Can you help with instructions for a wax heater?

[Jokat]

Hi, I want to use the Pro Wax 100 and the instructions it comes with are rather minimalistic
The wax comes in a plastic tub and I just don't know whether the whole tub goes into the aluminium bucket that sits in the heater, or whether I'm supposed to scrape it out of the tub in to the bucket. This is what I thought makes most sense, but the wax is so hard and sticky that I can't get it out, even with a metal spoon! Can you tell me what I need to do???
