Inventory (Stock): a rather extensive list of service manuals, which are hard to find, especially 15+ yrs old.
Pricing: very reasonable.
Delivery/Response: Very Prompt delivery of product: Placed order and received download access within 1.5hrs.
Service Manual: a rather complete OEM service manual (15.5MB pdf file size). Scan quality was very good, accept for a few circuit board diagrams that were dark; Zooming, however, clarified the image. Has the required information for servicing the LD Player.

� 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.
