BREWER SETUP
PLUMBER'S INSTALLATION INSTRUCTIONS
CAUTION:
Power to brewer must be OFF before proceeding with plumbing installation.
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:
- Read and follow installation instructions before plugging or wiring in machine to electrical circuit. Warranty will
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.
INSTALLATION INSTRUCTIONS
WARNING:
- Read and follow installation instructions before plugging or wiring in machine to electrical circuit.
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 fill. The blue filtering light will indicate filling is in process. Time required to fill 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 controlled by level probes which sense when 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. See the “ERROR MESSAGES” section for instructions on how to clear
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 of the element by heating it dry. This probe will also call for power 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 continuous run time of 30 minutes. Should the tea brewer call for heat for a time period in excess of 30
minutes the brewer will shut down the heating circuit and display an Er2 message. See the “ERROR MESSAGES” section for
instructions on how to clear the error and possible causes. The heating light on the faceplate will indicate heating status. As
the preset temperature is approached the light will begin pulsing as the power to the element is cycled on and off.
