BREWER SETUP PLUMBER'S INSTALLATION INSTRUCTIONS

CAUTION:

1) Flush water line before installing brewer. Brewer should be connected to COLD WATER LINE for best operation.

2) Water pressure should be at least 20 lbs. For less than a 25 ft run, use 1/4" copper tubing and connect to 1/2" or larger water line. For longer runs, use 3/8" copper tubing & connect to 1/2" or larger water line and provide an adapter fitting for connection to the brewer.

3) If installed with saddle valve, the valve should have a minimum of 1/8" port hole for up to 25 ft run, and 5/16" port hole for over 25 ft runs.

4) Connect incoming water line to the flow control device on the back of the brewer. A 1/4” flare fitting is provided. Manufacturer recommends connecting to copper tubing.

ELECTRICAL HOOKUP WARNING:

be void if machine is connected to any voltage other than that specified on the name plate. The brewer has a power cord attached and is configured with a twist type plug, NEMA type L14-30. Brewer should be

connected to the appropriate receptacle type. A wiring diagram at the rear of this manual illustrates the complete brewer wiring. Note that the tank heater system is the only portion of the brewer running on 240V. The balance of components is powered by 120V obtained by tapping one leg, L1, of the circuit. An internal transformer provides low voltage power to the control portion of the circuit.

- Read and follow installation instructions be fore plugging or wi ring in machine to electrica l circuit. Warranty will

INSTALLATION INSTRUCTIONS WARNING:

1) Connect brewer to water line as described in “PLUMBER’S INSTALLATION INSTRUCTIONS”. Connect to suitable power supply as described in “ELECTRICAL HOOKUP”. Turn power switch on for tea brewer and hot water machine, the tanks will begin to f ill. The blue filtering light will indicate filling is in process. Time required to f ill the tanks is about 4-1/2 minutes. Fill times much shorter or longer than noted may indicate the PDS valve is out of calibration. The PDS valve is the flow control device located on the rear of the machine and is factory set to the correct flow rate. See the “PDS VALVE CALIBRATION” section for information on setting the proper flow control rate (tea machine).

Water levels in the tea brewer & hot water faucet tank are independently controlle d by level probes which sense whe n water contact is made. A maximum run time of six minutes is programmed into the tea brewer for the initial fill cycle to prevent flooding should an error occurs. Should the tea brewer call for water for a time period in excess of 6 minutes the brewer will shut down the fill circuit and display an Er1 message. S ee the “E RROR MESSAGES” section for instructions on how to cl ear the error and possible causes.

2) Once the water level has reached the proper water levels the tank heaters will begin to heat the water to the preset temperatures. This prevents premature failure o f the element by heating it dry . This prob e will also call for p ower to be shut off to the element should the water level fall below it (tea brewer). Heating time will be approximately10 minutes. The heating circuit has a maximum continuou s run time of 30 min utes. Should the tea brew er call for heat for a time p eriod in excess of 30 minutes the brewer w ill shut down the h eating circuit a nd display an Er2 message. See the “E RROR MESSAGES” sectio n for instructions on how to clear the error a nd possible causes. The heating light on the faceplate will indicate he ating status. As the preset temperature is approached the light will begin pulsing as the power to the element is cycled on and off.

- Read and follow installation instructions before plugging or wiring in machine to electrical circuit.

Power to brewer must be OFF before proceeding with plumbing installation.

3) Place a suitable container in place below the brew basket to catch water. Depress one of the brew start/stop switches. If the brewer is up to temperature t he brew cycle will begin immediate ly , if not the brew er w ill go int o autoarm mode. In auto arm mode the heating light will begin to flash but the fill portion of the brew cycle will not begin until the optimum (preset) temperature has been reached. In higher altitude locations (5000 feet above se a level) the tank temperature may h ave t o b e adjusted lower to prevent boiling. Compare the delivered volume to the programmed volume for the brew selected. Factory settings are 30 oz for the half pot of tea and 60 oz for th e f ull pot of t ea. If volume delivered varies substantially from the preset volume the PDS valve is out of calibration. See the “PDS CALIBRATION” section for information on setting the proper flow control rate. See the “PROGRAMMING” section for instructions on adjusting the preset tank temperature and brew volume(s).

