My kreo optimus came without instrution manual

No manual as such, but instructions are here

http://www.optimusent.com/_windows_5280ass.html

https://www.google.com/search?q=Optimus+F-5286+manual

..

The manual might have the code to adjust the display screen optimus sta-3500 manual on google and on the companies official website too.Or call or email customer service then.

Wondering if you have the correct model number; could it be 85SUFF?

SUFF = Single Under Fryer Filter

The Specification Sheet may be here:

This however does not seem to correspond to available manuals listed here

Suggest you check the the manufactuer's information to verify the model number; should be a plate with the model and serial nunber etc..

Alternatively you could view some of the available manuals to see if one pertains to yours.

You could try

operatingguides.com

if you need a user manual
or

servicemanuals.co.uk

if you want the schematics etc

We've used them in the past and found them very good.

Also if it is not listed then ask via the link and they
will probably be able to get it for you.
