Pump

[paulmatto]

I have inflatable mattress but cannot work out how to deflate it with the electric pump. I can inflate ok. I have lost the instructions.
Thanks

You squeeze the valve or pop off the flap inside with some squeezing!

Maybe you need to set the switch to a different position for deflate , or there is a separate deflate button . Take a close look at all the switches/buttons on the pump .

There is usually a big bung to let air out. Surely you do not pump it out.

I just let one down in France 2 weeks ago. Unwanted obstacle in room where I was staying!
You have to manipulate the valve to pop it open.