TEA MACHINE OPERATION INSTRUCTIONS TEA PREPARATION PROCEDURES

1) Place filter into brew basket.

2) Put the proper amount of tea into filter for volume to be brewed.

3) Slide the brew basket into holder above the lower warmer plate.

4) Place an empty carafe in place below the brew basket.

5) Press brew start/stop switch for brew volume desired. A brew cy cle may be initiated even if the heating light is on. Read y light ind icates the tank has reached the preset temperature.

If the autoarm feature is enabled and the tank has not reached brewing temperature the heating light will begin to flash indicating that the brewer is heating and will begin to brew immediately after the heating cycle is complete. Do not remove decanter. Brew cycle may be canceled by depressing the brew start/stop switch. Heating light will cease flashing but may remain on or may pulse if preset temperature has not been reached.

6) Hot water will be delivered thro ugh t he spra yhead. This distributes the hot water over the tea within the br ew basket. The brewed tea will drain from the brew basket into the decanter below.

7) The LED display will co unt the brew ti me down unt il all the liquid has fin ished flow ing from the brew basket. Do not remo ve decanter until the brewing process has stopped and all liquid has stopped flowing from the brewbasket. See the “PROGRAMMING” section for instructions on adjusting the visibrew time. Visibrew is the time allowed after the brew cycle for the hot tea to finish draining from the brewbasket.

8) After the brew cy cle has completed th e audible beep will sound and the brew basket icon will flash. Press t he quality b utton to cancel the beep and to turn off brewbasket icon. To clean brew basket simply remove from brew rails and dump filter into waste basket. Rinse basket if desired and replace in brewer. The brewing process, as described above, can now be started again.

QUALITY CHECK

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 w ill show the pro grammed volume in ou nces th at brew one (TEA 1/2) is set for.

TEA BREWER FEATURE DESCRIPTIONS

The AKPA brewer incorporates the latest features in brewer contr ol technology. A lthough providing for enhan ced functionality brewer controls remain intuitive a nd set up of key operating parameters couldn’t be easier. Multip le brew volumes, visa-brew delay, tank tempe rature set point, br ew mode, filter p arameters and mor e are all set from the front cont rol 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 turne d off or set for any volume from 30 ounces to 255 ounces for the ultimate in fle xibility . Selected brew volume is converted to br ew time inter nally 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 temperature and the total number of brew s for each side. To a ctivate the display depress the quality check button. When the button is depressed the display will show the programmed volu me in o un ces t hat br ew one (T EA 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 numb er 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 w ater delivery portion of brew cycl e to allow for the cof fee to finish draining from the br ew basket. The digital countdown, and the delay in the audible coffee rea dy si gnal, aid in preventing premature removal of eith er 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: Br ewer temperature is set at 203 de g and Hot Water Dispenser is set at 205 d eg. In higher altitude locations, over 3500 feet a bove sea leve l, the te mperature will n eed to be a djusted down to prevent b oiling.

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 portio n of the brew cy cle is d elay ed. The heating lig ht will begin to flash indicating that th e 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 cy cle w ill resume. Auto arm may be overri dden by pres sing and holding the appropriate b rew button for several seconds until the brew cycle starts.

Pre-infusio n mod e – This mode delivers a small a mount of hot water over the coffee grounds and the n pauses to allow w etting of the brewed product and to allow the product to absorb th e water before continui ng. After this pause the brew cycl e resumes normally. Pre-infusio n can y ield 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 Bre w M ode – This mode cy cles the fill valve o n and off during the brew cy cl e. This sl ows the entry of cold water into the tank and minimiz es the mi xing action ca used by introducing a large volume of cold w ater into the tank at on e 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 throu ghout the brew cy cle to pro vide a pulse after eve ry 3 0 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.
