it remains in this
position during refrigerator installation, if it becomes wet, and in windy conditions.

Make sure that no sawdust, insulation, or other
construction debris is on the refrigerator or in the
enclosure. Debris can cause a combustion hazard and
prevent the refrigerator from operating correctly.
Tighten the screws of the upper roof exhaust cap to 10 inch-
pounds max. Also make sure that the air ow around the upper
roof exhaust cap is not blocked or decreased by other roof
mounted features such as a luggage carrier, an air conditioner, a
solar panel, etc.
- If the design of the vehicle allows, install the roof exhaust vent [12] directly
above the condenser [11] of the refrigerator (See Art02337):
