Using the length arbitrary interception, directly connected to the 220V power supply through the switch, without the thermostat to control the temperature.
Note: Be sure to close the pipe, no gap (through the air can not play a role in insulation) outside can be used or no longer need to add insulation cotton, depending on the situation.
Can overlap and intersect. Its maximum temperature is only 70°C.
Single motor moisture-proof heating belt, installed at the end of the drive winding of the motor, double motor moisture-proof heating belt, one installed at the drive end, the other installed at the non-drive end, do not overlap around the stator, tie with polyurethane tape, its leads are fixed in the junction box, and finally the dipping paint drying is completed.
