8.Removing the 4-way valve

(1)Remove the service panel. (See figure 1.)

(2)Remove the top panel. (See figure 1.)

(3)Remove 3 valve bed fixing screws (4 ✕ 10), 4 ball valve

and stop valve fixing screws (5 ✕ 16), then remove the valve bed.

(4)Remove 4 right side panel fixing screw (5 ✕ 10) in the rear of the unit and then remove the right side panel.

(5)Remove the 4-way valve coil. (See photo 7.)

(6)Recover refrigerant.

(7)Remove the welded part of 4-way valve.

Note 1: Recover 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 4-way valve, cover it with a
wet cloth to prevent it from heating (250˚F or more),
then braze the pipes so that the inside of pipes		4-way way	4-way valve
