Hitachi Econofresh - Removal of the Automatic Louver Motor

Tighten the nut by hand and apply the torque value: 12 Nm - 15 Nm.
N O T E
• Do not apply significant force to the motor, such as
rotational torque or bending load, while holding it with
your hand and tightening the nut.
• The direction of the eccentric part of the motor is fitted in
the same way as the expansion valve. Although the motor
is facing away from the piping connections on the valve
body, modification of this direction does not affect the
valve open/close function. Therefore, it is not necessary to
adjust the direction of the motor if the motor position
moves in the direction of rotation after replacement, as
shown in the figure.
• However, check that the motor direction for the electronic
expansion valve coil does not touch another pipe or the
side plate of the electrical box.
Once replaced, fit the electronic expansion valve in the reverse
manner as indicated for the removal process.
Position the butyl sheet, attaching it correctly to the valve.
N O T E
Check that the cables do not touch the fan duct after installation is complete.
