4. Operation 4.1 Power Connection The power must be provided in accordance with the requirements on the equipment nameplate. 1)The power supply must be grounding reliably. 2) Regarding single-phase power recirculating chiller, users need to provide three-pole safety ground with protective grounding. Note: Users should be responsible for electric shock or equipment damage if you don’t connect the power supply as described in 4.1.
Figure 4.2.1 Figure 4.2.2 4.2.2.2 Start Refrigeration System at -80℃ Press power switch, the temperature display window PV, SP will shows (Figure4.2.3). The PV window will shows the actual measured temperature(Figure 4.2.4) after 1s, SV window will shows the previous set temperature (Figure 4.2.4). Users don’t need to set SP temperature.
when the chamber temperature close to room temperature. 4.5 Power Off Please close the cold trap according to below steps to ensure its normal running. Figure 4.5 Power off 5 Protection Function 1)Compressor itself is equipped with thermal protection, its main circuit has circuit breakers. When the compressor temperature is too high or over current, automatically it will be disconnect the power automatically.
