6 Technical description
6.1 Description
The refrigerator is an absorption refrigerator. The refrigerator is designed to operate
with different types of power and can be run on an AC power supply, a DC power
supply or with liquefied universal LPG gas. For DC operation, the vehicle battery can
be used. The thermostatic control ensures that the refrigerator temperature is kept
constant and as little power as possible is consumed.
For ignition, the device does three attempts to ignite the flame for a period of
30 seconds at two minutes interval (if flame does not ignite, see chapter “Troubleshooting” on page 38).
The refrigerator is equipped with an automatic safety device which automatically
terminates the gas supply to the burner approximately 30 seconds after the flame
goes out and remains out.
The refrigerator has a manual power mode selection and an automatic operating
mode which selects the most economical power mode connected.
