It was very tough to find the actual manual online for your modle in English. However, you can call Delonghi customer support:
DeLonghi Customer Support: (800) 322-3848
Delonghi does have manuals for some models on their site. Take a look at this link, the model might be similar enough to yours to be able to get the information you need.

Hope this was helpful.

Depending on handy you are, the power cords for heaters can be replaced, but may require soldering or other electrical and mechanical skills. You MUST replace the cord with one that has the same amperage and heat ratings.....that goes for the plug too.

If it is a Ksd31 thermostat you need, you are in luck. I found what I needed for my model 5600/7 on ebay. The store Larksining sells the for as few as five/pkg in various temp. settings. I got 5 ea. in two temp settings for less than $11.00 USD with shipping from Hong Kong.
