Page 3: Hydrofluorocarbons
E2670-HFC Rev 15.03.2023 Hydrofluorocarbons HFCs are relatively non-flammable, chemically stable, and nonreactive. Classification of halocarbon refrigerants Group Refrigerants Chlorofluorocarbons (CFC) R11, R12 Hydrochlorofluorocarbons R22, R141b, R142b (HCFC) Hydrofluorocarbons (HFC) R32, R125, R134a, R143a Hydrofluoroolefins (HFO) R1234ez, R1234yf, R1336mzz Chlorine-containing refrigerants (CFC and HCFC) are considered to be damaging to the ozone layer and contributing to the greenhouse effect. - Page 4 E2670-HFC Rev 15.03.2023 R410a mixture R32, R125 50:50 −48.5 °C Overexposure may cause dizziness and loss of concentration. At higher concentrations, CNS depression and cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined spaces. At higher temperatures (>250°C) decomposition products may include hydrofluoric acid (HF) and carbonyl halides.

Page 8: Operating Conditions
E2670-HFC Rev 15.03.2023 Operating conditions The device should be used in a basic electromagnetic environment, where the latter is defined in EN 61326-1. Avoid strong mechanical shock and vibrations. Although E2670 series devices are suitable for use in the presence of flammable dust, special precautions should be taken when operating in a dusty environment. - Page 9 E2670-HFC Rev 15.03.2023 The device is fixed on the wall using two fixing holes located outside the sealed area of the device (see dimensional drawing). Unscrew four lid screws and detach the lid from the detector. Fix the detector on the wall and earth the enclosure using an earthing terminal on the side of the device.

Page 13: Correct And Incorrect Cabling For 24 Vac
E2670-HFC Rev 15.03.2023 NOTE! The outputs are not galvanically isolated from the external power supply and share a common 0V. Allowed load resistance limits are stated in the Specifications table. To power the instrument from an external power source, connect terminals 0V and +U to the source. -
Page 14: Operation
E2670-HFC Rev 15.03.2023 Operation Turn on the power. The instrument warm-up time takes about 1 minute after switching on and the final sensor stabilization time to maximum accuracy takes about 30 minutes, but depending on the sensor type, it can take up to several hours. The operating status is indicated by the LED on the PCB of the device. -
