(3) How to attach and detach the coil of linear expansion valve

Linear expansion valve is separable into the main body and the coil as shown in the diagram below.

Be sure to attach

the stopper.

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 main body. (At this time, be careful that stress is not added

to lead wire and main body is not wound by lead wire.) If the

stopper is not firmly attached to main body, 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.

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.
