SYSTEM START-UP
Prior to start-up
1. Check all connections are secure.
2. Turn on feed water valve and check for leaks. (Turn off and correct leaks if leaks occur.)
3. Open valve on storage tank and open faucet until a steady stream of water flows. The faucet’s black dispensing lever can be lifted upward
(parallel with the faucet body) to keep the faucet open.
4. With the faucet open, tip unit on its side to purge any air in the system.
5. Close faucet and wait five minutes to see if leaks result.
Note: When the system is first turned on, water may intermittently “spurt” from the air gap opening on the side of air gap faucet. This is common and
should correct itself after an initial period of time.
CAUTION:
The RO membrane is shipped with a preservative in it. To ensure proper flushing of the RO membrane it is important to wait approximately
four hours before emptying each tank as described in the following flushing system steps.
FLUSHING SYSTEM AND CHECKING OPERATION
To make sure RO system is operating correctly, follow these simple procedures:
1. Open faucet handle and allow tank to completely drain of water.
Do not use this water.
Note: When tank is empty, faucet will steadily drip. This is the rate the RO system processes water.
2. With faucet handle in “open” position, measure the rate of the steady drip from spout. Use a graduated cylinder and watch with a second hand to
calculate approximate production in gallons per day.
Note:
Milliliters per minute X 0.38 = GPD.
Ounces per minute X 11.2 = GPD
3. Proceed to check reject flow rate by disconnecting tubing at drain connection and measure flow as described above.
Note: Proper ratio should be 2.5 reject water to 1 part of product water, on average.
4. Close faucet and re-inspect system for leaks.
5. Allow system to process water for approximately four hours, at which point tank will be practically full.
6. Open faucet again and allow tank to empty. Carbon fines (very fine black powder) from the carbon post-filter may be noticed. This is normal for
the first tank of water or after the carbon post-filter is changed.
Do not use this water.
7. Wait another four hours to allow tank to re-fill.
Note: If no objectionable tastes are noticed after second tank draining, RO processed water is ready for use. Otherwise, drain tank and re-fill for a
third time.
8. At this point supply line to ice maker connection (optional) may be opened.
