N O T E
Do not hold onto the motor when loosening the nut with a
wrench. The base of the transmission part could become
loose and break.
Loosen the nut several turns to release the transmission part from
the bolt.
Prepare the new transmission part (spare part) with the position of
the transmission wheel (transmission bolt) already adjusted.
N O T E
• Pay attention to removal while replacing and prevent dust
and foreign particles, etc. from entering it (the exposed
part during removal is the mechanical part of the valve).
• Do not damage the valve joint with tools.
Fit the transmission part to the body of the valve, hold onto both
and make sure their axes coincide before tting the nut to the
valve body bolt.
Tighten the nut by hand and apply the torque value: 12 Nm - 15 Nm.
N O T E
• Donotapplysignicant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ttedinthesamewayastheexpansionvalve.Althoughthe
motorisfacingawayfromthepipingconnectionsonthevalvebody,modication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gure.
• 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, t 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.
