2 Product description
2.1 General information
AHT products comply with EU Directive 2011/65/EU
(RoHS2) for the prevention of hazardous substances
in electrical and electronic devices and EU
regulation 1907/2006 (REACH) on the registration,
evaluation and approval of chemicals.
In the product design, the manufacturer has
considered the environmental and disposal-
friendliness of the device, in particular, for the
refrigerant propane (R-290) and the propellant
pentane (for the insulating foam). Propane does not
have any ozone depletion potential (ODP) and only
a very low greenhouse potential (GWP) of 3.
The refrigerant R-134a is recorded in the Kyoto
Protocol. It does not have any ozone depletion
potential (ODP) and has a greenhouse potential
(GWP) of 1430.
2.2 Technical data

2.2.1 Power rating plate and serial number
When handling the device, the information on the
"power rating plate" must be observed. This is found
on a sticker at the top right inside of the device cover
and contains important technical data about
- device name and device type,
- serial number,
- Climate class (see → Chapter 2.3),
- Rated voltage and frequency,
- rated current and rated consumption,
- Refrigerant and amount used,
- Net content,
- Date of manufacture,
- Test mark,
- Technical data for the interior lighting (optional),
- and other technical data.
2.3 Intended use
The devices are only suitable for packaged,
refrigerated food products.
NOTICE
• Property damage due to improper use.
► Do not operate the device outside the indicated
climate category conditions (ambient
temperature, relative humidity).
► The ambient temperature must not be less than
16°C (60.8°F).
