GENERAL DESCRIPTION
IMPORTANT: To the user of this manual – This
manual is a guide for installing, operating, and
maintaining this equipment. Refer to Table of
Contents for page location of detailed
information pertaining to questions that arise
during installation,operation, service and
maintenance, or troubleshooting this equipment.
GENERAL DESCRIPTION
This section gives the description, theory of operation, and design data for the Draft Arm with SF–1
Valve (dispensing valve), hereafter referred to as a
unit.
UNIT DESCRIPTION
The unit (see Figure 1) is compact and may be island–mounted or installed on a countertop. The unit
may be used to dispense tea or may be connected
into a post–mix system to dispense a carbonated or
non–carbonated (still) drink. Adjustable water and
syrup flow regulators, located in the dispensing
valve, are easily accessible to control water flow rate
and to adjust Water–to–Concentrate (tea) or syrup
(post–mix) ‘‘Ratio’’ of dispensed product. An optional
Draft Arm Base Kit (P/N 319314–039) with drip tray
and drain hose is available.
Installation of unit on countertop, connection of unit
to tea or post–mix system, and adjustment of dispensing valve water and syrup flow regulators for
water flow rate and water–to–concentrate (tea) or
syrup (post–mix) ‘‘Ratio’’ of dispensed product is all
that is required for operation.

THEORY OF OPERATION (see Figure 2)
UNIT USED AS A TEA DISPENSER (see Figure
2)
A nitrogen (N) gas cylinder delivers gas through an
adjustable nitrogen gas regulator to the concentrate
tank. Gas pressure exerted upon contents inside
concentrate tank pushes concentrate from tank to
dispensing valve. At the same time, plain water is
pushed by city water line pressure to the dispensing
valve. Concentrate and plain water pass through adjustable water and syrup (concentrate) regulators in
the dispensing valve and meet simultaneously at the
valve nozzle resulting in finished product being dispensed.
UNIT CONNECTED TO A POST–MIX SYSTEM
The unit may be connected into a post–mix system
to dispense a carbonated or a non–carbonated (still
drink). The unit is shipped from the factory with
Baffle Tube Extension (P/N 300097–000) and Baffle
(P/N 318754–011) installed on the dispensing valve
and is intended to dispense tea. If unit will be connected into post–mix system, tube extension and
baffle should be removed and BAFFLE (item 12)
should be installed on valve for better mixing of dispensed product.
