361929_0917_BA_SM_V4_06.09.2017_U_enUS_CD.docx
►The device must only be installed in well-ventilated areas.
►Do not install the device in cellars or lowered areas.
►Channels and wall penetrations must be sealed underneath and behind the device, in accordance
with fire protection laws.
•Fluid refrigerant causes frostbite on the skin.

•To accelerate the defrosting process, do not use any mechanical devices or other means (e.g. ice scrapers).
•Do not damage the refrigerant circuit.
►Do not expose the device during storage and transport to temperatures higher than 70°C
(158°F).
►Avoid transmission of pulsations and vibrations to the device.
►Avoid external force upon the device such as careless movements with floor trucks or floor c
leaning machines.
►Drilling or other work on the device is not permitted.
