Routine Maintenance
WARNING
Switch off the power to the host
machine before cleaning the unit
Clean the coin pathway (shown shaded in the
figure) regularly with a soft cloth moistened with
water. Take care that all the surfaces are dry before
you close the lid of the unit, particularly if you have
had to clean the unit after the entry of dirt or fluid.

Opening

Lid

Clean the
shaded areas

Take care that no drops of water enter the unit

during cleaning.
Never use solvents or abrasive creams to clean the
unit. These will damage the surfaces. Ensure that
the lid is fully closed after cleaning.
NOTE: If you switch the machine on when
the lid of the acceptor unit is not fully closed,
coins will be rejected, even if you then close
the lid.
If this happens, switch off the power to the
machine for at least 15 seconds, then close the
lid again. Make sure the lid snaps shut.
Switch the power on. Check that coins are
accepted.

Using the Keypad
Dispense Coins / Empty Tubes
A , B , C or D
Press a button once to dispense a coin from a
corresponding tube. If you press and hold for more
than three seconds, coins are dispensed
automatically until only a sufficient minimum (the
safe count) are left to operate the dispense
mechanism. To empty a tube or a cassette, you
may have to take out the last coins by hand.

Float-Up Tube Counts Automatically

+ A
Press the buttons, then feed tube coins through the
acceptor to refill the tubes to their pre-set float
level. When float levels are reached, further coins
are rejected. If automatic float is left by pressing B,
tube counts re-set to pre-programmed float levels.
Re-set the Tube Counts
+ A + B ★
Press the buttons to force tube counts to re-set to
pre-set float levels. If there are not enough tube
coins to meet the pre-set levels, coin counts remain
incorrect until recalibration takes place. ★ If an
audit FEM is fitted, reset via Mode+A+B is not
available.
Automatic Float Down to Pre-set Levels
+ A + C
If the unit is programmed for this function,
press the buttons to dispense coins until tube
counts reach their pre-set float levels. If the
numbers of coins already in the tubes are equal to
or below the float levels, no coins are dispensed.
Set the Vend Prices ◆
+ C
Press the buttons. Insert coins equal to the lowest
price. Make a selection. A 45-second time-out
starts after each coin. More selections at the same
price can be made without inserting extra coins.
Add coins for the next highest price, and make a
selection. Continue until all prices are set. Press C
to cancel credit and to exit price teach.

Connect the looms and secure them

in their correct positions
1. Check that the looms cannot be trapped by the
unit or by the door of the machine.
2. Check that the unit’s lid opens fully when the
reject button is pressed, and that the lever has
2mm - 3mm of clearance from the reject
mechanism of the machine. Adjust the clearance if
necessary.
3. Ensure that the unit’s coin entry cup is
aligned with the machine’s coin entry chute,
and that the coin exit chutes are lined up.
4. With the power off, insert ten of the largest and
