N O T E
Remove the right-hand cover instead of the front panel on
RPK-(2.5-4.0)FSN2M models.
Remove the electrical box as indicated in section Remove the
electrical box panel, see on page 329.
Remove the sheet from the piping surface, the valve coil and the
valve body.
N O T E
The butyl sheet is attached around the heat exchanger piping,
the electronic expansion valve and the inlet and outlet piping
of the electronic expansion valve.
Prepare two wrenches. Secure the body of the valve with one wrench and loosen the nut with the other, turning it anti-
clockwise until the transmission part is released and can be removed.
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.
Prepare the new transmission part with the position of the transmission wheel 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 fitting the nut to
the valve body bolt.
