TEA BREWER FEATURE DESCRIPTIONS
The AKPA brewer incorporates the latest features in brewer control technology. Although providing for enhanced functionality
brewer controls remain intuitive and setup of key operating parameters couldn't be easier. Multiple brew volumes, visa-brew
delay, tank temperature set point, brew mode, filter parameters and more are all set from the front control panel using a digital
display for precise control. The Tim Horton brewers incorporate an additional program sequence, "Quality Check", which
allows display of the programmed brew volume(s) in ounces, actual tank temperature and number of brews. The quality
information is displayed using a quality check button. The following pages will explain the control features and then step
through the process required to program your unit.
Brew Volume – The Digi Brew II series control has two independently programmable brew volumes denoted Tea
1/2 and Tea 1. Brew time is set by desired brew volume in ounces. Either of these brew times may be turned off or set for any
volume from 30 ounces to 255 ounces for the ultimate in flexibility. Selected brew volume is converted to brew time internally
for calculations and to add to countdown time. PDS valve must be calibrated to deliver 1/4 gallon per minute in order to
ensure programmed brew volume is delivered.
Quality Check Mode – The quality check mode is used to display the programmed brew volume(s) in ounces, actual tank
temperature and the total number of brews for each side. To activate the display depress the quality check button. When the
button is depressed the display will show the programmed volume in ounces that brew one (TEA 1/2) is set for. Subsequent
presses of the QUALITY button will display brew volume for brew 2 (TEA 1), the actual tank temperature and total number of
brews for brew 1 and brew 2. The selected item will display until beginning a brew cycle or pressing cancel.
Visa-Brew Time – Provides for additional time to add to the programmed brew time. This additional time allows display to
continue countdown after the water delivery portion of brew cycle to allow for the coffee to finish draining from the brew basket.
The digital countdown, and the delay in the audible coffee ready signal, aid in preventing premature removal of either the brew
basket or the dispenser.
Water Temperature Set Point – Allows for digitally setting the temperature of the water in the brewers tank system to any
value between 170 and 205 Deg F. Caution: Brewer temperature is set at 203 deg and Hot Water Dispenser is set at 205 deg.
In higher altitude locations, over 3500 feet above sea level, the temperature will need to be adjusted down to prevent boiling.
Auto Arm – When enabled this feature ensures that the brewer is up to temperature prior to brewing to ensure proper
extraction is obtained. If the water temperature in the tank is below the water temperature set point when the brew cycle is
initiated the water delivery portion of the brew cycle is delayed. The heating light will begin to flash indicating that the unit is in
the brew mode but is not up to temperature. At the same time the tank heater will begin heating and when the tank reaches
the preset temperature the brew cycle will resume. Auto arm may be overridden by pressing and holding the appropriate brew
button for several seconds until the brew cycle starts.
Pre-infusion mode – This mode delivers a small amount of hot water over the coffee grounds and then pauses to allow wetting
of the brewed product and to allow the product to absorb the water before continuing. After this pause the brew cycle resumes
normally. Pre-infusion can yield better extraction rates than normal brewing modes. The pause time is added to the brew and
visa-brew time. The pre-infusion times are preset at the factory. Pre-infusion for Brew 1 and 2 may be turned on and off
independently.
Pulse Brew Mode – This mode cycles the fill valve on and off during the brew cycle. This slows the entry of cold water into the
tank and minimizes the mixing action caused by introducing a large volume of cold water into the tank at one time resulting in
an increase in brew temperature. The additional turbulence and mixing created in the brew basket along with the increased
temperature can result in higher extraction rates for the coffee or tea. The time set for pulse brewing should exceed the time
required for brewing. The time difference between the pulse brew time and the brew time is the amount of time available as
off time. The difference is divided equally and distributed throughout the brew cycle to provide a pulse after every 30 seconds
of brewing. Pulse brew mode for Brew 1 and 2 may be turned on and off independently.
Audible Alert Mode – Provides an audible signal when tea has finished brewing notifying everybody that fresh tea is available.
May be turned off, set for 1-9 beeps or set to on for continuous beeping until cancel button is depressed. The empty basket
light will also flash to prompt operator to dump grounds from brew basket.
Brew Ready – Monitors the temperature of the water in the tank and lights when the programmed temperature has been
reached. If a brew cycle is started when the icon is not lit brew temperature may not be optimal if the autoarm feature,
described above, has been turned off.
