Page 3: Hydrofluorocarbons
E2630-HFC Rev 23.03.2021 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) R 1234ez, 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 E2630-HFC Rev 23.03.2021 asphyxiation in confined spaces. At higher temperatures (>250°C) decomposition products may include hydrofluoric acid (HF) and carbonyl halides. An escape of refrigerant through a leak may damage the refrigerating facilities.

E2630-HFC Rev 23.03.2021 Connections 1. Unscrew four lid screws and detach the lid from the device; 2. Attach the device to the wall using provided screws through the side mounting holes or key slots (This step may be done before step 1, consider your convenience). -
Page 10: Operation
E2630-HFC Rev 23.03.2021 Operation During the first ca. 60 seconds after powering on E2630 performs a warming-up and self-diagnostic routine, indicated by the flashing of each LED. The upper dual-color LED remains continuously green in normal operation and blinks red in case of device or sensor fault. -
Page 11: Sensor Probe Handling
E2630-HFC Rev 23.03.2021 Sensor probe handling The sensor probes of all types are equipped with a hydrophobic microporous PTFE filter to protect the sensor from dust, dirt, and water drops. The filter may be replaced if it gets strongly contaminated. To replace the PTFE filter, unscrew the sensor head cap and remove the old filter. -
Page 12: Maintenance
Calibration E2630-HFC detectors have been calibrated by the Manufacturer with standard gas mixtures before delivery. Provided that the sensor is used under moderate conditions, field recalibration is recommended every 12 months Please contact your dealer for more information. -
