2. Reconnect the UV wiring connectors in the top of the unit.
3. Turn ON the water supply and plug in the unit.
4. The unit will fill the reservoir with product water from the RO system for a first time rinse.
5. Once filled, dispense ½ of the reservoir with the Cold dispense button and ½ the reservoir with the Hot dispense
buttons (push both to dispense).
6. Allow the unit to refill the reservoir a second time using the installed RO system for a final rinse.
7. Once the reservoir is full, turn ON the red switch at the rear of the unit. This will start the heating and chilling
process.
8. Visually verify that the UV Lamp is working – look for a faint blue glow underneath the silicon fitting on the top of
the UV Lamp.
9. Verify that the compressor starts by feeling the head of the compressor for vibration. The temperature in
the cold tank should reach its target temperature within 45 minutes. When the unit has reached target cold
temperature, the compressor will cycle off. The hot tank will take considerably less time to reach its target
temperature of 181° F.
10. After 45 minutes, verify proper heating and chilling.
11. Turn the Red Power Switch OFF.
12. Hold a pitcher under the Hot dispensing faucet. Depress the Hot unlock button, followed by the Hot dispense
button, and allow water to continuously run through the hot tank until the water runs cool from the faucet. This
is done to avoid scalding during draining.
13. Disconnect the power cord from the 120 volt electrical outlet.
14. Turn off the water supply to the unit.
15. Disconnect the water supply from the unit.
16. Open the hot and cold tank drain caps on the back of the unit (Figure 2, items 27 and 28) and drain
completely. Wipe down any excess water inside and around the unit and replace the lower front panel.
17. The PURA Ultimate should be flushed within 24 hours.
NOTE The connectors only attach one way.
NOTE Make sure the Red Power Switch is OFF.
NOTE Time your preparation to make this an overnight fill.
NOTE The RO system will take three to five (3-5) hours to fill the reservoir. To speed this first rinse
refill time, use an alternate source of high quality RO water delivered directly to the reservoir,
bypassing the installed RO system.
cAUTION! NEVER look directly at a working UV Lamp as eye damage will occur.
