Coldtech, Labtech, General, Coldmatic. No matter the name the m/n is always the same. SCP0100H-WC

Have an customer with these self contained packaged refrigeration units. They sit on top of the walk in cooler. A hole is cut into the top of the walk in to allow the evaporator section hang down into the box. These units can maintain 98.6*f heat with discharge gas, to 40*f cool. Also has a desuperheating valve.
Anyone no where to get an online manual. Yes I've tried searching the web. But not able to find the said m/n.
