10-3-1. Replacing compressors

* For all types 90 and 140, follow the replacement procedure below.

(A) Replacing the inverter compressor (Compressor 1 on remote controller alarm display)

Removal

(1)Connect a manifold gauge to the high- and low-pressure outlet ports at the outdoor unit where the compressor will be replaced. Connect the manifold gauge to a nitrogen cylinder and perform nitrogen gas replacement in the outdoor unit tubings.

(2)Follow the instructions in “1. Removing Panels” and “2. Removing Electrical Component Box and Duct” and remove the corresponding parts from the outdoor unit where the compressor will be replaced.

(3) Remove the cap at the compressor terminal plate. Disconnect the power terminal. 2

(4)Remove the crankcase heater.

(5)Remove the 3 bolts, and remove the washers and rubber washers (quantities indicated in the figure below).

(6)Disconnect the tube-with-flare-nut using two adjustable wrenches. At this time, cover the tube in place with waste cloth while watching out for oil leaks. Then cap the disconnected tube and mount the flare nut on the compressor. Tighten the flare nut with a seal bonnet (1/4") in it.

NOTE	If oil remaining in the compressor reaches the equalized oil level, oil will come pouring out when the
	tube-with-flare-nut is removed.

(7) Prepare to disconnect the 2 brazed locations shown in the figure.

CAUTION

Protect the sensors and the surrounding plates, rubber, lead wires, clamps, and other items. Remove the discharge sensor shown in the figure 22.

(8)Disconnect the 2 brazed locations shown in the figure below.

(9)Pull the compressor toward you.

CAUTION

When pulling the compressor toward you, be careful not to cause any abnormal deformation of the tube-with-flare-nut.
