I found this service manual to be complete in every detail except for troubleshooting charts. It would be helpful if it had a set of troubleshooting charts; however it is a very good manual otherwise and for the price it is very well worth it.

11.3. Evacuation of Re-installation
WHEN REINSTALLING AN AIR CONDITIONER, BE SURE TO EVACUATE THE AIR INSIDE THE INDOOR UNIT AND PIPES in the following procedure. If air remain in the indoor unit and refrigeration pipes, it will affect the compressor, reduce to cooling capacity, and could lead to a malfunction.
Procedure: 1. Connect a charging hose with a push pin to the Low side of a charging set and the service port of the 3-way valve. � Be sure to connect the end of the charging hose with the push pin to the service port. 2. Connect the centre hose of the charging set to a vacuum pump. 3. Turn on the power switch of the vacuum pump and make sure that the needle in the gauge moves from 0 MPa (0 cmHg) to -0.1 MPa (-76 cmHg). Then evacuate the air for approximately ten minutes. 4. Close the Low side valve of the charging set and turn off the vacuum pump. Make sure that the needle in the gauge does not move after approximately five minutes. BE SURE TO TAKE THIS PROCEDURE IN ORDER TO AVOID GAS LEAKAGE. 5. Disconnect the charging hose from the vacuum pump. 6. Charge the pipes and indoor unit with gas refrigerant from 3-way valve service port, and then discharge the refrigerant until low side (gas side) gauge needle indicates 0.3 MPa (3 kg/cm2). 7. Tighten the service port cap at a torque of 18 N.m with a torque wrench. 8. Remove the valve caps of the 2-way valve and the 3way valve. Position both of the valves to �open� using a hexagonal wrench (4 mm). 9. Mount the valve caps onto the 2-way and 3-way valves. � BE SURE TO USE REFRIGERANT RECLAIMING EQUIPMENT WHILE REFRIGERANT. DISCHARGING THE
� Purge the air from charge set�s centre hose. � Be sure to check for gas leakage. Caution
If gauge needle does not move from 0 MPA (0 cmHg) to -0.1 MPa (-76 cmHg) in step (3) above, take the following measures: If the leaks stop when the piping connections are tightened further, continue working from step 3. If the leaks do not stop when the connections are retightened, repair the location of the leak.
