Installation and maintenance
Installation
Install the furnace according to the drawing. Check the heating
element whether there is any phase break, circuit break and short
circuit. Test whether the insulation resistance of the heating
element is within the specified range.
Maintenance
Check whether all wiring is loose phenomenon Regularly; Check the
stroke switch regularly to prevent the furnace from being damaged
due to the improper action.
Furnace working conditions:
- The average monthly humidity in the area is no more than 90%;
- No explosive hazard, no corrosive gas or electric dust;
- No obvious vibration or turbulence; heavy surface slope is not
higher than 5℃;
- The control cabinet surface should keep clean;
- Check whether the instrument is working correctly regularly;
