GENERAL DESCRIPTION
This section provides a description, theory of
operation, and design data for the Tea Urn Post-Mix
Beverage Dispenser, hereinafter referred to as a
Unit.
UNIT DESCRIPTION
The Unit (see Figure 1) is compact and intended for
countertop installation. The Unit dispenses
liquid-base concentrate combined with water to
create a finished drink. The Unit is operated by
pressing against a lever arm which extends below
the dispensing valve Cover.
Components are mounted on a stainless steel
enclosure which rests on the countertop. External
connections required are a plain water source and a
source of concentrate.

THEORY OF OPERATION
(see Figure 2)
Note: The gas-operated concentrate pump in the
system, which provides concentrate to the
Dispenser, may be driven by carbon dioxide
(CO
) gas or by compressed air or an electrically
2
operated pump may be used in place of the
gas-operated pump.
The concentrate is stored in a collapsible bag within
a sturdy box which is called a bag–in–box. When the
dispensing valve is opened, a pump operated by gas
pressure delivers concentrate from the bag-in-box to
the dispensing valve. At the same time, plain water
also enters the dispensing valve. Concentrate and
plain water meet simultaneously at the dispensing
valve resulting in a finished drink being dispensed.
Dispensing continues from the valve as long as the
dispense lever is held down.
The dispensing valve components are accessible by
removing hex nut securing cover to the valve, then
remove cover. The dispensing valve can be removed
from the Unit entirely by releasing two latches.
Concentrate and plain water connections are made
to flared fittings on back side of the Unit.
Components are mounted on a Stainless Steel
Enclosure which may be fastened to the countertop.
The Unit is available with or without a removable Drip
Tray and Cup Rest.
