Flush and Return to Service
1. Slowly turn ON the water supply. Open the ball valve on the top of the full RO water storage tank.
2. Flush 1–2 gallons (4–8 liters) of hot water, 1–2 gallons (4–8 liters) of cold water and 1 gallon (4 liters) of
water through the unit to flush the new water treatment components and the water in the unit. (See page
12 for details on the operation of the control buttons). Verify the water is running clear of any carbon fines or
color.
3. Turn ON the Red Power Switch to start the chilling and heating processes.
4. Verify that the compressor and heater are both working: place a hand on top of the compressor to feel for
vibration, then dispense water from the hot tank (after five minutes), noting a temperature increase in the
water.
5. Visually inspect water connections for any leaks.
6. Remove the faucet nipple and inspect to see if there are any cracks or scratches or lime-scale build up on
the nipple, if so then replace it. If the faucet nipple is OK, sanitize it with a bacterial wipe or spray and put
back using clean latex gloves.
7. Remove and clean the drip tray and grill. If the grill is damaged or heavily stained it should be replaced.
8. Wipe all surfaces around the drip tray and faucet nipple area with a bacterial cleaning wipe or spray.
9. Return the drip tray to the unit.
10. Check that the UV lamp is functioning by observing a blue glow from the top of the UV cap.
11. Close the top cover and front cover of the unit.
12. Taste the water. Check the unit is clean and functions to the customer’s satisfaction. If you are not satisfied
with the quality of the water, check the filters and flush additional water through the unit. Answer any cus-
tomer questions regarding use of the unit.
13. Update service maintenance label.
