DISASSEMBLING/ASSEMBLING PROCEDURE CV-160
DISASSEMBLING/ASSEMBLING PROCEDURE
1. General Precautions on Disassembling/Assembling
• Replace the parts and wires to the original positions.
• For electrical safety and standard, be sure to reassemble the following parts to the original
states.
① Insulation tube and mylar sheet
② Cables clamped and separated from the heating parts or high-voltage parts
③ Cover screws with a toothed lock washer to suppress a radiation noise
• Use the specified parts.
• The parts used in this unit are designed protective against vibration, heat and high voltage. Be
sure to select the parts with the same characteristics from the parts list when replacing the
parts.
• Be careful when disconnecting the cable housing.
• Don’t pull the cable. Be sure to use the special tool.
• Be careful not to be injured.
Some metallic parts have sharp corner or edge. Be careful when handling such parts.
• Be sure to observe the specified torque and dimensions.
Observe the torque and dimensions when they are specified.
As for the H-band which secures each tube, first tighten it by the specified torque and then pull
the tube to check whether the tube becomes loose or it comes off.
• Clean the parts to be used.
When re-using the same parts, eliminate the sealing material and tape and clean. For the
O-ring and packing, clean the surface of the parts on which the O-ring or packing is mounted.
Otherwise, it may cause water leakage.
• Don't forget to tighten the screws and nuts.
Failure in tightening the screws and nuts may cause water leakage.
