Commercial Refrigeration Guide | Shop-Equip

Set out below are straight forward answers to frequently asked questions about Commercial Refrigeration.

If you have a question not listed here or within our help or policies section, please contact us.

Prior to purchase ensure the dimensions of your new unit fit to the space you have available. Ensure that you can get the unit to its final position and through any doors or restrictions.
Refrigerated units should not be placed adjacent to direct heat sources, i.e. radiators, cookers or even in direct sunlight. Open top displays and multidecks should not be placed in positions where draughts occur.

Food should only be displayed during the working day and placed into chilled storage overnight.

Ideally the serve over cabinet should be turned off overnight or at least on a weekly basis to avoid any build up of ice.

in addition to standalone serve over cabinets, we can also help with Special Counter Installations.

If fitted, nightblinds should be used on multidecks when not in use.

Doors and lids should be kept closed as much as possible and lights in display units turned off when not required.

Rear shutters on ice cream conservators and serve overs should also be closed when not in use to help maintain temperature and reduce energy consumption.

Where applicable, condensors should be kept clean to ensure maximum efficiency and reduce the chance of non-warranty breakdown.

Is there sufficient airflow around the cabinet?

Check the owners' manual for the correct airflow required. Generally, 50 to 75mm (2 to 3 inches) is required around the cabinet to allow sufficient airflow.

Also, check the ambient temperature of your environment. Commercial refrigeration in the UK have a designated Climate Class. This tells you the range of room temperature it is suitable for.

Climate Class 3:

  • Ambient temperature between 10C and  25C with a 60% Relative Humidity (RH). This is applicable to cabinets such as Serve Overs and Multideck Displays.

Climate Class 4:

  • Ambient temperature between 10C and 30C with a 55% Relative Humidity (RH). This is applicable to most cabinets such as refrigerators, integral cold rooms etc.

Climate Class 5:

  • Ambient temperature between 10C and 40C with a 40% Relative Humidity (RH). This is applicable to Tropicalised Cabinets only.

If the ambient temperature is outside of these parameters then your cabinet will not operate correctly.

To ensure smooth operation of your refrigerated cabinet, it is important that you clean the condensors on a regular basis, ideally once a month, as part of your ongoing site maintenance.

  • Switch the cabinet off and locate the condenser.
  • Clean it gently with a soft brush or vacuum attachment.
  • Once clean, Turn the unit on and allow up to half a day to return to the correct temperature.

If after this time the cooler/freezer is still warm, see "How do I adjust the temperature?"

Refer to your owners' manual for instructions on adjusting your thermostat.

If you require assistance, please call the Shop-Equip team on 01623 741 500 during normal office hours.

The unit must be completely level. For the doors to close correctly this must be the case. Use a spirit level and adjust using the feet in the four corners at the base of the unit.

If the unit has sliding doors, check that the door runs at the top and bottom of the doorframe are clear of dirt build-up or obstructions and spray with a water repellent lubricant such as WD40.

If the thermostat is set too low, it can cause excess ice and water to develop.

Generally 3°C is sufficient to cool whatever you store in your cooler and -18°C to -22°C is sufficient for your freezer.

Check that the thermostat is set correctly. (See: how do I adjust the temperature)

Ensure that your unit is plugged directly into the mains and not connected through a mains extension cable.

If fuses still trip, try unplugging a piece of equipment on the same circuit. It could be that by adding another piece of equipment you may be overloading your consumer board.

There are no elements or materials in your refrigerated cabinet that can cause bad odour.

Check for spillage of the product(s) stored in the cooler/freezer eg. Milk, and clean thoroughly.

To prevent drain blockage, flush a cup of water down the drain every 8 weeks.

The light bulb or starter unit are not covered by the warranty, as they are consumable items. However, most DIY stores stock suitable light bulbs.

Condensation can form when the relative humidity is too high. To avoid this, try and increase the ventilation in the premises.

If none of the situations above are applicable to you, make sure you have your model type, serial number and company details at hand.

You will need to contact our Customer Support Team to discuss your situation on 01623 741 500 during normal office hours.
