Unifrost R710SVN: How to Use and Maintain Your Commercial Upright Refrigerator

The Unifrost R710SVN is a large-capacity commercial upright refrigerator designed for busy restaurants, hotels, cafés and professional kitchens. With 670 litres of storage capacity, GN 2/1 compatibility, ventilated cooling and a stainless-steel construction, it is built to handle the demands of a commercial environment.

Like any commercial refrigeration unit, getting the best performance from your R710SVN depends on using it correctly and carrying out regular maintenance.

In this guide, we explain how to use, clean and maintain your Unifrost R710SVN to help keep it operating efficiently.

How to use the Unifrost R710SVN

1. Allow the refrigerator to reach temperature

Before loading the refrigerator with food, allow it to reach its operating temperature.

The R710SVN has a temperature range of approximately 0°C to +8°C, controlled through its digital temperature controller.

Avoid filling the cabinet immediately after switching it on. Giving the refrigerator time to cool down first helps ensure that food is stored at the correct temperature.

2. Load the refrigerator correctly

The R710SVN is compatible with GN 2/1 containers, making it suitable for storing large quantities of ingredients.

When loading the refrigerator:

• Avoid overloading the shelves.
• Leave space between products to allow cold air to circulate.
• Avoid blocking air vents.
• Do not place hot food directly into the refrigerator.
• Keep raw and ready-to-eat foods appropriately separated.

Good organisation not only helps maintain an even temperature but also makes ingredients easier to locate during busy service periods.

3. Keep the door closed

Commercial refrigerators can lose a significant amount of cold air every time the door is opened.

The R710SVN features an auto-closing door, helping prevent the door from being accidentally left open. However, staff should still make a habit of closing the door immediately after removing or storing ingredients.

Try to avoid repeatedly opening the door when it is not necessary.

4. Check the temperature regularly

The digital controller makes it easy to monitor the refrigerator's operating temperature.

Check the display regularly and investigate any unusual temperature changes.

A refrigerator that suddenly becomes warmer than normal may have an issue with airflow, the door seal, condenser cleanliness or the refrigeration system itself.

How to clean the Unifrost R710SVN

Regular cleaning is essential in any professional kitchen. It helps maintain hygiene, prevents unpleasant odours and allows you to identify potential problems before they become more serious.

1. Switch off the refrigerator

Before carrying out any cleaning or maintenance, switch off and isolate the refrigerator from the electrical supply where appropriate.

Do not carry out maintenance on an electrically powered appliance.

2. Remove food and shelving

Remove the products from the refrigerator and place them in suitable temperature-controlled storage.

Remove shelves and containers where possible and clean them separately.

3. Clean the interior

The R710SVN has a stainless-steel interior, making it well suited to regular commercial cleaning.

Use a suitable food-safe cleaning product and wipe down:

• Internal walls
• Shelves
• Floor of the cabinet
• Door
• Door seal

Remove any food spills as soon as possible rather than allowing them to dry onto the surfaces.

After cleaning, rinse or wipe away any remaining cleaning product as appropriate and dry the surfaces thoroughly.

4. Clean the door seal

The door gasket is one of the most important components for maintaining a good seal.

Wipe the gasket regularly and check it for:

• Cracks
• Tears
• Dirt or food debris
• Sections becoming detached
• Areas where the seal no longer sits correctly

A damaged or poorly sealing gasket can allow warm air into the refrigerator and make the compressor work harder.

The R710SVN uses a push-fit door seal, making replacement easier when the gasket eventually needs to be changed. It is recommended that the door seal is changed every 2-3 years

How to maintain the condenser

One of the most important maintenance jobs on any commercial refrigerator is keeping the condenser clean.

Dust and grease can accumulate around the condenser over time, particularly in a busy commercial kitchen. This can restrict heat transfer and force the refrigeration system to work harder.

How to clean the condenser

1. Switch off and isolate the refrigerator.
2. Access the condenser in accordance with the manufacturer's instructions.
3. Remove accumulated dust and debris using a soft brush or suitable vacuum.
4. Be careful not to bend or damage the condenser fins.
5. Ensure ventilation openings are not blocked.
6. Once cleaning is complete, reconnect the refrigerator and allow it to return to its normal operating temperature.

The frequency of condenser cleaning will depend on the kitchen environment. A busy kitchen with high levels of dust or grease may require more frequent cleaning.

How to maintain good airflow

The R710SVN uses ventilated cooling, which circulates cold air throughout the cabinet.

To maintain good airflow:

Don't overfill the refrigerator.
Products packed too tightly together can restrict the circulation of cold air.

Keep air outlets clear.
Avoid placing containers directly in front of ventilation points.

Allow space around products.
A little space between containers can make a significant difference to airflow.

Good airflow helps the refrigerator maintain a more consistent temperature throughout the cabinet.

How often should you maintain your R710SVN?

A simple maintenance routine can help prevent problems before they affect your kitchen.

Daily

Check the temperature and make sure the door is closing properly.

Clean up spills and remove any food debris.

Weekly

Clean internal surfaces and shelving.

Inspect the door gasket for dirt or damage.

Check that the refrigerator isn't being overloaded.

Monthly

Inspect the condenser and ventilation areas and clean them where necessary.

Check that airflow around the refrigerator is not being restricted.

Periodically

Arrange professional servicing and have the refrigeration system inspected by a suitably qualified technician where required.

The exact maintenance frequency should always follow the manufacturer's recommendations and the conditions in which the appliance operates.

Troubleshooting common problems

The refrigerator isn't cold enough

First check that:

• The door is closing properly.
• The refrigerator isn't overloaded.
• Air vents aren't blocked.
• The condenser is clean.
• The temperature controller is set correctly.

If the problem persists, professional technical assistance may be required.

The refrigerator is running constantly

A refrigerator may run for extended periods during busy service or when large quantities of food are being loaded.

However, continuous operation can also indicate:

• A dirty condenser
• Poor door sealing
• Restricted airflow
• Excessive ambient temperature
• A refrigeration fault

Carry out the basic checks above before arranging a service call.

There is excessive ice or frost

Check that the door is sealing correctly and that it isn't being left open for extended periods.

The R710SVN features automatic defrost, so persistent or unusual ice accumulation should be investigated.
