Simple maintenance and cleaning procedures can greatly extend the life and efficiency of the commercial refrigerator in your kitchen. Learn what you need to do to keep your fridge serving you and your customers for years to come.
1. Clean the condenser fin and coils regularly to remove the dust and grease build-up that inhibits heat transfer. Dusty condenser coils cause a refrigerator to work harder; which translates into bigger energy bills and a shorter life expectancy for one of the biggest investments in your kitchen. To prevent this from happening, use a vacuum or broom to remove dust build up from the coils every three months. Coil cleaning chemicals, such as ProMagic Coil Cleaner, make the job easier by removing dirt without wiping. Keep refrigerators at least 4" from walls so that air can circulate freely around the condenser coils.
2. Keep the refrigerator level. This helps the doors to fit correctly. If your refrigerator isn't level the doors may not seal as tightly as they're supposed to, providing yet another opportunity for energy loss. Check to see if your fridge is level by placing a carpenter's level on top of your unit. Then, if necessary, adjust the casters by hand or with a wrench until you achieve level. If damaged casters are causing a tilt, call a Serv-U sales representative and ask about ordering a new set.
3. Feel the outside of the refrigerator for cold spots. Cold spots indicate that the insulation has either shifted or is waterlogged and should be adjusted or replaced.
4. Check the gaskets regularly. Clean the gasket with an all-purpose cleaner, and wipe dry. If a piece of paper inserted between the door and frame can be pulled out easily, the gasket is not sealing properly and should be replaced. The gaskets on the refrigerator and freezer doors are designed to seal the cool air in and to keep the warm air out – vital to the efficiency of your operation. So, it's important to make sure that seal is as strong as it should be. Look over the gaskets for spots that are cracked or otherwise damaged. Then, shut a piece of paper in the door, and see if you can pull it out easily (the seal should create resistance). If either test turns up problems, consider ordering replacement gasket from Serv-U.
5. Check the evaporator for frost. Ice build-up robs the evaporator of its effectiveness. Most units have automatic defrosters. They can be reset to defrost after operating hours. Defrost whenever ice buildup exceeds 1/4".
With some instruction, your staff can play a significant role in taking care of your valuable equipment. These simple maintenance tips can save a great deal of money in energy and service bills, help to avoid costly breakdowns during peak business hours, and extend the life of commercial refrigeration units.
