A commercial refrigerator unit is essential to your establishment, cooling all your beverages and ingredients to perfection. That’s why it’s necessary to perform routine Commercial Refrigeration Maintenance on your unit between regular service visits.
The size of the pan in the commercial refrigerator is determined by how much water is created during the defrost cycle. The more water, the more voltage your heating element may need, or the size of the pan might change. Your OEM will most likely be the person to run your system through a defrost cycle and help you determine the size of evaporator pan you will need.
Things to consider when choosing the size of your evaporation pan.
∙ pan size
∙ heating element
∙ refrigerated case size
∙ display case location
∙ display case maintenance
So, what should be done on a regular basis? Mentioned below are some helpful commercial refrigeration tips to maintain the unit by cleaning it and running strong.
1. Regularly Clean the Condenser Coil
It will help if you clean your commercial refrigerator or freezer’s condenser coil routinely. A huge number of manufacturers will recommend you to clean the unit once every three months, and there are many manuals provided specifically with cleaning tips. If dirty or dusty, it will definitely be difficult to maintain the temperature, causing overheating and component failure.
The coil is located exactly near the unit’s condenser. Disconnect the power of the unit, and use a stiff bristle brush to get rid of the dust and dirt. Then, clear out all the remaining remnants with the help of a strong vacuum or even an air compressor.
Check out the guide on cleaning condenser coils, commercial refrigeration condensate pan or your equipment manual for more detailed instructions. Your manual will for sure provide specific degreasing tips, which are crucial if your unit is in a kitchen near fryers or griddles.
2. Consistently Clean the Interior & Exterior
Try to schedule out a thorough cleaning of the entire commercial refrigeration unit on a weekly or even a biweekly basis. Remove the items stored from the interior, and place them in another unit or temporary cooler.
Now scrub the shelves and surface with warm water and soap or a vinegar solution using a soft brush. If it is possible to remove any drawers and shelving, make sure to soak them for a while and rinse when clean.
The exterior of the refrigeration unit also should be cleaned regularly. It’s essential using proper cleaning solutions and materials, especially on a stainless steel exterior. It is ideal to avoid using abrasive scrubbers or sponges as well as chlorine cleaners. Instead, going for a washcloth or even a soft brush to clean the surface.
A combination of warm water and a dash of vinegar or detergent-based solution will work best for the routine maintenance of the unit. If you are looking to remove grease or baked-on food, consider baking soda paste or an appropriate stainless steel degreaser.
3. Check to surround of the Evaporator Coil
As the condenser coil, the evaporator coil is a vital component of your commercial refrigerator. The evaporator coil is just located by the evaporator fan, which is responsible for absorbing heat as warm air passes through the refrigeration system, helping calm the unit’s interior.
It is ideal for making sure to keep the surrounding area near the coil clear and clean consistently. Avoid cramming the interior with a number of items, especially if it is piping hot. Avoid blocking airflow by the vents inside the unit can cause the coil to freeze, leading to water leaks and a rise in cabinet temperature.
4. Often Check the Gaskets
The door gaskets are essential to every commercial refrigeration unit. Any split or crack caused can prevent the door from making them seal shut, which might cause cool air to exit the fridge’s interior. If the door gasket is broken, make sure to replace it with the appropriate manufacturer’s recommendation.
For instance, you must use the gasket associated with your unit’s serial and model number when replacing a True refrigerator gasket.
If there are no splits or cracks, it will turn out well if you still routinely clean the gaskets to prevent them from any damage. This should be done more often if your unit is in a commercial kitchen where grease is regularly used or may be in the supermarket where there are chances of leakage and spilling. Too much grease and dirt can wear out your gaskets over time.
5. Check out the Air Filters
Grease and dust from the restaurant fryers and griddles also can be a hassle on your commercial fridge’s air filters. A significant buildup can prevent air in the unit from ventilating correctly, so that’s why routine cleanings are very important.
Remove any dust or lose debris by using a powerful shop vacuum, and use a degreasing solution to eliminate any thick grease. Consult the unit’s service manual for tips on how to decrease the filter properly.
Too much grease and dust can definitely damage the air filter. If you notice it splits from the debris, make sure to replace the filter immediately.
6. Routinely Clean Drain Pans and Tubes
A large commercial refrigerator or walk- in cooler evaporator can attract a significant amount of sludge or even slime, which can lead your unit to freeze up. You should make sure to check your drain pan and any tubing that is likely to experience frequent buildups.
If the drain pan overflows with moisture and sludge, it can definitely emit a pungent odor throughout your kitchen space. You should clean the pan at least once a month using a vinegar solution or the usage of soap and warm water.
Excess grime causes drain tubes to clog. Try to make sure by checking the tubing every couple of months to prevent a significant blockage. When there is a substantial clog in your drainage hoses, it causes an overflow while defrosting the system that leaks onto your floor.
If you notice any tracing of calcium or water spots on the exterior of the hoses, clean them with soap and water to prevent any future wear.
7. Keep Your Refrigeration Unit Dry
Be sure to wipe clean any form of liquid that accumulates on the shelving or even on the surface of your Reach-In Freezers. Too much moisture or dampness can cause your refrigerator or freezer to freeze up over time. It is wise enough to not only clean up spills immediately, but you also should check for moisture buildups at least once a week.
This maintenance schedule applies to a walk-in unit as well. Removing the liquid and dampness from the floors of your fridge can reduce the number of slips and falls that occur.
