Fan coil should be regarded as the most use of it in their lives, the type of fan coil across all sectors, so, for fan coil units, in its safe state, there are a lot of standards is sure to be met. Below, a look at it together. 1, the safety requirements should be consistent with the provisions of fan coil ZBJ72-018 of. 2, connected fan coil electrical lines should be neat, solid, wire through holes and then plug should be insulated tube or other appropriate protective measures. 3, fan coil press at room temperature and normal humidity conditions, with 500V insulation resistance meter Insulation resistance measuring fan coil live parts and between conductive parts and according to the provisions of Table 6 condensate test conditions of continuous operation after 4h with 500V insulation resistance meter Insulation resistance test measured live fan coil portion and the non live parts and conductive parts between its cold and hot insulation resistance value should not be less than 2MΩ. 4, fan coil of electric intensity by each speed level fan coils were placed in the 'on' position, between the live parts and conductive parts to 1500V nominal frequency AC voltage. Voltage application should be less than half the prescribed value, then quickly rise to its full value, continued 1min. At the time of mass production, the available voltage 1800V and 1s time instead. 5, fan coil according to the provisions of the condensed water test conditions, continuous operation after 4h, immediately measure the motor winding temperature resistance method. GBA755 of provisions calculated temperature rise. The method of test strips, the temperature rise of the motor windings comply with the relevant provisions of the corresponding standard motor. 6, fan coil by condensation water test conditions and wiring diagrams 5 continuous operation of the provisions of 4h, then to 110% of rated voltage, leakage current measurement fan coil exposed metal parts of the power lines, the exposed metal parts and leakage current between the power line should not exceed 1.5mA.
