Commercial Refrigeration Installation and Maintenance

Commercial refrigeration installation and maintenance are two intertwined processes that directly define a unit’s efficiency, lifespan, and safety. The three main stages of commercial refrigeration installation must be handled for seamless HVAC integration, proper fitting of the unit in accordance with guidelines, and increased efficiency through proper ventilation and ergonomic design.

During the pre-installation stage, consider the installation site, the type of equipment, and the installation regulations. Carry out the installation on your own or with the help of professionals by following the right steps and using the right tools.

Common challenges with commercial refrigeration installation, such as temperature fluctuations and noise, can be resolved through proper staff training or expert services. Once the installation is complete, an initial setup followed by thorough testing and calibration will kickstart your journey.

Maintenance ensures its reliable continuity while installation sets the scene for smooth operations. Preventing unexpected breakdowns and protecting your investment in the refrigeration unit can be relatively easy if you carry out daily, weekly, and monthly cleaning and maintenance runs and take care of each major component individually.

Contact professional technicians in case of major issues while you independently carry out non-hazardous and simple repairs. By implementing cleaning and maintenance protocols and longevity strategies, you can elongate your unit’s lifespan and maximize your investment. Consider health and safety practices during your operations and look for signs that it is time to upgrade or retrofit your unit.

Pre-Installation Considerations

Before the installation, you should consider the state of the installation site, the refrigeration system you choose, and the regulations and codes you must follow during and after installation. Checking these three boxes in advance will ensure a smoother installation process and save you money.

Site Evaluation and Preparation

The first step of any commercial refrigeration installation is site evaluation and preparation. Professionals will need to evaluate your space based on four main considerations to ensure the safety and longevity of your equipment.

• Plumbing and Ventilation: HVAC integration of the unit is not an easy process, but it can be made easier if the electrical connections and plumbing network are considered prior to purchase and installation. Depending on your unit’s size and necessities, the infrastructure’s placement and capacity might need rearrangement and strengthening. The site can be prepared for installation, making the process smoother if these points are assessed in advance.

• Foundational Strength: Commercial refrigerators and freezers are quite massive and heavy. Walk-in units require an even and strong floor for installation. Depending on the size and intended location of your unit, the site of installation might require additional reinforcements and flooring to prevent cracking, dents, and even collapsing.

• Size and Shape: The size and shape of the site area directly define the unit size you invest in. Commercial refrigerators are required to be placed 4″ (10.16 cm) off the walls to allow for proper ventilation. Take its measurements and subtract 4″ (10.16 cm) on all sides to determine the maximum size of the unit you purchase if you have allocated the space for the unit in advance. You can get it shaped and sized based on your available space to maximize efficiency if you plan to get a custom unit.

• Workflow: Depending on the area of use, take workflow into consideration. Restaurant or hotel kitchens are fast-paced settings where access to the refrigerator should be unobstructed and intuitive. Opt for undercounter units for prep tables and reach-ins next to counters. Considering your workflow before installation ensures your operation’s fastness is optimized. Choosing the right space ensures that the refrigeration unit isn’t sharing door-swing allowance space with other machinery or occupying foot traffic areas for customers. This creates a more comfortable user experience and makes installation less of a nuisance for the staff.

Choosing the Right System

Choosing the right refrigeration system helps you satisfy the demands of your business model. Be aware of the available models, the necessities your business presents, the amount of space and budget you have, and the installation and maintenance challenges associated with each system before proceeding with your purchase.

The most preferred systems include ice machines, walk-ins, reach-ins, undercounter refrigeration units, and display cabinets.

• Ice Machines: Ice machines provide a constant supply of ice for various establishments. They come in various models such as undercounter, countertop, and floor models. Undercounter and countertop models yield less ice than others, combining the production and dispenser functions in one body. They are great for fast-paced environments with low ice demand. Their installation is often easy, thanks to their small bodies. Floored models are the largest and the most industrial options. You need to integrate them into your water system to supply them with water for ice.

