Hi to everyone, and Merry Christmas to all. Thank you for allowing me into your great site. This is my first post. A little info about me: just out of technical college and starting in the refrigeration business. Live and work in the Republic of Panama, Central America.
I need to determine if an old and very uncared for 15HP condensing hermetic is still operational. It has dual high-low pressure control, demand cooling control and oil pressure control. What should be the correct way of servicing this controls: the demand cooling seems to be electronic but the other are 100% mechanical devices with springs, levers, rods, etc. Contact cleaner? WD-40?
Thank you for any comments.
