Installation and Owner’s Manual 3
The thermostat [96] (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.
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.
- Keep the refrigerator full.
Do a test of the gas safety valve:
With an established ame in GAS mode:
1. Close the manual gas shutoff valve [218] of the refrigerator
(See Art01254].
2. After the ame is extinguished, you should hear a sharp “click”
sound within three minutes.
NOTE: The gas safety valve should close with a sharp “click“
sound.
- Put foods that are more likely to freeze on the lower shelf.
The selector switch [207] changes the energy source of the
refrigerator between propane gas ( ), AC electric ( ), DC
electric ( ), and OFF ( ).
The gas safety valve [91] is built into the control panel. As long
as a ame is present, the valve is open and allows propane gas
to ow into the burner. Any loss of ame (empty gas tank, blow
out, etc.) closes the safety valve and stops the ow of gas.
The piezo igniter [216] makes a spark which ignites the ame in
the burner.
The ame meter [217] shows if a ame is present in the burner.
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 ve seconds:
WARNING: Do not hold in the safety valve 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 in the safety valve, gas will collect in the burner
area. This could cause a re or explosion and result in
dangerous personal injury or death.
- When a ame is present and the ame meter moves into the
green area, release the safety valve.
- If the ame meter does not move into the green area, do this
step again.
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 ame 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.
- Turn the selector switch to the AC position ( ).
- Turn the thermostat to the temperature setting that you wish.
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 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.
5. Turn the thermostat to the temperature setting that you wish.
Installation and Owner’s Manual 4
- 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 qualied 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.
- 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.
Defrosting
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 the OFF position ( ).
Effects 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.
Refrigerator Care Checklist
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.
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.
NOTE: Defrosting the refrigerator makes excess water inside
the refrigerator.
- Put dry towels (etc.) inside the refrigerator 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.
- Remove the wet towels (etc.) and dry the interior.
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“.
- Start up the refrigerator.
- Allow the refrigerator to cool down.
- Return all food to the refrigerator.
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:
Installation and Owner’s Manual 5

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.
- 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.
Installation and Owner’s Manual 10
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 501C section 2-4, and in
Canada with the current CAN 1-6.10 Standard.
Ventilation Requirements
WARNING: The completed installation must:
Assemble the Enclosure
1. Make sure the enclosure is 29.75 - 29.88 inches high x 20.50
- 20.63 inches wide x 21.38 inches deep.
2. Make sure the oor is solid and level.
- The oor must be metal or a wood panel and extend the full
width and depth of the enclosure.
- Make sure there is sufcient 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
bafes and panel construction.
Certied 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
certication 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 certication allows the refrigerator to have
zero (0) inch minimum clearance at the sides, rear, top, and
bottom. While there are no maximum clearances specied for
certication, the following maximum clearances are necessary for
correct refrigerator performance:
Bottom 0 inch min. 0 inch max.
Each Side 0 inch min 1/4 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 ow is blocked or decreased, the refrigerator will
not cool correctly.
- The oor must be able to support the weight of the
refrigerator and its contents.
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 (batt-type) insulation or add a
bafe to eliminate the clearance.
- The rear of the batt-type insulation must be between 14
-15 inches from the face of the enclosure.
- 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.
Install the Lower and Upper Vents
1. Using the following chart, decide which vents and rough
opening (RO) sizes to use.
Certied Vent P/N RO Height RO Width
Upper Roof 622293 24 in. 5 1/4 in.
Exhaust Vent
Upper Side 617485 7 1/4 in. 18 in.
Exhaust Vent
Lower Side 617484 9 3/4 in. 19 3/8 in.
Intake Vent
Universal Upper 620505 6 3/16 in. 17 15/16 in.
and Lower Vent
2. Install the lower intake vent (See Art01629):
NOTE: The lower intake vent is also the service access opening
for the components on the rear of the refrigerator.
Each NORCOLD model is certied by CSA International for
correct ventilation. Install only the certied vents that are listed in
this manual.
