1Applies exclusively to these Installation and Operating Instructions.
2Standard points: Standard refrigeration (NK): L0°/L32° C; deep freezing (TK):
L-20°/L32° C; heat output: heat ow that is given off by the device in cooling mode to the
surroundings.
3 EER: Energy Efciency Ratio; ratio cooling capacity to electric power consumption.the
surroundings.
4Evaporation rate related to normal point L0°/L32°C, 30 % relative room humidity
and operating time 16 h/d. Deviating operating points and reduced running time can
reduce evaporation performance
5 Manufacturer’s data
6A-rated sound pressure level measured at a distance of 1 m. Divergent sound
pressures levels can be reached depending on spatial considerations.
7 Volume ow indicated at the standard point at a ΔT of 6K (NK) or 8K (TK).

16 Warranty
Excerpt from our warranty terms.
The warranty period is 1 year. The warranty claim
period starts on the day of the delivery, which is to be
veried by delivery note or invoice. Malfunctions that
can be attributed to poor workmanship or material
defects will be rectied free of charge within the
warranty period.
Further claims, in particular for consequential
damages, are excluded.
We shall assume no warranty for damages resulting
from improper or inappropriate use, faulty installation
or commissioning by the purchaser or third party,
natural wear and tear, faulty or negligent handling,
chemical or electrochemical and electrical impacts,
provided that they cannot be attributed to our fault,
failure to observe the installation, operating, and
maintenance instructions, improper modications
or repair work by the purchaser or third party, and
effects of parts of external origin.
The warranty shall also expire if the refrigerant
circuit has been opened by unauthorized persons,
interventions in the system structure have been
made, or the serial number on the device has been
changed or made unrecognizable.
