(3) How to attach and detach the coil of linear expansion valve
<Composition>
Linear expansion valve is separable into the main body and the coil as shown in the diagram below.
<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 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.
