It took a couple of minutes to track this down from the site listed in the photo properties .... and then a Google to find the company's website.
What Gordy (pimpthatfood) has posted is a piece of commercial kitchen equipment made in the UK - a Lincat Ltd. OE7702 - Opus 700 series Electric Double Tank Past Boiler,
which can also be used as a steamer or bain marie. At a list price of £2,380.00 it's nice it can be used for more than one thing!
Now, as for your questions about cleaning it, Gordy - this is obviously an alien appliance for most of us. You might want to go to the Lincat Website
... click on the Contact Us
button ... enter the information they want ... then in the section "Details of catering equipment which you intend to purchase in the next 12 months" enter that you need a manual for your pasta cooker or information on how to clean it. That should get you an informed answer.
That's the best answer I can give you ... hope it helps!
