7. Maintenance
The EMP 500 v7 /CLB is an extraordinarily robust coin selector and
operates relatively maintenance free. However, it should be cleaned at
regular intervals especially if it is operating in an environment with high
levels of dust, smoke or nicotine. The cleaning intervals are of course
dependent on the level of air borne contaminants.
Modest use with minimum contaminant levels indicate the need to clean
the top of the coin path once a year. Open the coin path door and wipe
the exposed surfaces with an alcohol moistened cloth. Also lukewarm
water with a little washing-up liquid may be used. It is important that no
dirt is pushed inside the openings of the optical sensors. The light sensors
may be cleaned with a soft brush or air duster spray.
Make sure that the coin selector is without power during the
cleaning.
Use a damp not wet - cloth. Under no circumstance’s liquid
should run into the coin selector.
Avoid solvent or abrasives which may affect the plastic
material.
Never use an oily rag! Never lubricate the solenoid, hinge
joints etc.!
