Removing Bypass Valve Coil (Sv); Removing The Reactor (Dcl) And Capacitor (Cb); Removing The High Pressure Sensor (63Hs) - Mitsubishi Electric PUHZ-HRP71VHA Service Manual

OPERATING PROCEDURE
11. Removing bypass valve coil (SV) and bypass valve
(Only for PUHZ-HRP·V/YHA, PUHZ-HRP·V/YHA2)
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Remove the side panel (R) fixing screws (3 for rear, 5 × 12)
in the rear of the unit and remove the side panel (R).
(4) Remove the bypass valve solenoid coil fixing screw (M5 × 6).
(5) Remove the bypass valve coil by sliding the coil upward.
(6) Disconnect the connector SV2 (blue) on the controller cir-
cuit board in the electrical parts box.
(7) Recover refrigerant.
(8) Remove the welded part of bypass valve.
Note 1: Recover refrigerant without spreading it in the
air.
Note 2: The welded part can be removed easily by
removing the right side panel.

12. Removing the reactor (DCL) and capacitor (CB)

(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Remove the electrical parts box. (See Photo 3)
[Removing the reactor]
(4) Remove the reactor fixing screws (4 for rear, 4 × 10) and
remove the reactor.
[Removing the capacitor]
(4) Remove the capacitor band fixing screws (2 for rear, 4 × 10)
and remove the capacitor.
* The reactor and capacitor are attached to the rear of the
electrical parts box.

13. Removing the high pressure sensor (63HS)

(Only for HRP71/100VHA2(R1))
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Pull out the lead wire of high pressure sensor.
(4) Recover refrigerant.
(5) Remove the welded part of high pressure sensor.
Note 1: Recover refrigerant without spreading it in the
air.
Note 2: The welded part can be removed easily by
removing the side panel (R).
Note 3: When installing the high pressure sensor, make
sure to cover it with a wet cloth to prevent it from
heating (100°C or more), then braze the pipes so
that the inside of pipes are not oxidized.
