Proper installation requires that the dumbwaiters operate only
when all access doors are closed. PDC has learned that some
installers are not properly securing the safety switches, one
magnetic piece to each door and the other magnetic piece to
each door frame. The proper installation will allow these
magnetic switches to be in contact only when the doors are
fully closed. If one side of the safety switch were
to separate from its intended location and remain in contact
with the other side of the safety switch, the system will operate
as though the door were closed, even if the door is open.
Please check to see that your dumbwaiter does not operate
when each door is open. Check all doors, one at a time, to
ensure safe operation.
If your dumbwaiter door safety switches are not there, or are
not working properly please call us at the number below
and we will send you a new set FREE OF CHARGE.
Please call us with any questions at (800) 409-5438 or
(530) 333-1953 between 7am and 3pm, Pacific Standard
Time, Monday through Friday.
