Just had the fridge-freezer delivered and they told me it has to sit for three hours before plugging in "because they don't use CFCs any more."
I knew that CFCs were banned, but I hadn't thought about what replaced them and why it would need so much longer to stand. I know that early fridges used ammonia, have they gone back to using that or is it something else?
Update Got home - fridge appears to be pretty cold, ditto freezer, so presumably working OK. I'll bung some frozen food in a little later, once I've checked the temperature. Now where did I put the freezer thermometer.
later Minus 18 - should be OK.