• Walk-in Refrigeration: Walk-in coolers and freezers are the largest refrigeration systems. You can get a combo unit that unites the freezing and cooling abilities in one unit or buy separate units depending on your needs. Having two separate units for the job requires double the space. The installation of walk-ins is more complicated than other systems. They require a full HVAC integration on top of electric and plumbing integration. They require a strong foundation and enough room for installation. Walk-ins could disrupt your operations significantly if they break down and require maintenance. The repair team will need space to carry out repairs.
  
  
• Reach-in Refrigeration: Reach-in models are very convenient and quick to use. They are easier to install and maintain. They need to be integrated into the building’s infrastructure, and thanks to their relatively small size, they can be maintained without disrupting the workflow.
  
  
• Undercounter Refrigeration: Undercounter units are placed under the counter. They offer efficient space use and are great for small establishments. While installing these models, keep them as far away from high-temperature equipment as possible to prevent their negative impact.  
  
  
• Display Cabinets: Display cabinets are like reach-in models in terms of their function. They are equipped with glass doors to allow customers and staff to see the unit’s interior without opening it. This feature prevents unnecessary temperature loss and makes browsing easier. While installing these models, you should handle the glass components carefully. Even though they are resistant to breaking and manufactured for frequent use, they still could shatter if not transported and taken care of properly.

Regulatory and Safety Compliance

Before you carry out installations, professionally or DIY, you must be aware of regulations and safety compliances to ensure your process and end result are up to code and ready to pass inspections with flying colors. Codes and regulations change from state to state, so it is always a good idea to consult your local government bodies or suppliers to find out about the specifications of your region. These codes are in place to ensure the safety and health of the public as well as the staff. Not adhering to such rules could cost you a hefty fine or even lead to the temporary or permanent closure of your business, depending on the severity of the non-compliance in question.

Installation Process

The installation process of a commercial refrigeration system can be summed up in 12 skeletal steps. Before you undertake such a project, ensure that you have the necessary tools or directly contact an expert to do it for you.

Step-by-Step Installation Guide

There are 12 main steps to commercial refrigeration installation.

1. Assess the Available Space: Carefully measure the space you allocated for the unit and check to see if the ground is level and strong enough to withstand the weight of the intended unit. If you have no means to reinforce the ground, you will be restricted to the amount your space can shoulder in terms of weight.

2. Choose the Right Unit Size and Model: Choose the right model and size for your unit. The size will inevitably be dictated by the space you can use without sacrificing necessary clearances. The unit’s model could be in terms of its type, such as undercounter, reach-in, walk-in, etc., or terms of its condenser placement. Remote condensers are ideal for small spaces, while others are more convenient for maintenance runs.

3. Prep the Installation Site: Level and reinforce the ground if necessary to prepare the site for the unit’s weight. Examine the wiring and plumbing around the space to see if any adjustments are necessary.

4. Carry Out Necessary HVAC, Plumbing, and Electric Adjustments: Rearrange the current electric lines and plumbing system placement or extend them to accommodate this new addition to their workload if they are incompatible or sufficient with the unit. Such infrastructure adjustments extend the installation time since the walls must be removed to reveal the current state for interference. Additionally, units will need to be integrated into the ventilation system of your space. HVAC integration must be done by an HVAC technician according to the law.

5. Ensure Clearance on All Sides: Leave a 4″ (10.16 cm) off clearance on all sides to allow for proper ventilation and operations because commercial refrigeration units are required. Leave enough swing allowance for the door if your unit has a swing door.

6. Check the Components List: Make sure to verify that all components and parts are delivered and that all tools needed for installation are at hand after prepping the side and receiving your order.  

7. Floor Installation: Install the floorboards if your unit has a floor. If you buy a floorless unit, ensure the ground is level, strong, and non-porous to prevent air leaks, cracks, and mold growth.

