OPERATING PROCEDURE
8. Removing the four-way valve
(1) Remove the service panel. (See photo 2.)
(2) Remove the top panel. (See photo 1.)
(3) Remove the front panel. (See photo 1.)
(4) Remove the back panel. (See photo 1.)
(5) Remove the electrical parts box. (See photo 5.)
(6) Remove the solenoid valve coil <Four-way valve>
(See photo 8.)
(7) Collect the refrigerant.
(8) Remove the welded part of four-way valve.
Note 1: Collect refrigerant without spreading it in the air.
Note 2: The welded part can be removed easily by remov-
ing the right side panel.
Note 3: When installing the four-way valve, cover it with a
we cloth to prevent it from heating (120°C or more),
then braze the pipes so that the inside of pipes
are not oxidized.
9. Removing linear expansion valve
(1) Remove the service panel. (See photo 2.)
(2) Remove the top panel. (See photo 1.)
(3) Remove the front panel. (See photo 1.)
(4) Remove the back panel. (See photo 1.)
(5) Remove the electrical parts box. (See photo 5.)
(6) Remove the linear expansion valve coil . (See photo 8.)
(7) Collect the refrigerant.
(8) Remove the welded part of linear expansion valve.
Note 1: Collect refrigerant without spreading it in the air.
Note 2: The welded part can be removed easily by remov-
ing the back panel.
Note 3: When installing the linear expansion valve, cover
it with a wet cloth to prevent it from heating
(120°C or more), then braze the pipes so that the
inside of pipes are not oxidized.
10. Removing the high pressure switch (63H)
(1) Remove the service panel. (See photo 2.)
