WATER FILTERS
It is recommended that proper water filters treat the
water supply for the beverages. There are two basic
filters commonly in use.
1. Pre-filter, or sand filter. This filter removes any
foreign matter from the water down to 25 microns
in size.
2. Carbon or activated charcoal filter is also used.
This filter will reduce chlorine and other
chemicals, off-taste and odor. Some of the higher
quality filters may reduce organic compounds
(bacteria) in the water.
Do not use a filter containing any type of phosphate on
the beverage system. Phosphate as used for scale
reduction will cause the beverage to lose its
carbonation and become “flat” quickly.
WATER PRESSURES
Dynamic (flowing) water pressures to most
carbonators should be a minimum of 40 PSI
(1.38 bar). Water pressure to dispensers for
noncarbonated beverages should be a minimum of
50 pounds (22.7 kg). These pressures are minimum
operating pressures, not static pressure.
SYRUP BASICS
Your concentrated syrup containers should be stored
in a cool dry location that is easily accessible. Any
extremes in temperature can wreak havoc with the
quality of the product. For best results, the syrup
should be maintained in an environment between 40°
and 90°F (4.4° and 32.2°C).
