Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++
 ;
Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

It is OK, this manual help me to repair my dynacord

1 Evacuation of Installation
When installing an air conditioner, be sure to evacuate the air inside the indoor unit and pipes in the following procedure. Required tools: hexagonal wrench, adjustable wrench, torque wrenches, wrench to hold the joints, gas leak detector, and charging set.
(Indoor unit) (Liquid side) 3-way valve Close
The air in the indoor unit and in the piping must be purged. If air remains in the refrigeration pipings, it will affect the compressor, reduce the cooling capacity, and could lead to a malfunction.
(Outdoor unit)
(Gas side)
3-way valve OPEN Close Vacuum pump
Lo Hi
OPEN
Service port cap Be sure, using a torque wrench to tighten the service port cap (after using the service port), so that it prevents the gas leakage from the refrigeration cycle.
Procedure:
(1) Connect a charging hose with a push pin to the Low and High sides of a charging set and the service ports of a 3-way valves. q 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 cmHg (0 MPa) to �76 cmHg (�0.1 MPa). Then evacuate the air for approximately 10 minutes. (4) Close the valve of both the Low and High sides of the charging set and turn off the vacuum pump. Make sure that the needle in the gauge does not move after approximately 5 minutes. BE SURE TO TAKE THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT GAS LEAKAGE. (5) Disconnect the charging hose from the vacuum pump and from the service ports of the 3-way valves.
� 26 �
(6) Tighten the service port caps of both the 3-way valves at a torque of 18 N�m with a torque wrench. (7) Remove the valve caps of both the 3-way valves. Position both of the valves to �open� using a hexagonal wrench (4 mm). (8) Mount valve caps onto both of the 3-way valves. q Be sure to check for gas leakage.
Caution
If gauge needle does not move from 0 cmHg (0 MPa) to �76 cmHg (�0.1 MPa) 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.
