motor in order to conduct capacity control
operation.
1. Replacing the coil
● Coil removing procedure
(1) Disconnect the SMV lead wire connector
q from the inside of control box.
(2) Cut the binding band e at the upper rubber cover

the coil r.
Note) Engage the dimple i of coil bracket u
with the dimple (protrusion) o of coil r,
and adjust the angle as shown in the
Fig. D.
Since the angle adjustment is important
for control of suction modulating value,
carry out the adjusting accurately.
(2) Fix the coil r and coil bracket u with the tie
wrap t so that the coil r and the position of
the dimple of coil bracket u should not be
displaced.
Note) Ensure that the tie wrap is not tilted.
