Wood's Refrigerator Model# R12WRRCC which way to turn the dial to make it warmer

[Idona]

Hi
I have a Wood's Refrigerator Model# R12WRRCC. Refrig: R134a. It belongs to my landlord. I cannot tell which way to turn the dial to make it warmer / cooler. There are no instructions. I am writing because my 12 lb turkey hasn't started thawing yet. I had this problem before. Can you help, please? Right now the dial is set at '2'
Thank you,
Idona

Lower number is warmer.
