How much ventilation is needed to avoid overheating?

Ventilation is about giving the condenser a clear path to pull in cooler air and exhaust hot air.

Practical guidance for Irish kitchens when model-specific clearances are not to hand:

Do not box the unit in. Avoid tight alcoves and fully enclosed carcassing around undercounters and prep units.

Keep the air path open at the grille and at the exhaust side. A “gap” that is blocked by foil, cardboard, bags, or staff belongings behaves like no gap at all.

Leave enough space to clean and service. If you cannot easily remove the grille or reach the condenser area, ventilation is usually inadequate.

For the exact clearance for a specific Unifrost upright, counter, or prep/saladette unit, follow the installation section of that model’s manual rather than guessing.
