Exchange a comp. leads together as replacing a
compressors.
* The right fig. 1 shows caution when the comp. leads
are installed.
• Incorporate the terminal block into the compressor.
• Bend each terminal at 90°while holding the terminal

(3) Tighten them with the specified torque using a
torque wrench driver. (2.5N•m)
* Do not screw the screws slantingly.
Otherwise, the comp.leads may burn.
• Insert the comp.leads into the sealing material, and
attach the terminal cover so that they do not pinch
with the terminal cover, and then draw out the
comp.leads straightly.
• Do not apply excessive stress to the comp.leads.
• Do not put the protective tubes in the terminal cover.
• Note that the leads do not touch the comp. shell.
3) Wrap the soundproof material*1 around the
