It is very important to practice preventative maintenance on your cooling systems to help prevent them from clogging or breaking down, which could lead to spoiled food, rotten food, etc. The following guidelines are provided from Heatcraft’s Operation & Instruction Manual.

At every six month interval, or sooner if local conditions cause clogging or fouling of air passages through the finned surface, the following items should be checked.
1) Visually inspect unit
• Look for signs of corrosion on fins, cabinet, copper tubing and solder joints.
