DC power is not regulated by this thermostat.
Turning off the refrigerator
If the refrigerator is not to be used for a period:
1. Shut off any valve in the gas line to the refrigerator.
2. Empty the refrigerator. Defrost and clean it. It must be completely dry inside to avoid mold growth.
3. Pull out the hook as figs below and secure it to the hole underneath the front cover. This will allow the door to be
open slightly always and get air circulated.
Winter Operation
If the ambient temperature is lower than 10 degrees, the winter cover should be fitted. This will protect the cooling unit
from excessively cold air which might result in too much strong or even poor performance of the unit.
Insert Decor Panel
The doors are designed to accept decorative door panels to match the kitchen décor. The decorative panels must be
4 mm or less in thickness. Door panels should be installed in the refrigerator doors before installing the refrigerator in
the vehicle. The door panel dimensions for XCD-90B are 19.1"(485±0.5mm) wide by 26.3"(670±0.5mm) high.
To install the door panels, first pull the panel retainer off the bottom of the door by removing two screws. Push the
door panel into the slots of the door and put the panel retainer back into place to hold the panel inside the door. See

to the battery. Simply replace the battery with a new one and put the cover back.
Fig 1 Fig 2 Fig3
The lighting in the cabinet (Fig 3)
The lighting of this refrigerator uses LED, which is with high brightness, no heat emission and long service life, and
the light switch is controlled by the door, which means the inside light will start illuminating automatically when the
door is opened. Please pay attention that if there is malfunction with the light, please contact the after-sales service
department of this product or professionals for examination.
Food Storage
The freezer compartment is not intended for quick freezing of foods. It keeps food frozen.
The fresh food compartment stores and cools food. For best cooling performance, air must circulate within the fresh
food compartment. Do not cover the shelves with paper, plastic, etc.
To reduce frost on the cooling fins, cover liquids and moist foods. Do not place hot foods in the compartment, and do
not leave the door open longer than needed.
The door storage areas hold items such as 1.5-liter bottles, pop cans, and other commonly used items.
Allow the refrigerator to cool for 8 hours before loading foods. Loading a warm refrigerator with warm food increases
the cool down period.
Never keep items in the refrigerator which might give off flammable gases.
Never put bottles or cans of fizzy drinks in the frozen food storage compartment as they may burst when freezing.
Also don’t give children ice stuff straight from the frozen food as they could cause frostbite. Most kinds of frozen food
can be stored in the frozen food compartment for about a month. This period of time may vary, however, and it is
important to follow the instructions on the individual packets.
Warning about the use of your refrigerator:
When storing your food, be particularly careful about the special conditions of use of a refrigerator located in a vehicle.
The conditions inside the vehicle change a lot depending on:
- The weather conditions
- The high temperature inside the vehicle especially if the vehicle is parked in the sun. The temperature may then
reach 122°F (50°C).
- The use of the 12 V source during a long trip.
- The refrigerator being located behind a window facing the sun.
- In using the refrigerator too quickly after power-optimal temperature.
Under those circumstances, the refrigerator may not keep the temperature low enough for the food preservation
(especially highly perishable food).
List of highly perishable food: meat, fish, poultry, pork butchery precooked dish and all the products which need to be
stored at 4-6°C max.
11

Always remember:
- Wrap up separately raw food and cooked food in aluminum or plastic wrap.
- Don’t remove the packing if useful information about the product are written on it.
- Don’t leave refrigerated products outside the refrigerator too long.
- Put the products that have to be eaten first in the front of the refrigerator.
- Put left-overs in sealed boxes and eat them rapidly.
- Wash your hands carefully before touching any food and before eating.
- Wash your refrigerator regularly. Use soap and water to wash it.
The use by date appears as follow: “Best before…” followed by the date or the information to know where the date
appears on the labelling.
Ice-Making
Fill the ice tray just below the brim with drinking water and place it on the freezer compartment.
It is possible to make ice faster by turning the control knob temporarily to its highest value but do not forget to turn it
back to its regular setting afterwards as the refrigerator might otherwise become too much cold.
Defrosting
Frost will gradually accumulate on the refrigerating surfaces. It must not be allowed to grow too thick as it acts as
insulation and adversely affects refrigerator performance.
Check the formation of frost regularly every week and when it gets about 3 mm thick, defrost the refrigerator. To
defrost the refrigerator, turn it off and remove the ice tray and all food items.
Warning: normally the temperature of items of frozen foods would rise unduly during defrosting and so they should
be consumed within 24 h or discarded.
Do not try to accelerate defrosting by using any kind of heating appliance, as this might damage the plastic surfaces
of the refrigerator. Neither should any sharp objects be used to scrape off the ice.
The defrost water runs through the drainage pipe to a receptacle at the rear of the refrigerator where it evaporates.
Defrost water in the freezer compartment should be mopped up with a cloth.
When all ice has melted, wipe the refrigerator dry and restart it.
Place the food items back inside but wait until the refrigerator is cold before making ice cubes
Trouble Shooting and Maintenance
If the refrigerator fails to work, check the following points before calling a service technician:
1. That the above installation and operating instructions have been followed.
2. The refrigerator is level.
3. If it is possible to start the refrigerator on any of the connected sources of energy.
4. If the refrigerator fails to work on gas, check:
-That the gas bottle is not empty.
-That all LP-gas valves are open.
5. If the battery ignition fails to spark, replace the battery if necessary.
If the refrigerator is not cold enough it may be because:
1. The ventilation of the cooling unit is inadequate.
2. The thermostat is set on the high temperature position.
3. The doors are opened frequently, or the gasket is not sealed properly.
4. Too much food is put at one time.
5. The gas pressure is incorrect - check the pressure regulator at the gas container.
If the refrigerator still does not work properly, call a service technician.
The sealed cooling system must not be opened, since it contains corroding chemicals under high pressure.
Do not use open flame to check for leakage in the gas tubes!
