MACHINE SETUP
PLUMBER'S INSTALLATION INSTRUCTIONS
CAUTION: Power to machine must be OFF before proceeding with plumbing installation.
1) Flush water line before installing machine. Machine should be connected to COLD WATER
LINE for best operation.
2) Water pressure should be at least 20 psi. 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 machine.
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 machine. 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 machine has a power cord attached for 120 volts. Machine should be connected to the
appropriate receptacle type. A wiring diagram at the rear of this manual illustrates the complete
machine wiring
INSTALLATION INSTRUCTIONS
WARNING: - Read and follow installation instructions before plugging or wiring in machine to
electrical circuit.
1) Make sure machine is level. Connect machine to water line as described in “PLUMBER’S
INSTALLATION INSTRUCTIONS”. Connect to suitable power supply as described in
“ELECTRICAL HOOKUP”. Tank will begin to fill when connected to power supply. The
display will indicate ‘fill’ when filling is in process. Time required to fill the tank is about 4-
1/2 minutes.
2) Water level in the tank is controlled by a level probe which senses when water contact is
made. A maximum run time of six minutes is programmed into the machine for the initial fill
cycle to prevent flooding should an error occur.
3) Once the water level has reached the proper water level the tank heater will begin to heat the
water to the preset temperature. 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 probe not
detect water for 3 minutes. Heating time will be approximately 20 minutes. The heating circuit
has a maximum continuous run time of 45 minutes. Should the machine call for heat for a
Time period in excess of 45 minutes the machine will shut down the heating circuit and
display an Er5 message. See the “ERROR MESSAGES” section for instructions on how to
clear the error and possible causes. The heating icon (thermometer) on the faceplate will
indicate heating status. As the preset temperature is approached the icon will begin pulsing
as the power to the element is cycled on and off.

Service Notes
1) Should water overflow the tank into the float switch, the water fill valve
(solenoid) circuit is interrupted. This is a safety feature to prevent as spill from
occurring should the water level-probe system malfunction (ER6). To empty the
overflow cup, unplug the power cord and loosen screw on the sheet metal cup
holder bracket. (see illustration on page 9) and empty cup.
2) The heater element is protected by a hi-limit manual reset thermostat (ER5).
Error Modes - To reset an error condition simply power the machine off and
back on. If the error continues, check the condition of all sensors,
hardware & wiring.
