to replace the coin samples with a different type of coin, the selectivity of the unit must be
readjusted. Before this can be done, a standard acceptance test should be performed. The
test is performed by dropping several valid coins into the Slug-Buster II, including common
slugs, and verifying that the proper coins are credited and that the slugs are rejected. If the
acceptor does not recognize all of the coins, or does not reject the invalid coins, the following
procedure should be implemented.
Note:
The coin acceptor must be powered to make a valid adjustment to the sensitivity. You
must also avoid testing the Slug-buster II with the door open in direct sunlight. If the
Slug-Buster II main mechanism is exposed to direct sunlight, it may fail to credit the
coin.
1. Locate the coin holder housing a quarter in the sample holder. Check the coin to
ensure it is properly centered in the sensing coils and it is seated securely.
2. Loosen the cover nut to the electronics box on the opposite side of the coin
acceptor. Spin the 1” x 2-1/2” cover, exposing the selectivity trim pot.
3. Locate the trim pot in the round hole that has been exposed by spinning the
cover. The trim pot is marked “QUARTERS” and controls the quarter selectivity.
4. Begin dropping the quarters or lower value coins into the unit, slowly turning the
trim pot marked “QUARTERS” counter-clockwise (ACCEPT), until the Slug-
Buster II begins to accept the coins.
5. Turn the trim pot an additional 2–5 degrees counter-clockwise (ACCEPT), and
stop. This completes the smaller value coin adjustment.
4.4.3 Removing the Coin Acceptor
If you find it necessary to remove the Slug-Buster from the Wash Select II door, a small head
Phillip’s screwdriver will be needed.
Follow the steps below to remove the assembly from the door.
1. Locate the rejected coin cup, which is mounted on the front of the Wash Select II
door underneath the coin acceptor slot.
2. Using a small Phillip’s head screwdriver, remove the screws from the inside of the
Wash Select II door that are securing the rejected coin cup. The cup should slide
off from the front of the door after removing the screws.
Note:
When replacing the coin acceptor, make sure that the exit chute is aligned with the coin
diverter/guide assembly properly. Failure to align the two may result in coin jams or
loose coins falling to the bottom of the Wash Select II case.
3. Use a ¼” nut driver to remove the four nuts that are located at the corners of the
faceplate. (The screws can be found inside of the Wash Select II door. The lower
screws are located next to the rejected coin cup and the upper screws are located
just above the coin acceptance slot.)
4. Grasp the unit in one hand and loosen the nuts with the other hand. Once the
nuts have been removed, the complete assembly can be removed by pulling it
out and away from the Wash Select II door.
