DISASSEMBLY
There are three active parts to the coin validator,
the control unit, power supply and face plate. The
control unit plugs into a display circuit board
forming part of the centre plate and power supply
on the opposite side. This assembly is held
together by two security screws, one from each
side of the unit. They form one assembly, covered
by a single serial number.
PROCEDURE
1. Using a neat fitting bladed screwdriver, remove
the right-hand plastic holding screw located
under the ledge on the right side.
2. Remove the identical left-side screw located
at the top of the left moulding.
3. The two side mouldings are now free to slide
off the middle fascia moulding. They are
removed by pulling directly backwards from
the fascia.
CLEANING OF COIN TRACK
After considerable use there may be a build up of
dirt on the coin track that impedes the flow of coins
and the validator will need opening for cleaning.
Also foreign objects placed in the validator which
do not pass through the system will need to be
cleaned out. To disassemble remove the two
security screws, one each side of the validator.
These are clearly marked with the control board
screw being at the top and the other screw being
at the bottom on the other side. The control board
mechanism can then be withdrawn by pulling
backwards. When cleaning the coin track it is
important to ensure that the two
holes are not filled with dirt. Clean with industrial
alcohol or methylated spirits. Take care not to
leave a residue in the optical sensor holes but do
not use a pin or similar to clean into the holes as
the optical lens may be scratched.
NOTE: Care should be taken in reassembling the
validator to ensure that the pins on the front
display board make proper physical connection
into a mating socket on the control board.
