Step-by-step instructions
Introduction
We are pleased that you have chosen this refrigerator and hope you will derive much satisfaction from using it.
The refrigerator is designed for storage of foods and storage of frozen foods and making ice.
The installation and servicing should only be carried out by an authorized/qualified person and conform to all relevant local authorities.
It is important to read through these instructions carefully before using the refrigerator. To ensure good refrigeration and economical operation, the refrigerator must be installed and used as described in these instructions.
Follow the instructions in this manual. The refrigerator is quality guaranteed. However, we are not responsible for any failures caused by improper adjustments and unfavourable installation conditions. Please contact service point or distributor service dept. for assistance.
Data plate
Check the data plate, located inside the refrigerator, to ensure that you have received the right model and that it is suitable for the available gas supply and pressure.
The right gas pressure is . . . . . . . . . . . . . . . . . . 2.72 kPa The right voltage is . . . . . . . . . . . . . . . . . . 230 - 240 volt The right gas consumption is . . . . . . . . . . . . . . 1.24 MJ/h
The data plate contains e. g. the following details:
Model designation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Absorption refrigerator system
In an absorption refrigerator system, ammonia is liquefied in the finned condenser coil at the top rear of the refrigerator. The liquid ammonia then flows into the evaporator (inside the freezer section) and is exposed to a circulating flow of hydrogen gas, which causes the ammonia to evaporate, creating a cold condition in the freezer.
When starting the refrigerator for the very first time, the cooling cycle may require up to four hours of running time before the cooling unit is fully operational.
The tubing in the evaporator section is specifically sloped to provide a continuous movement of liquid ammonia, flowing downward by gravity through this section.
If the refrigerator is operated when it is not level and the vehicle is not moving, liquid ammonia will accumulate in sections of the evaporator tubing. This will slow the circulation of hydrogen and ammonia gas, or in severe cases, completely block it, resulting in a loss of cooling.
Note! Any time the vehicle is parked for several hours with the refrigerator operating, the vehicle must be levelled to prevent this loss of cooling.
When the vehicle is moving, the levelling is not critical, as the rolling and pitching movement of the vehicle will pass to either side of level, keeping the liquid ammonia from accumulating in the evaporator tubing.
General advice and information
•Make sure defrosting is carried out periodically
•The refrigerator should be kept clean and dry with the door left open when it is not to be used for some time.
•Ensure that liquids or items with a strong odour are well packaged.
•Service and maintenance must be done on a regular schedule to keep the refrigerator operating properly, efficiently and safely. The service should be performed by qualified personnel only.
•Avoid spraying water through the refrigerator vents while washing your RV.

WARNING |
The sealed cooling system must not be opened. It contains corroding chemicals under high pressure.
Sodium chromate is used for corrosion protection (less than
2 weight % of the coolant).
Installation instructions
The installation, servicing and gas installation must be performed by an authorised/qualified person. The refrigerator must be installed in accordance with the manufacturers installation instructions, local gas fitting regulations, municipal building codes, electrical wiring regulations, AS5601 “Gas Installations” and any other statutory regulations.
Ventilation requirements
The installation shall be made in such a manner as to separate the combustion system from the living space of the mobile home or recreational vehicle. Proper installation requires one lower fresh air intake and one upper exhaust vent.
We recommend fitting the Dometic ventilation system, which is specially developed by Dometic for this purpose. The ventilation kits must be installed and used without modification.
An opening toward the outside at floor level in the refrigerator compartment must be provided for ventilation of heavier- than-air fuel gases. The lower vent of the recommended kits is provided with proper size openings. The flow of combustion and ventilating air must not be obstructed.
The lower side vent is fitted with a panel, which provides an adequate access opening for ready serviceability of the burner and control manifold of the refrigerator. This should be centred on the back of the refrigerator. For further information contact your dealer or distributor.

Installation instructions
Packaging
The packaging of this appliance is design to withstand the transportation from the factory to the point where it will be installed in the recreational vehicle.
Before starting to install the appliance, please, make sure all parts of the packaging have been removed, so there will not be anything left that may come into contact with heat parts of the appliance or obstruct the combustion exhaust gases or the air movement around the cooling unit.

Installing the refrigerator
•The refrigerator must be level, installed on a solid floor and in a substantial enclosure. With the vehicle carefully leveled, the refrigrigerator should level both ways in the freezer compartment.
•Note! Do not install the appliance directly on carpeting.
Carpeting must be removed or protected by a metal or wood panel beneath the appliance, which extends at least full width and depth of the appliance.
•A wood strip must be in place across the upper opening of the enclosure. The top frame of the refrigerator will be anchored to the wood strip with screws.
•When installing the refrigerator in the enclosure, all areas within the recess in which the refrigerator is installed must be sealed. Make sure that there is a complete seal between the front frame of the refrigerator and the top, sides and bottom of the enclosure. A length of sealing strip is applied to the rear surface of the front frame for this purpose. The sealing should provide a complete isolation of the appliance’s combustion system from the vehicle interior. Note! Be careful not to damage the sealing strip when the refrigerator is put in place.
