Technical description

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 “Trouble-shooting” on. 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. The refrigerator is equipped with an cold weather/low ambient control, which allows the refrigerator to operate in low ambient temperatures for a longer time.
