WARNING: TURN OFF all power source switches
NOTE:
Do not apply the strong forces such as the rotating torque
and the bending load to the motor by holding the motor by
hand when tightening the lock nut.
Although the direction of the eccentric part of the motor is
assembled with the eccentric part of the motor directed
toward the counterdirection of the fittings for piping at the
valve body, the alteration of this direction do not affect the
open/close function of the valve.
Therefore, the adjustment of the direction of the motor part
is not required if the position of the motor is moved toward
the rotating direction after replacement as shown in the
Figire 2.
However, pay attention to the direction of the motor for the
coil of the electronic expansion valve not to touch other
pipings and the side plate of the electrical box.
5. Attach the removed butyl sheet to the electronic expansion
valve again.
6. After completion of the replacement, attach the electronic
expansion valve in the reverse procedures for removing.
