<How to detach the coil>

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and detach the coil by pulling it upward.

Be sure to detach the coil holding main body firmly. Otherwise pipes can bend due to pressure.

<How to attach the coil>

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and attach the coil by inserting it downward into the main body. Then securely attach the coil stop- per to pipe B. (At this time, be careful that stress is not added to lead wire and main body is not wounded by lead wire.) If the stopper is not firmly attached to pipe B, coil may be detached from the main body and that can cause defective operation of lin- ear expansion valve.

To prevent piping stress, be sure to attach the coil holding the main body of linear expansion valve firmly. Otherwise pipe may break.

Be sure to attach the stopper to pipe B.
