Flush the Cold Tank. Run several gallons of water through the faucet by dispensing cold water to
dilute and remove the sanitizer from the cold circuit. You can use chlorine test strips to evaluate the
water. Once the sanitizer odor/taste has been flushed out of the cold side of the machine, move to
the sparkling circuit.
21.
Flush the Sparkling Chamber. Dispense sparkling water until only gas comes out. Let the Sparkling
Tank regenerate. This should take approximately 1 minute, 20 seconds. Listen for the booster
pump to turn off. Repeat the sparkling water regeneration until the sanitizer odor/taste has been
flushed out.
22.
The sanitization process for the Cold and Sparkling Circuits is now complete.
Fill the Hot Tank
23.
Press the Hot Button (Button 3), followed by the main dispensing button to fill the Hot Tank. Water
will dispense from the faucet once the Hot Tank is full. Flush until water is clear.
WARNING!
HOT CIRCUIT IS NOT SANITIZED. WATER MUST EXCEED 171
o
F
Water in the hot circuit is not sanitary until the temperature over 171
o
F for 5 minutes.
Do Not Ingest and avoid contact until heater is turned on for at least 5 minutes.
UV System Functional Test
WARNING!
ULTRAVIOLET RADIATION.
Protect your skin and eyes against ultraviolet rays.
Never look directly at an operating UV light. Disconnect before removing.
24.
Dim or shield the overhead lights and peer into the machine, on top of the Cold Tank, at the UV
connector and Retaining Cap. The blue glow indicates that the lamp is lit.
25.
Find the white wires delivering power to the top of the lamp assembly. Follow the wires back until
the electrical connector is found. Disconnect the electrical connector and verify that the UV Lamp
alarm annunciates.
26.
Reconnect the UV Lamp wire connector, and cycle the Red Power Switch to clear the alarm.
Compressor Test
27.
Switch on the GREEN Compressor / Heater Switch (
I=ON)
. Always ensure
tanks are full of water before turning on the heater or the overload (high
limit) will open and require manual reset. Once the Compressor starts, the
fan condenser also will start. Verify the fan has started by feeling for the
discharge of air at the rear grill of the machine. Heat exchange is a signal
that the refrigeration system is working.
28.
Monitor the Cold Tank temperature on the front display of the unit by changing the Temp Display to
RANGING. It will take about 45 minutes for the unit to chill down to the default set point
temperature of 41
F assuming ambient inlet water of 75
o
F.
