4-8. Key points in disassembly
4-8-1 Points of attention in maintance
1) General attention
● Be sure to pull off the power plug in disassembly or maintenance
● Use stipulated crimp terminals in connecting the wires between the conducting wires as far as possible,
and fix with suitable tools; and insulate with insulation tape competely.
● In inserting the conducting wires, be sure to plug the pins to the root and make it hard to be pulled out.
● If welding is needed, be careful not to touch the plastic or other insulation parts with the iron.
● When connecting the wires, be sure not to make the wire touch the mobile parts like the belt, radiating
pulley and jib etc., and the sharp protruding parts and the parts with high temperature (motor). Connect
and fix the wires as per their original mode.
● If there's metal object at the wire fixing point, be sure to insulate with insulation materials.
Retain the diamantled screws for future usage in installation.
2)Points of attention in usage of electric components
In case that the power is on, the earthing circuit of the computer sequencer can have 120V voltage to
earth.Take care not to get electric shock.
● Store the computer sequencer and driver under 4℃-30℃ . Avoid direct sunlight.
In trouble-shooting, it may require hot-line work. Please be extremely carefull
The part of control panel seat
1)Method of opening the control panel
A Open the back cover Loosen the three locking belt fixed on the cabinet(used in inner wiring),to loosen
the inner wiring.
B Loosen the four screws used to install the control panel seat(rear and side).
Lift the rear upwards. Loosen the control panel seat from the inlay cabinet .
Attention:
●Do not Lift the control panel seat by force ,otherwise the safty switch control rod may get transformed, and
the jointer part of the conncting pipe of the water lever sensor may be loosened, therefore influence the
normal operation of the microswitch and water level sensor
● After opening the control panel seat, hole it with one hand or lean it on supporter like the wall. Do not
put it down.
