Rainfresh Twist QS1 Installation And Operating Instructions Download Page 3

STARTING UP

-   Reconnect the QLV cartridge by turning it  to the right until it stops turning and the lock marks on the cartridge and head line up  

  (lock position)

-   Turn the faucet handle to ON position. 

-   Turn saddle valve handle clockwise. After some free rotations, the needle on the valve will start to pierce the pipe. Continue to rotate  

  the handle until it can go no further. You have now pierced the pipe, but the valve is closed. Now turn handle counter clockwise all  

  the way to open and start water flow. 

-   Close faucet and check all connections for leaks. Carefully retighten any leaking fittings. It is a good idea to check the unit a few    

  times for slow leaks shortly after installation. 

Flushing and conditioning

: Allow water to flow from the faucet for 10 minutes to flush unit before beginning service. 

YOUR UNIT IS NOW IN OPERATION.  

Note:

 Some carbon fines may persist for several days and the water may also appear milky because of trapped air bubbles coming out 

of the unit. These are harmless and frequent running of the unit will clear them more quickly. Running the unit for extended periods of 

time will NOT help.

CONNECTING THE SYSTEM TO THE FRIDGE (Model QS1K only)

If you also wish to enjoy filtered water from your fridge water dispenser, then:

-   Measure and check the remaining 1/4”  tubing to ensure that it is long  

 

  enough to connect the filter unit to your fridge. Note: If your fridge is farther  

  away, you may require additional ¼” tubing (not included).

-  Shut the water off by turning the handle on the saddle valve clockwise until  

 stop. 

-  Open the faucet to release water pressure.

-  Cut the tube connecting the faucet with the outlet fitting at the center, 

  making sure that your cut is straight. Caution: Do not cut the tube at an angle  

  as that can cause a leak.

-  Connect the open ends of the tubing now to the ¼” union tee (2612) 

  included with the unit.

-   Now connect the open end of the union tee (2612) to your fridge using 

  the 1/4” tubing.

SETTING THE RAINFRESH FILTER LIFE MONITOR (Models QS1 and QS1K only)

Press and hold black monitor button. The orange LED will glow and after 5 

seconds it will blink 4 times and turn off. Now release the button as the monitor 

has been reset. The monitor tracks both the gallons used and time. When either 

350 gallons or 6 months have expired the orange LED will blink every 5 

seconds advising you to replace the cartridge.The LED will continue to blink until monitor is reset as above. Note: Excessive sediment 

may cause more frequent filter cartridge replacement. 

Monitor Battery

 - After approx 2 years yellow LED will blink every 5 seconds advising you to change battery.

To replace battery

 - Remove head cover insert (2713) by gently pulling away the insert from the head. Insert new battery (2545) into 

battery slot between contacts with + side out and reattach cover insert to head assembly.

To test battery

 – With faucet off, press the black button for two seconds or less. If the orange LED lights up then power is on and 

monitor is working. If LED does not light then battery is expired and must be replaced. NOTE: If faucet is on and water is running, LED 

will not light if button is pressed.

REPLACING FILTER CARTRIDGE 

For best results, the QLV filter cartridge in Model QS1 or QS1K must be replaced after 350 gallons (1324 L approx) or 6 months 

whichever comes first . This will be signaled by the orange LED blinking every 5 seconds. The QLV cartridge for Model  QS1X must be 

replaced after 250 US Gal (946 L) or 4 months. 

There is no need to shut water off for cartridge change.

Note:

 Filter cartridge life depends on water quality. Excessive fine sediment can substantially reduce the filter cartridge life. This will be 

signaled by a sudden drop in water flow or no flow from the faucet before the 6 month life is up. If your water has excessive sediment, 

we recommend installing a Rainfresh whole house water filter available from the same retailer where you purchased this unit. Call 

Rainfresh for assistance in locating a retailer and product selection.

To replace filter cartridge

 - simply hold the cartridge and turn about 1/4 turn left and lower it away from head while holding it 

vertically to retain water.  Empty the old cartridge in the kitchen sink by holding it upside down and discard. Use a dry absorbent cloth 

or a paper towel to wipe off any water that may fall on the cabinet floor.   To install new filter cartridge, turn it to the right until it stops 

turning and the lock marks on the cartridge and head line up (lock position). The cartridge is now locked in place. 

MAINTENANCE / PRECAUTIONS

1) Do not subject unit to freezing temperatures at any time. 

2) Do not clean housing with organic solvents such as those found in sprays for cleaning products or insecticides as these may cause 

  cracking or crazing and lead to failure and leakage.

3) Replace filter periodically as above.
