5. The filters were already installed in the unit at the shop during initial start up.
6. Plug the power lead into the back of the unit. As soon as you plug the unit into a suitable power supply (15A
GFI outlet is preferred), voltage will be available to the PCB and solenoid valves, and you can now start to
flush water through the machine.
7. The hot water temperature is set at 185°F (85°C) (+/- 5%) and the cold water temperatures is set at 41°F
(5°C) (+/- 5%)at the factory. It is not possible to adjust the hot water temperature.
8. Verify proper temperature at install.
CAUTION! The unit is now live. Take suitable safety precautions.
NOTE Do not turn on the red switch (heater and compressor switch) at the rear of the machine. This switch
should only be turned on once the hot tank is filled with water.
NOTE Do not adjust the cold thermostat past the factory set point of 41°F (5°C), as this may result in the
system freezing.
Flush and Fill the Unit
NOTE For units using RO treatment: Because the RO make-up rate is so slow, use a full storage tank (with
RO treated water) for the following fill and flush steps.
1. Connect the full storage tank of RO water to a tee installed ahead of the unit solenoids.
2. Slowly turn on the water supply and open the ball valve on the full RO storage tank.
3. Select the hot water option. Press and hold the dispense button to start flushing water through the filters and
hot tank.
NOTE It may take several minutes before the hot tank is full and water begins to flow from the dispensing
head. Flush one to two (1–2) gallons (4–8 liters) of water.
4. Select the cold water option. Press and hold the cold dispense button to fill the cold tank.
NOTE It may take several minutes before the cold tank is full and water begins to flow from the dispensing
head. Flush one to two (1–2) gallons (4–8 liters) of water.
5. Check the unit for any water leaks and ensure that all water fittings are secured properly.
6. Replace the lower front cover.
Heat and Cool the Water
1. Once you are satisfied that water is passing through both the hot and cold tank successfully, then turn on
the red switch (heater/compressor switch) located at the rear of the unit. The unit will now start to heat and
chill.
2. Heat the water to approximately 185°F (85°C) (+/- 5%).
3. Cool the water in the cold tank. When the unit has reached the set temperature, the compressor will stop
running. The temperature may continue to drop as any ice that has formed on the sides of the tanks will start
to melt and equalize the tank temperature.
