Delivery, carrying-in and installation
The unit weighs 288 kg packed. Delivery to your building is included in our offer; carrying the freezer into the laboratory and positioning it need several people and handling equipment, so we quote this separately once we know the route (floor, lift, narrowest door). Plan at least 10–15 cm free space behind and beside the cabinet for ventilation.
