Feb 22, 2014 #1 Hi everyone, Just wondering if anyone has an original manual for an Engel Fridge model MRFT-540C-G4 that they could scan and send me a. "/>. On average, a family refrigerator uses 15 amps to start up. The older 39 litre engles draw 4.5 amps. Engel fridge/freezers run on battery power (12v/24v dc) or 110v/120v ac, so whether youre on the road, on the water or safe at home, you can use your engel to make life a little easier.
