Readable text and good copy. Very much needed if you wish to do some repairs on this fine old unit.

Fint forløb med levering af manualen. Kvaliteten af skanningen betegnes som middel

I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
;
I will highly recommend this seller. They are honest, accurate, fast and responsible.

This manual was very good & was very helpful with repairs.
Always great & fast service from Owner's manual.
