This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.
;
A complete manual with all the needed details of calibrations and service instructions about the radio receiver.
A big deal.
Many thanks !

� Installation
(1) Connect the piping between the indoor and outdoor unit firmly. � Incorrect connection may cause the leakage and incomplete vacuuming. (2) Attach the charging hose (manifold gage) to the service port. � Charging hose is necessary to check the pressure and to inject R22 for leakage test. � The valve of charging hose must be closed before being connected. (3) Inject the 100~300g R22 through the charging hose opening the valve. (4) Check the joint part using a gas detector or soapy water for leakage. � On checking, the service valve of main service port must be closed, this test is only for checking whether pipe connection is ok or not. (5) If there is no leakage, discharge R22 in piping completely into tank for retrieving. � Complete discharge is needed for vacuuming. � If leakage is found, please fasten the joint more tightly. (6) After closing the valve of charging hose, disconnect the tank and connect the vacuum pump to charging hose and open the valve again for vacuuming. (7) Turn on the vacuum pump until the pressure drops below 0kg/cm2. (8) After vacuuming, disconnect the vacuum pump and open the spindle of service port (liquid-side) slightly for 30 sec and then open the spindle of (gas side) with hexagonal wrench. (9) Open the liquid side completely first and then the gas side fully in order.
