About Your Refrigerator
Storage Volume:
This refrigerator is made to store fresh and frozen foods and for making ice.
Gross capacity 181 Liter
Leveling:
CAUTION: The refrigerator is made to operate within 3° 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.
Operation during travel:
While the refrigerator should be level when the vehicle is stopped, performance during travel is not usually effected. Do not operate the
refrigerator on propane gas while travelling. This can reduce performance, cause an unstable ame, or extinguish the ame.
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 an authorized Thetford 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 ns:
- 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.
Crisper(s):
The crisper(s) are located at the bottom of the fresh food compartment and supply a storage
area to preserve fruit and vegetable freshness. Make sure that you always push the crispers
fully in.
NOTE: Do not wash the crispers in a dishwasher. The crispers are not dishwasher
safe.
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.

Adjustable shelves:
The shelves in the freezer and the fresh food compartment are made so you can remove them or move them.
To remove or move the shelf of the freezer:
- Pull the shelf forward out of the slot.
- Push it fully into the slot that you wish.
To remove or move each shelf of the fresh food compartment:
- Remove the screw from the retainer of each shelf at the rear of the refrigerator.
- Pull each shelf forward out of the slot.
- Push each shelf fully into the slot that you wish.
- Attach the retainer with the screw.
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 handles:
During travel, the door latch prevents the door from opening. When closing each door, push the door toward the refrigerator until you
hear a “click” sound.
To open each door, pull the handle away from the refrigerator.
During storage, the storage latch prevents the door from completely closing. Use it to prevent
odors when the refrigerator is stored for an extended period of time.
To operate the storage latch (see Art00991), open each door about 13 mm and push the
storage latch [55] into the cutout [56] of the strike plate. Do not use the storage latch as a
travel latch because the doors will not be fully closed.

Control panel (See Art02257):
The thermostat [96] is the temperature control of the refrigerator. Number 1 is the
warmest temperature setting and number 5 is the coldest temperature setting.
NOTE: If the cooling load changes, you must manually change the thermostat to
maintain the same temperature inside the refrigerator.
When the outside air temperature is below 10° C, 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.
- Put foods that are more likely to freeze on the lower shelf.
Art01869
Installation /Owner’s Manual 5
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 propane gas tank, blow out, etc.) closes the safety
valve and stops the ow of propane 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.
The moisture reduction heater switch [253] operates a heater that prevents moisture from forming on the center divider between the
doors of the freezer and the fresh food compartment. The moisture reduction heater requires DC current to run. Before turning on the
heater, make sure that the refrigerator is connected to DC power and that the vehicle battery has sufcient capacity. The current draw
of the heater is 0.258A at 12V. The heater will not operate if the switch is turned off.
The cooling system ventilation switch [252] operates a fan on the rear of the refrigerator. Use this fan to improve the refrigerator cooling
performance when the ambient temperature is above 38° C. The fan is controlled by a thermostat when the switch is on, so it will run
only intermittently, when temperatures are high enough. The cooling system ventilation fan requires DC current to run. Before turning
on the fan, make sure that the refrigerator is connected to DC power, and that the vehicle battery has sufcient capacity. Current draw
when the fan is running is 0.430A at12V. The fan will not run if the switch is turned off, regardless of temperatures.

Ignition - propane gas operation:
1. Open the valve at the propane 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, wait about ve seconds and release the safety valve.
- If the ame 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 ame in GAS mode:
1. Close the manual gas shutoff valve [218] of the refrigerator (See Art02258).
2. After the ame is extinguished, you should hear a sharp “click” sound within 90
seconds.
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 ame should not ignite. This means that the gas safety
valve is working correctly.

Start up - AC operation:
- Make sure that 240 volts AC is available.
- Turn the selector switch to the AC position ( ).
- Turn the thermostat to the temperature setting (numbers 2 -5) that you wish.
NOTE: In AC operation only, the number 1 setting of the thermostat turns the refrigerator off.
Start up - DC operation:
- Make sure that 12 volts DC is available.
- Turn the selector switch to the DC position ( ).
Shut down:
- Turn the selector switch to the OFF 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.
- 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 11.5VDC.
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.
Effects of High Altitude on Propane Gas Operation
When you operate the refrigerator on propane gas at altitudes higher than 1.7 km above sea level:
- You may experience reduced cooling performance of the refrigerator.
- You may experience burner outages.
To avoid these possible problems, Thetford recommends that you operate the refrigerator on AC when at altitudes higher than 1.7km
above sea level.

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 gas control changes. If changes occur, contact your
dealer or an authorized Thetford 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 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 materials or
combustible materials, especially gasoline and other ammable vapors and liquids.
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(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 the drain hose into a two liter or larger container to capture water.
- 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.
- 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.
Installation / Owner’s Manual 8
- Remove the large container from the enclosure.
Art00980
- 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:
- Remove all food from the refrigerator.
NOTE: 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 liquid dish detergent and warm water.
- Rinse with a solution of baking soda and clean water.
- Dry with a clean cloth.
- Put all food in the refrigerator.

- Push the drip tray back into the slots in the refrigerator cabinet.
- Push the drip tray back into the drain hose.
- Put the wire shelf back in the original position.
Door Sealing
Check the seal of the doors.
If either door does not seal correctly, excess frost will collect inside the refrigerator. Make sure the doors seal correctly (See Art00980):
- Close each door on a piece of paper that is about the size and thickness of a dollar bill.
- Gently pull the paper.
- You should feel a slight drag between the gasket and the cabinet.
- Do this on all four sides of the door.
- If you do not feel a slight drag on the
paper, the door does not seal correctly.
- Have your dealer or an authorized Thetford Service Center correct the seal of the
door.