8. Threshold Bar Installation: Install the threshold bar before the door itself to ensure a snug fit and prevent air leaks.

9. Wall Panels Installation: Begin by positioning the wall panels in place. Ensure that they are aligned properly and securely fastened to prevent leaks. Wall panels typically interlock to provide stability and insulation, so ensure the seams are tight to prevent air leaks and ensure energy efficiency. Secure each panel to the floor or threshold bar.

10. Door Installation: Install the door into the frame, ensuring it is level and properly aligned. The door should open and close smoothly without any obstruction. Make sure to leave clearance around it if it is a swing door, . Proper door installation is crucial to maintaining the refrigeration unit’s temperature. Check the seals around the door to make sure they are tight and free from gaps, as this will prevent warm air from entering the unit.

11. Ceiling Installation: The ceiling panels can be installed once the walls and door are in place. Check the seals and points of contact carefully to prevent gaps.

12. Test Run: Once all is done, run your unit empty to test it. Check for leaks or similar problems before you start using it fully. An empty test run will signal installation mistakes early on and not endanger your products.

Common Challenges and Solutions

Infrastructural adjustments, space constraints, and non-compliance with local codes and regulations are 3 common challenges associated with commercial refrigeration installations. These challenges can be resolved through careful assessment and preparation in advance. Neglect of consideration on these three fronts could cost you your entire investment, reduce your workflow efficiency significantly, and lead to fines or the closure of your business.

Infrastructural Adjustments

Commercial refrigeration units require complex electrical connections, plumbing adjustments, and HVAC integration. Some adjustments and improvements are inevitable if your infrastructure is not already perfectly aligned with the unit’s needs. The electric supply might not be sufficient, plumbing pipes might not be placed conveniently for drainage and water supply, and the ventilation system might not extend to the area you allocated for the refrigeration unit. Such issues, if not spotted and taken care of early on, can lead to electrical hazards, plumbing issues like inefficient drainage or contaminated water supply, dangerous exposure to coolant chemicals, and loss of cool air due to the lack of proper ventilation.

To get ahead of such hazardous possibilities, you should seek professional help to prep the site’s infrastructure for the installation. You are legally obligated to hire an HVAC technician and should not engage with electrical rewiring or adjustment of plumbing if you aren’t experienced in these fields. 

Space Constraints

Commercial kitchens are filled with large industrial-grade machinery. Commercial refrigeration units are no exception; they might even be the largest equipment you purchase for your space. Spatial constraints are a common challenge faced by business owners. If the available space is not measured precisely, with necessary allowances and clearances in mind, the unit might not fit or obstruct other machinery, resulting in an inefficient workspace.

In such a situation, your only options would be to either pay for a costly adjustment to the unit or the space or replace the unit with one that will fit. Since such “solutions” are not ideal, we recommend measuring your space carefully in advance and only investing in a unit that will surely fit without obstructing other machines or the staff’s foot traffic. 

Non-Compliance

Lack of awareness of local requirements and regulations for commercial refrigeration installation, especially if the installation is done DIY, could result in fines, health hazards, machine failure, staff safety threats, and even closure of your establishment. Find out about local codes and regulations in advance to avoid penalties if you are doing the installation yourself. If you seek professional help, make sure to work with reputable services that are experienced in commercial refrigeration installation in your area.

Post-Installation

After successfully installing your unit, you need to do two things to ensure everything is in order and that the unit does not fail shortly after installation: initial setup, testing, and calibration. These steps kickstart your unit and let you catch mishaps, if there are any, early on without endangering your products. 

Initial Setup and Testing

Once the installation is complete, the initial setup and testing phase begins. You can follow these simple 5 steps to test the unit:

• Start by connecting the refrigeration unit to the power supply and verify that it powers on correctly.
  
  
• Set the desired temperature according to the manufacturer’s specifications and intent of use and allow the unit to reach this temperature.
  
  
• Monitor the unit closely during cooling to ensure its cooling mechanism operates smoothly.
  
