Shanghai Haozhuang Instrument Co., Ltd. developed the LNB brand low temperature thermostat. Energy saving and environmental protection, leading domestic. Professional manufacturing is more secure and affordable Use and maintenance: 1. The air-cooled low-temperature constant-temperature bath unit depends on the correct rotation of the fan. For example, the forward rotation can be started and the reverse rotation means that the power wiring is reversed. It needs to be replaced before starting. 2. The setting values ​​of the various protection devices of the unit have been debugged by Shanghai Haozhuang Experimental Instrument Manufacturer. Users should not modify them at will. 3. When the unit fails to alarm and shut down, first press the unit's stop button (the alarm light will go out), and then check the cause of the failure, and it is forbidden to start the machine forcibly before the failure is eliminated. 4. The unit should not be shut down by cutting off the main power supply unless it is an emergency; if the unit is not used for a long time in winter, the unit should be shut down first, then the main power supply, and the water in the system. 5. To keep the machine room clean and well ventilated, regularly clean and decontaminate the condenser to ensure the normal and stable operation of the unit. 6. For the air-cooled low-temperature constant-temperature bath, please keep the surface of the cooling coil of the low-temperature constant-temperature bath clean to ensure that the surrounding air is circulated and the temperature is low. Regularly clean the deposits on the coil to ensure a good heat exchange effect. Haozhuang brand series low temperature thermostats are air-cooled low temperature thermostats. 7. If the low temperature thermostat has been used for more than six months, or the high and low pressure switches often fail, or the cooling capacity is reduced, please arrange for the staff to clean the condenser. If the repair is carried out as described above for many times, and there is a long beeping sound of the cryostat malfunction, the professional technicians of cryostat must be repaired.
