Installation instructions

Connections

LP gas connection

The gas installation and servicing must be carried out by an authorised person and conform to all relevant local authori- ties.

The refrigerator is not designed for operation on town gas or natural gas but for operation on LP gas, the pressure of which must be 2,72 kPa for Propane. Check that this is stated on the data plate. The gas supply system must incorporate an approved gas pressure regulator to maintain a supply pressure of 2,7 kPa.

CAUTION

Check that the gas supplied to the refrigerator is at the correct pressure.

Hook up to the gas supply line is accomplished at the manual gas valve, which is furnished with a ISO 7/1 -Rp 1/8 internal pipe thread connection. All completed connections should be checked for leaks with soapy water.

!

WARNING

Do not use an open flame to check for gas leaks.

The gas supply system must incorporate an approved gas pressure regulator to maintain a supply pressure of 2,72 kPa .

When testing the gas supply system at test pressures in excess of 1/2 psi, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing the gas supply system at pressures less than or equal to 1/2 psi, the appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve.

If detailed instructions on the installation and connection to the gas supply are required, contact your dealer or distributor.

Testing LP gas safety shut off

The gas safety shut off must be tested after the refrigerator is connected to the LP gas supply.

To test the gas safety shutoff, proceed as follows:

1.Start the refrigerator and check that the gas flame is lit. This can be observed on the flame indicator E. The red indicator is in the green field (ON).

2.Close the gas valve by turning knob A back to “OFF” position.

3.Wait for one minute.

4.Remove protection cover.

5.Open the gas valve by turning knob A to position “GAS” without pressing buttons C and D.

6.Apply a non-corrosive commercial bubble solution to the burner jet. Be careful not to damage the burner jet.

7.No bubbles should appear at the opening of the burner jet. The presence of bubbles indicates a de- fective gas safety shutoff, and service is required. If no bubbles were present at the burner jet, the gas safety valve is working properly.

8.Rinse jet thoroughly with fresh water before pro- ceeding. Be careful not to damage the burner jet.

9.Replace the protection cover and turn the main switch OFF and back ON.

10.Normal operation of the burner should return.

Allow the burner to operate for a minimum of 5 minutes.

Electrical connection

230-240 V AC connection

The electrical installation must be carried out in a proper and durable manner, taking into account all relevant regulations and codes of practice.

Check that the voltage stated on the data plate is the same as the main voltage in use (230-240 V). Electrical leads must be routed and secured so that they cannot come into contact with hot or sharp parts of the refrigerator.

For mains voltage operation, it is important that the cir- cuit to and in the caravan is effectively earthed.

The refrigerator is equipped with a three-prong (grounding) plug for your protection against shock hazards and should be plugged directly into a properly grounded threeprong receptacle. Note! Do not cut or remove the grounding prong from this plug.

The free length of the cord is 6 ft. (1,8 m). It is recommended the receptacle placed on the left side of the refrigerator (viewed from the rear) and approximately 150 mm from the floor. This will allow easy accessibility through the vent door.

230-240 VAC receptacle

150 mm

Exchange of supply cord

The cord should be routed to avoid direct contact with the burner cover, flue cover or any other components that could damage the cord insulation. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
