SERVICE & INSTALLATION MANUAL - Symbol
8.4 Brew Group Assembly
Preventive maintenance: yearly or every 25,000 coffee cycles
The brew group is the heart of the equipment and is responsible for the taste of every cup. It needs
to be serviced regularly to maintain the quality of the beverages served.
1. Evoca North America offers a Brew Group Exchange Program. This
program ensures a constant running of the machine by receiving
a replacement brew group to use while maintenance is performed
on the actual brew group of the unit. Evoca North America will
completely clean and replace all parts requiring maintenance,
including the screen and seal, the cylinder and the piston seal.
The cleaned brew group will be returned with a one (1)year warranty on defective parts.
Contact salesorder.na@evocagroup.com or 800-561-6162, ext.311, to order parts or for
additional information.

dispensed coffee.
