1 Remove the switch box cover, top panel,
back panel, left side panel, and right side
panel in accordance with “Procedure for
Removing Outside Panel Block (P.133)”.
① Remove the dew proofing
material.
② Recover refrigerant from the
service port.
③ Detach the EEV (Y1E) coil by
pulling out it upward. When
replacing the coil, disconnect the
connector (S90) on the control
board, and pull out the coil lead
wire from the wiring port (see
page 134) (*2). Remove the band
banding the coil lead wires in the
oil cooling unit.
④ Remove the EEV outlet thermistor
(Th-8) from the thermistor holder.
⑤ Disconnect the two brazing
sections to remove the EE valve
(for main circuit) (Y1E) main unit.
① Recover refrigerant from the
service port.
② Pull out the MOV (Y2E) coil.
When replacing the coil,
disconnect the connector
(CN7) on the inverter board,
and pull out the coil lead wire
from the wiring port (see
page 111) (*2). Remove the
band banding the coil lead
wires in the oil cooling unit.
③ Disconnect the two brazing
sections to remove the MO
valve for hot gas (Y2E) main
unit.

After the motor operated
valve (for main circuit
and hot gas) main unit is
replaced, the fully closed
pulse must be set up for
each valve. Be sure to
perform the pulse detection
operation with EEV (MOV)
fully closed. (refer to
page 150)

Once the sealing material
of the wiring port is
removed, its dust-preventive
performance is degraded.

Change the removed sealing
material with a new one
before taking in lead wire
again.
