6.4. Low voltage transformer
and/or power relays (RY1,
RY2, RY4, RY5, RY6, RY7)
NOTE:
Be sure to ground any static electric charge built up on
your body before handling the D.P.C.
1. Disconnect all connectors from D.P.C. board.
2. Remove 6 screws holding D.P.C. board on escutcheon
base.
3. Replace D.P.C. board.
(A) Using solder wick or a desoldering tool and 30W
soldering iron carefully remove all solder from the terminal
pins of the low voltage transformer and/or power relays.
NOTE:
Do not use a soldering iron or desoldering tool of