  
• Check for unusual noises or vibrations and verify that all fans and compressors function correctly.
  
  
• Inspect all connections, including electrical and refrigerant lines, for leaks or loose fittings. Use leak detectors or monitor the fluctuations in temperature to achieve this.

Calibration

Proper calibration is vital to ensure that your refrigeration unit maintains accurate temperatures, which is crucial for the safety of your products and energy efficiency. The desired temperatures vary based on the unit in question and the products that will be stored. Remember, you cannot use a cooler as a freezer by simply turning down the temperature.

Once you determine the needed temperature for the product you wish to store, turn the unit on and set the temperature. In your first use, check and track the unit’s temperature readings with a reliable external thermometer to ensure that the unit’s internal thermostat is functioning correctly. Adjust the thermostat settings accordingly if there are discrepancies.

In addition to temperature calibration, calibrate any other controls and sensors to ensure they are operating within the recommended parameters. Regular calibration checks should be part of your ongoing maintenance routine to account for any shifts in performance over time. Calibrations might include setting humidity, temperature, and similar thresholds to trigger alarms in case of malfunctions or adjusting the sensors for doors and lights to create a safe, efficient work environment.

Routine Maintenance

Carrying out regular maintenance is the easiest way to prevent unexpected breakdowns or extend the lifespan of your unit. Categorize the maintenance tasks as daily, weekly, and monthly. Such categorization reduces the time you need to dedicate to maintenance and cleaning on a daily basis and makes it easier to spot potential issues in a timely manner, thanks to the periodical nature of check-ups.

Prepare cleaning protocols to train your staff, protect your machinery from rough chemicals, and keep the unit clean from dust and debris that could interfere with its functions. Such cleaning protocols should include component-specific care. For instance, filters used in drains and vents will need more frequent care and replacement than other components. Regularly taking care of individual components ensures the longevity of the whole.

• Electrical Glitches: Power shutting off, even briefly, could endanger the whole unit. Check the power source and the plug first to see if the issue stems from a simple overlook. If that is not the case, hire an electrician to inspect the electric lines around the unit.

DIY Repairs vs. Professional Help

DIY repairs can be done if the issue is not complex, hazardous, or requires expertise. For instance, repairs such as tightening gaskets around the door to reinforce the seals can be carried out easily and don’t harm your health. Taking matters into your own hands in such simple mishaps will save you money and time.

However, schedule for professional help if the problem is unclear or hazardous. Diagnostics and repairs will take less time once an expert is involved. While such professional services could be costly, acting prudently at this stage could cost you more in the long run by endangering the entirety of the unit. Topping up the refrigerant, readjusting the wiring or the plumbing, replacing components of the cooling mechanism, and similar operations will require an expert’s touch. Assess your situation well, and do not try to DIY the repairs if you aren’t %100 confident of your abilities.

Health and Safety Practices

Commercial refrigeration systems store delicate products, mostly food or medicine, that have direct implications for public health and safety. You have a responsibility to your staff and customers to maintain a clean and safe unit for your operations.

Handling Refrigerants

Refrigerants are chemical cooling agents that are used in refrigeration units to achieve the cooling effect. They require careful handling since they can be highly flammable, harmful to the ozone layer, and dangerous to breathe in high doses. You are required by law to hire experienced professionals to handle refrigerant gases.

Regularly check the refrigerant levels to ensure that they are not too high or too low. Lack of sufficient refrigerant will lead the unit to overheat as it attempts to cool without the necessary agent. Fluctuations in the unit’s temperature could indicate a problem with the refrigerant levels.

Avoiding Contamination

Avoid contamination in your unit by following these 4 principles:

• Do not store products such as meat that could drip onto other products on higher shelves.
  
• Clean up spills and drips immediately.
  
• Create zones within the unit, especially if it is a walk-in, to separate allergens from the rest.
  
• Use covered containers to properly separate products.
