NOTE
3.3 CONDENSER CLEANING (AIR-COOLED
MACHINES)
The condenser requires periodic cleaning. To clean, refer
to the following procedures.
A. Disconnect power to the machine.
B. Remove the right side panel.
C. To remove the condenser fi lter, grasp the top and
pull off. Visually inspect the fi lter for dirt. If it is
dirty, shake or brush excess dirt off of it and wash
it in warm, soapy water. Once the fi lter is clean,
rinse it thoroughly in warm, clear water and shake
dry, taking care not to damage it in any way.
If the condenser is not kept clean, refrigeration ef-
fi ciency will be lost.

3.4 COIN CHANGER MAINTENANCE

The coin changer attempts to maintain a certain quantity
of coins in the coin tubes. This quantity is called the "fl oat"
(also known as PAR setting). The ideal fl oat is to have
just enough coins needed to provide change to every
customer between maintenance visits.
FLOAT OPERATION
During maintenance, use the fl oat operation to dispense or
insert coins to bring the coin level to the fl oat setting. The
factory default fl oat setting is full tubes (the fl oat operation
will request coins to be inserted until each coin tube is full)
Refer to the MEI Cashfl ow operation guide for in-
formation on how to change the fl oat value.
A. Press the yellow button on the coin manager to
access the menu.
B. Press the A button to select FLOAT
C. After two seconds, the changer dispenses any
excess coins.
D. If a coin tube is low, the display shows the quantity
needed to achieve the fl oat value. Add coins or
press Skip.
E. Press the Finish button.
